16 Super Cool (And Simple) 1st Grade Science Projects To Do At Home

Categories Activities & Ideas

Science can be a lot of fun for first graders (especially if they’re taking part in experiments that go whizz, pop and bang).

To solidify their scientific learning, and make sure they’ve fully understood the concepts, you can set them the task of completing a science project with their parents.

To avoid a free-for-all, and to take the pressure of the parents, you can provide your class with a selection of projects to choose from.

Below, we’ve listed 16 of the coolest (but simple) 1st grade science projects kids can do at home with their parents.

Get those goggles on and we’ll get to it.

1. Density Tower

A density tower is a simple experiment for first graders to try at home.

Children will need different liquids like honey, dish soap, water, vegetable oil, and rubbing alcohol; a clear, tall glass or plastic container.

The great thing about this experiment is that most of these items will be readily available at home.

Method: Carefully pour each liquid into the container, one at a time.

Start with the densest liquid, like honey, and end with the least dense, like rubbing alcohol.

Students should notice that the liquids form layers.

This experiment helps children understand the concept of density and how some liquids are denser than others.

2. Growing Crystals

Although you can buy kits to grow your own crystals, doing it from scratch is much better fun (and it’s better for the student’s learning).

To grow crystals, they will need salt or sugar, hot water, a jar, a string, and a pencil.

Method: Dissolve as much salt or sugar as you can in hot water until no more will dissolve.

Hang the string into the jar so that it’s not touching the sides or bottom, using the pencil to hold it in place.

After a few days, crystals will begin to grow on the string.

This teaches kids about the process of crystallization and how solids can dissolve in liquids and then reappear when conditions are right.

3. Shadow Tracking

First graders will need a sunny day for this science project. They will also need a toy or object, chalk, and access to a sidewalk.

Method: Place the toy on the pavement and use chalk to trace its shadow in the morning, noon, and afternoon. Observe how the shadow changes.

This helps kids learn about the movement of the Earth in relation to the sun and how it affects shadows.

4. Magnetic Exploration

For this project, children will need a magnet and a collection of small items from around the house.

Method: Children can test which items are magnetic and which are not. They can separate the items into two piles: magnetic and non-magnetic.

This introduces the idea of magnetism and helps children identify which materials are attracted to magnets.

5. Dancing Raisins

This experiment is super fun and only requires clear soda (like Sprite or 7-Up), a clear glass, and raisins.

Method: Fill the glass with soda and drop in a few raisins. Watch as the raisins “dance” up and down in the glass.

The carbonation in the soda attaches to the raisins, making them float to the top. Once the bubbles pop, the raisins sink again, illustrating the concept of buoyancy.

6. Celery and Food Coloring

This experiment will make first graders laugh while also teaching them about plant life.

They’ll need clear glasses, water, food coloring, and celery stalks with leaves. Method: Fill the glasses with water and some drops of different food coloring shades to each glass. Place a celery stalk into each glass. Over a day or two, observe the celery, especially its leaves.

This experiment illustrates capillary action and how plants absorb water and nutrients from the soil.

7. Balloon And Static Electricity

First graders are probably already familiar with the static generated by balloons but this experiment helps them understand a little more.

They will need a balloon and small pieces of paper or lightweight fabric.

Method: Inflate the balloon and tie it off. Rub the balloon on your hair or a piece of wool. Move the balloon close to the pieces of paper or fabric and watch them jump towards the balloon.

8. Homemade Volcano

Kids of all ages LOVE a volcano experiment.

For this one, the first graders will need a small bottle, baking soda, vinegar, dish soap (for a foamy eruption), and food coloring (optional for colored lava).

Method: Place the bottle on a tray or in a container to catch the overflow. Fill the bottle a quarter full with baking soda. Add a few drops of dish soap and food coloring if desired. Pour vinegar into the bottle to start the eruption.

This classic experiment demonstrates a basic acid-base reaction.

9. Ice Melting Race

This fun experiment helps children understand the different properties of substances and how they can affect the state of matter.

They will need ice cubes, plates, and various materials like salt, sugar, and sand.

Method: Place an ice cube on several plates. Sprinkle different materials on each ice cube: salt on one, sugar on another, sand on the next, and leave one as a control with nothing added. Observe which ice cube melts the fastest.

10. DIY Sundial

The DIY sundial experiment is nice and easy and doesn’t require much to do.

All that’s needed is a straight stick (a pencil will do the job), a sunny day, and a piece of paper or a paper plate. Method: Stick the stick through the paper or plate. Every hour, mark the end of the stick’s shadow with a stone or by drawing on the paper. Label each hour as you go.

This project demonstrates how the position of the sun in the sky changes over time and can be used to tell time.

11. Floating Eggs

This is another super easy science project for first graders – and you don’t need many items, so parents will be a fan.

This requires fresh eggs (this part is important), salt, two clear glasses, and water.

Method: Fill both glasses halfway with water. Add a lot of salt to one glass and stir until most of it dissolves. Carefully place an egg in each glass and observe.

This experiment teaches about buoyancy and density. The saltwater is denser than freshwater, which can make the egg float.

12. Homemade Compass

For this science project, first graders and parents will need a needle, a small cork or foam piece, a magnet, and a bowl of water.

Method: Stroke the needle repeatedly in one direction with the magnet. Insert the magnetized needle into the cork or foam and place it on the water in the bowl. The needle should align with the Earth’s magnetic north.

This introduces the idea of Earth’s magnetism and magnetic fields – and most kids find this one pretty awesome.

13. Coffee Filter Chromatography

This project demonstrates how different colors can be combined to create other colors and introduces the concept of chromatography. It allows first graders to be a little creative.

To do this task, they will need non-permanent markers, coffee filters, and cups of water.

Method: Draw a dot or a line with the marker in the center of the coffee filter. Fold the filter so the center is at the bottom and dip it into a cup of water (ensuring the dot/line doesn’t touch the water). Watch as the water rises and separates the ink colors.

14. Pepper And Soap Trick

This is a pretty cool science experiment which will amaze little ones.

It requires ground pepper, dish soap, and a bowl of water. Method: Sprinkle some pepper on the surface of the water. Then, dip a fingertip into dish soap and touch the water’s surface. The pepper will rapidly move to the sides of the bowl.

This illustrates the concept of surface tension in liquids.

15. Germination Station

Demonstrating germination isn’t an instant results science project, but it’s a useful one to try with first graders – they can return to inspect the experiment every day for the first signs of sprouting.

To do this at home, they will need bean seeds, paper towels, a clear plastic bag, and water.

Method: Moisten the paper towel with water and place a few bean seeds on it. Fold the paper towel gently around the seeds and place it in the plastic bag. Seal the bag and fix it to a window with strong tape. In a few days, observe the seeds sprouting.

16. Solid, Liquid, Gas With Chocolate

This tasty science experiment will show first graders solid, liquid and gas – the three primary states of matter.

Kids and their parents will need chocolate pieces, a pan, and a freezer.

Method: Show the solid chocolate piece. Melt it in a pan to show its liquid form. As it cools, steam or vapor may be seen, representing the gas state. Finally, you can place the melted chocolate in the freezer to revert it to its solid state.

These science projects can easily be done by first graders at home with their parents.

Most of these experiments don’t require many items, and kids will have a lot of fun with them.

33 Engaging & Inspiring 1st Grade Science Projects

There are a lot of 1st grade science projects that can help children draw conclusions and make connections to the world around them. In first grade science, children learn about topics within life, physical, and earth sciences. That means there are a lot of different types of science experiments to choose from when looking for an engaging (or easy) project for your class or at home.

Table of Contents

What science topics do 1st graders learn, the best 1st grade science experiments, what are some easy science projects, check out these additional 1st grade resources.

Through the life sciences, first graders learn about the characteristics that differentiate living and nonliving things. They learn about animals and how they adapt to and interact with their surroundings. 

Children at this age also learn about the seasons, weather patterns, and the water cycle through the earth sciences, along with the phases of the moon. 

First graders are also introduced to the basic concepts of motion and forces where they explore how objects move, and they manipulate variables so they can compare cause and effect . Students this age learn how to ask a question that can be answered through investigation and observation. So a good science experiment that supports these topics starts with a testable question that children will be able to answer at the conclusion of the investigation.

In partnership with Teach Simple , whose marketplace is full of educational materials created by actual teachers (plus 50% of all revenues go to them), I’ve gathered 33 great kid-friendly science projects that your first grader will enjoy in the classroom or to pass the time by at home. Have a look! 

The projects in the list below address the topics I mentioned above that 1st graders learn in school. Allow your child to take the time to manipulate variables and make observations and discuss them with you during the experiments so they can also learn how to draw conclusions. 

• Make A Rainbow From Children’s Museum

First graders love to learn about rainbows. This experiment shows how white light is a combination of all the colors of the rainbow. When you shine the flashlight on the glass of water, the light waves are refracted, or bent, causing the light to break into its various colors. 

Supplies you’ll need:

• Clear glass
• Darkened room

If you’re looking for a bit more to hit this concept home, try out Teach Simple’s Colors Science, Literacy and Math Activity by KP Classroom, which provides companion activities to support this experiment.

Science Day: 32 Science Experiments and STEM Activities for Kindergarten and First Grade

Science Day  is perfect for busy kindergarten and 1st grade teachers who need a fun and easy way to incorporate science and STEM each week. 

Providing young students with these hands-on experiences is fun for everyone and helps build thinking, science, and writing skills.

There are 32 activities for students to explore, observe, investigate, experiment, and design! 

Let’s take a closer look!

What's included?

• 32 activities with directions and photos
• Recording sheet options (differentiated based on students’ readiness levels)
• Pacing suggestions
• Skill and content lists

Do I need complicated materials?

No! Most materials needed for the activities are basic and commonly found in schools, at home, or in a local store. Check out the list of items.

What activities are included?

Let’s take a closer look at some of the 32 activities you’ll find in  Science Day . 

Dive into the depths of science with our sink-or-float STEM.

Students explore sinking and floating by designing boats that will float in water using only aluminum and some things that will weigh down to try and make it float!

Your students will enjoy the engineering aspect of problem-solving!

Do you ever wish your apple wouldn’t brown so fast after you slice it?

In scientific terms, it’s due to an oxidation process. Lean into making predictions and observations with your students about which liquid they think will keep the apple from turning brown.

Through observations, your little scientists will see how well they predicted!

Rev your engines and race to the finish line with our ramp-racing cars!

Your students will enjoy predicting whether a tall or short ramp will cause a racecar to go the farthest distance.

Little will your students know that they are laying the foundation of force and motion concepts!

Your students will be BLOWN away with excitement discovering whether certain objects will blow away using a straw!

Have students predict if they think the objects will move, and have them test out their investigation with a little breeze.

See if they can figure out what the objects that got blown have in common to analyze their results.

There will be some bear-y excited students when discovering the needs of bears.

Your students will engage with making an edible habitat that will support the life of a brown bear. 

Students can also write a sentence with what brown bears need on their own or through a class chart. Finish off by enjoying a tasty snack!

Let’s roll in and A-MAZE your students with force and motion!

Your engineers will be tasked with designing a marble run that will change the direction of the marble as it moves.

This a great time to emphasize the importance of teamwork and a growth mindset as they test out their designs and have to redesign as needed.

Pass the energy, please!

Your students will discuss how energy helps animals stay alive, grow, and move. 

Using paper chain models, your students will practice their fine motor skills by creating a paper chain showing the energy flow from the sun to the organisms.

Be the lucky charm of the day with a magical science reaction!

What if you could add a little spark to vinegar and baking soda? Your students will predict what will happen when you mix yellow vinegar and blue baking soda. 

This is a great way to see if they can apply their art knowledge of primary colors coming together to make a secondary color!

Explore the wonder of clouds with our little eyes!

Take your students outdoors using a cloud viewer to discuss the movement of clouds and the different types of clouds. 

Your students can sketch drawings and write about how clouds change through observations. Follow up with a class discussion of their observations and what cloud changes mean.

Create shade for man’s best friend!

With various scrap materials, your class will work in teams to design a shade structure to protect their dog figurine from getting too hot from the sun using some parameters.

Students create a plan, improve their ideas, and test their creations in class before going outdoors to see them in action.

What a fun way to bring out engineering practices and creativity!

Get started!

An experiment a week….all year long!

Light & Sound Activities & Lesson Plans for First Grade

Teaching Science has definitely  not been my favorite subject to teach…even in first grade! It always seemed so challenging to explain such difficult concepts to kids! I’m hopeful these ideas for teaching light & sound worksheets and activities will be as helpful for you as they were for me. 👇

I’m not gonna lie…I often pushed Science off in my plan book because I wouldn’t want to face the questions from first graders {lame, I know!} When my school district decided to move over to the Next Generation Science Standards, I knew I had to get ahead of this curve and dive in deep. I set out to create easy to understand and do science lessons!

I am SO excited for my first unit in the 1st Grade Standards, Sound & Light ! You guys, this labor of love was created so that ALL of us can easily teach the NGSS and actually understand it!

This unit is chock-full of step-by-step lessons, experiments, anchor charts, book suggestions, YouTube videos , response sheets and more to make sure your students understand Sound & Light through hands-on experiments and investigations.

Each lesson includes a learning target, background information, talking points, a book suggestion, and

Background Info for the Teacher & Prepping for Lessons

When I taught from our Science curriculum, I was always so overwhelmed by how much background info was provided! Was I going to be tested at the end? Eeeek!

In this Sound & Light Investigations unit  I’ve shared  just the right   amount of information to totally “get” what you’re teaching! There are also easy-to-understand vocabulary posters to help your students understand these big ideas!

Each of the investigations uses super simple materials that you have around your classroom or can easily get from parents.  I’ve included a Materials List to make gathering these goodies easy!

I’ve also included a Family Letter to inform your students’ families about what they’re learning about!

What is a Scientist? Activity

Kick off the unit by chatting about what being a scientist actually means!

Kids L•O•V•E science! Get them thinking about just what a Scientist does! It’s fun to gauge their thinking and start meaningful conversations about science.  The bonus is that your students will start to see themselves as scientists!

I had SO much fun doing these experiments when I was making this unit, so I am certain you will, too! The best part – your students will  definitely have fun and learn about light & sound along the way!

Sound Activities & Lesson Plan Ideas for 1st Grade

You’ll start this set of sound explorations by taking your kiddos outside for a sound hunt.  Give them a while to explore and record the sounds they hear using their senses.  They’ll fill out a mini book and add their sounds to a poster.

Once your students have an awareness that sound is  everywhere , you’ll move into lessons to get them making sounds and understanding sound waves.

This kazoo is SURE to be a hit in that exploration!

In the following lessons, students will continue to explore how sound moves and how they can change the sound things make.  Simple supplies from around your classroom will give students a chance to make their very own instruments!

Thankfully I had this cutie to help me test out this hanger instrument! This lesson helps students see how sound moves through different materials.

The final lesson in the sound exploration gives students a chance to see how sound moves through solids, liquids & gases.

By the end of these experiments, students will have a good understanding of sound! I’ve included book suggestions, YouTube links, and additional ways to extend the lessons!

Light Activities & Lesson Plans for 1st Grade

Here’s a peek at all the lessons for sound.

To start, your students will explore why light is needed! Without light, we can’t see anything!

Then, you’ll move into a discussion about Natural vs. Artificial light.

The students will follow up the discussion with this PowerPoint game.  Check out a sneak peek below!

After understanding that light is necessary to see and that there are various ways to see light, you’ll move into a bit meatier ideas.  In the next lesson, kids will investigate different materials to see how light reacts.

Grab some cheap flashlights from the dollar store and a few different cups and you’re all set to go!

Through exploration, the students will see that light affects transparent, opaque, and translucent materials differently!

By far, my favorite lesson is #4 – Eye Tricks!

Students will do a light experiment to see just how refraction works! I bet this will be a crowd pleaser in your classroom!

Check it out in action!

Have you ever met a kid who  doesn’t love a mirror? Well, turn that fun and curiosity into some learning with these explorations. 

Students will explore with mirrors, toys, and lights to see what happens with light!

To wrap up your light study, you’ll give students a chance to head outside and explore shadows!

Lesson Ideas to Better Understand Sound & Light

To show their learning, students will wrap up the unit combining their knowledge of sound and light!

First up, they’ll create a telephone using string and cups. Don’t you remember doing this when you were a kid? Now, you can do it again…and share the science behind it!

And the final project will be creating a way to communicate with a friend…without speaking! Your students are sure to get creative with this activity!

Recap of Sound & Light Activities and Lesson Plans for 1st Grade

I promise this entire Sound & Light Investigations unit is TEACHER friendly! The kids will have so much fun learning and exploring that they won’t even realize they’re learning those new Next Generation Science Standards!

Go find it in The Lucky Shop here!

3 interactive weather science experiments for first grade

Weather science experiments are some of my very favorite to do with kindergarten and first grade kids. They are engaging, they provide powerful learning opportunities, and kids LOVE weather. Here are 3 kid-approved weather science activities that are easy to prep and sure to have your kids hooked on weather science!

did my shadow move?

This experiment will blow your kid’s minds! Every time I do this science activity with first graders, they are just so surprised, which makes it even more meaningful and exciting for everyone.

We do this shadow science experiment when we are learning about the patterns of the sun and day and night cycles. It is one of the first things we do before we jump into learning about the sun and the earth’s orbit.

Kids partner up and trace their shadows at the very beginning of the day and then make predictions on what will happen to their shadows.

At the end of the day, we come back out and retrace our shadows. And before they have even traced it out, get ready for the screams and giggles! It is SO much fun watching them realize their shadows have “moved!”

This shadow experiment blog post gives all of the nitty gritty details for how we manage this weather science experiment, how we record our shadow observations , and what we use to follow up with some powerful learning about earth’s orbit and the sun!

clouds in a jar

It took me a few years of teaching first grade weather lessons to get brave enough to do this weather science experiment with kids… and y’all! I have NO idea what I was scared of.

This weather science activity is super low prep with another super high learning impact! And anytime you can get shaving cream in the classroom… kids know you’re gonna have a good time! #iykyk

In this cloud in a jar weather science experiment , kids will fill their clear cup with water. We will put a shaving cream “cloud” on top of their cup of water.

Then, the kids will take turns dropping blue water on top of the “cloud.” They will predict and record how many water drops it will take before the cloud begins to rain.

This is another weather experiment where kids OOOOOH and AHHHHH when it starts raining in their cup. And it’s a powerful launch into a discussion about condensation and what makes a cloud finally start to rain!

The materials list and all the rainy details are in this cloud in a jar rain experiment post.

Catch a rainbow

At the risk of sounding like a broken record, this last weather science experiment is another one that is a real winner with a super high “giggle and wow” factor! Seriously!

In this rainbow science experiment , kids will shine a flashlight through a glass of water to try and catch a rainbow on their paper.

Must have for this weather science activity : classroom lights off! So, yeah, your kids will already be thrilled because turning the classroom lights off is like magic around here! 🙂

Rainbows, rain, and the water cycle are a big part of our first grade weather unit . But I have also done this experiment with preschoolers at church when we were learning about Noah’s Ark and it was easy for my 3-5 year olds too! (We just didn’t do all the writing!) This is such a great weather experiment for a wide age range of kiddos! Read all the extra details on the catch a rainbow science experiment here .

You can find all of these weather science experiments in this first grade weather unit . And you’ll find the catch a rainbow science experiment in this kindergarten Next Gen Science weather unit along with several other weather experiments!

Light Experiments

Nothing in the universe travels faster than light. (Rumors born in faculty meetings might be a close second, but light wins.) It’s easy to get kids engaged in the study of light. There are loads of light experiments that spark anticipation and wonder … some even feel like magic to young scientists. Like, 👆 Why does that  perfectly good straw look broken? 

And,  How can we pop a balloon without even touching it?👇

You can also DIY a little laser light show in your classroom with a can of Lysol and a cat toy! (Any aerosol spray will work, but why not kill a few germs at the same time, right?)

For this light experiment, darken the room and spray the Lysol for a few seconds. You should basically see nothing. Now do it again, but this time aim the laser light into the path of the spray. As the beam of light reflects off the moisture in the Lysol, you’ll probably hear,  “Cool!” and  “Can WE try it now?”

TIP: The darker the space, the better the results.

And, if you can get enough laser/aerosol donations, students can work in small teams of 2-4 and all together you can create quite a show!

IDEAS FROM PINTEREST

If you’re a first grade teacher and you’re planning a science unit on the study of light and sound, check out this Pinterest board:  Light and Sound Science . You’ll find so many great ways to support your science instruction with videos, books, integrated projects, and more.

LIGHT EXPERIMENTS

These SCIENCE LESSONS  give children the opportunity to learn how light behaves while learning key vocabulary words like energy , refract , transparent , translucent , and opaque . Each experiment comes with printable recording sheets, picture support, and a science page explaining what they observed.

• Can you flip the fish without flipping the card?
• How can you change the amount of light that can be seen?
• I bet we can pop a balloon without even touching it!
• Whoa … why does that paintbrush look broken?

👉A Fish Out of Water: Refracted light can reverse an image.

👉Let the Light Shine: Is it transparent, translucent, or opaque?

👉Ready, Aim, Pop! A light source can create heat energy.

👉The Broken Straw: Refracted light can split an image.

NONFICTION SCIENCE TEXT

This SCIENCE BOOK ,  What Is Light? , introduces children to the concept of light and how it behaves. They’ll learn about sources of light, how light travels, and how light impacts our daily lives. Key terms such as energy , source , and waves are emphasized in the text.

45 Easy Science Experiments for Kids

Hello, STEM! These simple DIY activities can be done at home or in school.

We've been independently researching and testing products for over 120 years. If you buy through our links, we may earn a commission. Learn more about our review process.

Imagine blowing the biggest bubbles imaginable — or even making bubbles within bubbles. Or sending vessels — rockets, tea bags, airplanes — soaring through the sky for impossible distances. Now imagine making things explode, or change colors, or reveal hidden messages with just a few simple mixtures.

First off, it's good to start them off with the scientific method. Give them a journal to record their observations, questions, hypotheses, experiments, results and conclusions. As always, safety counts: wear goggles and coats or aprons if need be (sometimes kids get a kick out of how scientific the protective gear makes them look), and always make sure that the kids are supervised when doing them. (Warning: Some of these are messy!)

These experiments are mostly designed for preschoolers through elementary schoolers — with a couple that are either demonstrations or better for older kids — but if you have a younger one, you can check out these 1-year-old learning activities , toddler learning activities and preschool/kindergarten learning activities , some of which also cover STEM subjects.

Floating Fish

Here's another one that deals with solubility and density.

• Draw the outline of a fish on the bottom of a glass plate or tray in dry-erase marker. Retrace your drawing to make sure all the lines are connected. Let dry for a minute or two.
• Fill the measuring cup with tap water. Place the pour spout just inside the corner of the dish and add water very slowly until it just covers the bottom. Be careful not to pour water directly onto your drawing or make splashes near it. The water will move toward your drawing, eventually surrounding it. Observe what happens. If the water splashes or it doesn’t work on your first try, empty the dish, erase the drawing with a paper towel, dry off the dish, and try again.
• Tilt the dish slightly from side to side. What happens? Jot it down.

The ink in dry erase markers is engineered to be slippery. It’s made with a chemical that causes it to easily release from surfaces. (Permanent markers are made with a chemical that makes the ink stick to surfaces, so be sure not to use these in your experiment!)

The easy-release ink lets go from a surface, but why does it float? There are two reasons. First, dry erase ink isn’t soluble, which means it won’t dissolve in water. Second, dry erase ink is less dense than the water, so it becomes buoyant, meaning it can float. When you tilt the dish, the fish moves around on the water’s surface.

Brush, Brush!

This one will really get them into brushing their teeth once they scientifically prove all the good things that toothpaste can do.

• Write on sticky notes: Soda 1, Soda 2, Juice 1, and Juice 2. Place them in a row on a counter.
• Fill two glasses halfway with brown soda and place behind the Soda 1 and Soda 2 sticky notes. Fill two glasses halfway with lemon juice and place behind the Juice 1 and Juice 2 sticky notes.
• Carefully place one egg in the bowl. Squeeze a big dollop — about one tablespoon — of toothpaste on top of the egg and gently rub the toothpaste all around with your hands until the egg is completely covered in a thick layer of toothpaste. Repeat with a second egg.
• Gently submerge the toothpaste-covered eggs into the liquids: one egg in the glass labeled Soda 1 and the other egg in the glass labeled Juice 1. Wash and dry your hands.
• Gently submerge the remaining eggs, without toothpaste on them, in the remaining glasses: one in the glass labeled Soda 2 and the other in the glass of juice labeled Juice 2. Wash and dry your hands. Leave the eggs in the glasses for 12 hours.
• After 12 hours, remove the eggs from the glasses of soda one at a time. Rinse them in cool water and pat them dry with the towel. Place each egg by the sticky note of the glass it was in. Are the eggs the same or different colors?
• Remove the eggs from the glasses of juice one at a time. Rinse them under the faucet and pat them dry. Place each egg by the sticky note of the glass it was in. Feel the eggs gently. Does one feel stronger or weaker than the other?
• Write down your observations in your science notebook.

The eggshells in this experiment represent the enamel (outer coating) on your teeth. Toothpaste cleans your teeth and prevents stains: it removes food and drink particles that are stuck on your teeth. Teeth can be stained easily by dark-colored liquids like cola, coffee or tea. The egg without toothpaste will be brown and discolored. The egg covered in toothpaste was protected from turning brown.

Toothpaste also protects your pearly whites from decay (breaking down). The egg without toothpaste left in the lemon juice was worn down and soft to the touch, while the egg that was protected with toothpaste is stronger. The lemon juice is acidic, and those acids broke down the shell just as acidic drinks can wear away your tooth enamel. When a tooth is worn down, a cavity can form more easily. But the fluoride in toothpaste mixes with your saliva to create a protective coating around your tooth enamel. It helps keep your teeth strong and cavity-free.

Milk Bottle Xylophone

No for an experiment in sound!

• Arrange six glass jars or bottles, all the same size with no lids, in a line. What will each jar sound like when you tap it with a spoon? Make a prediction, then tap each jar. Record your observations.
• Next, put water in each of the jars. Pour 1⁄4 cup (60 ml) of water into the first jar. Add 1⁄2 cup (120 ml) of water to the second jar. Continue in 1⁄4-cup increments, adding 3⁄4 cup (180 ml) of water to the third jar, 1 cup (240 ml) of water to the fourth jar, 11⁄4 cups (300 ml) of water to the fifth jar, and 11⁄2 cups (360 ml) to the sixth jar. Add a couple of drops of food coloring to each jar.
• What will each jar sound like? Will they sound the same or different than when the container was empty? Will they sound the same or different from one another? Record your predictions.
• Tap each jar with a metal spoon. Write down your observations about each jar’s pitch (how high or low a sound is) in your notebook.

Sound waves are created by vibrations, which are back-and-forth movements that are repeated again and again. Pitch depends on the frequency of the waves — how many are created each second. A high pitch is created by high-frequency sound waves, and can sound squeaky. A low pitch is created by low-frequency sound waves, and sounds deep and booming.

When you tapped the jar, it vibrated. The vibrations traveled from the jar to the water to the air and eventually to your ears. The jars with more water had a low pitch. The sound waves vibrated more slowly because they had more water to travel through. The jars with less water had higher pitches. The sound waves vibrated faster because they had less water to travel through. A jar with no water in it makes the highest pitch because it has the least substance to travel through.

"Elephant Toothpaste"

Okay, elephants don't really brush with this stuff, which is made from a chemical reaction between hydrogen peroxide, yeast, dish soap and a few other simple ingredients. But this experiment has a big "wow" factor since, when the substances are mixed, the "toothpaste" foams out of the bottle. You can use it to teach kids about catalysts and exothermic reactions.

Get the engineering back into STEM with this activity, which challenges kids to create a paper bridge that's strong enough to hold as many pennies as possible. How can they manipulate the paper to make it sturdier? (Hint: Fold it!)

See the paper bridge tutorial at KidsActivities.com »

Challenge your little scientist to lift up an ice cube with just a piece of string. It's possible ... with a little salt to help. Salt melts the ice and lowers the freezing point of the ice cube, which absorbs the heat from the water around it, making the water cold enough to re-freeze around the string.

Coin Inertia

Stack up about five or so coins on a piece of cardboard and place it over a glass of water. Then, flick the cardboard out from on top of the glass. Do the coins drop into the water, or ride with the cardboard? Due to inertia, they drop into the water — a very visual (and fun!) demonstration of Newton's First Law of Motion.

Apple Oxidation

What works best for keeping an apple from turning brown? Test to find out! Slice up an apple, and let each slice soak in a different liquid. Then take them out, lay them on a tray, and check the brownness after three minutes, six minutes and so on. Not only does this test the properties of different liquids, it also helps students practice the scientific method if they create hypotheses about which liquids would be most effective.

Chromatography Flowers

Chromatography is the process of separating a solution into different parts — like the pigments in the ink used in markers. If you draw stripes around a coffee filter, then fold it up and dip the tip in water, the water will travel up the filter and separate the marker ink into its different pigments (in cool patterns that you can display as a craft project). This family made the end-result even brighter by adding an LED circuit to the center.

Water Walking

You'll need six containers of water for this one: three with clear water, one with red food coloring, one with blue coloring, and one with yellow coloring. Arrange them in a circle, alternating colored and clear containers, and make bridges between the containers with folded paper towels. Your kids will be amazed to see the colored water "walk" over the bridges and into the clear containers, mixing colors, and giving them a first-hand look at the magic of capillarity.

4 Simple Experiments to Introduce Kids to Physics

It is never too early to start having fun with Physics!

This quick series of physics experiments is perfect for introducing little learners to concepts of push and pull! In the experiments that follow, kids will investigate how they can change the speed and direction of objects by applying varying degrees of strength. It’s a great way to get young students excited about physics and STEM in general.

Step 1: Introduce the Physics Experiments

First, connect motion to what the children already know. Ask them, “How do we move?” Have children raise their hands and demonstrate. Next, drop a stuffed animal on the ground. Ask students, “How can I make the stuffed animal move?” They will think about their past experiences with moving objects to derive an answer. Then, explain that a push and a pull are both forces. Force makes an object move or stop moving. When we push something, we are moving it away from us. When we pull something, we are moving it closer to us. (Act out motions with students: push = palms out, push away from body, and pull = two fists on top of each other, pull toward body.)

Brainstorm : Create a t-chart, write down objects that can be pushed or pulled (objects at home, in the classroom, on the playground).

Step 2: Do Small-Group Instruction  (Stations):

PHYSICS EXPERIMENT #1: SODA BOTTLE BOWLING

Push: Children experiment with pushing a ball hard and with less force to knock over soda bottles. They can compare a big push to a small push. What kind of push made the ball move the fastest? They will see how when objects collide (ball and soda bottle), they push on one another and can change motion.

PHYSICS EXPERIMENT #2: CHAIR PULLEY

PHYSICS EXPERIMENT #3: RAMPS AND MATCHBOX CARS

Push: Children create ramps using flat, rectangular wooden blocks and Duplo Lego bricks. They will investigate how the height of a ramp can change how fast and far their Matchbox car can go. They will also compare the distance and speed of the car on the ramp to using no ramp.

PHYSICS EXPERIMENT #4: SORTING PUSH AND PULL

Sort: Put out a paper bag that contains various real-world objects. Children collaborate and sort the objects using a Venn diagram (hula hoops). Children place the objects in the appropriate groups using this free printable”  push, pull or both .

Step 3: Reinforce the Concepts

After the physics experiments, children can play computer games to reinforce push and pull! I like these two:

• Push:  Piggy Push  from Cool Math Games
• Pull:  Hook the Fish  from Cookie

Or you can watch a  video  to reinforce pushes and pulls. For further reinforcement, the next day, have children go on a scavenger hunt and try to find things around the classroom that they can push and pull.

Step 4: Assessment

Children are assessed through observation, questions, and conversations while they work in small groups at stations, interacting with various objects that demonstrate pushing or pulling. I took notes and scored the children using a rubric  I made in iRubric. You can download it for free!

What Will My Kid Learn in First Grade?

See what educational milestones your child will achieve, what first graders learn, and how to help them master these skills at home.

First Grade Reading

First grade writing, number sense in first grade, measurement and geometry in first grade, time and money in first grade, science and social studies in first grade.

By the time they reach first grade, children begins absorbing new material like a sponge. What do first graders learn? For starters, they understand at least 20,000 words, have some impressive spelling skills, and can sense how words and language work. In math , they're getting faster by the week at adding and subtracting, and they're learning to solve word problems.

Despite these accomplishments, though, your first grader still needs plenty of encouragement. In fact, they needs it now more than ever, says Susan Quinn, a first grade teacher at Sacred Heart School in the Bronx, New York.

" Kids will start to not like school at this age if they feel that they're not smart or that they're not doing well," Quinn says. First graders can also talk more about their feelings, so be sure to listen and help out if your child gets discouraged.

Here are the important learning milestones children will typically achieve in the first grade, with tips for helping your kid stay on track.

First graders will be able to read at least 150 high-frequency words ("sight words") by year's end, and typically have improved phonics and reading comprehension skills by this time as well. They’ll also read grade-level books independently—and understand them.

Helping at home

• Give your budding bookworm plenty of opportunities to read aloud, at a level appropriate for the age of first grade students. Have them read you a short story while you're cooking, for example, or give them the important job of reading to a younger sibling.
• Take turns reading the pages, helping them sound out and learn unfamiliar words (use contextual clues like surrounding words or pictures), and keep discussing stories by asking questions ("Why do you think she did that?"). Help them learn prediction by asking, "What do you think will happen next?" and ask them to retell a story in a few sentences to practice summarizing.
• Always have kids' books or magazines handy if you need to wait somewhere, such as a health care provider's office or train station.

In the first grade curriculum, kids will learn to spell three- and four-letter words and write clear, coherent full sentences. By the end of the year, your child will be forming short paragraphs with at least three or four sentences, and should also structure sentences correctly by capitalizing the first letter and ending with the correct punctuation. They may also write basic short stories—perhaps about losing a tooth or riding a bike.

• Have your child keep a notebook at home , Quinn says, because first grade students love to write lists and notes to friends. This writing won't be graded, so your child should have fun with it. Encourage them to draw pictures and write without correcting spelling or grammar.
• Also feel free to give your child fun writing prompts . After you visit the park, for example, ask them to describe the interesting things they did. Give children prompts connected to reading, too. "After you've read Charlotte's Web , have them write about a pet that they would like to have, or ask what they would name a pet pig if they had one," Quinn suggests.

By the end of the year, your child will count, read, write, and order sequential numbers up to 100. They will also learn how to compare numbers using the signs for greater than, less than, and equal to. First graders can add whole numbers with a sum of 20 or less and subtract from a whole number 20 or less, and they will be introduced to the concept of place value when adding and subtracting two-digit numbers .

• Help your first grader understand the importance of math in everyday life. Encourage your child to count the number of steps it takes to walk from the front door to the kitchen. Then, ask them to count the amount of steps it takes to walk from the front door to their bedroom. Ask them to identify which distance is greater.
• Hang up a number chart in your child's bedroom showing numbers one to 100, and find a place mat with numbers to practice counting during meals. While waiting in line, practice counting by twos and fives together.

As part of the first grade curriculum , kids will compare the length, weight, and volume of objects. They’ll measure length using small things, such as paper clips or pencils. Finally, teachers will explain how to compare, identify, and describe common shapes.

• When cooking, show your child the numbers on recipes and talk about what they mean as you measure ingredients. Grab a pitcher and a variety of cups, and experiment with volume by pouring the same amounts of liquid into different-size cups and different amounts into same-size cups.
• Encourage your first grade student to talk about 3D shapes of objects, such as a tissue box (cube) or ball (sphere), and discuss the different architectural shapes of buildings outside. "Shapes can be a lot of fun," Quinn says. "Seeing these as part of their life, not just something taught in school , definitely makes a difference."

First grade students will be able to read a clock face to the nearest half hour. They’ll understand concepts such as "an hour from now," and they’ll name the days of the week and months of the year. Finally, your first grader will learn to identify different coins, understand the value of each one, and combine different amounts. (For example, two nickels equals one dime).

• Find an analog clock and track the big hand each hour.
• Look at monthly calendars together, and let your child mark important dates and events.
• Keep talking about what you did "today" and "yesterday," and what you'll do "tomorrow" or "next week."
• Play games with coins. Take a pile of spare change and ask your child how many ways they can make 10 cents, 25 cents, or 75 cents.
• When you go grocery shopping , discuss how much money you'll need to buy milk and bread.

During first grade, your child will learn the basic fundamentals of science . Not only will they learn about the difference between living and nonliving things, they also will learn how to collect data and record observations particularly with regard to weather patterns, lifecycles of plants, and the cycles associated with the the sun, the moon, and the ocean.

They also will gain a basic understanding of social studies. For instance, they will learn about important events, community involvement, and symbols that represent the United States. 

• At home, you can try planting seeds and observing and tracking their growth.
• Take a trip to the zoo and note the different characteristics of the animals. You also can sort plastic animals by their features and record the differences.
• There also are a variety of STEAM projects and crafts you can do at home.
• As for social studies, try looking at a map of the United States together to familiarize your little one with the different states. You also can talk about the flag and what the Stars and Stripes stand for.
