Bouncy Balls - Show the noise levels in your classroom in a visual way

Web Address: https://bouncyballs.org/

About: This is a great site for when you want to control the noise levels in your class room.  In order for it to work you need a microphone plugged into your class computer and then have the display of the class computer projected onto a screen/interactive whiteboard.

The louder your pupils are, the more the balls bounce...
