In this unit, students start by observing a perplexing phenomenon. When a sewing needle taped to a cone is dragged over the surface of a plastic disc that is spun underneath it, it produces voices and musical notes. This leads students to start wondering about other sound-related phenomena, which in turn leads to wealth of new questions about 1) What causes different sounds? 2) What is traveling from a sound source to our ears? 3) How do we hear and why do we hear things differently in different places? and 4) How do electronic devices (digital sound sources) produce and detect sounds?
