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.

25 Quick and Easy STEM Activities for 5th Grade

Categories STEM Activities

All everyone seems to talk about right now are STEM activities. STEM activities can be quite complicated, but they don’t have to be. These easy STEM activities for 5th grade are perfect for kids in fifth grade and teach the basics of science, technology, engineering, and math.

STEM activities are so much fun, and fifth graders will have a blast with these in the classroom or at home.

50+ STEM Projects for 5th Grade

Kids will love these fun STEM activities for 5th grade and they are the perfect STEM activities to try in the classroom or at home if you’re just getting started with STEM projects.

How to do STEM Activities for Fifth Grade

A STEM activity is an activity that contains elements of science, technology, engineering, or math, and sometimes two or more of those disciplines. When we do STEM activities, we like to include three of the letters if possible.

In a STEM activity, children are learning how to use several types of knowledge together to solve a specific problem.

We like to make our STEM activities fun for fifth graders because if STEM activities aren’t fun, kids will start to hate science.

Why Should Teachers Try Fifth Grade STEM Activities?

There are a lot of reasons to do STEM activities in 5th grade, not the least of which is that it’s required by many schools today.

Schools have recognized the importance of STEM education and it’s a large part of most elementary schools.

When doing fun STEM activities, elementary kids learn a lot more than just science, technology, engineering, and math. They can also learn:

• Problem-solving
• Creative thinking

My daughter is currently in fifth grade, and thanks to our focus on STEM at home, she consistently comes home with 100s on all her science projects and STEM challenges.

What Do Kids Learn Doing STEM Lessons in 5th Grade?

My favorite thing about fifth grade STEM activities is how it teaches kids that what they learn in school can be applied to life. There aren’t many other subjects in school that use several subjects at once, although once you’re out of school you constantly use things together.

What I love about STEM activities is that it provides a more holistic approach to education, and there isn’t really a “right” answer. This makes it easier for kids to learn the actual concepts, and they aren’t afraid of getting things wrong.

You can often tell which kids are involved in STEM activities based on how they answer questions.

10 years ago, kids were paralyzed to get the “wrong” answer and would often not engage in lessons.

Most kids today are ready to jump in and explore a concept, and I attribute much of that to the newer way children are taught in school, which includes a lot of STEM-based learning and integrative learning in other areas.

Tips for Doing STEM Activities in the 5th Grade Classroom

If you’re doing STEM activities with a group of kids, you’ll have to keep a few things in mind. Here are my best tips for completing STEM activities in a group:

• Set up in advance
• Show a demonstration
• Make sure kids know how to use equipment
• Have a dedicated time for experimenting
• Have a dedicated time for recording results
• Have a dedicated time for analyzing the experiment
• Make a part of the lesson clean-up time

If you follow these tips, it’s easier to do hands on projects with kids and you’ll have less of a hard time getting the class to focus. In a hands-on learning environment, elementary kids can easily get off track and lose the lesson, so organization is a must.

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.

None of this is magic. It's all science that you can do at home, most likely with ingredients you already have in your house. So, next time you need a boredom-busting indoor activity on a rainy day or a DIY project to get their minds humming, try one of these best at-home science experiments for kids , which cover topics like cover magnetism, surface tension, astronomy, chemistry, physics and more.

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.

Grow an Avocado Tree

For an easy lesson in Earth Science, your family can grow an avocado tree from a pit. You can buy an AvoSeedo kit , or just peel the seed and suspend it over water with toothpicks.

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.

Paper Bridge

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.

Coffee Ground Fossils

By making a salt dough with coffee grounds and pressing various shapes into it (toy dinosaur feet, seashells), kids can get a better understanding of how fossils are made. If you poke a hole in the top before it dries, the kids can hang their "fossils" up in their rooms.

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.

Cool 5th Grade Science Experiments

How to Make a Rainbow Science Experiment: Refraction

In the distant future, young students may build science experiments that make objects levitate or transport into alternate dimensions. However, 5th graders today perform experiments that adhere to our current physical laws. That doesn't mean all experiments must be as mundane as documenting the growth rate of lettuce. Ideas for cool, crowd-pleasing 5th grade experiments are all around you.

Name That Tune

Explore your musical side and learn about sound wave propagation by building an H20 xylophone. Arrange some glasses in a row and place a little water in the first glass. Increase the amount of water you add to succeeding glasses. When you're done, the first glass contains very little liquid, while the last one is almost filled with water. With a spoon, tap the glasses in different orders and note how you hear unique melodies. This musical effect occurs because of the way sound waves travel through a medium. When you tap a glass that doesn't have much water for sound to pass through, you hear a higher-pitched sound. Tap glasses that have more water through which sound must travel and you hear lower-pitched sounds. You may have seen people perform this trick on TV using wine glasses. With enough glasses filled with varying amounts of water, people can play every note on the scale.

Fun With Weather: Vortex in a Bottle

Earth perpetually releases pent-up, energetic fury in the form of hurricanes, tornadoes and lightning. The safest way to explore these types of dangerous meteorological displays is in a controlled, miniature science experiment. Build your own tornado vortex by filling a smooth-sided plastic bottle 2/3 full of water and pouring in some glitter. Turn another empty, smooth-sided bottle upside down and place its mouth over the bottle that has the water. After you tape the bottles together securely, invert them so the bottle with water is on top. Swirl the bottles in a circle, and a tornado vortex forms. This effect occurs because your swirling motions cause the water to move in a circular motion -- similar to the way tornado winds do. When the water pushes outward from the force of the motion, air flowing from the bottom bottle to the top creates the vortex. The glitter simply helps you see the vortex more clearly.

The Explosive Power of Carbon Dioxide

Carbon dioxide, a greenhouse gas that warms the planet, is also the ingredient that gives soft drinks their fizz. If you'd like to see the explosive side of this gas, create a geyser similar to Old Faithful. Place a dozen Mentos candies in a test tube and then place a 2-inch square piece of cardboard on top of it. Hold the cardboard, flip the test tube over and place it over the mouth of an open bottle of diet cola. Remove the cardboard quickly and run away from the bottle -- if you don't want to get wet. The candies fall into the soda and create an explosive reaction that sends the liquid spewing like a geyser. This doesn't happen whenever you drink soda because carbon dioxide is dissolved in the liquid. Because a Mentos candy has hundreds of irregularities, bubbles form around them, causing a tremendous release of carbon dioxide when Mentos fall into the soda.

Colors From Nowhere

White light consists of red, green, blue and other colors you don't see on a sunny day. When a rainstorm dissipates, you may spot them in a magnificent rainbow. Generate these colors by filling a pan or large shallow bowl 2/3 full of water and placing it on a surface so that sunlight falls into the water. Position a small mirror under the water so that sunlight strikes the mirror. Finally, hold a sheet of white cardboard or paper above the water so that light from the mirror falls on the cardboard or paper. Instead of white light, you'll enjoy the colors of the rainbow. The mirror and water function as a prism -- a device that splits incoming white light into its component colors. Normally, all colors in a beam of light travel at the same speed through a vacuum. Light at one end of the spectrum moves faster through a medium than light on the other end of the spectrum. When light's velocity changes, so does its direction creating what scientists call refraction.

Plant Growth Experiment

Ever wonder what makes plants grow the best? Try this fantastic plant growth experiment , where you explore how light, water, and temperature affect plant growth. Follow along to see which conditions will help your plants thrive the most!

Fun and Easy Plant Experiment for Students

Plants need certain things to survive and grow: light, water, and the right temperature. Explore how light, water, and temperature changes impact plant growth. This fun activity also teaches important biology concepts like photosynthesis and plant adaptation, along with applying scientific methods .

💡Explore our Biology Projects , including osmosis , capillary action , and plant cells .

Recommended Grade Level: 4-6th Grade

📝 A printable journal page is included to track your plant’s progress and add to a science notebook!

Here’s what you need to get started:

• 6 small potted plants (all the same type)
• Potting soil
• Ruler (for measuring plant height)
• Watering can
• Thermometer
• Grow lights or access to sunlight
• Labels for each plant
• Printable observation journal (included below)
• Camera (optional for photo observations)

How to Set Up: Hands-on Plant Growth Activity

Step 1: Set Up Your Experiment Divide your six plants into three groups of two and label each plant with a number. Each group will test different conditions: light, water, or temperature.

• Group 1: Light Experiment : Place one plant in a sunny spot and the other in a dark room.
• Group 2: Water Experiment : Water one plant daily and the other once a week.
• Group 3: Temperature Experiment : Put one plant in a warm spot (room temperature) and the other in a cooler place.

Step 2: Make Observations Measure each plant’s height every two days with a ruler and record your findings. Pay attention to the color, size, and health of the leaves. Write these observations in your journal.

Step 3: Create a Growth Chart Using the printable observation sheet below, chart each plant’s growth, including the plant’s height, the number of leaves, and any visible signs of health or stress. Compare how the plants in each condition grow over time.

Step 4: Analyze the Results After two to three weeks, review your data. Which plants grew the most? Which conditions seemed to help the plants grow best? Encourage students to reflect on how light, water, and temperature affected plant health.

Applying the Scientific Method

The scientific method helps students explore how light, water, and temperature affect plants. Here’s an example:

• Ask a Question : How does light, water, or temperature affect plant growth?
• Research : Learn about plant needs, like photosynthesis and proper hydration.
• Hypothesis : Make a prediction. Example: “If a plant gets more sunlight, it will grow taller.”
• Experiment : Follow the steps, changing only one variable (light, water, or temperature) while keeping the rest constant.
• Record Data : Track plant height and health in the journal every few days.
• Analyze : Look at the results. Did the plants with more sunlight grow more? Did temperature affect growth?
• Conclusion : Was the hypothesis correct? What did you learn?

The Science Behind Plant Growth:

Light is crucial for photosynthesis , the process by which plants make food. In this experiment, you’ll see that plants in full sunlight grow better than those kept in darkness. This is because, without light, the plant can’t perform photosynthesis, leading to slower growth and poor health.

Water is necessary for transporting nutrients throughout the plant. When a plant doesn’t get enough water, it may wilt or not grow as quickly. By comparing a plant watered daily to one watered weekly, you’ll notice the differences in growth and vitality.

Temperature:

Plants also grow best within a certain temperature range. Warmer temperatures can speed up a plant’s metabolism and growth, while cooler temperatures may slow it down. This experiment allows you to observe how plants in warm versus cool environments develop over time.

The Role of Photosynthesis:

Plants use light, water, and carbon dioxide to make food essential for growth. In the light experiment , plants kept in the dark won’t be able to photosynthesize effectively, so their growth will be slower or stunted. The experiment shows how important sunlight is for plant health and survival.
