Sound Transfers Energy
Supplies: empty bowl, plastic cling wrap, candy crystals/sprinkles or salt
Steps:
1.
2.
3.
4.
Get into groups or partners and distribute supplies and handouts.
Cut a piece of plastic wrap big enough to cover the top of the bowl.
Secure the plastic wrap is tightly, like a drum.
Next, sprinkle a small pinch of candy crystals/sprinkles or salt in the
center of the plastic.
5. Get close to the bowl, and say your name aloud. Watch the
crystals/sprinkles/salt.
6. Describe to your group what you see happening.
7. Try humming. Describe to your group what you see happening. Try
other ideas.(loud voice, soft voice, soft pitch, singing, high pitch,
whisper, etc)
Explanation:
Sound is created by vibrations. Have your child put his hand on his throat
to feel the vibrations when he talks. These vibrations caused the plastic to
vibrate, too, which made the sugar move.
