What I learnt in sound
In class 5 we were doing science experiments about sound. The experiment was called making sound it is the picture down the bottom.
When you hear sound it can be very loud our quiet. You
can almost here sound every were around the world.
When yell in a cave the sound reflects of the walls and back at your ear's. When you yell out side the sound doe's not reflect of any thing and back at you.
