Hi! I am in Grade 11 in high school, and we have this big project coming up which is called Extended essay. Basically, it is a research essay 3000-4000 words, and I chose to do mine in physics. The thing is I have trouble finalizing my topic. I decided to do something in acoustics, such as looking at noise-canceling headphones, or using waves in suspension as Bose did http://www.bose.com/controller?even...arning/project_sound/suspension_challenge.jsp. However, I am not really sure, what should I be doing with it, and how should I plan my experiment. Thanks for any help.
