I have vague recollections of helping the elderly, building campfires, and possibly knot tying and camping (putting up tents, etc.) merit badges.
I was a Girl Scout and a Campfire Girl in the US as a child. In both, we stitched our merit badges on sashes that we wore with our uniforms when we attended events. I had to complete a series of badges to move up the ranks in status--though often in these organizations, if you were of a certain age you would automatically "level up" in game speak--even if you hadn't completed the badges from the previous level. Also, completion of the badges before a specific age and you did not automatically graduate to the next level.
As a kid, I remember that the "age override"--if I can call it that--bothered me.
