~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In their study of sound, the students investigate different ways of making different types of sound. One method was the "Bullroarer", a simple device that creates a "rurring" sound when spun through the air. Their task was to investigate the device, then modify it in some way so as to improve the sound created (as in, make it louder, change the pitch, etc.). Here are pictures of the students doing their initial investigations.

Ian_Scott.JPG (41533 bytes)

~~~~~ Bullroarer Modifications ~~~~~

The next day, the students were to bring their bullroarers back, with some sort of modification to make them louder, or have a higher or lower pitch. Unfortunately, most of the modifications produced sounds very similar to the original. I've included the most unique (or humorous) ones here. Thank you to those who took these pictures! (Let's see... Nic, Rachel, Shayna...and one or two more!)
