Letter to my mum and dad.

WALT talk about what we are learning.I wanted to share with my family what I was learning about sound.

Dear Mum and Dad.

Dear Mum and Dad in my class I am learning about sound.

Sound has power because when you make a loud sound the hundreds and thousands move.

Sound is energy. When you make a noise it vibrates.

A tuning fork has vibration in it because when you hit it, it feels like a little buzz.

When you make a noise it vibrates and the particles make more and more with the sound so it goes all the way to your ear and through the eardrum. 

I think sound is made with power because when you hit the tuning fork and you put it on the ping pong ball it moves by itself.

The noise travels with air waves, particles and vibrations.

When you blow into a hole in the middle it will make a sound but when you block the other side it makes a different sound.

When you make a noise it vibrates and the sound goes to the particles that make more and more to get to your ears and it goes to our eardrum and through the three bones in our ear and then it goes to the cochlea with the liquid inside.

When you hit the tuning fork and put it in the water it makes the water splash.
