I'm in 8th grade and this year, my science teacher is having my class participate in our science fair (duh) and he wants to come up with some ideas and I chose to do something involving the guitar. It must have the scientific method (question, hypothesis, experiment, etc) and involve a constant, independent, and dependent variable as well. One of the ideas I have is "How does the design of a guitar body affect its tone?" and I am looking for some more ideas to consider for the project. I am supposed to have the list of ideas sent to my teacher by Thursday. Please don't send an idea my way that involves soldering because A) I don't know how to solder and B) I do not want to risk making any real damage to my guitar. It CANNOT be an explanation as to how something (like a truss rod, for example) works or why it works. It has to be something that I can research, hypothesize, and experiment on my own.
