This simple sound experiment from San Francisco's Exploratorium lets your students experiment with sound—without making a lot of noise. Each student will need a piece of string or yarn that’s at least 3 feet (1 meter) long. Students can work on their own, but we suggest students work in pairs so they can discuss their ideas with one another.
Follow the instructions here. Encourage students to experiment to figure out how to change the sound. (They can make it higher by pulling the string tighter and lower by loosening the string.)
