Kids say the darnedest things - and sometimes they come up with the darnedest ideas for saving the earth.

Some local heavy hitters, including Wawa and NBC 10, are teaming up to encourage green initiatives at the area's middle schools and high schools through the fourth annual Environmental Community Service Award.

The prize honors student projects that simultaneously save the earth and help the community, like the Penn Alexander School's initiative to revive 4.3 acres in University City as an urban arboretum—one of last year's award winners.

One winning middle school and one winning high school will receive $5,000 (that's $5,000 apiece) to support their environmental programs. The deadline for applications is February 20, and the 2009 winner will be announced on Earth Day.

Applications are online at the site of the Philly environmental law firm Manko, Gold, Katcher & Fox, another award sponsor.
