Fifth Grade Science Fair Project Ideas

Science Experiments for 5th Graders

5th Grade is a fantastic age to do science. The kids are old enough to start doing some projects independently and they have an insatiable curiosity and passion for learning. Especially when it is hands on experiments with great wow factor! These science experiments for 5th graders will inspire curiosity, spark a passion for learning, and excite young scientists. If you are working on lesson plans for your grade 5 students (or 5th year), here are some of our top picks!

The Best Science Experiments for 5th Graders

What you will discover in this article!

Although the topics covered in 5th grade vary based on where you are in the world, there are some consistent themes that are commonly covered at this age. We’ve looked into syllabuses from all over and came up with this list of topics that appear most often. These themes include lesson plans around:

• Earth and Space
• Lifecycles (plants and animals)
• The human body
• Electricity
• Chemistry (such as crystallization)
• States of Matter

Scientific Method

Phew! That’s a lot! But trust me, it can also be fun! Plus this is based on reviewing school curriculums all around the world. You don’t need to tackle all of these subjects. Or maybe you do if you have a passionate young scientist!

Based on this list of topics I have gathered up some of our favourite science experiments (and STEM projects) that are perfect for adding to your 5th grade science lessons.

5th Grade Science Project Ideas

Oobleck states of matter exploration.

Oobleck is always a hit with kids! We have done a lot of different Oobleck experiments over the years. One of our favourites was a science fair style investigation which also worked on the sense of touch (learning about the body), as we explored different recipes and evaluated how the texture varied with each recipe. But that is just one of many awesome Oobleck ideas we have done. Check them out!

Growing Crystals (Chemistry)

Growing crystals is a great way to introduce students to lab work and chemistry. Usually before this age they have already played around with the basic baking soda and vinegar type reactions , but if they haven’t definitely add those into the mix too. For crystals growing there are lots of different ways to grow crystals. Some use borax which is not available in some countries, but we also have crystal growing options using other solutions such as alum, salt or sugar! With sugar crystals (candy science), you can also explore taste, which ties into the human body studies too.

Building a Heart Model

Learning about the human body is fascinating and important. We want kids to understand their bodies, how they work, and how to properly care for their bodies. One of our favourite body learning activities was building a heart model that we made beat and move “blood” around. It was a great project for 5th years!

Windmill (STEM Project)

I love when I can combine a great science project with a fantastic book. If you decide to try a windmill engineering challenge (a brilliant STEM Project for 5th grade) there is a fantastic book called The Book Who Harnessed the Wind. This unit study is fantastic because it brings together literacy/reading, history (it’s a true story) plus engineering and physics lessons. The book is a great read with multiple levels of difficulty available.

Elephant Toothpaste

Elephant Toothpaste is a great science experiment for grade 5 that explores chemistry, biology, and states of matter. Plus it is a lot of fun for students!

Space Projects

Space is a fantastic topic to tackle with 5th graders! They love learning about the stars, planets and and our place in the universe. We have been obsessed with our space studies for many years and have compiled a great resource with tons of space related science experiments , all perfect for 5th grade! My personal favourite is the pipe cleaner constellations and the space inspired bath bombs!

Coding Challenges

Coding is the second language of today and the future and something all kids should explore and learn. It can be intimidating to teach coding if it is not something you are familiar with, but thankfully there are a lot of programs and options out there to help kids learn coding. We have a number of screen free options, plus there are programs, toys and more all designed to make learning coding fun and easy!

Circuit Building

Light it up! Kids in grade 5 are the perfect age to build circuits and learn how electricity works. From salt circuits, to circuits built with food, to circuit bugs, there are so many cool options for you to explore.

Wingardium Leviosar

Magnets are fascinating for kids and a great tool for doing some simple science experiments. One of our favourite science experiments we did in grade 5 tied into the Harry Potter books, Wingardium Leviosar Magnetism Experiment . Making this another fun cross subject activity!

Water Science

Water is an incredible tool for doing science experiments with liquids in 5th grade. You can use it to study states of matter, physics, chemistry, and more. It is readily accessible, safe for kids and the experiments are a ton of fun! We have done lots of experimenting with water science over the years. Check out our comprehensive resource on Water Science Projects for the perfect experiment for your studies.

Make It Move

Make it Move is a fantastic classroom challenge, where kids need to innovate and come up with ways to make their car race across a track or table without pushing it! Give them a variety of supplies and a matchbox car, then watch those imaginations go wild.

Balloon Races

A wonderful activity for introducing physics concepts to kids in 5th year is balloon races . It gets them up and moving and having a blast exploring these fundamental concepts around Newton’s Laws of Motion. Budget friendly, fun and perfect for home or the classroom, this is one activity you must do!

Layers of the Earth Soap

Learning about the layers of the Earth with this soap making project is a great way to explore our gorgeous planet. Plus, every time the kids wash their hands they will remember the lessons on the planet layers, helping to reinforce those concepts.

Climate Change and the Greenhouse Effect

Students will gain a greater understanding of the water cycle, climate change and the way greenhouse gases capture and hold heat in this experiment in a jar . Fantastic as an experiment, science fair project, or a classroom demonstration.

Lifecycle Activities

Learning about lifecycles is a very popular topic for our 5th grade students. We have a fun Lifecycle Decoding Activity that is perfect for some screen free learning. Plus it combines coding skills with learning about lifecycles.

Rain Clouds

Looking for a gorgeous, simple, and fairly quick experiment? Try this Rainbow Rain Clouds experiment and learn how clouds work when it rains. It’s easy, fast and kids can do this experiment independently.

One of the key concepts kids should be learning not just in grade 5 but throughout their schooling is the Scientific Method . Using the method should become natural and easy with practice and encourages critical thinking and analysis which is important for all students to master.

The Science Fair

Grade 5 is a very popular grade for science fair projects! We LOVE doing science fair projects and have so many ideas. Check out our comprehensive resource to find the perfect science fair project idea. We also provide tips on how to prepare, what to expect, and topic ideas.

Amazing 5th Grade Science Fair Projects That are Kid-friendly

5th graders are inquisitive, curious, and willing to experiment with what fascinates them. Science projects give students a chance to understand complex, scientific phenomena through simple experiments. Encourage this need to learn, discover and prod, by introducing them to these fascinating ideas for 5th grade science fair projects.

Like it? Share it!

Science fairs are a gateway to an opportunity where students can display their work proudly, by using various materials that mind-boggle those who chance upon each stall. It’s not only a valuable learning experience, it’s a chance to sharpen their communication skills at a young age; they will be nervous at first while speaking, but it will slowly come naturally once they get into the flow of explaining what their project is about.

5th graders are abuzz with energy and are open to all sorts of things, where science becomes an instant favorite as a subject, as they grow. Devising project ideas for fifth graders shouldn’t be very difficult, since children of this age are eager to experiment.

Kids have questions about the world and are interested to know about why things happen the way they do. They are so enthusiastic, that they’ll do anything to satisfy their hunger for knowledge. They’ll dirty themselves in muck to collect earthworms, enter turbid waters to closely inspect ‘aquatic’ life, or climb tall trees to examine a bird’s nest. Their craving for learning is insatiable where it’s best to channelize this curiosity in the right direction, by encouraging them to participate in science fairs, exhibitions, and project competitions. These 5th grade science fair projects, will teach them how the things around us aren’t as ordinary as they seem.

5th Grade Science Fair Project Ideas

Magical frost.

Things Required

• A cup and a ½ of Epsom salts
• 2 cups of water
• A glass saucepan
• 2½ tablespoons of powdered laundry detergent
• A paint brush
• A medium-sized sheet of ordinary glass
• 2 oz. of dextrin (a.k.a, baked corn starch – optional)

Procedure Step 1 : Place the glass saucepan over a medium flame on the stove, and pour into this the two cups of water.

Step 2 : Wait for the water to start bubbling before adding the Epsom salts. Stir thoroughly for about 30 seconds until some of the salts dissolve, leaving the rest settled at the bottom of the saucepan.

Step 3 : Take the saucepan off the heat and stir into this, the powdered laundry detergent and dextrin.

Step 4 : Wait for the water to cool down, before using the paint brush to slather the mixture across the glass sheet; leave it aside to dry. If this is too messy, a good alternative would be to pour the mixture in a shallow tub before submerging the glass sheet into it. Leave the tub in a sunlit area for the glass sheet to dry faster, while the excess water evaporates. The result will be a frosted glass with vivid detailing.

What Kids Will Learn

Kids will learn how Epsom salts upon drying, will crystallize to form frost-like deposits across the glass, as it coalesces with the other ingredients to form a stiff bonding. The glass can be used as a decorative piece in the classroom, or at home where it can be on display for all to see post the science fair.

Jack and the Beanstalk

• A handful of beans
• Watering can
• Rubber gloves
• Paper and colored pencils

Procedure Step 1 : Choose any kind of beans that you’d like to plant (mung beans, for example), and let kids place these in individual pots. Teach them the importance of using gloves while potting and handling plants, to avoid contaminating their hands.

Step 2 : Using an index finger, create little holes in the mud, spacing them apart so that the beans have enough room to grow.

Step 3 : Once the beans are tucked into their little mud pockets, cover them up by sliding mud across these openings.

Step 4 : Pat the soil gently for a few seconds (to even it out), and then pour a little water into the pot from the watering can. Leave it on a windowsill that receives plenty of sunlight, and have kids water it twice daily during school hours. Have them record their observations by drawing it on paper, and marking each day’s date as well.

Kids will learn about how plants grow, and what it takes to nurture them into full-grown spectacles. It will ‘sow’ in their hearts the desire to plant something on their own at home, where parents can play a major role in encouraging this particular interest. Beans aren’t the only things that can be experimented with. Try fast-blooming plant varieties like marigolds and cosmos.

Magnified Beauty

• A bunch of colorful leaves
• Large magnifying glass

Procedure Step 1 : Tear a leaf into half (or scrape the top of it), and stain the exposed edge with a single drop of red dye.

Step 2 : Sandwich the leaf between two microscope slides, and have students record their observations under the microscope.

Step 3 : They will notice how intricate the inside of a leaf is, as the red dye highlights the transparent bits. It is truly a sight to behold for a 5th grader.

Step 4 : After this experiment, take students out into an area where there is an abundance of plant life, and using magnifying glasses, have them record their observations by analyzing flowers, leaves, or even insects.

Kids will learn about the marvels of nature and how plants look ordinary to the naked eye, but are in fact a whole different story when closely examined. Help them identify the plants that they chance upon, using a reference book that enlists all kinds of flowers and non-flowering plants. The microscope experiment can be used to examine not just leaves, but petals as well.

Handmade Sundial

• 1 sturdy stick
• A handful of pebbles

Procedure Step 1 : Find a sunny spot to carry out the experiment, whether it’s at the beach, a backyard, or school playground. Bury the stick in the mud / sand and have kids take notice of the shadow it casts.

Step 2 : Explain to them how the shadow will start to shift, depending on the movement of the sun’s rays, much like that of an old-fashioned sundial. Showing them what a sundial looks like beforehand, will make them understand the experiment better.

Step 3 : Track the shadow’s movement by keeping a clock on hand, marking the time in a notebook before placing a pebble where the shadow of the stick falls.

Step 4 : Tell kids to check on the dial every 3 hours, marking the time in their notebooks along with a diagram of the sundial. They must also place a row of pebbles along the length of the stick’s shadow, and draw the number (that signifies the time) in the mud / sand using a pencil. They must be whole numbers, so that they can create a sundial that has a complete rotation of 9 – 12 – 3 – 6 – 9.

Kids will learn a fun way of telling the time, and can create their own kind of sundial at home using creative materials. Parents / teachers can help them put a sundial together for the science fair project, using things like cardboard, paint, stickers, glitter, and other imaginative add-ons.

Color-Changing Marvel

• Celery stalk (or any light-colored flower on its stem)
• Food coloring (any one color)
• Tall glass of water

Procedure Step 1 : In a glass of water, add 3 tablespoons of desired food coloring, briefly stirring the solution so that the water is a solid color.

Step 2 : Place the celery stalk (snip the bulbous end off) or flower in an upright position in the glass of colored water.

Step 3 : The following day, students will be in awe to witness the celery stalk / flower carrying coloration changes, that it absorbs from the colored water.

Kids will learn about how plants sustain themselves, using their roots or exposed ends (like the celery stalk) to suck in water. This experiment doesn’t have to be restricted to a glass of water. To change the colors of white flowers, a potted plant can be watered with colored water instead of regular water. Let students experiment with an entire pot of white lilies or roses, to give them a beautiful blush once water is absorbed.

Other Science Fair Projects to Try

#Demonstrating the laws of motion # Showing experiments on the uses of solar energy # Making a volcano model # Demonstrating the anomalous expansion of water # Conducting litmus tests to identify acids from bases # Distinguishing a boiled egg from a raw one # Experimenting with how music helps plants grow # Testing the effects of salt on the freezing point of water # Demonstrating how the color of an object determines its size, according to visual perception # Testing the effect of temperature on a magnet’s properties # Making miniature models of simple machines # Comparing people’s pulse rate from different age groups (using a stethoscope) # Doing a comparative study of the time taken by different people, to respond to the same stimuli

These ideas for 5th grade science fair projects are a fun mix of different experiments, that kids can try out at home before putting it up on display. Once they get the hang of doing the experiments on their own, have them come up with others that they’d like to try, by performing the experiments in the class laboratory first.

Science projects provide students with the means to apply scientific concepts to a practical situation, experimenting with what they read in books. Projects serve as an excellent learning experience for students, as they can put into practice all the interesting scientific theories they are taught in class. Help students conduct thorough research on the subject of their project. Guide them in the analysis of experimental data and in deriving conclusions. Warn them of the safety precautions they need to take, so as to avoid any mishaps. Most importantly, give these inquisitive young minds the freedom to experiment. You never know, these kids could be ‘scientists-in-the-making’.

30+ Science Fair Projects That Will Wow The Crowd

February 20, 2022 by Ana Dziengel Leave a Comment

Are your children signing up for the science fair this year? Have you begun the arduous task of looking for  science fair projects  that might pique your child’s interest? Or do you have a child who already has ten ideas they have been dying to try?

The science fair is a great school tradition and a memorable experience for many children (I still remember the life size plaster penguin I made in 5th grade), and if your school doesn’t conduct one, consider starting it!

This year if you are on the lookout for science fair projects I challenge you to think beyond the vinegar volcano (we have “Volcano Alley” at our school because there are so many volcano projects every year). I know, vinegar volcanoes are like a rite of childhood passage, but there are so many other amazing science ideas out there! I have compiled a list of 30+ science fair projects for kids based on their grade level below. Before we get started I wanted to share some tips for getting the most out of the science fair.

This post contains affiliate links.

Science Fair Tips

• Don’t do the project for your child! This is my number one tip. Many parents have a tendency to jump in and make children’s work “more presentable” or to assist their child so much in the project that it’s hard to know who actually did it. Listen I get it, science is fun and you want your child to have a wonderful presentation…but that’s not really what the science fair is about. It’s about your child learning how to do scientific research and present their findings in their own way. Think of yourself as a helpful guide NOT an assistant, and definitely not the boss.
• Choose something age  appropriate  When your child is choosing the science fair idea they want to try, make sure it’s age appropriate. Sure we’d all love to make a working robot but there’s nothing more frustrating than trying a project that may be too advanced for the skills of your child. And that’s when a lot of parents resort to doing the project instead. Not a good solution. So make sure your child is capable of completing the steps them self.
• Make a list of three ideas Have your child select three science fair project ideas and then go over the choices with them. Make sure they understand the steps involved in each project and wether or not they feel comfortable in executing those steps on their own with your guidance.
• Follow your child’s interests Encourage your children to explore some ideas based on interests they already have. Here’s a list of science books with projects based on things your child already loves!
• STEAM it up! STEAM projects rock the science fair!!! A great way to get kids to become more familiar with STEAM concepts it to pick science projects that crossover into art, math, engineering and more!  Two STEAM books to consider are  STEAM Kids Play and Learn (my book!) and   STEAM Kids ebook.  Both books will get you started with some great ideas!
• Read our Science Fair Mini Guide I created this mini guide to walk kids  through all the steps for completing their science fair project. You can check out the full guide here: 

Speak like a scientist! Science Vocabulary to use in your presentation

We’re almost ready to get to the projects! Before we begin, let’s review some science terms. In fact, using these terms in your science fair presentation will be sure to impress your friends and adults!

• When you watch, see, or notice something you are making an observation
• When you ask who, what, when, where, why, or how, you are forming a question  
• When you read a book or an article about your observation, you are doing research
• When you make a guess based on your observation, question, and research, you are forming a hypothesis
• When you test your hypothesis, you are conducting an experiment
• When you change one factor in your experiment at a time while keeping everything else the same, you are changing a variable
• When you take notes in your journal and write down what you see happening in your experiment, you are logging data  
• When you examine, or look at, your data, you are analyzing it
• When you are able answer your question, you are coming to a conclusion

30+ Science Fair Projects for Kids 

Now let’s get on with the science fair projects! I have organized the projects by age/grade level. Click the titles to be taken to the project instructions, unless the instructions follow below.

If you’d rather have the science fair projects list organized by subject you can download our hyperlinked PDF by subscribing to our email list here .

3. Shiny Pennies

A classic experiment that kids love is Shiny Pennies . Collect dirty tarnished pennies and have kids soak them for a minimum of 5 minutes in different acidic liquids. We used vinegar, salsa, lime juice, and lemon juice.  After soaking, remove them from the solution and rinse in soapy water then compare which ones are shiniest. Take notes on which acid worked best to shine the pennies. Variation: Don’t rinse all the pennies after removing them from the different liquids. Can you see a difference in the rinsed vs. non-rinsed pennies? Leave them overnight and see if any of the copper oxidizes (turns green) on the non-rinsed pennies.
