65 Amazing Chemistry Experiments for Kids
Chemistry is so much fun, and we have tons of cool chemistry experiments to share with you. Like our awesome physics experiments , we decided we needed to put together a list of fun chemistry projects kids can do at home or in the classroom. Check out these examples of easy chemical reactions below!
65 Chemistry Experiments You Want To Try
We have divided our chemistry experiments below into chemical reactions, acids and bases, chromatography, solutions, polymers, and crystals. Some chemistry experiments also explore concepts in physics .
Chemical Reactions
A chemical reaction is a process where two or more substances react together to form a new chemical substance. This might look like a gas formed, cooking or baking, milk souring, etc.
Sometimes a physical change occurs, like our popcorn experiment or melting crayons, rather than a chemical change . However, these experiments below are all great examples of chemical change, where a new substance is formed.
CHECK OUT: Examples Of Physical Change and Chemical Change Examples
Can chemical reactions happen safely at home or in the classroom? Absolutely! This is one of the most fun parts of chemistry for kids, and you will find lots of ideas below for safe chemical reactions you can do with your junior scientists.
Acids And Bases
Acids and bases are important for many chemical processes in everyday life. An acid has hydrogen ions and can donate protons. Acids taste sour and have a pH from 0 to 7. Vinegar and citric acid are examples of acids.
Bases are molecules that can accept hydrogen ions. They have a pH higher than seven and can taste bitter. Sodium bicarbonate or baking soda and ammonia are examples of bases. Learn more about the pH scale.
Vinegar and baking soda experiments are classic acid-base reactions. You’ll also find experiments that use an acid such as vinegar or lemon juice. We have so many fun variations that your kids will love to try! Check out these acid-base chemistry experiments below.
Chromatography
Chromatography is a technique that involves the separation of a mixture into its parts so you can see each one individually.
A solution is a mixture of 2 or more solutes dissolved in a solvent up to its solubility limit. It most often refers to liquids, but solutions, gases, and solids are also possible. A solution will have its components evenly distributed throughout the mixture.
Chemistry experiments involving solutions are great for kids. Gather liquids you commonly find in your kitchen, oil, water, detergent, etc., and explore what dissolves.
A polymer is a huge molecule made of many smaller molecules layered together in repeating patterns called monomers. Putty, slime, and cornstarch are all examples of polymers. Learn more about the science of slime polymers .
Making slime is great for at-home chemistry! It’s also a classic middle school science demonstration for the classroom. Here are a few of our favorite slime recipes to get you started.
non-Newtonian Fluids
Learn how to make oobleck ! Explore polymers with a simple cornstarch and water mixture.
A crystal is a solid material with a highly ordered internal structure of atoms, molecules, or ions held together by chemical bonds. Grow crystals and observe them by mixing a super-saturated solution and leaving it for several days to let the crystals form.
Simple to grow and taste-safe, a sugar crystals experiment is more accessible for younger kids, but you can also try growing borax crystals for older kids.
Check out our fun theme variations of growing crystals too!
Chemistry For Preschoolers
Let’s keep it basic for our younger or junior scientists! Chemistry is all about how different materials are put together and what they are made up of, like atoms and molecules.
What can you do with your youngest scientists? While working 1-1 or in a very small group is ideal, you can explore chemistry in a few fun ways that don’t require a lengthy setup or a lot of directions to follow. Do NOT overcomplicate the ideas!
Take, for example, our very first baking soda science experiment (age 3). So simple to set up, but so lovely to watch the amazement on my son’s face.
Check out these fun ways for preschoolers to explore science…
- Make liquid mixtures! Mix water and oil in a jar, let it rest, and observe what happens.
- Make solid mixtures! Mix two solid items and observe the changes!
- Mix a solid and a liquid! Add ice to a drink and observe the changes!
- Make a reaction! Set up a tray with baking soda in small cups and colored vinegar in small cups with pipettes. Mix and observe!
- Make oobleck ! Mix cornstarch and water for a weird and messy science activity.
- Explore characteristics of things! Use new science words to describe how different materials feel. Explore squishy, hard, rough, smooth, wet, etc…
Much of preschool science is about you sharing new experiences with them that are relatable and simple. A sk questions, share new words, and offer verbal prompts to get them to communicate with you about what they see!
Chemistry Science Fair Projects
Science projects are excellent tools for older kids to demonstrate their knowledge of science. They can also be used in various environments, including classrooms, homeschools, and groups.
Kids can take everything they have learned about using the scientific method , stating a hypothesis, choosing variables , and analyzing and presenting data.

From colored fire to magic rocks these 10 chemistry demonstrations , experiments, and activities are sure to wow kids and adults alike.
Make Colored Fire
Fire is fun. Colored fire is even better. The best part is, the additives for this project are readily available and safe. They generally don't produce smoke that is any better or worse for you than normal smoke. Depending on what you add, the ashes will have a different elemental composition from a normal wood fire, but if you're burning trash or printed material, you have a similar end result. Colored fire is suitable for a home fire or kid's campfire, plus most chemicals are found around the house (even of non-chemists).
Make the Classic Chemical Volcano
The classic volcano is the old-school chemistry lab volcano, which is also known as Vesuvius Fire. The mixture glows and gives off sparks as it decomposes, and makes its own cinder cone of green ash. The compounds used in the classic volcano are toxic, so this is a chemistry lab demonstration and not a great choice for the armchair scientist. It's still cool. It involves fire.
Of course, the baking soda volcano is always safe, non-toxic option, too!
It's Easy To Make a Borax Crystal Snowflake
Growing crystals is a terrific way to examine the structure formed when molecules bond together. The borax snowflake is a favorite crystal project.
This is a crystal-growing project that is safe and easy enough for kids. You can make shapes other than snowflakes, and you can color the crystals. As a side note, if you use these as Christmas decorations and store them, the borax is a natural insecticide and will help keep your long-term storage area pest-free. If they develop a white precipitant, you can lightly rinse them (don't dissolve too much crystal). These snowflakes are super sparkly!
Make a Borax Crystal Snowflake
Make Liquid Nitrogen Ice Cream or Dippin Dots
There are lots of fun chemistry ice cream recipes , but the liquid nitrogen versions are the exciting ones.
It's the quick way to make ice cream, plus, if you use your imagination, you can come up with lots of other fun activities involving liquid nitrogen . It's easier to get and transport liquid nitrogen than you might think. Try the basic liquid nitrogen ice cream recipe and then show off your skills by making homemade Dippin' Dots ice cream.

- Make Homemade Dippin' Dots
Oscillating Clock Color Change Chemical Reactions
Of all the chemical reactions, the color change reactions may be the most memorable. The oscillating clock reactions get their name because the colors transition between two or more hues as the conditions change.
There are many color-change chemistry reactions, pretty much using acid-base chemistry. The Briggs-Rauscher reactions are nice because the colors oscillate on their own for a long time (clear → amber → blue → repeat). The blue bottle demonstration is similar, and there are other colors you can produce depending on the pH indicator you select.
- Briggs-Rauscher Oscillating Clock
- Blue Bottle Color Change Demonstration (blue - clear - blue)
- Christmas Chemistry Demo (green - red - green)
- Hot and Cold Valentine (pink - clear - pink)
There's More Than One Way To Make Slime
You don't need to have esoteric chemicals and a lab to have a good time with chemistry. Yes, your average fourth grader can make slime. It's one of the first chemistry projects many kids try. That doesn't mean it's any less fun when you're older.
Recipes for Making Different Types of Slime
Write Secret Messages With Invisible Ink
Experiment with invisible ink to see how chemical changes affect the color of materials. Most invisible inks work by subtly damaging paper, revealing the message by making the alterations in the paper apparent. Other versions of the ink appear clear until an indicator chemical is applied, which reacts with the ink to make the message appear.
A variation is to make disappearing ink. The ink is a pH indicator that becomes colorless upon reacting with air. You can make the color reappear by applying a basic solution.
- Make Invisible Ink
- Make Disappearing Ink
Make Chemical Cold Packs and Hot Packs
It's fun to mix chemicals together to produce temperature changes. Endothermic reactions are those that absorb energy from their environment, making it colder. Exothermic reactions release heat into the environment, making it hotter.
One of the easiest endothermic reactions you can try is mixing water with potassium chloride, which is used as a salt substitute. A simple exothermic reaction you can try is mixing water with laundry detergent . There are many more examples, some much colder and hotter than these.
- Endothermic (Cold Pack) Reactions To Try
- Steel Wool Exothermic Reaction
- Hot Ice Exothermic (Hot Pack) Reaction
Make a Smoke Bomb and Colored Smoke
Chemical reactions are the basis for many "magic" tricks, pranks, and fireworks. One impressive chemistry project, which can be used for tricks or celebrations, is making and lighting smoke bombs.
A smoke bomb is a good introduction to pyrotechnics because it does not explode. It doesn't produce a lot of fire. It does give off copious amounts of smoke, so it's best to light your chemical masterpiece outdoors.

- No-Cook Smoke Bomb Recipe
- Make Colored Smoke
Grow a Chemical Garden With Magic Rocks
This is the classic chemical garden or crystal garden, though it's more about precipitation than crystallization.Metal salts react with sodium silicate to form fanciful waxy-looking towers.
There are many inexpensive Magic Rocks kits for sale in stores and online, plus you can make Magic Rocks yourself with a few simple chemicals.

50 Chemistry Projects That Will Amaze Kids!
February 26, 2019 by Ana Dziengel 5 Comments
Chemistry projects feel like magic , do they not? If you think about some of your favorite science projects, the ones you love to try with your kids or the ones that amazed YOU as a kid, more likely than not most of them involved chemistry.
Now I know a lot of us associate chemistry with lab coats, beakers and specialty ingredients but the reality is there are so many chemistry projects you can do using very simple, easy to find ingredients, often found in your own pantry. And since these types of simple chemistry projects use relatively safe ingredients, they are perfect to try with younger kids, ie. preschool and elementary aged children! In fact I think it’s so important for young kids to have a positive association with chemistry from a young age that fosters a love of this branch of science.
When most children are finally exposed to chemistry in school, it is at the high school level where the subject turns complex quickly; hopefully giving kids a chance to have fun at young age mixing up concoctions and watching chemical reactions will help carry their interest through the more complicated days of study ahead.
This post is a GIANT compilation of chemistry projects that would be great for the science fair, classroom demos, or at home science with your kids.
Before we get started let’s talk a little bit about what chemistry is and for parents I also included a section covering How to Do Chemistry Projects at Home. If you are a classroom teacher you can skip this section and head right to the projects here.
What is chemistry?
Chemistry is the branch of science that studies matter (anything that has mass and takes up space) and its properties, and how different substances (especially molecules and their atoms) interact, combine, and change to form new substances.
Here are some important definitions to know when working on chemistry projects:
- Element A substance that cannot be separated into any further substances. There are 120 known elements.
- Atom The smallest particle of an element
- Molecule Groups of atoms held together by a chemical bond.
- Ion An atom or molecule that has an electric charge
While most people think of chemistry purely in terms of chemical reactions, chemistry also covers the study of the states of matter as well as the density of substances.
The five branches of chemistry are:
- Analytical chemistry
- Physical chemistry
- Organic chemistry
- Inorganic chemistry
- Biochemistry
Read more about what each branch covers here.
How to Do Chemistry Projects at Home
Many chemistry projects can be done at home using simple materials and are a great way to foster a love of science in kids! I wholeheartedly believe that a wow factor in a project engages and inspires kids to learn more. If you want to try chemistry projects at home here are some suggestions and precautions:
Safety First
Even though most of the projects in this list use safe, easy to find materials they should be used with safety precautions and under adult supervision. Why? Sometimes the chemical reaction that ensues can irritate the skin or eye, can be harmful if swallowed, or is just plain sticky or messy and adults should be on hand to supervise use . Also be advised that there are a few projects on this list that do use materials that are unsafe for kids to handle. These projects are meant to be demonstrations only and are labeled accordingly.
- Use household items for chemistry The classic chemistry project that never fails to impress is the reaction of baking soda (sodium bicarbonate) and vinegar (look for a number of variations on this classic in our Acids and Bases section) but there are lots of other great ingredients for chemistry to find in your kitchen including sugar, salt, yeast, lemons, dish soap, milk, Kool- Aid, cabbage, gelatin, and food coloring to name a few…before you order any materials online, try some projects with pantry essentials.
- Safety Goggles
- Large plastic beakers
- Prepare for mess Since a lot of chemistry involves reactions and the ensuing mess, be sure to choose a place in your home that you can easily clean up and where you won’t worry about getting dirty. A patio, breakfast area, or the garage are great choices.
- Generous work area Be sure to have a large table available so everyone has plenty of room to work and/or view projects without bumping into each other.
- Access to Water Clean up is always easier with water at the ready! Choose a location near a hose or shop sink.
Managing Messes
- Hose it down Depending on the project I suggest doing super messy chemical reactions outside. That way spills can be hosed down easily.
- Painter’s Tarp & Trays If you cannot go outside a large plastic painter’s tarp is a great way to contain spills and mess. I also highly recommend doing projects on trays or cookie sheets. The raised edges help contain bubbly brews and are easy to dump out and wash.
- Dump station Have a bucket nearby to act as dump station for liquid reactions. Bring it around a table and dump at each station.
- Think about disposal Vinegar kills grass! Slime bits clogs drains! Be sure to consider where you can dump out the liquids safely.
Chemistry Projects for Kids
The following chemistry projects for kids are sorted by topic: Chemical Reactions, Acids and Bases, Carbon Reactions, Chromatography, Colloids & Solutions, Polymers, and Crystals.
Please note that many if these projects could fit in two or more categories in this post as they demonstrate various scientific and chemical processes. I only classified them once on this list.
Chemistry Projects with Chemical Reactions
What is a chemical reaction.
Chemical reactions occur when the chemical bonds in a substance are either destroyed or created. In other words the bonds in a molecule are broken during a chemical reaction and the atoms rearranged to create new molecules. Interestingly enough the number of original atoms does not change during the reaction, they are simply reconfigured.
An easy way to explain chemical reactions to kids is to use this analogy: Atoms are like letters, molecules are like words. Chemistry is like taking apart words and rearranging the letters to form a new word.
Read more about chemical reactions here.
Chemical Reactions Projects:
1. milk painting, 2. citrus battery, 3. elephant toothpaste.
<span data-mce-type=”bookmark” style=”display: inline-block; width: 0px; overflow: hidden; line-height: 0;” class=”mce_SELRES_start”></span>
4. Density Lava Lamps
To make a density lava lamp fill a plastic bottle with the following liquids: Clear corn syrup, water with a few drops of food coloring, and layer of vegetable oil. Be sure to leave a space at the top of the bottle. Wait until the liquids settle then add in a tablet of extra strength alka seltzer. Watch as the alka seltzer and water react and bubble up through the oil layer. To see this in a step by step video check out this video (Pssst this is one of our students!!!)
5. Plastic Milk and Curds & Whey Experiment
6 . color mixing.
Pour water into three clear plastic cups, then add blue, red, and yellow food coloring to each. Have an additional cup full of uncolored water available as well. Give your child an empty ice cube tray and pipettes and let them create different colors by mixing different ratios of two different primary colors in each ice cube compartment. The secondary colors are new colors created from two primary colors. This is a simple visual of how chemical reactions work.
7. Chemistry Clock
8. blow balloons with yeast and sugar, 9. shiny pennies.
- Collect dirty tarnished pennies.
- Pour different acidic liquids into shallow containers. Try vinegar, salsa, lemon & lime juice.
- Add a teaspoon of salt to each container and stir to combine.
- Place a handful of pennies in each container and soak for 5 minutes.
- Remove them from the solution and rinse in soapy water. Let dry on separate paper towels.
- Compare the results! Which ones are shiniest? Which are dull? Did any turn green?
Acids are corrosive and sour tasting. Liquids such as vinegar, lemon juice, and tomato juice are acids. Pennies are made from copper which tarnishes (turns dark) when exposed to oxygen over time. Placing the copper pennies in an acid will clean the copper oxide off them and make them shiny again.
Learn about Acids and Bases
Most liquids are either an acid or a base. Liquids with lots of hydrogen ions in them are considered acids. Liquids with many hydroxide ions are bases. Scientists use a scale called the ph scale to measure how acidic or basic a liquid is. The more hydrogen ions in a liquid the more acidic it is and ranks low on the ph scale. The more hydroxide ions in a liquid the more basic it is and ranks high on the ph scale. You can see what that looks like here.
When acids and bases are mixed chemical reactions occur and the solution becomes neutralized.
Acid and Bases Projects:
1. baking soda & vinegar volcano, 2. lemon volcano, 3. the colorful cabbage juice science experiment and acid base experiment with cabbage, 4. dancing rice, 5. green eggs & ham, 6. bubbly citric acid brew , 7. baking soda vs baking powder science experiment, 8. exploding bags, 9. rainbow rubber eggs , 10. surprise eggs , 11. rainbow wizard’s brew, chemistry projects with fire (carbon reactions).
Carbon is the most important element for life. Chemicals that contain carbon are called organic compounds. Carbon has two main forms: The first is in the hard form of diamonds and graphite, and the second is the impure form found in charcoal, coal and soot.
SAFTEY WARNING: Carbon reactions are always fascinating to watch however the presence of fire means that these experiments must be supervised by adults at all times!
Carbon Reactions Projects:
1. smoking fingers, 2. fire snake, 3. silver egg, 4. invisible ink, chromatography.
Chromatography is the process of separating mixtures. We usually think of it in terms of color hence the prefix -chroma, however in chemistry is means simply a method of separating mixtures by letting them slowly move past each other. It applies to both liquids and gasses. This is wonderful in-depth explanation of chromatography.
Chromatography Projects:
1. chromatography .
In this project you will separate the color black into other colors. Fold a coffee filter in half. Fold in half two more times until you have a triangular shape. Color the tip of the coffee filter with washable black marker. Get a good coat of ink on the filter. Add a small amount of water to a plastic cup. Place the black tip of the coffee filter in the cup Wait and observe. Come back to the filter after an hour or two and see what happens to the ink. As the coffee filter absorbs water through capillary action, the black ink moves through the filter and is separated by the water into other colors. You should see blue, green and even red as the water separates the ink.
2. Chromatography Flowers
3. chromatography art, 4. chromatography bags, colloids and solutions/solubility.
Colloids and Solutions are two types of homogenous mixtures.
- Colloids are mixtures in which a small particles of a substance are suspended throughout another substance but not chemically bonded. They are stable though and do not separate. Examples of colloids are gelatin, butter, mayonnaise, fog and smoke.
- Solutions are mixtures in which the particles of one substance are completely dissolved in another substance. The solute is the substance being dissolved and the solvent is the substance doing the dissolving. An example of a solution is saltwater.
If you want a more in-depth primer on solutions and colloids hop over here .
Colloid Projects:
1. colloid examples, 2. oobleck , 3. make butter , 4. gelatin streaking, solutions/solubility projects:, 5. ice sculptures , 6. ice cream in a bag.

7. Skittles Science
8. magical water blossoms <span data-mce-type=”bookmark” style=”display: inline-block; width: 0px; overflow: hidden; line-height: 0;” class=”mce_selres_start”></span>, 9. diffusion art, 10. paint solubility , 11. bleeding blossoms .
A polymer is a substance made up of a long chain of molecules. Polymers are typically flexible materials like plastic or gum.
The classic polymer kids LOVE to make is slime! Glue is already a polymer but when combined with sodium tetraborate (borax ) the protein molecules of the glue and the borate ions crosslink, making it harder for the molecules to move and forming the gooey, sticky, substance we know as slime.
Other polymers you are probably familiar with are plastic bags, balloons, instant snow, and even the powdery substance found in diapers that expands when wet.
Polymer Projects:
1. best basic slime .

2. Heat Sensitive Slime
3. diy bouncy balls, 4. magic plastic bag experiment, 5. instant terrariums, 6. how to make paper, 7. skewer through balloon , 8. dry erase figure and dry erase drawings, 9. recycled plastic flowers.
Crystals are a type of material that is formed by patterns of repeating molecules. There are four types of chemical bonds in crystals and therefore four categories of crystals. These are: Covalent, Molecular, Metallic, and Ionic Crystals. You can grow crystals by mixing up a super saturated solution (usually with a type of salt and water) and letting it settle over time so crystals will form. Check out the various types of easy to grow crystal below and go here to read more about the science of crystals .
Crystals Projects:
1. classic borax crystals , 2. overnight crystal garden, 3. egg geodes, 4. crystal wind catchers, 5. crystal landscapes, 6. candy geodes , 7. salt crystals, conclusion & more.
Alright you guys, do you feel like you have some good project ideas for exploring chemistry with kids? Many of these will make greats science fair projects. Be sure to start with them as a topic then start asking questions, form a hypotheses, and do some experiments.
Now I have to admit that I really fell in love with chemistry projects as an adult. Working with kids in camp, after school, and with my own kids at home I’ve had the chance to try fun chemistry projects and discovered that I love watching chemical reactions AND the reactions on the faces of kids and bystanders during demonstration or project!
If you have kids who fall in love with this branch of science please do check out the incredible book series Elements , Molecules , and Reactions by Theodore Gray (see the series in our Amazon science ideas list here ) The books are stunning, informative, easy to understand and, wait for it…funny!

Science Experiments at Home that take Less than 1 Hour
1. tie-dye milk.
Sounds delicious, right? You’re not actually drinking it, but instead watching science magic happens when you combine dish soap with milk and food coloring. This is a very pretty experiment that draws the focus and mind into what’s happening on the plate, and all because of a little chemistry with everyday items. Well, food dye may not be an everyday item, but it might be after your kids get a hold of this!
So, what’s going on here, scientifically-speaking? Milk is made up of two major ingredients: water and fat. When you add a little dish soap, it bonds with the fat in the milk so strongly that it literally pushes the food coloring and water away from the cotton ball. On a microscopic level, the dish soap is wandering around the milk, which causes the colors to swirl and swirl.
Questions to ask beforehand:
- Before knowing what will happen to the food coloring, ask the kids what they think will happen when dish soap mixes with milk.
- Since the major catalyst is fat in the milk, what would happen if you used other types of milk: Skim milk, soy milk, coconut milk?
You’ll need:
- Round cake pan or plate with high edges
- Cotton ball (some tutorials show cotton swabs)
- Dish detergent
- Different colors of food dye (three or four should do)
Procedure/Instructions:
- Fill the pan halfway with milk.
- Drip one color of food dye in one section of the plate away from the center. Four to five drops works and later you can play around with more or less. Do the same for the rest of the colors around the plate.
- Soak the cotton ball in dish detergent, and when you’re ready for action, place the cotton ball into the center of the pan.
- Watch the colors racing around, creating a psychedelic tie-dye effect!
- You can add more cotton balls throughout the dish to see more action.
- If some food coloring hugs the wall of the plate, take a cotton swab dipped in dish detergent and place it into the food coloring. It will move away!
2. Saturn’s Glowing Rings
I don’t know about you, but I love everything about space. This experiment shows you how Saturn’s rings are made of rocks and ice chunks even though they look so smooth in pictures. You’ll also see why there are big gaps in the rings. Younger kids take delight in using a flashlight and sprinkling powder, while older kids can get more specific with questions about Saturn and how the rocks and ice stay in orbit.
- Do Saturn’s rings give off their own light?
- Why are some rocks and ice chunks more lit up than others?
- Compare the results of light sprinkles to thicker sprinkles.
- Strong flashlight
- Powder (flour, baby powder, etc) in a shaker
- Very dark room
- Darken a room and set the flashlight on the edge of a table or counter, pointing it at a blank wall. Lay the newspaper on the floor between the flashlight and the wall.
- Turn on the flashlight and notice where the light comes from the flashlight and where it hits the wall. You should only see the light from these two places and not from the space between them. This shows you that the light travels through the air without being seen until it hits the wall. The light represents the sun’s light.
- Now to see how Saturn’s rings glow: Hold the powder shaker and sprinkle some powder over the beam of light where you know the light is traveling. You’ll notice the powder lights up and sparkles in the beam of light. The powder shows in glowing clumps, just like in Saturn’s rings.
3. Breaking Down Colors
We all know that the fun, vibrant colors we see in our lives are created by mixing the basic red, yellow, and blue. In this experiment, you and your child will learn which colors make up those fun shades they have in their art supplies. This also teaches some basic chemistry and uses materials you already have at home. It can be done very simply and expanded to create a large-scale investigation if you love it.
- Which colors separate out first?
- Is the same order for each test?
- Which colors make up the original shade?
- Do the different types of color (pen, pencil, paint) separate in the same way or differently?
- Are some separated in a shorter space are the colors the same mixture?
- Coffee filters
- Color sources (markers, colored pencils, paint, etc.)
- A plain pencil
- To complete this experiment, cut the coffee filters into strips, mark one end with a line the same distance from the bottom on each strip.
- Color in each strip (between the bottom and line) with your colors, and write at the top what the color and source are (e.g., purple marker).
- Place each strip in a glass and help it to stand up by folding the top over a pencil (a chopstick, table knife, or any long narrow object will also work) so that it stands up in the glass.
- Fill the glass up to the top of your colored block, and wait. The water will move up the filter, and the colors will separate out as it goes.
- Remove the strip once the water gets near the top of the strip to stop the experiment.
To make this a true experiment, we recommend testing multiple colors and using markers, colored pencils, and paint (as some starting examples). You could test the same colors from each type of art supply to investigate whether they all use the same mix of basic colors to create the same end product.
This post has a nice full description of the methods if you need more detail.
4. Water Xylophone
This simple experiment will teach your child about sound and pitch using glasses, water, and something to act as a mallet. Don’t let the simplicity deceive you, there are a lot of ways to experiment and learn through this process, and it also brings in an element of music that makes it interesting and engaging.
- Do you think more water makes the sound higher or lower in pitch?
- How do you think the shape or size of the glass will affect the sound?
- How should we arrange the glasses to play a simple song?
- Do you think this will work with a plastic cup, why or why not?
- Some glasses
- Something wood to act as a mallet (we recommend wood so you don’t break the glasses!)
- A great way to start is with glasses that are the same size, shape, and material, and filling them with different amounts of water.
- Have your child use the mallet to test how the amount of water affects the sound.
- From there, it’s a really simple extension to use different sized and shaped glasses (or any glass vessel like jars and bowls) to experiment with how the shape, size, and amount of water in the glass affect the tone.
To take this one further and really bring in the musical component, you and your child could work out a simple song and create the right tones to play it. If you or your child are musical, you could get very elaborate and creative (try googling harry potter or star wars theme songs on glasses, there are so many options that I couldn’t even choose one)!
5. Ultimate Bottle Flipping
Ah, bottle flipping. The fad that kids can’t get enough of, but parents are well and truly over. The constant thud of semi-filled water bottles being tossed (and hopefully landing upright) is guaranteed to send parents around the twist!
If you can stand it for a bit longer though, there’s a lot of STEM knowledge to be gained in this bottle flipping experiment. As we know, the aim of bottle flipping is to flip a partially filled water bottle underhand and get it to land upright.
In this experiment, kids will learn the importance of observing a result multiple times before changing a variable (the amount of water in the bottle).
- How much water should you put in the bottle?
- What is the ideal amount of liquid to get the perfect flip?
- What should be the ideal amount of water?
- Was their prediction correct?
- Why do they think the amount of water affects the chances of landing the bottle?
- A plastic water bottle
- Measuring jug
- Paper to record results
- Get the kids to start by flipping their bottle with no water in it at all. Kidspot recommends flipping it 50 times for each step, but you could do less if you need to.
- Try it again with 50ml of water.
- Keep adding more water until the bottle is full.
If they’re keen, you could try other types or sizes of bottles, or even try different liquids to see if that affects the results!
6. Rainbow in a Jar
This simple science experiment is not only very visually appealing, but it’s also a great way to learn about the density of liquids. Warning though, this one could get messy so make sure kids are in some old clothes and you might want to take it outside! I like this experiment because you’ll probably have most of the materials in your kitchen already!
- Which liquids they think will be heaviest?
- Which ones will be lightest?
- Why do they think that?
- A glass jar
- Food coloring
- Various liquids like honey, corn syrup, dishwashing liquid, olive oil, rubbing alcohol and water.
- Use the food coloring to make all your liquids a different color. A dropper comes in handy here, but if you don’t have one you can manage without.
- Slowly add each liquid to the jar (pouring into the middle of the jar is best).
- Soon, you’ll have different layers of colored liquid forming your very own rainbow in a jar.
You might even get them to draw a diagram of what they think the jar will look like at the end. They can compare this with the experiment results to see if their prediction was correct.
It might also help to talk to your kids first about what density is and how materials are all made of different amounts of molecules. The more molecules a liquid has, the heavier it will be. Playdough to Plato demonstrates a great way of introducing this concept using marbles.
7. Write Your Own Secret Messages!
We love science experiments that are made up primarily of supplies that you likely already have in your home.
- Why do you think this will work?
- Which liquid do you think will make the best secret message?
- Why do people write secret messages?
- Juice (eg. Lemon)
- Lamp (or anything else that can be used as a heat source)
- In order to complete this experiment, you’ll need to gather all of your supplies along with a piece of paper, some q-tips, and a lamp or other item that you can use as a heat source.
- Next, you’ll mix your lemon juice with a slight amount of water.
- Using your q-tip, use the mixture you’ve created to begin writing your message.
- Allow it to dry.
- Once dry, apply heat to it in order to get your message to appear.
Extend this project by attempting to write with a juice and water mixture, a milk and water mixture, or any other variation of the liquids we listed as necessary supplies!
8. Create Your Own Butterfly
Your little ones will love practicing their color mixing by creating their very own coffee filter butterflies. Hang them in the windows of your home to spread some cheer and to watch the sun flow through their beautiful wings!
- What colors can mix together to make other colors?
- How do butterflies fly?
- What do you think will happen when we add water to the markers?
- Water spray bottle
- Allow your child to draw on the coffee filter to their heart’s content.
- Spray it with water and allow the colors to mix together.
- Allow it to dry thoroughly.
- Once dry, fold it like a fan and then clip it in the middle.
Ta-da, you’ve created a beautiful butterfly!
9. Make A Duck Call
Give your family an excuse to head outdoors by allowing your children to craft their own duck calls. Test them out at a local pond and see if you can get the ducks to come closer to you for a healthy veggie snack!
- Do you think ducks will be able to hear us with this?
- What other materials do you think could make this noise?
- How is what we have created similar to a duck’s beak?
- Plastic straw
- Push down on the straw to flatten one end and then cut the flattened end into a point.
- Flatten out your straw and then blow into it.
- Feel free to experiment with different amounts of flattening and different point shapes to see how you can adjust the sound.
- When finished, take your duck call into the wild to test it out.
10. Make Ivory Soap Boats
Did you ever carve items out of soap at camp when you were a child? Give your child the same opportunity. Soap can be carved using safe items, like plastic knives.
- Why are we able to carve soap so easily?
- Do you think our boats float?
- Why do you think they float or sink?
- Carving tools (for kids)
- Allow your child to express their creative side by carving their boat out of soap.
- Once they have finished carving it, allow them to test them out in the bathtub. . Extend their learning by discussing density with them–the soap floats because it is less dense than the water.
11. Make Your Own Quicksand
As John Mullaney famously said, “I thought quicksand would be a much bigger problem in my adult life than it would have turned out.” For some reason, quicksand permeates children’s adventure stories – and their imaginations!
- Where can we find quicksand in real life?
- How do you think quicksand works?
- What do you think we will need to make our own quicksand?
- Cornflower (one cup)
- Water (half cup)
- A container
- To make your quicksand, you’ll need to mix the cornflour and water.
- Be sure to stir slowly in order to demonstrate – if you stir too quickly, it will become hard and you won’t be able to see it function the way it should!
12. Make Your Own Lava Lamp
We’ve tried this one in our classrooms, and trust us, our kids go wild year after year. Kids love making something that they can use as home decoration, and they love how easy it is to show new people – this is the experiment that lives on and on!
- How do you think density is involved in this experiment?
- Why don’t the water and oil mix?
- Why can’t we shake our lava lamps?
- Clear Plastic Bottle
- Vegetable Oil
- Food Coloring
- Alka-Seltzer
- Pour water into the plastic bottle until it is approximately one quarter full.
- Then pour vegetable oil in until the bottle is almost completely filled.
- Allow some time for the oil and water to separate.
- It is important that your children do not shake the bottle in this step. It will extend the experiment for no other reason than you waiting for the bubbles to dissipate.
- Add as much food coloring as your child deems fit and then drop a piece of Alka-seltzer tablet into the bottle for the lava lamp fun to begin.
13. Guess the Smell
This one will take a little more prep work, but it’s a great touchstone for your children to begin discussing one of their five senses: the sense of smell!
- What are examples of times we use our sense of smell?
- What other senses do we have?
- If you could only use one sense for the rest of your life, which one?
- Plastic Cups
- Smells (eg. coffee, cinnamon, vanilla, lemon juice)
- Place a variety of common smells in small plastic cups. We like to use coffee, cinnamon, vanilla, and lemon juice.
- Pour these in and place tin foil securely over the top of the cup.
- Poke small holes in the top of the foil.
- Secure the foil with tape (on the sides, not over the holes).
- Allow your children to guess the smells and record their findings on paper.
Home Science Experiments that take 1 to Several Hours
14. mangrove bioshield .
Ecologists and conservationists are pushing for more regulations in building and saving mangrove forests around coastal areas. The reason is represented in this STEM activity. The trees act as a mangrove BioShield (bio = life, shield = protection), showing how natural obstacles can prevent critical damage from marine natural disasters such as tsunamis.
The mangrove BioShield can be for older elementary kids through to high school. Obviously, the younger they are, the more parent involvement. This experiment is done twice to show the effects of having and not having a BioShield. The first part uses little to no trees, and the second uses a forest of trees and rocks.
- What will happen in a tsunami if the village is without a BioShield? And the village with a BioShield?
- Would a BioShield help with hurricanes?
- Would you want to encourage people to save manatee forests if they are beneficial?
- Medium to large clear, plastic container
- Newspaper – wad into balls, then cover half of the bottom container – this help to keep the ground sturdy
- Mud – cover the newspaper and press it in to form a slope down to the empty side of the container. The top side should be flattened for the cardboard houses, then it slopes down into the empty half of the container.
- Cardboard houses (use the bottoms of milk cartons for the house and popsicle sticks for the roofs, place houses on the mud towards the top of the high slope
- Model trees or leafy stems from plants – Different amounts for activity 1 and activity 2
- Several small rocks
- Cardboard – long enough to fit across the container and tall enough to hold it from out of the water
- Water – enough to go halfway up the slope
A tsunami without the mangrove forest – insert only one or two trees down the slope. Place the cardboard piece into the water end of the container and move back and forth to create waves. Notice how easy it is for the water to destroy the village you’ve created.
Repeat the process of constructing the village, but this time insert a lot of trees down the slope to where the water meets the mud. They need to be deeply rooted like mangroves, and I’ve found that aquarium plants work well for this reason. Place the rocks within the mangrove forest and in front of the trees. Add a little bit more water. Insert the cardboard again and move it back and forth to create waves.
15. A Greater Crater
When you look at the night sky and see the moon, one of the first things you notice is its craters. The moon is completely covered in them, and some are so large we can see them from Earth. Meteorites often make the craters that we see when they hit the surface, but it makes us wonder why some craters are so much bigger than others.
This experiment will help you to investigate one of the main reasons why craters come in different sizes.
- What causes craters?
- How big do the meteorites have to be to make a crater?
- What is it about the meteorite that causes the size of the crater?
- Paper to record your results
- Flat floor surface for the experiment, large enough for the newspaper to cover
- Shallow metal pan at least 2 inches deep
- Flour to fill 2 inches of the pan
- ¼ cup hot chocolate powder
- Mesh strainer or flour sifter
- Large marble (and others of varying sizes if comparing results)
- Metric ruler
- Tongs or long tweezers
- Pour the flour into the pan until it reaches 2 inches. Place the pan on top of the newspaper on a level surface.
- Sift a layer of hot chocolate powder over the flour (this is so you can better see the rays and other features of the craters).
- You will be dropping your marble from three different heights, then comparing the sizes of the craters. Measure the diameter (side to side) of the marble and record this on your paper as Marble 1. Hypothesize how large the crater will be and write that next to the diameter of Marble 1.
- Stand next to your pan and hold the marble at knee height above the flour. Drop the marble (do not throw it, just let it fall from your fingers) into the flour and study the shape of the crater. Look for a rim around the crater or any rays coming from the edges.
- Measure across the widest part of your crater, from rim to rim and record on your data sheet as Marble 1 – Knee Height – Width or something similar. You can also draw a picture of your results.
- Very gently use the tongs or long tweezers to remove the marble without destroying the crater.
- Repeat this procedure from waist height, shoulder height, top of head height. Make sure you aim in different parts of the flour so you don’t land on top of another crater. Record all of your results as the different heights you’re using.
- Compare your results.
- You can try again with a different sized marble as “Marble 2” to compare those results with each height as done with Marble 1.
Perhaps now, you’ll look at the moon a little differently!
16. Rube Goldberg Chain Reaction Machine
We’ve all seen them, some pretty far-out there chain reaction machines to complete simple tasks, usually in movies. But they are real , and are becoming even more popular now that we’re all stuck at home for a while. This is a fun way to explore physics with stuff you have at home.
Ask your child to decide what the end goal is (e.g. get the ball into the cup), and ask them to think about creative ways to make it get there. Working together, you can start with small pieces of a circuit to find out how your ball reacts to the set-up, and grow it from there. You can even refer to this video for more ideas:
- What will happen when the ball bounces off of this wall?
- How will these dominoes change the speed of the ball?
- What can we use to make sure that the ball goes in the direction we want it to at this point?
- What should we put here to get the best bounce?
- Paper towel
- Toilet paper tubes
- Fixed objects like walls or furniture
- Any other toys and materials that can be used to build your circuit
To make this a true experiment, it needs to include more than a one-off demonstration, and there are a lot of ways to accomplish this.
- Set up parallel courses and use different sized or weighted balls to go through the circuit.
- Set up one elaborate circuit and use different objects one at a time.
- Set up circuits in different ways to see how different set-ups affect your end goal.
Another experimental component is the process used to create a circuit that reaches your end goal ( like this video about getting the ball into the cup, but you could come up with lots of other endpoints!). Along the way, you and your child get a lot of time to learn about momentum, velocity, friction, energy transfer, and interference (e.g., the cat).
17. Melting
This is a simple and fun experiment that can be set up in a short time and then fill-up your day with observations and new experiments. Using only things you already have at home, you can set-up an engaging experiment with your kids!
Ice melts at different rates depending on a variety of factors including temperature, pressure, and if there are impurities (think salt, sugar, dirt) in the ice or touching the ice. There is a lot of opportunities to get creative and do the experiment in multiple ways, keeping your kids engaged and developing their investigative, experimental, and critical thinking skills.
- Which ice melts the fastest, slowest, and if they have any guesses about why?
- What other ice-melting experiments they think would be fun: Using different temperature liquids? Using different amounts of ice? Different sized cups?
- Lots of ice
- Several matching cups (i.e., they are the same size, shape, and color)
- Measuring cups
- A variety of liquids for the test
- Paper for writing down observations
- Measure the same amount of ice and place it in each cup.
- M easure equal amounts of each liquid and place them in the cups: try to complete this part quickly so that the ice in each cup is in liquid for as close the same amount of time as possible.
- Set up your cups in a place that is easy for your child to watch and observe.
- Ask them to check in at regular intervals (every 15 minutes, every hour) and record or talk to you about their observations.
Other potential experimental examples:
- Using different liquids to test if they affect melting time;
- Using the same liquid and placing ice in different locations to test what conditions throughout your home affect melting;
- Test if different amounts of ice melt at different rates;
- Test if different kinds of cups change melting time.
There are endless possibilities for you to come up with new ways to complete these simple experiments. You get the idea. Explore more!
18. Breathing Leaves
Science experiments don’t get much more simple than this one! It’s effective though and kids will enjoy watching their leaf ‘breathe’. Learning about plant science is often tricky because it can seem a bit abstract. This experiment allows kids to see the process of plants making oxygen right before their eyes!
A question to ask beforehand:
- What do you think will happen if we leave it for a few hours?
- A fresh leaf from a tree
- A bowl of water
- Pluck a fresh leaf from a tree and place it in a bowl of water.
- Use a rock to weigh it down and leave the experiment out in the sun.
- Have your kids predict what they think they will see when they come back in a few hours (they can write their prediction down or draw a diagram if that’s more their style).
- After a few hours, your kids will see lots of tiny little bubbles on the edge of the leaf and in the glass bowl of water (use a magnifying glass to get a closer look if you have one).
So, what’s happening here? Leaves take in carbon dioxide and convert it to oxygen during photosynthesis. The bubbles you can see are the leaf releasing the oxygen it’s created. You could explain to your kids how trees and plants make the oxygen we need to breathe. Kids Fun Science explains this experiment in more detail and suggests taking it further by leaving the plant for a longer period of time (do you see more or fewer bubbles?) or placing a leaf in a dark area to see what difference that makes!
19. How Does Sunscreen Work?
If there’s one thing I know, it’s that kids hate wearing sunscreen! Trying to get it on them is like wrestling a crocodile. Maybe if they knew how sunscreen worked they’d understand how important it is to wear it when they’re out in the sun (and be slightly more cooperative when we’re lathering it over their little faces). This is a simple experiment that shows kids the difference wearing sunscreen will make to their skin.
- What do they observe when they come back?
- Why do they think one side faded and the other not?
- A piece of colored cardboard (a dark color would be best)
- Your usual bottle of sunscreen
- Have your kids smear the sunscreen over one part of the cardboard and leave the other part clear.
- Kids can then predict what they think will happen when they return to the experiment after a few hours.
- Talk to them about how the sun’s UV radiation is absorbed by the sunscreen so it can’t get through to damage the cardboard.
You could even take it further by trying different kinds of sunscreen or leaving your cardboard out during different times of the day.
20. Make A Rubber Egg
Imagine a world in which eggs can be used like bouncy balls. Well, with a couple of home supplies and a little bit of science, you can live in that world. Your child will be dazzled as they remove eggshells from eggs while leaving the insides intact.
- Is vinegar an acid or a base?
- Is there another substance that could do this?
- Simply leave the egg in the vinegar for a few hours and wait to see what happens. Because of the transformative nature of this experiment, it lends itself to science journaling.
- Consider having your kiddos draw before and after pictures of the eggs in order to track their journeys.
21. Flying Tea Bags
Nothing will get your kids’ attention faster than telling them that you are going to spend some time creating something that will fly. However, because this experiment will involve fire, please ensure that you select a time in which you will be able to provide ample adult supervision.
- How do we stay safe with fire?
- How do we make sure we don’t damage the surface we are working on?
- Why do you think the tea bag will fly?
- Single Serving Tea Bags
- A Small Bowl
- A Non-Flammable Work Surface
- First, open the tea bags and unfold them.
- Empty the leaves from the bag.
- Stand the tea bags up on your surface and light the top of each bag on fire.
As they begin to burn, they will float into the sky!
22. Make Wax Paper Lanterns
Your children will love the chance to display their fantastic art skills by creating these paper lanterns. If you want to add a culture lesson, have your children research German’s St. Martin’s Day and learn about why children parade through the streets with lanterns. We promise there’s a good moral story involved here!
- When could we use lanterns?
- What safety considerations do we need to use in this project?
- Why can we see the light through the wax paper?
- Popsicle Sticks
- To begin, tear a ten-inch piece of wax paper off of the roll and cut it in half.
- After that, fold each piece in half.
- Allow your child to color their image on top of the wax paper. (This is a great place for an impromptu lesson in color mixing).
- Fold the wax paper and iron it (consider something in between the crayon mess and the iron you use on your clothes).
- Finally, glue the craft sticks into squares, add the wax paper, and turn it into a cube.
Voila, you’ve created your own lantern!
23. Create an Insect Habitat
Alright, this one isn’t for the faint of heart. Draw up your courage and send your child into the backyard to collect all of the creepy crawlies they’d like to.
Now you have a home for them. Better yet, you can keep your child entertained for hours as they track the growth of their bug friends.
- What do bugs need to survive?
- What do bugs eat?
- What is the difference between a need and a want?
- Imagination
- Find something that you’re willing to sacrifice to the bugs in order to create a habitat for them – we recommend a shadowbox so that your child can see inside, but a cardboard box will do just fine as well.
- Ensure that there is breathing room for the bugs.
- Create a habitat with sticks, bark, small rocks, dried leaves, and whatever else you can find.
- If you’re willing to hang onto the habitat long enough, use it as an opportunity to talk about decomposition as the bugs begin to break down the twigs.
Long-Term Science Experiments at Home
24. crystal kingdom.
This is the oldest trick in the book, but it’s popular because it’s so effective, fun, and has great results. The only drawback to most crystal-growing recipes is that they take ages to grow, and to be quite honest this one is no exception. In fact, these crystals will take several days to grow but the end result is worth it. The reason is that this experiment involves growing a whole landscape of beautifully colored salt and bluing crystals. Here’s a video for visual reference:
A few things to keep in mind: Allow for plenty of air circulation, preferably inside rather than outside. Ammonia is not necessary but does help in the process.
- What will happen when you add ammonia?
- Why does more salt and less liquid create faster crystallization?
- What part does the bluing solution have in crystal growing?
(Answers can be found here )
- Two bottles of bluing solution
- Large tray/cookie sheets with sides
- Measuring cup
- Liquid watercolors
- Eye droppers
- Cut sponges into large pieces. Spread them out on the tray.
- Measure out 1 cup of each of salt, water, and bluing and then gently mix together.
- Evenly coat or sprinkle the mix over the sponges.
- Add 1 cup of ammonia to the sponges.
- Coat an extra 1 cup of salt on to the sponges.
- By now you’ll see some crystals growing . Sprinkle the magic mix again: 1 cup each of salt, water, and bluing. You can pour the ingredients onto the tray instead of on top of the crystals to keep them from breaking. Don’t worry, more will grow!
- Take an eyedropper, and drop a tablespoon of each liquid watercolor (undiluted) in different patterns over the sponges and crystals.
- Take note of your garden and what the crystal formations look like. You can make a sketch in your notebook as a before and after. Ask questions and observe!
- Observe how the crystals are bigger than before, and notice the colors aren’t as vibrant. Compare the differences in shapes, sizes, and colors.
- If you want more crystals to grow, add a little more water, bluing, and salt.
25. Blow up a Balloon with Yeast
We are surrounded by science in action, but sometimes it is really difficult to see what is happening, especially when it is on a small-scale. When we make bread, yeast ‘eats’ the sugars in the food and creates CO2, giving bread its airy texture. This experiment lets you both visualize what happens when yeast consumes sugar and is a great set-up for an experiment that can be observed throughout the day.
Depending on your supplies and time, you could start with a demonstration and use that to think of other tests, or you could set up several parallel tests at the same time.
- How quickly does the balloon filled with air?
- When does it stop filling (at some point the yeast will run out of food and will stop making gas)?
- Does the starting temperature affect the experiment?
- Does the balloon fill faster in different places in your home (try especially for different air-temperatures, you could include an outside location)?
- Some balloons
- Blow up the balloon a few times before starting so that it’s loosened up a bit.
- Fill the bottle with about 1 inch of warm water (heat is required to activate the yeast, but you could experiment with different temperatures), add the yeast and swirl to dissolve.
- Add the sugar and swirl more.
- Place the balloon over the opening to the bottle and wait. You should expect to see the balloon begin to inflate after around 20 minutes.
- Continue checking and observing how much the balloon inflates throughout the day.
More example experimental setups include:
- Do different temperatures – either with the water you start with or the air the yeast lives in – affect how quickly the balloon blows-up?
- Does using 2x the yeast result in a balloon that is 2x bigger, or blows-up 2x faster?
- Do different types of sugar (e.g., white sugar, honey, syrup, flour) affect how quickly the balloon blows up or how big it gets?
A sk your child to think of new experiments (you could prompt with some of the examples above, or ideas from this post ).
26. Seed Germination
A really simple but fun multi-day experiment is germinating seeds under different conditions. This means finding some quick-sprouting seeds such as beans and putting them in different conditions to see how that affects germination (sprouting leaves and roots) and growth.
I love using seed experiments because they are inexpensive, simple, and leave a ton of room for creating your own unique experiment.
- Which seed will sprout fastest?
- Seeds (Beans, radishes, squashes, and many flowers sprout quickly from large seeds, making them good choices.)
- Small pots or paper cups
- Potting soil
- Cloth or paper towel
- Somewhere with good light
- To get started, you’ll need some seeds – feel free to choose something you already have, if you’re a gardener you might have some seeds ready for the coming season and could spare a few – or find something online or at your local nursery.
- Use small pots or paper cups and fill each with your growth material (we recommend a minimum of 3 for a useful comparison).
- Fill one with potting soil, one with sand, and one with a cloth or paper towel.
- Place them somewhere with good light, and add water.
- Ask your child to predict which seed will sprout fastest, and make observations every day. If possible, make them around the same time each day.
- Once you see growth, you can ask your child what they think caused any differences, and you can use that as a jumping-off point for more experiments
Additionally, you could:
- Use one type of seed and different types of growth media: soil, paper towel, gravel, sand, water, etc.
- You could use different seeds (beans, flowers, grass, herbs) and grow them under the same conditions (soil, water, sun exposure) to see how different plants grow differently.
- You could see how different light conditions (by a window, in the basement, in a bright room away from a window, etc.) affect germination.
You could also extend each experiment by simply continuing to grow each seed to learn whether the different germination time affects long-term growth (you may want to re-pot everything in the soil for this to be effective, depending on the specifics of your initial experiment).
27. Colored Celery
It’s hard to imagine plants having little capillaries inside them that transport water and nutrients, but this experiment shows that in action. It’s easy to set up, but you’ll have to wait at least a day to see some results. Your kids will be able to see how transpiration takes place and plants absorb water from the soil all the way up into their leaves.
- A few stalks of celery (celery works best for this because it’s a bit more visible, but you could also use flower stems)
- Different food coloring
- Place each stalk in a cup of colored water and make your predictions about what will happen.
- After a day or so you’ll see the celery leaves becoming the color of the water they’re standing in.
- Have your kids describe their observations (they can write down what they see or draw it if they prefer).
- If you look at the base of the stem you’ll also see tiny little holes that the colored water is traveling through.
When you’re done with the experiment, make sure you snap the celery and look inside – you should be able to see the capillaries in action. For more ideas, Little Bins for Little Hands has got some great hints and tips for this experiment.
28. Moldy Bread
This experiment is an oldie, but a goodie! Kids love looking at disgusting things and this one will certainly come up with the goods. Not only will kids learn about how mold grows, but they might also take on some lessons about the importance of washing their hands!
You might want to check out the results of this experiment at Science Alert before you start to see if your stomach is up to it.
- A few slices of bread
- Some ziplock bags
- Sticky little hands.
- Get a few slices of bread and lay them out on your kitchen bench.
- Have your kids touch one piece of bread with dirty, unwashed hands.
- They can wash their hands with soap and water and touch another slice, then do the same using hand sanitizer.
- Leave one piece of bread untouched.
- Place them all in clear, labeled ziplock bags and predict which one will grow the most mold.
- Leave your bread slices for at least a week (it may take a bit longer, depending on the conditions where you live) and get the kids to record their observations.
You can also try wiping your bread slices on other surfaces to see what moldy results you get (their laptop or tablet is a great place to start)!
29. Sprouting Beans
Give your household a real survivalist feel by beginning an indoor garden. We recommend planting your beans in a clear cup so that your children can be privy to all of the processes during the plant’s journey.
- How does a plant grow?
- What does germination mean?
- What is in season to grow in our area now?
- Unprocessed Beans
- If you’d like your child to see every step of the process, consider placing the beans inside of a damp paper towel inside of a ziplock.
- You can wait, see the germinated seed together, and then plant it inside of a small cup.
- Once inside the cup, watch it grow.
Extend your work by planting various beans and altering the growth conditions in order see what makes your beans grow best!
30. Begin Composting
Begin your “go green” resolutions by teaching your child the value of composting! Best of all, once the science experiment is done, your family will have a recycling process that will last your entire lifetimes.
- Why is composting important?
- How else can our household go green?
- Why do we need a foundation layer for compost?
- Compost Bin
- Organic Material
- First, create a compost bin. You can purchase one or build one out of wood.
- To begin your composting, you’ll need even amounts of brown materials (think shredded paper, dryer lint, etc.) and green materials (think fruit and vegetable waste, lawn clippings, etc.).
- If you’re really feeling fancy, throw some earthworms in there.
For days to come, your family will be able to discuss what can and cannot be broken down by the decomposers inside of the compost bin. Never-ending science!
31. Turn Grapes Into Raisins
Your kids may or may not eat raising – but we can guarantee you, they’ve likely never considered the option of creating their own!
- What other snacks can we make with science?
- Should we ever eat our experiments?
- How does this work?
- For this experiment, you’ll need grapes. (Really, that’s it!)
Leave your grapes somewhere where they will not be disturbed and use this as an opportunity for your children to journal the changes in the grapes from day to day. Believe it or not, this type of sequential journaling is a valuable literacy skill!
32. DIY Science Experiment
The best science experiment your child can engage in is the one they create themselves! Begin brainstorming a list of questions and let the world be their oyster as they plan and carry out their own experiments. Some of our favorite brainstorming questions, from Scholastic’s Science-Fair Project Guide, are listed below:
- What is the effect of toothpaste brand on teeth-cleaning power?
- What brand of trash bag can withstand the most weight before ripping?
- How does the type of material affect how long a shirt takes to dry?

Cup Amplifier
A lesson in: Sound
Slide a mobile phone into this low-tech amplifier and the result will be music to your ears. The audio is deeper, richer, and louder, thanks to the science of sound waves and the natural amplification created by the cone-shaped cups. If the two cups look a bit like the attentive ears of a cat or fox, that’s no coincidence. Animal ears use the same science, but in reverse: they help creatures hear by gathering sound waves and directing them into the ear. For engineers, that’s a design worth copying.
Customize your amplifier to fit any size phone!
Tabs cut all around the hold make it easy to glue the cardboard tube in place.
Cut a slot with a flap to support your phone.
What’s Going On The Cup Amplifier focuses and projects sound waves, in the same way that a cheerleader’s megaphone (or even just your cupped hands) amplifies your voice. Once sound waves are created, they want to spread out in all directions. The amplifier directs them from your phone’s speakers into the cardboard cups, where, instead of scattering, they are gathered and channeled in one direction—out the openings.

Bake Hygroscopic Cookies
A Lesson in: Hygroscopy.
This simple science experiment is best when you check in on it the next morning. Bake up a batch of cookies, then place them in an airtight container with a piece of fresh bread. Watch as the cookies stay straight-from-the-oven soft thanks to the moisture of the bread (The sugar in the cookies is hygroscopic, which means it absorbs water molecules out of the bread). The best part? Getting to eat the cookies!
The Juice-Tasting Challenge
A lesson in : Taste buds and olfactory senses.
Tummy’s rumbling–it’s time to eat! Did you know that you “eat” with your nose and eyes as well as your mouth? It’s true. Put your family’s sense of smell and sight to the test with this juice-guessing game.
You’ll Need: Masking tape 4 glasses Pen and paper 4 flavors of juice 4 food colorings
How to: 1. Stack a piece of tape on the bottom of each glass and number them one to four, making sure your partner can’t see the numbers. Pour one type of juice into each glass.
2. Send your partner out of the room. Drip a different food coloring into each juice and stir so your partner can’t recognize the juice by its color alone. Record the number, juice type, and color in each glass on a piece of paper.
3. Call your partner back. Tell her to hold her nose, sip from each glass, and guess the juice If she’s like most people, she’ll be kind of confused–her eyes and tongue give her two conflicting flavor messages.
4. Ask her to unplug her nose, close her eyes, and sniff the juice before drinking it. Her guesses should be on target now. All hail the mighty schnoz!

Dry Ice Bubbles
A lesson in: Gas.
Dry ice is already cool enough on its own, but it takes science to turn them into bubbles. When you add water, it changes the temperature of the dry ice, causing the ice to go from solid to gas. That’s where the fog and bubbles come from! Head to Simply Modern Mom to get the full tutorial. But be careful: Dry ice can cause serious skin burns, so make sure your kids are well-supervised and know not to touch the ice.
Messiness factor: Three sponges.
Invisible Licorice
A lesson in : Light and perspective.
Did the candy melt or disappear? Your sweetums might think it’s magic, but it’s really all about how oil redirects light, causing half the candy to disappear! Click here for the instructions on how to recreate this mind-warping experiment.
Egg in a Bottle
Your whistler has the basics of air pressure down just by using their mouth to blow. And now you can amaze them with this science experiment for kids. There is a little fire play involved (dropping a lit paper into the bottle), but that’s what causes the unbalanced air pressure, which pushes the egg into the bottle. Want to test it out? Head over to Steve Spangler Science for the tutorial.
Invisible Ink
A lesson in: Oxidation.
If your snacker has noticed how their apples have turned brown after being left out for too long, then they’ve seen oxidization in action (loss of electrons and nutrients when in contact with oxygen). Fortunately, lemon juice only oxidizes when in contact with heat. This method works with baking soda and milk too. Click here to find out how to write secret messages with your little spy.
Kid-Safe Lava Lamps
A lesson in: Density and intermolecular polarity.
These sound like big words for our little ones, but there’s an easier way to break it down. Water and oil won’t mix because they’re not the same “weight” or substance (just like clay and LEGOs won’t become one). Now add a drop of food coloring (which is heavier than oil) and a fizzy tablet and watch the air bubbles take coloring with them to the top. Head on over to S. L. Smith’s blog to see how it’s done .
Messiness factor: Two sponges.
A Lesson in: Crystallization.
Be careful: The water only has the power to make the sugar crystals “invisible” when it’s piping hot. After the water cools down and evaporates, the sugar turns back into a solid. And with a little help of your sugar-soaked string, the crystals will find a home to grow upon and become rock candy. Learn how to make your smart sweets with these instructions from the Exploratorium .
S'more Solar Oven
A lesson in: Solar power.
Harness the power of the sun to make your favorite campfire treat! With just a few common household items you can create an eco-friendly oven just for melting marshmallows and chocolate, plus you can teach kids about the power of the sun. Click here to learn how.
Homemade Slime
A lesson in: Polymers.
Is it a liquid or solid? The answer is both! This DIY slime—made from glue, borax, and water—is also known as a polymer (molecules that can stick close together to be a solid or spread apart and take liquid form). And it’s all thanks to borax, which acts as a binder to prevent the glue from going completely liquid. Check out Explorable’s recipe for mixing the ingredients . Prolong the life of your goo by keeping it in an airtight container in the fridge. And, if you need help with cleanup, check out our guide for how to get slime out of clothes, couches, and hair .
Make Fizzy Lemonade
Plain old fresh-squeezed lemonade is so last year. Boost the fun quotient and learn a simple science concept simultaneously when you recreate this edible Fizzy Lemonade drink from Learn With Play at Home . It’s super easy to mix and little sippers report it’s pretty tickly too. A great alternative to the baking soda-vinegar volcano, it shows kids what happens when an acid and base are mixed together.
Whirlpool in a Bottle
A lesson in: physics, weather science.
This easy little experiment doesn't take much: just two empty and clear 2-liter bottles, a metal washer, water and duct tape. Food coloring is optional. Fill one bottle with about two-thirds water. Place the washer on the bottle and line up the empty bottle on top of the water-filled one. Wrap the duct tape around the middle securing the two bottles together. Then, turn the bottles upside down. Does the water go straight down or do you see a mini whirlpool (Swirl the top or bottom a bit for a better effect.)? The spinning water is called a vortex, and all tornadoes, hurricanes and typhoons are examples of air vortexes. Since you’re using water, this is an example of a whirlpool. As the water spins faster, it pushes to the outside of the bottle creating a hole in the middle. The air from the bottom of the bottle comes up the middle and the water from the top flows back down through the hole.
Messiness factor : Two sponges.
Salt Crystal Feathers
A lesson in: Evaporation
You’ve probably tried a salt crystal growing kit at some point in your life (5th grade Science Fair perhaps?) but Schooling a Monkey takes the idea to a new level with these Salt Crystal Feathers. This awe-inspiring project is deceptively simple and inexpensive to achieve, and requires just a wee bit of patience to see the results—kids will love checking in on the progress.
Soda Blasting Experiment
A lesson in: Chemistry, pressure, and release of pressure
This experiment is one you'll definitely want to do outside. Step it up with this Mentos + soda experiment: head to Steve Spangler for all the need-to-know details on this engaging experiment.
Messiness factor: Three (very epic) sponges
Melting Rates
A lesson in: Solar science and absorption
Different colors have different heat-absorbing capacities. Black has the greatest heat-absorbing capacity, which results in ice melting quicker than white, which reflects the most light. Learn how to observe and report on which colors affect ice’s melting rates here on Curiodyssey. Get more sidewalk science ideas here .
Make Elephant Toothpaste
A lesson in: Chemistry and the exothermic process <<<impress your kids!
If you’ve ever wondered how elephants keep their tusks clean, we’ve got the answer. They use elephant toothpaste! Find out how to mix your own and figure out the science behind this dynamic exothermic (heat-releasing) reaction from Fun at Home With Kids . Our favorite part? That you get to throw in some sensory playtime after the action’s over.
Messiness factor: Three sponges. Maybe four.
Bending Water with a Comb
A lesson in: Electrical currents and static electricity
This static electricity science experiment couldn't be any easier. In fact, other than a balloon or going down the slide, it might be the easiest way to teach kids about electrical currents. And, you can impress them with your wizarding skills once before you reveal the science behind it. Click here to get the step-by-step.
Regrow Leftovers
A lesson in : Photosynthesis and plant science.
Insert a little plant science into the mix by re-growing food from scraps. Think onions, potatoes, and lettuce for this one ( psst… green onions are a super easy, fast option). Get the low down on all that recycled goodness at Mrs. Happy Homemaker . Since plants need water and sunlight to grow, exposing scrap roots to that winning combo helps them recharge.
Messiness factor: Two sponges.
Turning Pennies Green
A lesson in: Chemical reactions.
It happens to the Statue of Liberty and it happens to the change in your pocket! Create your own home lab with just a few household ingredients (this experiment will literally cost you just pennies). It’s also a chemical reaction with very non-toxic ingredients, so it’s safe and fascinating even for young kids. Click over to Buggy and Buddy to get the simple how-to.
Film Canister Rocket
A lesson in: Rocket science.
Like the popular baking soda and vinegar experiments, this film canister rocket literally takes it to the next level by using that creation of gas and energy to jet off into the sky. If your explorer has seen videos of mountain tops getting blown off during a volcanic eruption, this science project is pretty much any space lover’s version. Get the building instructions over at The Science Kiddo .
Disappearing Egg Shell
Can you and the kiddos solve the mysterious case of the disappearing eggshell? Following the simple how-to at Go Science Kids , you’ll learn the step-by-step and talking points about the process along the way. Warning! Although it’s totally non-toxic, toddler-aged kids will be tempted to squeeze the egg at the end so make sure it’s a supervised experiment. Visit Go Science Kids to get cracking!
Fishing for Ice
A lesson in: Freezing/temperature.
Children living in snow-covered cities might witness their neighbors salting the driveway. Well, while that is definitely not for fun, this experiment is. Salt lowers the freezing point of ice so it melts, but it won’t be able to freeze unless it’s cold enough. See how The Science Kiddo made a clever game with this knowledge.
A lesson in: How clouds hold water.
Let your imagineers pretend shaving cream is a cloud that holds colorful raindrops. As they squeeze more and more food coloring, their “cloud” will soon release the excess below—just like how real clouds get too heavy and let the rain loose on a gloomy day. Learn how to re-create this weather experiment here .
Dyed Plants
A lesson in: Capillary action.
Find out how plants “drink” water with some food coloring . Use carnations, roses, or stalks of celery submerged in the colored water and watch the liquid slowly seep through the plant’s “veins” and towards the leaves. Keep an eye out -- you could have a very colorful bouquet just after the first day. Get the rundown by Dad’s Book of Awesome Science Experiments over here .
Dancing Oobleck
A lesson in: Sound waves.
The word “oobleck” comes from a Dr. Seuss story where a young boy must rescue his kingdom from a sticky substance. But the neat part of this experiment is how oobleck reacts to vibrations. Put the oobleck over a subwoofer (on top of a cookie sheet!) and watch it dance to different frequencies. Your dancer will see how sound isn’t just about volume! Check out more of this awesome experiment from Tammy of Housing a Forest .
Messiness factor: Five sponges.
Homemade Lightning
A lesson in: Static electricity. (Or weather science.)
Lightning is essentially electrons moving uber fast between the sky and the earth—and with a few simple materials, you can use homemade static electricity (the reason behind your hair sticking up when you rub a balloon or go through a tunnel slide super fast) for DIY lightning. Figure out how to recreate a family-friendly version of this spark by visiting the activity blog Learn Play Imagine .
Make a Bug Vacuum
A Lesson in: Entomology
Scientists capture bugs for study using a mouth-powered vacuum, called an aspirator or a pooter. Kids can make their own version from a mason jar, then use it to gather ants (or other small insects) and observe them in action.
What you'll need: Pint-size mason jar with a two-piece lid Milk or juice carton Hole punch 2 bendy straws Tape Gauze pad
How to: 1. Open the milk carton along the seams and flatten it out. Use the inner lid of the mason jar as a template to trace a circle on the carton. Cut out the circle and punch two holes in the center about an inch apart.
2. Carefully slide the short ends of the bendy straws into the holes. Tape a piece of gauze pad around the end of one straw to prevent any bugs from getting sucked up.
3 Set the lid on the jar and fasten it in place with the ring.
4. To use your pooter, place the tip of the straw without the gauze near a bug. Put your mouth on the straw with the gauze, and gently suck in. The bug should travel up the straw and land unharmed at the bottom of the jar.
Take It Further Capture some ants in your bug vacuum, then use a magnifying glass to observe these remarkable insects up close. Open the jar and feed them a few drops of sugary water or corn syrup, or try giving them some birdseed. Ants live in colonies headed by a queen ant, and they can’t last long on their own. When you are done observing them, release your ants where you found them. (Note: Some ants bite, so be careful handling them.)
Tell Me More Ants were the Earth’s first farmers. For millions of years, certain species have been creating underground gardens where they grow their favorite fungus for food. They tend to their crops, bringing them water and even weeding out other fungi they don’t want.

A Smell Challenge
A Lesson in: Olfactory senses.
Teach kids the importance of smell with this activity that asks them to use only their noses to identify objects. Can they sniff out the fish oil over the garlic cloves? The lemon juice over the orange oil? Homeschooling blogger Ana has the instructions at Babble Dabble Do .
Is This Soluble?
A Lesson in: Mixtures
Teaching children chemistry can become a fun, at-home activity as a weekend afternoon project or as part of their remote learning curriculum. One of the best experiments you can do is the mixing activity. With this exercise, children will learn the difference between soluble and insoluble substances. Do not worry! You can do it with ingredients you already have in your kitchen!
Ingredients
- Oil (cooking oil, vegetable oil, olive oil, etc.)
- Food Coloring
- Transparent containers with a lid or transparent cups with a spoon to mix
Before you begin the activity, ask the children what each ingredient is—whether it is a solid, liquid, or gas—and what they think will happen when you begin mixing them. This guarantees a hands-on experiment that will allow the children to feel they are in control.
- Mix the water and the sand. Children will notice there is a separation between both ingredients and that layers have formed, so it is an insoluble reaction.
- Mix the water and the food coloring. Children will see them combine—the water turning into that color—and know it is a soluble reaction.
- Mix the water and the table salt. The salt will disappear in the water, making it another soluble reaction.
- Mix the water and the oil. This time, a clear layer will be formed, showing another insoluble reaction.
After these mixing activities, you can further this experiment by letting the children find other ingredients to mix with water and have them determine if that substance is soluble or insoluble. The main goal is to show them different reactions and layers.
For a clear example of this experiment, check out this video .

7 Budget Friendly Science Experiments
These science activities and projects will get your kids excited about learning science. Here are 7 Homeschool Science Experiments to do on a budget!
Raise your hand if your kids love science experiments.
We LOVE them around here, but they can be super costly! They are such a fun way to learn though – and I have two kids that learn best by doing (and not so much sitting in a confined area).
Budget Friendly Science Experiments
Last fall I searched high and low for experiments that will work well with our budget. We did these experiments over the course of the last twelve months, incorporated them into our homeschool lessons and had so much fun!
Check out these 7 budget friendly homeschooling science experiments.
#1: Colorful flowers
Science experiments can be fun. Place white flowers in a vase full of colorful water. Give it about 20 minutes and the flowers will start changing colors. It’s pretty cool to see the flowers change colors.
We used simple colors like red, green, blue and yellow food dye – then allowed the kids to each create their own color by mixing the food dye (purple, orange, etc). Since most plants drink water through their roots, it took anywhere from a few hours up to a full day to see the colors transpose into the white flowers.
So very fun.
#2: Paper Airplane Fun
If you’re on a super budget, but want to teach your kids some valuable science, then you need to do this experiment with them. Create a paper airplane and watch its flight plan go straight. Create another airplane and fold the corner down. And then watch how the airplane doesn’t really fly all too well.
#3: Pop Rocks Fun
Homeschoolers love to have fun, so why not embrace it? Adding Pop Rocks to a bottle of soda is fun enough, but then place a balloon in the opening. The balloon will inflate and your kids will be amazed. This is so budget friendly, but also so fun.
#4: Melted Crayons
How many crayons do you have laying around? Do you have molds you can use? Peel the crayons and place them inside the molds. Place the “oven safe molds” only into the oven and bake at 200 degrees for 10-15 minutes.
You will have a new purpose for your crayons, plus the kids will love watching this transformation.
We used owl molds for our crayons – even the smallest kids helped out by peeling the wrappers off of the crayons while the older kids broke them in half. It almost seemed like “giving” them permission to break crayons made their whole day.
Who knew?!
#5: Freezing Bubbles
Winter is quickly approaching, which means you can do this fun experiment with the kids. This one is super cheap too. Simply take the bubble blowing outside. The bubbles will freeze in the cold weather.
Although we don’t have “winter” snow and cold here in the Phoenix area, we had a great time doing this experiment with the kids up in Minnesota with the cousins last Christmas.
Eleven kids, lots of bubbles, and a morning of excitement completely turned a “boring” snowy day into a fun experiment to see who could make the biggest frozen bubbles.
My kids said “Mom! This is SO cool! Can we move so we can do this every winter?”
… Unfortunately I’d rather shovel “sun” than snow 😆
#6: Grow Mold on Bread
Every homeschooling family needs to do this with their kids ASAP! Growing mold on bread is fun, cheap, and a great way to learn about mold.
Simply put bread in different environment to see how quickly or not quickly mold can grow. Let your kids get creative with where they put their bread.
#7: Static Electricity
Balloons are the perfect partner for doing science experiments on a budget. You can pick up a pack of balloons are the dollar store. Walk around rubbing the balloons on items. Take note of what has the most static.
Schiphile has some great tips on static electricity and provides instructions for studying static electricity and it’s effect on many different materials.

Stretch that science budget!
Teaching science requires a lot of hands-on activities to help students connect to concepts in a experiential way. Take a peek into any science equipment catalog and you can find amazing ways to accomplish this. But the reality is that many elementary classrooms don’t have school budget money to outfit a science lab with the latest cool gizmos and gadgets. Here are some inexpensive science experiments that teach important concepts without breaking the bank.
1. Navigate Newton’s Laws of Force and Motion.
Head to the toy aisle and snap up some cars and a bag of marbles. Then swing by the party aisle for some straws and a package of balloons. Also, make sure you grab a package of bathroom cups and you are ready for three great activities that can be used in an 3rd–6th grade classroom to introduce or extend learning about Newton’s laws of motion.
Newton’s first law can be tackled by making a ramp out of an old game board (Finally! A use for that Candyland game you found at a garage sale last year!). Place a book at the bottom of the ramp to act as the force stopping the car you will place at the top of the ramp. Place a penny on the hood or roof of the car and let the car roll down the ramp. Measure how far the penny continues to travel after the car has stopped. You can change the angle of the ramp and determine if it has any effect on the distance the penny will fly.
For a great activity to demonstrate Newton’s second law, use a book and a ruler to make a ramp. Cut an opening in the side of a bathroom cup and place it at the bottom of the ramp. Roll the two different sizes of marbles down the ramp and measure how far they push the cup.
If you need help teaching Newton’s third law, use the balloons and straws to make rockets. Start by threading a straw onto a length of string or fishing line. Stretch the string across your room and attach each end to a wall. Blow up a balloon and twist the end closed, but don’t tie it. Tape the balloon to the straw and let go. The force of the air pushing out of the balloon will send it zipping down the string.
2. Take a spin to learn about friction.
Friction can be a tricky topic for kids because the only example they can usually come up with is rubbing their hands together. Here are a couple of activities that can help build their understanding of opposing forces and only cost a couple of dollars.
Haul out those old game boards again and cover them with whatever different textures you can find. I use foil, shelf liner, bubble wrap, cardboard, wrapping paper, and a welcome mat. Make a ramp out of heavy paper or cardboard. Prop one end of the ramp on whatever is handy and roll a toy car down it. Measure the distance the car travels on each of the different surfaces.
Grab packages of tops from the party favor section of the store. Have the students choose several surfaces that have different textures like the top of their desk, carpet, tile. Have the students time how long the top will spin on different textured surfaces. You can even head outside and try asphalt, grass, and concrete.

3. Model the phases of the moon.
You can make an inexpensive model that demonstrates the phases of the moon out of ping pong balls and bottle caps. Use an orange or yellow ball to represent the sun. Use a permanent marker to color half of a white ping pong ball black. This will represent the moon. I found some cute doggie balls that were blue and green and use them to represent Earth. Students can see what the moon looks like as it makes a trip around the Earth.
You can also pick up a hula hoop and attach eight moons evenly spaced to it. Students can take turns standing in the hoop while their friends hold it at eye level. By turning in a full circle, the student in the center can see all of the phases.
4. Chase shadows to track the sun’s motion across the sky.
Many students struggle with understanding why the sun changes position and how we see that change. A simple and fun way to help students track the position of the sun during different parts of the day is to trace their shadow using sidewalk chalk. Have the student who is being traced stand in the same exact location several times during a sunny day. Use a different color of chalk each time to trace their shadow. At the end of the day you can have a discussion about the direction their shadow is, the changing length of their shadow and how this relates to the location of the sun during different times of the day.
5. Bounce around to learn about energy.
Dollar stores are a great place to find a variety of balls: foam, rubber, bouncy, hard, soft, squishy, knobby. Pick up several different kinds and have the students design an experiment to test which kind of ball bounces the highest or the most times when dropped from a certain height.
6. Sort all sorts of doo-dads to learn about classification.
Do your students need help understanding classification? Are they ready to try making a dichotomous key on their own? There are plenty of inexpensive choices to be found at any dollar store. Craft supplies like pompoms, foam stickers, bags of buttons, beads of every shape, size and color make a perfect, kid friendly classification starting point.
7. Witness the dance of solar energy.
Look at your local Dollar Store for items that have a solar panel. You can incorporate these items to help kids understand concepts such as light as a form of energy and that light energy can be changed into other forms of energy by solar panels. I found a whole shelf of dancing flowers as well as solar powered calculators.
8. Light up learning around circuits.
Instead of spending lots of money on battery holders, bulb holders, bulbs, and wires with special clips, I headed to the dollar store and picked up a string of Christmas tree lights, a box of foil, and some electrical tape. Add a 9V battery and you have everything you need to make a circuit. Tape a strip of foil to each post on the battery, making sure the the two pieces of foil don’t touch. Then clip every other bulb from the strand and strip about a half inch of the insulation off of the wire and you are ready to create a circuit. Students can even place objects between one wire and the foil to determine if the object is a conductor or insulator.
9. Model your own cave formation.
If your students need to understand how solution caves form, here’s a terrific model they can make using clear plastic cups, modeling clay, and sugar cubes. Place a dozen or so sugar cubes in the bottom of a clear plastic cup. These represent limestone. Top that off with a thin layer of modeling clay to represent the surface. Slowly pour water into the cup. The water will begin to seep through cracks around the edge of the cup and as it collects in the bottom, the sugar cubes will begin to partially dissolve leaving open spaces. Have the students sketch the changes.
10. Use play dough to learn about fossils and the layers of the Earth.
Everybody loves Play Dough. Dollar Stores usually have inexpensive versions. They also usually have tubs or tubes of dinosaur figures. If you can’t find any with the toys, check the party supplies where they may be packaged as a party favor.
Students can roll out different colors of the dough and stack them up to represent the layers of sedimentary rock. You can use their models to discuss which layer is oldest. Provide students with a plastic knife or craft stick and they can make models of movement along fault lines or they could use a plastic spoon to model canyon formation. If you include a dinosaur between two layers, the students can make a model of a cast and mold fossil.
This activity could be extended by burying dinosaurs in plastic bowls full of sand. Stack three bowls inside each other to represent three layers of sedimentary rock. Give your amateur paleontologists a toothbrush and allow them to “dig” up their fossils and determine which one is the oldest and which is the youngest.
