Blowing across the top of a partially-filled bottle can produce an eerie noise, maybe even something that sounds like a steamship. Ultimately, the magnets cause the paper plate to vibrate, which creates sound waves that travel to our ears. The sticks and straws harmonica doesn't get played quite the same way a real harmonica does, but through a series of experiments with the straws and the construction, students will see that the sound the harmonica makes is due to the vibration of a rubber band. In the first activity, students communicate information to one another using vocalizations and their bodies, but not words. For more information about Nancy Larson Science, visit their website or check out the following blog posts. Finally, take the last piece of straw and place it in the harmonica between the sticks on the opposite end from the other, but this piece should be fit above the wide rubber band instead of below it.
