Sound Experiment

February 3rd
We're having more fun experimenting with sound.  Today we were talking about how humans make sound.  We blew up a balloon, which once inflated acted as the lungs, and then we let the air pass through the top, which acted as the vocal cords vibrating.  This was a fun, and LOUD experiment!  Hopefully it will help the students remember the concepts!  Vibration = Sound!
