Do you realize that this study would have almost no correlation to anything? You're going to need a bigger sample size than just ONE of each race...
It's not really a "study" though. My class consists of about ~30-40 people and each group of 3-4 is supposed to do a little "field activity" or whatever you want to call it (it's not an experiment, even). We're then going to share "results" (again, not really "results" but more like "experiences") with the rest of the class as part of a discussion, etc. No one's out to really PROVE anything. It's not a big paper, project, study or anything, just a small immersive activity.
