Who knew snow could be so heavy? Not the Minnesota Vikings, who had to move their football game to Detroit after a Dec. 12 blizzard collapsed the Metrodome's inflatable roof. Snow also makes a dandy insulator that can help keep homes--even igloos--warm and save energy. Have your budding building engineers weigh the merits of various insulators. See if any pick snow!

One way both to save energy and curb climate change is to make surfaces - roofs, even streets - a light color. Solar radiation would be reflected into space rather than absorbed by buildings and pavement. The Atlantic island of Bermuda has been whitewashing its roofs for centuries; they're used to collect rainwater.
