Sound Volume

Key Stage 2

Volume is how loud or quiet a sound is.

Sound is caused by vibration and the bigger the vibration, the louder the sound.

The bigger the vibration, the louder the sound.

When you hit a drum hard, it makes a louder sound because the vibration is bigger.	When you pluck a guitar string harder, it makes a louder sound because the vibration is bigger.	Blow harder down a tube it makes a louder sound because the vibration is bigger.
