The EcoClub at Earl Haig Secondary School takes a very different approach to learning about climate change through its focus on garbage. While many are involved in the school’s waste audit, from the principal to teachers and caretakers, it is the students who lead the process by collecting and sorting the garbage, and then measuring and interpreting the audit results. This sticky, smelly form of learning brings with it groans, laughter, and disgust at the amount and type of waste created, but it also builds comradery and integrates learning in math, literacy and critical thinking to inform the goals for the EcoClub for the year. This immersive investigation could result in helping the school community to better separate out compostable and recyclable items from its garbage heading to landfill; reducing the amount of single-use plastics in the school cafeteria; or increasing understanding of the problems of micro-plastics in the lake. The results of this learning are quantifiable; research has demonstrated that certified EcoSchools generate half as much waste per student per year as do non-certified schools.
