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

Science fair project that examines what causes thunder and why a thunderclap sounds so loud. How is lightening related to the creation of sound waves?

This classic children's game demonstrates how sound travels through air vs. through a solid.

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.

Little scientists will make inferences about hearing loss, pitch, and frequency in this great science fair idea that puts the human ear to the test.

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