Dividing up into pairs, you will practice being behind and in front of the camera. Having a lens "in your face" can be very disconcerting, and a good photographer should not only be aware of this, but should have skills in putting people at ease in this sometimes awkward situation. Help each other relax. Spend some time getting to know your partner -- sometimes the difference between a mediocre portrait and a great portrait is the difference between taking a shot of a stranger vs. someone you know.
Try out different poses -- different faces need different camera angles to look their best. Practice telling your partner how to turn their head or how to place their hands. See what works best for each person.
Poses to try:Try out different backdrops -- indoors, try standing your partner in window light; outdoors, try the horizon (silhouettes!), etc.
Get this film processed on your own -- if you belong to Costco, they process film quite cheaply in 24 hours. District Photo, also north on Route 1, has a sale on processing for the month of March. Media Express, on campus, as well as other locations in the area also process film.
