The Classroom Energy Diet Challenge (CEDC) is saving kilowatts one school at a time, and the class that trims the most could end up being Janice Shelden’s grade threes, from Prince Charles Elementary in Surrey, B.C.

This year, Canadian Geographic Education and Shell Canada have teamed up with Global TV to follow one classroom as it works its way through the 25 energy-saving challenges. Already busy advocates for environmental conservation, Shelden and her students were selected from among 1,495 other classes in the country to serve as Global TV’s “Global Classroom.”

She and her kids are certainly worthy of the title — they raise salmon in the classroom and have become caretakers of Robson Park, a local green space. Learning crucial energy conservation lessons is part of this class’s daily routine.

“This knowledge allows students to make informed decisions about what they can do at school, at home and in their community to protect and conserve our planet, both now and for future generations,” says Shelden.

Global TV will film the class as it participates in the CEDC, gaining points toward its final score and a shot at the grand prize — $5,000 to be applied toward new technology for the winning school.

“Global Classroom” segments will be aired throughout the Challenge until April 25.
