How do different medium affect sound?
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.
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 .
Describe what your experiment showed? You may need to include a link to a spreadsheet where you recorded your tallies/results.
The wool was the best for the cup phones because we could hear each other clearly
