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  

Did you know that sound is energy. It can make rice jump.         

When you hit a tuning fork on the table it makes vibrations.

When you dip a vibrating tuning  fork into water, the vibrations make the water splash.

Also when you make a tuning fork vibrate it makes a sound. 

When you make an object vibrate it makes a sound. 

Sound travels by vibrations that move air particles. The air particles bump into each other and that makes sound waves that take the sound to your ear.

The sound goes down the tunnel to your eardrum to your bones to the cochlea and the cochlea sends the sound message to your brain.
