Following our fabulous week on sound last week here is the link which shows you how to make a sound sandwich like we did in class.

Once you’ve shown off your sound sandwich explain how it works and what changes the pitch.  You might even try to see how else you can change the sound it makes or its pitch e.g. by changing the thickness of the rubber band which vibrates.
