Building on jmoore and Warpig's comments, teach them what to look for in the animal's reaction after the shot. Sorta gruesome, but it'll help them to stay the fever...maybe...
- humped rear end showing gut shot (better sit tight for at least an hour, in any weather except a snow storm)
- color/consistency of blood at the point of impact
- tail up or down?
- some rudimentary tracking and box search. Carry TP and/or survey tape!
All those came out of my bowhunting hunter ed course, in about 1985ish.
Good luck, and thanks for teaching the next generation!
