Mark, I present them with a scenario that explains how they ended up in a survival situation and what they have to work with. I add resources as they are figuring out how to solve it one way, so they can try another way. They do get helpful hints and tips on how to do specific tasks. It is not a test, just an exercise for their brains.
I do plan to take the older scouts out soon for a survival exercise with only what is in their survival kits, no ten essentials in a backpack. I will also introduce many of them to going from live animal to prepared meal. That should be interesting for some of them. This campout is intended only as a fun confidence builder.
