Tuesday: Sound is shaking

Rocket plucks a rubber band on a box. Twang!

Raven asks, "What do you notice about the band?"

Nova whispers, "Look closely while it sings."

Shake, shake, sound!

Things make sound when they vibrate.

Vibrate means shake back and forth very fast.

The rubber band shakes back and forth.

The shaking pushes on the air.

The air carries the sound to your ears.

Your voice vibrates too

Put your hand gently on the front of your neck.

Now hum a long hum.

Air from your lungs makes parts in your throat vibrate.

That buzz is your voice!

Big shakes, little shakes

Bigger vibrations make louder sounds.

Smaller vibrations make softer sounds.
