From the children side:

I was a kid and was trained by Duke of edinburgh award, parents, outdoor survival schools and scout association


The best training ground is with your parents and the scout association

If your boys WISH (don't force) top go to scouts find out what they get up and try and get an outdoor based unit!

Buy your boys a small swiss army knife and teach them the correct and safe way to use it-this should be one of your first lessons this is the only time you can "teach" this is because of the dangers of knives and because if they are like any other kid they will be so excited by the knife they won't mind!!

After this show them hoe to use a whistle and the international distress signal! In a fun gamely way!

Play games and make it fun!

Personally i don't believe that morse code is that useful and it CAN quite easily turn into a lesson which is very boring!!!

Keep going back to fires and have little challenges to see who can light fires with minimum matches, smallest amount of tinder etc. And each marshmallows round the fire(most kids love food)

My final note would be - you know YOUR kids the best so YOU know what drives them so you can target and taylor your sessions around this

BUT don't make it boring-if they are not interested give up on the oTHER hand if they ask for MORE feed this!!!

just my thoughts
