In our study of energy, we are investigating sound waves. We have discovered that there are different types of waves, and sound waves are called compression/longitudinal waves.
By playing with a rubber band, we discovered that pitch is connected to frequency: the higher the frequency the higher the pitch.
When we explored compression waves with a slinky we also discovered that the more taut the slinky, the higher the frequency.
Last night's homework was yet another inquiry into sound using glasses filled with different amounts of water. The question I posed to the students was, why do the glasses make a different pitch? What is going on?
