In celebration of the 40th anniversary of Earth Day, PBS KIDS GO!’s Design Squad is launching a nationwide 2010 Trash to Treasure competition on April 5th. Kids across the country ages 5-19 are asked to recycle, reuse and re-engineer everyday materials into new inventions. Three young innovators will win a trip to Boston to see their designs built and have the process chronicled for an upcoming episode of the engineering TV series. Above is a video of last year’s winner Max Wallack, 13, inventor of the “Home Dome”–a temporary shelter for homeless people and disaster victims. This seems like a really great contest to get young minds thinking of ways to craftily reuse materials into something beneficial.
