Summer Science Experiments for Kids


Summer themed science experiments are a surefire way to make learning fun this summer! While you can do these experiments indoors, one of the best parts about summer science experiments is that you can move the fun, and the mess, outside instead!

Science is all around us, so if you love science like we do, you will definitely want to check out these awesome summer science experiments.

Make Your Own Bouncy Balls

  • ½ Cup Warm Water
  • 1 Tb Borax
  • 1 Tb of Cornstarch
  • 2 Tb White Liquid Glue
  • Food coloring
  How to:
  1. Mix warm water and borax in a bowl.
  2. In another bowl mix the glue, cornstarch, and food coloring.
  3. Pour the glue mixture into the borax mixture.
  4. Wait about 10 seconds, then use a fork to take the glue mix out of the water. If the glue mixture is still sticky, dip it back in the water for a few more second.
  5. Roll the mixture in your hands to make a ball. The more you handle the mixture the firmer it will become. We found that 30 minutes was the perfect amount of time before using. Have fun bouncing your bouncy balls outside!
