I work with a camp and tomorrow we are going on a field trip to a farm, we go there every monday and wednesday. Well my group is canoeing and they are having a little race in the water, as so while the kids are in the water some of them will be on shore and I need some ideas on what to do with them, its like a little woods area with a picnick table and a couple chairs. I think I should bring a ball for silent speedball. They wouldnt be there that long so I cant wonder off, they would be waiting about 15 minutes, but they are little and they get bored quick. Any ideas. Thankyou for your help.
