This energy-burning bone hunt is best set up in a dry sandbox, but a sheet of plastic covered with sand and set in an easily cleaned spot will work as well. Before the meeting, bury twenty to thirty dog-bone biscuits of various sizes, as well as one plastic dinosaur skeleton. Let a couple of bones peek out from the surface to give the boys a head start. Hand out a small plastic pail and shovel to each boy and give them five minutes to dig up as many dinosaur parts as possible (they must use the shovel; no hands allowed!). The boy who finds the most bones gets a prize; the one who finds the dinosaur gets to keep it or gets a special prize
