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.
