I would keep it simple. First, a short dissertation on the camera, what it is capable of, what you must do, differences between what their small format does for them that they must do for themselves.
Second, a trip to the darkroom for a tutorial on film handling. Here I would stress the importance of cleanliness, which starts with clean hands (far too many times I've seen comments regarding fingerprints on film). Loading and unloading film holders(using dummy film in daylight). Follow with lights out, time for the real thing. I would limit each student with only one holder(two exposures).
Time for an outing. I don't recommend studio still life, rather (weather permitting) landscapes. I see no need to overwhelm neophytes with more complex set ups(save for another class).
Back to the darkroom, unload and develop. End of day one
Second day, revue of day one. Inspect negatives, printing and proper clean up. I think that the class is limited on how much time each gets with only two enlargers.
Return to the studio to assess the final prints, possible matting and display.
This requires much planning and preparation and an itinerary provided for the class. The OP has stated there are four cameras, that would limit the class to four students. I would only add students IF there is anyone who has their own camera, and just wants to learn how to use it. Bear in mind, this would require more darkroom time on day two.
