In this free science fair project, learn how to separate salt from water using heat. A great science project for elementary school kids.

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

This activity will help your child review science concepts, learn new ones, and become familiar with examples of various concepts in science. Plus, it's fun!

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.

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