Sound Waves!

Today we looked at the Youtube video on how to see Sound Waves. Normally we can't see sound waves because they are invisible. You can hear sound waves but not see them.

How Does the Experiment Work?

The rice moves and jumps around because of the sound waves that are

caused when the spoon hits the pan. These sound waves travel through the

air and when then reach the plastic wrap it vibrates causing the rice

to move. The sound waves are also what allow us to hear the noise of the

spoon hitting the pan.
