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.

The goal of this science fair project is to assess the acidity levels of common food and household products using pH test strips.

This easy Halloween-themed science experiment for first-graders is perfect for chilly October afternoons or great as a Halloween party activity.

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

Bring back the groovy memories by making shrinky dinks using household materials, while learning about the science of plastics. Here's how to get started:

Do this experiment to help your first grader understand how salt can be removed from salt water. All it takes are a few household materials.

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.
