Using an empty tennis ball can and a swimming pool, you will determine if it's possible to have a conversation under water.

This science fair project examines how tsunamis travel by simulating a tsunami moving around an island. You will generate a pretend tsunami in a swimming pool.

The objective of this science fair project idea is to determine if sound travels best through the air, water or a solid.

How fast does light travel in different mediums? Kids conduct a cool refraction experiment in materials like water and air for this science fair project.

This activity is a fun way to "go fishing" with your preschooler, while learning about the concepts of freezing and melting.

Demonstrate how we are able to locate sounds, echolocation. Have a blindfolded subject locate you by the sound of your clapping.

How does rust form? Kids will learn about the roles oxygen, water, and electrons play in rust chemistry in this cool science fair project idea.
