The composting extracurricular activity aims to expose students to the scientific principles underlying the composting process through the perspective of biogeochemical cycles and—more broadly—to notions of eco-citizenship and sustainable development.
Food compost made from fruit and vegetable waste and coffee grounds is collected from containers placed in locations around the school and added to our vermicompost bins. These bins contain worms that specialize in composting food. In order to collect the worm castings, students empty out the contents of the vermicompost bins and separate the worms from the soil. The worms are then returned to their bins to continue composting, and the soil is eventually used in the school garden and for growing seedlings.
