Even if youve put together a great experiment with sound results, you need to make sure that it looks professional if youre going to present it in a competition. Question to ask: What does the length of the straw have to do with the pitch of the sound we hear? (Students interested in exploring noise levels further can experiment using the Extreme Sounds: Lessons in a Noisy World project. The faster something vibrates the higher the pitch. If you measure a whisper, youll get between 20 and 30 dB. (It is only when those waves are turned into electrical signals and interpreted by our brains that the sound has meaning!) If there is no medium for a sound wave to travel through, what happens to the sound? The sounds we hear voices, music, birds chirping, dogs barking are all caused by vibrations. Students explore by creating a vacuum to simulate conditions in outer space and then use a sensor-based phone app to measure the sound intensity of a buzzer. This work has appeared as the basis for many subsequent hydrophone build activities and offered one of, if not the first activity of this nature. The addition of the ruler helps them to understand how a dampener works to affect pitch. In the lesson, students use what they learn about absorbing sound to build sound-insulating containers big enough to hold a phone. When it comes to science experiments, some of the most enjoyable involve the science of sound. You should notice that the longer the bar, the lower the pitch. This science of sound experiment makes sound more visible by forcing objects to react to the sound vibrations.
