Science Experiments for Kids
Exploding Bags from Happiness is Homemade: Kids of all ages get a kick out of this experiment. Learn how vinegar and baking soda react with a big, satisfying POP at the end of the experiment.
Balloon Science from Kiddy Charts: Yet another experiment for baking soda and vinegar, this experiment demonstrates the CO2 gas inflating the balloon as the chemical reaction occurs. How cool!
Rain Cloud in a Jar from Natural Beach Living: This weather experiment is a simple way for kids to explore clouds and rain. It’s so simple to set up. You just need shaving cream, food coloring, and a glass of water!
Oil and Water Science from Happiness is Homemade: What happens when you combine oil and water? This colorful density experiment will help kids easily understand the concept.
Rainbow in a Jar from Primary Playground: Here’s another density experiment using sugar water. It creates a beautiful rainbow in a jar, so it’s a terrific experiment for spring.
Vinegar Volcano from Happiness is Homemade: This is your classic baking soda and vinegar experiment in a volcano. It’s always a hit with the kids!
Orange Volcano from The Art Kit: Here’s another variation of baking soda and vinegar volcanoes done inside an orange. This is handy if you don’t want to build a volcano first.
Racing Rainbows from The STEM Mum: Who doesn’t love experiments involving candy? See which type—Skittles, M&Ms, or Smarties—fills in the plate with a rainbow the fastest.
Melting Ice Experiment from The Chaos and the Clutter: Here’s a simple experiment that you can do with things you already have in your kitchen. You’ll just need some ice, water, sugar, and salt. Find out which method melts the ice the fastest.
Simple Light Refraction Experiment from Look, We’re Learning!: This experiment is quick and easy to set up, and it’s a simple way to teach kids about light refraction in water using a water bottle, a post-it note, and a marker.
Car STEM Experiments from Taming Little Monsters: Study how cars roll differently when variables such as the height of the ramp, angle of the ramp, and weight of the car change.
Toilet Paper Science from Pink Stripey Socks: We’ve all been going through a little more toilet paper than usual, no? Why not study different toilet paper brands to see which one is the softest… or the strongest… or the most absorbent!
Coke and Mentos Experiment from Glue Sticks & Gumdrops: You’ve seen the pictures and the videos. This experiment is just plain fun! Little kids will just enjoy the geyser of liquid that erupts. However, with older kids, you could try different types of soda to see which one produces the biggest geyser, etc.
Frozen Water Expansion Experiment from A Little Pinch of Perfect: Water expands as it freezes, and this experiment offers a colorful visual that shows that on an easy-to-understand level.
Egg Parachutes from JDaniel4sMom: No matter the time of year, if you look around in your kids’ toys, you can probably find plastic eggs (or at last some halves, which are all you need for this experiment). Put them to use making fun parachutes! Throw them in different ways, drop them, change up the variables. There’s so much you can do with them!
Sink or Float Egg Experiment from Kindergarten Worksheets and Games: Will eggs float in regular water? How about saltwater? Find out with this simple study!
Walking Rainbow STEM Activity and Printables from Happiness is Homemade: Kids will get a kick out of this colorful science experiment that demonstrates capillary action. You may have also seen this experiment called “Walking Colors” or some other variation. The resulting rainbow of colors is stunning.
Grow a Pot of Gold by From Engineer to Stay at Home Mom: This is a fun experiment for St. Patrick’s Day, but really, you can do it all year long. Grow golden sugar crystals to make your own pot of gold. Be patient—you’ll need about a week for your sugar crystals to grow. And here’s the experiment done with Borax crystals instead of sugar crystals. You’ll only need a day for this one!
Catapult STEM Activity from Go Science Kids: Make a catapult out of upcycled materials you already have at home. The kids will have so much fun launching small objects with their catapults and seeing which projectiles will shoot the objects the farthest.
Bean in a Jar Experiment from Science Sparks: You probably did this experiment in school yourself, but it’s always a fun one. Grow a bean in a jar without soil! You’ll only use a moist paper towel and a bean to study this sprouting activity.
Celery Science from Rainy Day Mum: This easy experiment using celery, water, and food coloring is an easy way to demonstrate the transpiration process in plants.
Eggshell Garden Science from Steamsational: Compare growing conditions for plants with this eggshell garden activity. Place on in a sunny spot, one in the shade, and one in the dark indoors. You can try several other variations, too. After your seeds have sprouted, you can simply pop those eggshells along with their plants right into the ground!
All of these STEAM science projects for kids are SO much fun, and I love that you don’t need any special equipment! Which one will you try first?
