Welcome to the forum and to scouting brian, I hope you find both worthwhile...
In teh past ive done all sorts of basics with my cubs, tracking, firelighting, shelter building (both full sized and mini hedgehog shelters, which can be good for shorter time frames, navigation, backwoods cooking (cooking without using utensils), knots, tree/plant recognition, camp gadgets.
What to pack for camp is good for a night in the run up, we use a short skirt with a leader acting as a cub, complete with a huge wheely case, cup hanging of it on a piece of string, Akela goes through the kit list and it turns out the cub has nothing on it, when the case is iopened theres a huge teddy bear in it... that raiseis another importnat point, particularly with cubs, if you use a teddy at home then feel free to take it, i have a tiny one thats always in my rucksack so if anyone laughs at a child for haing a teddy i can show them ive got mine too.. this takes 5 minutes but leads into a talk and gme on what to pac and how to pack it..
enjoy yr time with the kids, its when you see them as adults years later you realise how important what you do now is.
