What's Your Frequency?

The purpose of this lesson is to introduce and apply the concept of frequency.

Students will begin by a motivating “click the mouse” challenge. This will help them to develop the concept of frequency. They will transfer this concept to a hands-on lab where they will be creative and measure various types of frequencies.

The lesson then transitions to sound waves where students learn about how energy can be transferred through air with a given frequency. They learn how to measure this frequency and then use a cell phone app to record their own sound waves and measure the associated frequencies.

Lastly, a set of problems is provided that allows students to further practice the concepts at hand. This lesson will take between 2-3 class periods. Very few supplies are needed
