Exploring sound waves

In science we have been testing how sound waves can move stuff. We used tuning forks to create vibrations. We tested the vibrations three times using salt and three times using water. The first four pictures show us using the tuning forks to vibrate salt that was on saran wrap stretched around our yogourt containers. The last four pictures show us using the tuning forks with the yogourt containers filled up with water.
Everyone liked the experiment and most people were surprised by how much the vibrations can move the salt and water.
