Grade:

Teacher:
Debbie Brooks

It it interesting that you when you are underwater you hear sounds made outside the water. How do liquids affect how sound travels? Does the thickness of a liquid affect how sound travels? This project found that liquids increase the volume of sounds traveling through them and it was most affected by thicker liquids.
