Make a Guitar

  • A guitar is a STRING INSTRUMENT
  • When you pluck the strings (rubber bands), they VIBRATE and make a sound.

Materials
  • box, pan, or other container without a top
  • 5-6 rubber bands (all different widths)

Directions

  • Begin with the widest rubber band and place it around the box.
  • Then choose the next widest rubber band and place it approximately 1/2 - 1 inch away from the first rubber band.
  • Continue until all the rubber bands are placed around the box.
  • Make a prediction about the pitch of sound (lowness and highness) that you will hear as you pluck each string.
  • Pluck each string (rubber band).
  • Observe the strings vibrate and listen to the sounds.
  • What difference is heard in the pitch of sound when plucking the strings?
  • Try to play a tune with your new guitar.

Explanation: The wider the string the lower the pitch of the sound. The narrower the string the higher the pitch of sound.
