1. ​Choose some different size rubber bands.

   2. ​Wrap the rubber bands around objects. Create sound by vibrating the rubber bands.

   3. Using your rubber bands, create sounds that are low pitch. What did you do to get low pitch sounds?

   4. Using your rubber bands, create sounds that are high pitch.​ What did you do to get high pitch sounds?

​Thick rubber bands usually create lower pitch sound because the frequency is lower.

​

​Looser rubber bands usually create lower pitch sound because the frequency is lower.

​​Looser Rubber Bands

​

​Tighter rubber bands usually create higher pitch sound because the frequency is higher.

​​Tighter Rubber Bands

​

​Thicker, Looser = Low Pitch

Thinner, Tighter = High Pitch​
