Sound

Physics of Sound
==This unit consists of four sequential investigations, each designed to expose a specific set of concepts. Students learn to discriminate between sounds generated by dropped objects; how sounds can be made louder or softer and higher or lower; how sounds travel through a variety of materials; and how sounds get from a source to a receiver. The investigations provide opportunities for students to explore the natural and humanmade worlds by observing and manipulating materials in focused settings using simple tools. ==
