A big drum goes "boom" and makes a low sound, and a small bell goes "ting" and makes a high sound, so big things often sound low and small things often sound high. Then the same drum is tapped gently for a soft sound and hit hard for a loud one, with each sound drawn as a wave, to show that a sound depends on what makes it, and how.

What the lesson says

Why are sounds so different from each other?

Hit a big drum. It goes boom!

The big drum makes a low sound.

Ring a small bell. It goes ting!

The small bell makes a high sound.

Big things often sound low. Small things often sound high.

Now tap a drum gently. Tap, tap.

A gentle tap makes a soft sound.

Now hit the drum hard. Bang!

A hard hit makes a loud sound.

The harder you hit, the louder the sound.

So a sound depends on what makes it, and how.
