Sound Assessment

This is my sound assessment. It shows what I knew before and after.

How we hear sound

How you can hear sound.Sound waves go thou the ear canal and vibrates the eardrum, goes through the ossicles, then the cochlea and then it goes to the brain.

Exploring sound

 Our topic for term 2 is sound.

I already know;

1. planes motors are 120 decibals
2. leaves rustling is 10 decibals
3. the sound barriers faster than me talking to you  and you hearing me.

That's all I know. What do you know?
