Camping solo? With troop or patrol? With Pack? What is the camping site like? This all plays into what I'd recommend. I would suggest finding a way to take a hike, bring jet boil and cook some food on the hike, maybe a sketchpad or something to draw nature, binoculars to go birding or watch the stars, just don't forget a good star wheel (don't use phone app).
Maybe also try something like cooking with nothing cold, so bring all food that needs no cooler. I really want to do this myself to be honest.
I picked this book up from the library this weekend, and it has SO many ideas I want to do on a future pack campout. Maybe if you can find a copy it would have some ideas.
