Oh, my! What an unfair question to ask! Your teacher would not be pleased to know that you totally abandoned your own responsibility to at least come up with an area of interest! Education.com is not here to do your homework for you but rather to help you if you get stuck or need advice. What you need to do is decide on an area of interest - solar power? metamorphosis? magnetism? whatever, and do a little background research yourself before you ask us for help. Good luck!
