Sound Waves

We cannot see sound.

We can hear sound!

What is sound?

Sound is made of waves.

Sound waves are like waves in the ocean.

Sound waves are made of air.

Hit a drum with a stick.

The drum moves back and forth.

This is called to vibrate.

The vibration makes the air move.

The vibration makes the air move in waves.

These waves are called sound waves!

Sound waves make the sounds we hear!
