5. What makes sound
Compression- the part of a sound wave where molecules are crowded together.
Rarefaction- the part of the sound wave where molecules are spread apart.

6. What can sound go through
Solids- Sounds can go through solids. To test this put your ear on a table and have someone tap the other end of it. You should hear the tap.
Liquids-you can hear sounds in liquids too. One way to test this is to go in a pool underwater and have someone call you from the surface. You should hear them.
Gases- you can definitely hear sounds in gases! The sound waves hit your ear and make part of your ear vibrate. Air is a mixture of gases so sounds can travel through gases.
