After exploring instruments and seeing that they all produced sound with some sort of back and forth "springy" motion, this got us thinking about whether everything that produces a sound is springy, too!
So with Mrs. Brinza's help, we set up an experiment to gather more evidence about this, since the class wasn't in agreement. We also made a slow-motion video of the light to see if it really moved (as caused by the movement of the table). Check out the video below.

We've still got some questions about these vibrations as they relate to louder and softer sounds, and many students are asking for some better sort of "collection of the vibration" with either a better zoom-in or some sort of app to see the difference in these vibrations. Stay tuned!
