Baden Powell always said that one of the most interesting things you can do is explore the world. You don't even have to travel to a far country. Baden Powell taught us that the best and easiest way to explore is to keep our eyes and ears open and notice what's going on around us. If you are interested in learning about nature, here's a good place to start. Black Star Activities will introduce Cubs to the natural world and how it works.
Black Star activities develop a Cub's knowledge and skills of the natural world and understanding how it works. 
To earn the Black Star, choose and do any five (5) of the A Requirements and any two (2) of the B Requirements. These activities can be done by yourself, or with your six, pack, family or friends.
