Intro-Today I'm going to tell you about why do we hear sounds and how we hear sounds.
Sound waves are vibrations in the ear drum.
sound waves are collected by the outer ear.
sound waves cause the ear drum to vibrate.
The anvil hummer and stir up wobble and move the liquid inside the ear
nerves pick up the liquids movement and send messages to the brain.
The brain makes sense of the nerves messages and helps us to recognise the sounds.
Whats your opinion on why do we hear sounds.
