Pinhole projects for schools?

I'm interested in doing a pinhole project with my daughter's elementary school class. Could someone point me toward a resource that might help? I'm thinking cereal box cameras and 8x10 lith film with solar printing on POP, but maybe there is an easier way to go. I have no idea if you can buy POP or what it costs.... There is a small bathroom in their classroom that we could rig up as a darkroom temporarily.

Thanks,

Will

Will,
You might consider blueprint "sun prints" instead of POP. "Develops" in water. You can sometimes find kits in kid-oriented science catalogs. You might also be able to purchase the materials at a commercial blue-print duplicating place. Cheap, easy, non-toxic.

I'd suggest going with paper negatives. There's a host of information on the f295 forum (f295.tompersinger.com) and on pinholeday.org Or, if you're intent on lith negs, perhaps try cyanotypes. You could precoat a bunch of paper easily enough, and the rinse is only water.
