Basically the extended essay is a piece of independent research done during the course of IB. I'm planning to do a physics EE, but now it's mid April and I still failed to find a simple yet specific topic to do reasearch on. My last few ideas were too complex or not specific enough. My imagination's failing me at this point, and I'm starting to fall behind for my EE. Can anyone suggest a topic which I can complete with a simple experiment, yet is not too hard for a high school student to complete in 5 months?
