What's Shaking?

What you need:

• small plastic bottles
• funnel
• variety of noise-making materials, including aquarium gravel, dried beans, dried pasta, rice, sand, Styrofoam peanuts, and small bells
• masking tape or glue

What to do:

1. Collect empty plastic bottles. Remove the caps and allow the bottles to air dry before replacing the caps.
2. Put the different types of materials into small plastic cups or bowls.
3. Choose two materials that vary in size and place them into bottles, putting enough inside so the material can shake around. Secure the bottle caps with masking tape.
4. Take turns shaking the bottles. Which sound is the quietest and which is the loudest?
5. Use the sound bottles as instruments while listening to recorded music, or while dancing or marching to music.
