Letter to mum and dad about sound.

 WALT talk about what we are learning.

I wanted to share with my family what I was learning about sound

To Mum and Dad from Hiku 

I am going to tell you what I have learnt about sound.

The first thing I learnt was that sound is made by vibrations.

If you get a can and a string and put the string on the top of the can the string will vibrate on the can and it will make a sound.

Another fact we learnt is that there is no sound in space.

There is no air and water in space. Sound needs air particles to carry the sound to other particles and then they go into your ear. So that’s why there is no sound in space.

Also we learnt that sound can move objects

like rice and hundreds and thousands. It can make water splash and it can make a ping pong ball jump.
