K-12 schools across the country can now nominate themselves for a green makeover through Ford and Paige Hemmis, a designer from ABC's "Extreme Makeover: Home Edition."  Ford is sponsoring a nationwide contest that will award one lucky K-12 school an eco-friendly makeover worth up to $250,000. Students, parents, community members, staff and teachers are encouraged to nominate a school by submitting an essay online.
