Exploration activity 1. Making sprinkles move without touching them
PS4.A: Wave Properties – Sound can make matter vibrate, and vibrating matter can make sound. (1-PS4-1)
By the end of this lesson, the student should able to:
Prepare a slinky before lesson:
“What did you feel as you touched your throat?” (“The throat vibrates.”)
“How is sound produced?” (Sound is produced when objects vibrate.)
Slinky demonstration:
“What did you observe?”
“Do the two ends of the slinky move toward each other?”
“What is moving from one end of the slinky to the other?”
Station 1:
Station 2:
Station 1: Vibrate with the tuning fork
Make a prediction on what will happen if you hit the tuning fork?
What happens if you lower the tuning fork into a container of water?
Station 2: DIY Kazoo
What happens when you hit the tuning fork?
What happens when you lower the tuning fork into the container of water?
What causes the water to splash?
How is the sound made from the kazoo?
What produced the buzzing sounds?
“Where do sound waves travel?” (“Sound waves travel through air, water, or solid objects as vibrations.”)
“What happens when the sound waves hit the bowl?” (“The bowl vibrates.”)
“What happens as the bowl vibrates?” (“It makes the sprinkles move.”)
