What are some good science research topic questions?

I been looking for a research topic question or awhile and the ones I wanted were taken. So I guess I'm open to any research topic questions that is science related.

The best research topic question will receive points. ^_^

Answer 1

The question does not state at what level in science you are.  That is, are you in 6th grade, 9th grade, 12th grade, a college undergraduate or a graduate student working on a PhD.

I suspect that you are not a graduate student or even a college student.  You would have been much more specific.  I think that you are at the other end of the range.  

Nevertheless, I'll give you a general topic:  mass extinction.  

It will work for students at all levels of education.
