Sunday School camp-out activities ideas?

I need to come up with a list of events and activities for a small group of Sunday School kids ages 8-15. There will be no more than ten kids present. We are having an overnight camp-out near a lake and there will be events like swimming, volleyball, smore-making, etc, but I need some games and bible-related fun suited to a small group. Any ideas? Please don't respond if you're just going to leave a smart-alec comment. :)
