This week we were visited by four Pacific students who taught us about sound waves and pitch. We felt vibrations of sound waves on a drum, a guitar, and on our own neck. The students introduced us to instruments called Boomwhackers. Each one was a different color, different length, and produced a different pitch. We hypothesized why each one made a different sound. Many of us decided that the pitch produced by each Boomwhacker was dependent on the length or distance the sound waves had to travel.
Each of us got to play a Boomwhacker during a group presentation of Twinkle, Twinkle Little Star. When we all played together we were able to hear the different pitches within the song. We ended the activity by writing why we love music and taking a group picture. It was a very fun experience!
