Hello. I need to make a sound-related experiment on my physics class for a project. Do you have any interesting ideas? There's plenty of various equipemnt in my school that may be necessary.

You could try that, but I don't know how viable it is without knowing more about your school.

Or you could try soundproofing your class with egg boxes and then detail the principle of how it works. Failing that, just a classic string vibration to prove one of the early scientist's work.
