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

In this physics project, learn about the relationship between light intensity and distance using a laser pointer, flashlight, and graph paper!

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 idea produces sounds by creating vibrations using different objects.

This science fair project demonstrates the principles of reflection through simple experiments involving mirrors and light.
