You may have a broad topic idea when you walk into class today - and it may be as broad as
'barton springs'
and that's ok. Choosing a topic is part of the research process. You're coming up with an IDEA which you then do some SEARCHing around and then you REFORMULATE your idea based upon what you have learned. You may go through this cycle a few times in different resources before you settle in on a topic you want to write about.
