Draw and identify wave patterns with varying wave characteristics such as different frequencies and amplitudes.
Describe how wave characteristics such as frequency and amplitude correspond to sound pitch and sound volume.
Understand how to generate high/low pitch notes with varying volumes using a string instrument.
We are surrounded by sounds every day, ranging from unpleasant ones like traffic noise to enjoyable ones like music or singing birds. What makes these sounds different? Why are some louder or higher pitched than others? In this lesson plan, your students will investigate how the properties of a sound wave, like frequency and amplitude, affect the sounds we hear. They will do this using Google's Science Journal app and a homemade musical instrument—a rubber band guitar!
