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.

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