cup phones

TITLE

1. QUESTION/OBSERVATIONS

How do different medium affect sound?

2. HYPOTHESIS

I predicted that it will not affect the sound because it is just the length not like a tunnel where the sound changes weather it is long or short.

3. EXPERIMENT

For this experiment we need 2 cups , String , ribbon , nylon , thick wool thin wool , toothpick , ruler ,  Tape measure ,

Process/Method: 1. get 2 cups put a hole through the bottom on the middle. 2. Measure your medium (string . . . ) so they are the same length. 3. Attach the medium to the cup with the toothpick .

4. RESULTS

Describe what your experiment showed? You may need to include a link to a spreadsheet  where you recorded your tallies/results.

5. CONCLUSION:

The wool was the best for the cup phones because we could hear each other clearly
