The NPC website has a link to information about the National Eating Disorders Screening Program. If this isn't already where you got the idea to do this week, then it'd be good to check out, there is a lot of information. I know that my school did this two years ago (maybe more often, I just only heard about it my junior year) so I'll e-mail the girl that was president of PHC then and ask her what all we did and let you know.

ETA: There is contact information on that site - I'd try e-mailing them, they might be able to tell you what they know has been successful/eye opening on other campuses. Good luck!
