The goal of this science fair project is to evaluate the effect of heat on sound wave frequency.

.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.

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.

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

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