At the campsite we go to we have a really nice nature center. A few years ago a troop revamped the nature center to get their silver award. The nature center is filled with activities for the girls to do. One of their favorites was camping bingo. The sheets were printed out and placed in plastic covers so they could be reused again. There was a big bin of scrap pieces of paper cut into squares that were to be used to cover you square. The girls really liked this game and it can be used over and over for anyone who comes to the nature center.
