10 Fun Balloon Science Activities for Kids

Kids love balloons. Kids love fun science activities. Add them together and you’ve got an afternoon full of fun!

Recently, I found a pack of balloons leftover from a birthday party. Knowing we would use them in the fall for our second grade homeschool curriculum, I placed them with our school things. The only problem? My kids found the balloons. Instead of just blowing them up and letting them play keep-away from each other, I rounded up some ideas to bring a little fun into our afternoon and still sneak in a little science. The list was so good, that I had to share with you!
