Here are some first graders, learning how a musician produces sound from a flute. We don't have a flute but we do have fine collection of baby Coke bottles! We used them to blow air across the top to make a sound, which is very much the same way a flute player produces the sound. (Don't worry, bottles were sanitized in the dishwasher before and after; each student had his or her own bottle.) We also experimented with pitch. We discovered that if we added water, the pitch would be higher. Not only that, but the more water we added, the higher the pitch sounded.
Sixth graders dove a little deeper and we discussed the acoustics of sound. We talked about vibration, frequency, amplitude -- all that fun scientific stuff. The students in these pictures are experimenting with boomwackers of various sizes. They were successfully able to choose which boomwackers would be the lowest or highest, loudest and softest, just by looking at them.
