This science fair project creates a visual model of whatâs happening to sound waves as a car approaches and then leaves.

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

Find a mathematical relationship between the intensity of a sound wave and distance from the sound source. Use a pedometer and a sound level meter.

.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.
