In this activity, students model how sound travels by sending waves along two stretched plastic slinkies tied together.
By the end of this activity, students should be able to:
- understand that sound is a longitudinal wave where particles in the medium vibrate back and forth along the same direction as the wave travels
- see that a wave travels along as a series of compressions and expansions in the medium.
