.Have you ever had problems with your wifi signal strength? In this experiment you will learn about how wireless signals pass through the air and solid objects.

Observe how your brain works while it is focused on one thing, and how it works while you are distracted by another thing.

Check out this fun science fair project idea to learn about seismic waves and how fast they travel during an earthquake.

Determine the relationship between the speed of a sound and the temperature of the air it passes through.

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

This science fair project idea produces sounds by creating vibrations using different objects.

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

This experiment will explore how mallets of various materials and weight create sonic tones of varying lengths.

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

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

This science fair project idea produces varying pitches of sound.

What is the Doppler Effect, or the Doppler Shift? The purpose of this science fair project is to determine how distance impacts the Doppler Effect.
