Possible Controversial Science Topics?

What are any science topics? Like cell structure or anything like that?

• In my science class I am allowed to do extra credit all year long on any science topics, even though I already am doing very good in this class, I still want some extra credit, so are there any science topics you can think of? My mind is blank.
