Sound Sketch Tool

Grade: 6th to 8th, High School

Sound can be measured and quantified in many different ways. Sheet music is one way to represent a series of sounds. MP3 players and computers use a different representation to store a sound. This activity includes software that allows you to sketch and quantify sound using two different representations.

Instructions
