September 26, 2012 marks the third National Tree Day in Canada. National Tree Day is a celebration for all Canadians to appreciate the great benefits that trees provide us – clean air, reducing energy demand, wildlife habitat and connecting with nature. National Tree Day is the celebration of trees and forests in all neighbourhoods across Canada. As part of National Tree Day, the grade 3 and 4/5 classes from St. David Catholic School, in the Donovan, took their classrooms outdoors to visit the proposed site of their new school to observe trees in the area. Students were able to identify and describe the various trees that they saw incorporating language and science into their outdoor activities. The outdoor lessons focused on how the natural environment functions and how as human beings we can live in balance with nature as long as we remain committed to responsible behaviours and actions that protect our local ecosystems.
