Homemade Tunes
In unit two of my junior STEAM class "Light, Sound, & Time," we spent the past couple of weeks learning about sound. We learned the anatomy of the human ear and how it perceives sound. We learned about the speed of sound, reflection and refraction, soundwaves, frequency, and wavelength. We learned about the Doppler effect and musical instruments. For our action project at the end of the unit, we had to make a one-string guitar or Diddley Bow out of common materials. CH. "Diddley Bow." 2021. The Diddley Bow creates sound through the one guitar string. This guitar string is pulled tight between two nails that are mounted on a piece of wood. At one end of the string, there is a dead battery wedged underneath the string to create tension. The other end of the string runs through a soup can, this also creates tension. The tension allows the string to vibrate. The soup can then amplifies those vibrations the same way a soundhole does on a guitar. This creates the so...
