I think that the third question is a little too broad.. Maybe say how have Iphones and Androids changed society because of the crisis on which cell phone is better. This would cause both crowds with the Iphone and the ones with the Androids to become interested in your topic.

I'm going to have to agree with Austin on this one, I feel like your last two topics are way too broad. The first one is probably going to be your best bet. I know Ali and I just studied Schizophrenia in Psychology 1000 so there are many resources you could use on campus to just email and ask questions. Those would be good primary sources.
