Facts about Science

Sound is caused by vibrations.

Vibrating objects make sound. This sound is passed to our ears and this is how we hear.

Sounds get louder (increase in volume) when they vibrate harder.

Pitch is how high or low a note is.
The shorter the vibrating object, the higher the pitch.
