These simple, DIY science experiments for kids will help combat “summer slide” — and your kids will be having so much fun, they won’t even notice that their brains are getting a workout.
The best part about these experiments? All the ingredients and tools used can be found in the pantry, fridge or bathroom (or, at least, at the grocery store).
Beat the heat this summer with these 12 unique science experiments for kids! Follow the links for exact instructions.
Science experiments for preschoolers
Try the soap & pepper experiment
A classic one for the kids: a little bit of pepper and water in a shallow bowl and one finger dipped in some liquid soap teaches kids the importance of washing their hands. A cotton swab with liquid soap works just as well, too!

Watch some rainfall in a cup using some shaving cream, water and food coloring! Use different colors for some unique rainfall.
Make bouncy bubbles
Fulfill every kid’s dream to touch soap bubbles with this easy craft! Plus, this craft only uses three ingredients you have at home.
Science experiments for elementary age kids
Make a walking rainbow
This experiment visualizes the science behind primary and secondary colors and the rainbow. Plus, the experiment only requires some food coloring, cups, water and paper towels!
Make a DIY water xylophone
Add different amounts of water to multiple cups of the same size with no lid and tap them with a spoon to hear different tones. For a challenge, try to make a song out of the new instrument!

Watch gummy bears grow
Gummy bears soaked in water help them expand double in size! For a complete lab experiment, try soaking gummy bears in different types of liquids, like saltwater or your favorite soda.
Science experiments for tweens
Learn why sunscreen is important
With some colored construction paper, sunscreen and paper plates, kids can see just how important it is to apply sunscreen all throughout the summer. For more interesting results, consider using cream and spray sunscreen on different pieces of paper, and watch the difference in protection.
See an egg shell disappear
With the help of science and a little bit of patience, see in real-time how an egg shell can disappear!
Make a lava lamp
