Vibrant Cords

In this activity, learners will explore how the voice works and feel the vibrations produced by vocal cords. They will learn that the vocal cords are made out of the material elastin, and will experience the variety of pitches produced when vocal cords are stretched and relaxed. As an extension, you can use a stringed instrument of some sort to demonstrate what happens when the vocal cords are tensed and relaxed.
