According to the Children and Nature Network, only 6 percent of children ages 9-13 play outside on their own in a typical week. The National Children's Museum aims to change that. While the 2012 opening focuses on indoor discovery, an outdoor experience is in the works. With a space slotted in the next block over, the museum's outdoor area will be one of the country's largest.
Solar panels, "pinwheel" generators and a hands-on family garden will educate families about energy conservation and food. Play areas, fort-building and climbable peaks get wee ones moving. Finally, a large amphitheater will provide a place for kids to watch theater and produce their own.
