Discovery Sound Stations

In science today we completed five stations to discover more hands-on about how sound works and to see in action what we have read about the past couple of days.  The main things students needed to learn from our work is that sound is heard because of vibrations and that the larger the object used to create the sounds, the deeper the pitch, and the smaller the object, the higher the pitch will be.  We used chimes, glasses filled with different amounts of water, and sound fork and spoon, and rubber bands stretched over a board to create different pitches.
