What children learn in Level 40

Be a sound detective! When you hear a sound, look and feel for the clue: something is vibrating.
A bee buzzes. Its wings move so fast they look blurry. The vibrating wings make the buzz!
Touch a ringing bell, and the sound stops. Your hand stopped the vibration. That's more evidence!
Try it with a grown-up: stretch a rubber band and pluck it. Watch it vibrate and listen. Then hold it still.
Your turn! Put the rubber band test in order.

Georgia Standards of Excellence in Science:

S1P1.d — Construct an explanation supported by evidence that vibrating materials can make sound and that sound can make materials vibrate.
