10 Easy Science Experiments For Kids

BTS Science Experiments

Water density. Osmosis. Surface tension. No, we’re not developing a high school science curriculum! These are just a few of the scientific concepts the experiments below illustrate. Even the smallest kids can participate in these easy, top-rated science experiments for kids. You just may have a budding scientist on your hands!

Bouncy Rubber Egg Experiment

Can you make a raw egg bounce? Turn a raw egg into a bouncy “rubber” egg with just one household ingredient! (Bonus: what happens when you use a smaller egg, or add food coloring? Watch to find out!)

Liquid Density Experiment

This liquid density demonstration (using pantry staples like vegetable oil and corn syrup) will impress children who think of liquids are “all the same.” Let young kids play with jars of colored water first, seeing them mix… then show them this!

Sink or Float Printable Experiment

Sink or Float
Teach children the scientific method–and experiment with buoyancy–with this easy printable! Guess which objects will sink or float…then test your hypotheses! (Kids draw their predictions, so even preschoolers can try.)

DIY Volcano/Elephant Toothpaste Experiment

Get outside and make your own volcano! With just a few household ingredients, create a (safe) explosion that looks like enough toothpaste for an elephant to brush with. (This project requires a grownup’s assistance, but all the items are safe to use.)

Celery and Food Coloring Experiment

Got food coloring and celery? Watch capillary action at work in this classic home experiment!

Salt Water Experiment

A longtime community favorite, this deceptively simple science experiment dramatically demonstrates how fresh water floats on top of salt water.

Surface Tension Experiment

Can mesh keep water from flowing? It can…with the help of surface tension!

Wind Experiment

Can you blow out a candle — with an object in front of it? Try it and see with this quick, fun wind experiment!

What Soda Does To Teeth

Is soda bad for your teeth? This simple-to-set-up experiment provides a clear answer.

Make a Jellyfish in a Bottle

A recent favorite: make a floating “jellyfish” in a bottle to play with!

    I cannot tell how much, of what, to do when, in the Volcano experiment just by watching the YouTube video. Can I get detailed instructions please?

    Thank you!
