Sound Wave Experiments

Students observe that sound waves travel through the air as a physicl force.  A piece of paper with
rice on it is place a few inches above the bass marimaba bar.  When the bar is struck sound waves
travel through the air, hits the paper which causes the rice to move.  Students vary the distance of the
to see various results.
