Make some noise! Hearing is the ability to perceive sound by detecting vibrations. But what is the connection between vibration and sound? We’ll use simple mechanical detectors and various sound-making objects to observe and help define this connection. Then, we’ll learn what makes sounds different from each other by experimenting with variations in vibration, pitch, and frequency. Students will learn how sound waves form, and will construct a simple eardrum to demonstrate how sounds carry. Then, we’ll construct a simple coffee can oscilloscope to observe how light patterns produced by sound energy resemble waves before building a coffee cup speaker that can convert electrical energy from a audio source into sound energy that can be heard!
