Good Vibrations:
Sound Energy
We spent a week learning a lot about sound energy!
We learned that sound is created through vibrations, and that different sound wavelengths produce different sounds.
For example, longer wavelengths produce low-pitches, and shorter wavelengths produce high-pitches.
We made our own rubber band guitars in class to demonstrate this!
We watched vibrations of sound interact with water by striking tuning forks on our shoes and putting them in bowls of water. Watch the slo-mo video below! (The video works best on a mobile browser).
We watched this YouTube video, taken from the inside of a guitar.
Lastly, we made our own duck calls out of straws!
