Boston Children's Museum's "My Sky" Exhibit

BOSTON - JULY 30: Sean Sevigny, 3, from Wallingford, CT, interacts with the Boston Children's Museum's "My Sky" exhibit. The project is a joint effort between the museum and NASA, and includes at least three major areas: a skate park, which kids can trace the movement of the sun overhead in a matter of second; a child's room with a loft bed, under which will be a series of constellations to identify; and a backyard camping scene, where kids can check out a 5-foot diameter model of the moon.
