Questions for Discussion: Sound and Solids: Listening Stick
What would happen if you replaced the yardstick with string, a straw, and a metal curtain rod? If you could "see" inside the yardstick, what do you think it would look like? Are there any solids that you think won't carry sound well? What about liquids? What could you do to see if liquids carry sound well? Have you had any experiences that might help you with this? What do you know from swimming underwater at a pool or in the ocean or a lake?
