In this 3rd grade science activity, you'll experiment with the little-known fourth state of matter: polymers! Mix borax with white glue and watch what happens.

What's a liquid? What's a solid? What better way to experiment than by turning a childhood favorite, ice cream, into a homemade science lesson!

Get your hands on a concoction that breaks the rules about what's a solid and what's a liquid.

Encourage your child to think outside the bathtub by making her very own handmade soaps! Perfect as a present, a decoration, or just to pamper herself.

Make your own marshmallows and mix up some very interesting third grade chemistry lessons while you're at it!
