Kids will conduct a cool limewater carbon dioxide test that can be performed with common household materials to learn about the chemistry of this common gas.

Try this experiment to give your curious kid a more "solid" understanding of how temperature affects the states of matter.

Is it solid or liquid? Create oobleck and witness the amazingly weird oscillation between the two!

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.

First grade science often covers solids, liquids, and gases. This silly science explores serious facts about the difference between all three.
