DIY.org is a great initiative that encourages kids to do challenges and gain patches for participating in creative tasks that involve building and craft.
Some of the Skill Patches include the Astronmer, the Camper and the Gamer. There are plenty of patches to obtain and they each have a number of challenges for a child to complete before qualifying. It's a fun concept and something that would have been pretty awesome if it was around when I was kid. To top it off they also have a really catchy anthem. Build. Make. Hack. Grow.
