Sound Waves Can Make Matter Vibrate.

[CER] DISCUSSION QUESTION:
Does sound make materials vibrate? Or, do vibrating materials make sounds? Make a claim then gather evidence to support and justify your claim throughout this lesson. |
/ Ii / INvestigate
1. Telephone - investigate sound waves with cups and various types of string.
2. Tuning Forks - investigate how different tuning forks vibrate matter. 3. School Musical - investigate various instruments to provide evidence that vibrating materials create sounds and sounds vibrate materials. 4. Speaker Feature - investigate how a speaker vibrates materials on paper. 5. Pitch Perfect - use pitch to investigate whether vibrating materials make sounds or if sound makes materials vibrate. |
/ Iii / Level Up!
During this lesson you will learn more about the characteristic properties and behaviors of waves including:
- Waves, which are regular patterns of motion, can be made in water by disturbing the surface.
- When waves move across the surface of deep water, the water goes up and down in place; it does not move in the direction of the wave—observe, for example, a bobbing cork or seabird—except when the water meets the beach.
- Sound can make matter vibrate, and vibrating matter can make sound.

ADVANCED [+4 points] A student wanted to know if sound can move objects. He used cling wrap, a rubber band, a bowl, rice, and a music speaker. Check out the video and discuss whether or not this investigation provides evidence that vibrating materials can make sounds or that sounds can make materials vibrate. |

MASTER [+6 points]
Plan and conduct your own investigation to provide evidence that vibrating materials can make sounds using the expert criteria below:

/ v / Knowledge Check
A tuning fork is a small, metal instrument with two prongs that form a U shape. It's typically made of steel or another metal that can produce a clear, consistent tone when struck. Tuning forks are used to produce a specific pitch or frequency, which is helpful for tuning musical instruments or testing hearing.
Musicians use tuning forks to help them tune their instruments. For example, if they want to make sure a guitar string is playing the right note, they can strike the tuning fork to produce the correct pitch. Then, they listen carefully to match the sound of their guitar string to the sound of the tuning fork.
Several students wanted to investigate sound waves so they struck a tuning fork and held it near a cup of water.
