Throughout its 15 years, Kids Teaching Kids has been enlisting green army recruits.

Their mission: to educate themselves, their classmates and their communities about issues like climate change, conservation, energy, water, and population growth.

Using science experiments, theatrical performances, songs and hands on workshops, the students from Neville, Carcoar, Blayney and Bedgerebong taught each other about environmental issues including sustainable farming, potatoes, native bees and the water cycle.

The students also had the opportunity to participate in many hands on workshops run by local groups including basket weaving, tree planting, soil identification and exploring the local water catchment.

Kids Teaching Kids creator Arron Wood, who was Environmentalist of the Year for his environmental education efforts, said that Australia should be proud of its kids' green army.

"Education is their weapon of choice. Green army recruits are all under the age of 17 and they've been fighting the good fight for the environment for the past 15 years. Kids Teaching Kids is about empowering the youth of this country to declare war on pollution, habitat destruction and global warming," Arron said.

"Our green-armed forces have been achieving some phenomenal results - whether it's the restoration of a wetland area or the establishment of a waste water campaign or things as simple as school recycling programs, kids have wonderful ideas and this program allows them to put their concepts into action."

The students at Neville are now preparing for their next conference at Henry Lawson High School in September.
