K, If speed is the issue, then by all means pre mix it and possibly break up
the solutions into several smaller containers for break out groups. You can
bring a small quantity of the chemicals to show them how easy it is to mix,
and then go through the process of coating. Show your pre exposed paper and
process it, then let them have fun. That's how I did it with 1st- 3rd
graders. They all didn't get to coat as I only had 50 minutes to show them
the ideas and make some sun exposures.

The inaccurate part about tsp, tbsp, cups, etc of dry is in the
interpretation of good measure. There is a lot that can be done with the
good ol' eye balling it and that's great. I find that the biggest log jam
will be on the wet side and not the dry side of the experience. Although it
sounds like you'll be using some negs, so have plenty of contact set-ups
ready. Have fun!
