I am learning to talk about my ideas.
I wanted to share my ideas about sound with my family.
Dear Nan and Dad.
We have been learning about sound.
Did you know that there are particles all around
us and you can’t see the particles.
Sound is made by vibrations. The vibrations make the particles in the air move. This makes sound waves that take the sound to your ear.
If you put a tuning fork that is vibrating next to a Ping pong ball, it can bounce. If you put sprinkles on top of a glad wrap bowl and you make a loud sound, the sprinkles jump. This happens because the vibrations make things move.
There is no air in space. The astronauts have to take air with them. If they did not take air with them, they would not be able to breathe. In space there is no air and no sound. Sound needs air to move
