ENERGY
Energy is something that can power something like a car. Energy travels in a back and forth motion like a slinky. Sound travels more close to gather when it’s higher pitched. What helped me to Ander stand? 1 watching videos 2 looking at the slinky the way it moves like a sound wave. 3 tapping a table with salt on top. 1 can heat change the sound?

James, you have quite a bit of knowledge about sound. Have you looked at it before? It is a good question about if heat can change sound? You should look into it. I know sound travels at different speeds in different heats so I'm not sure if it changes the sound quality.
