In this classroom activity, students will discover that when objects vibrate a sound is produced. Students will first observe different sound sources such as a music box, a sucker toy that has a stick coming out of it, etc. They will then list their observations and come up with an answer to the question "How is sound made?" Groups will then come up with ways to test their conclusion to how sound is made and share with the class. As a class, we will conclude that vibrations cause sound and that a sound source is an object that is vibrating and a sound receiver is what detects sound vibrations.
