The Science and Ethics of Compost: Using Inquiry to Foster Environmentally Responsible Behavior

Organic decomposition is the natural process by which organic matter breaks down into simpler materials through the actions of decomposers such as fungi, microorganisms, and other decomposers that ultimately recycle nutrients back into an ecosystem. Despite having experiences with mold and decay, many students would benefit from developing a deep understanding of the biological science ideas that underpin decomposition. Moreover, with explicit attention, the ideas of organic decomposition can be used to engage students in thoughtful consideration of personal and community environmental habits, particularly with littering, disposing of waste, and avoiding unnecessary plastics. However, these connections are rarely intuitive and require concrete learning experiences with deliberate scaffolding to make connections between scientific ideas and environmental mindfulness. This composting inquiry activity with scaffolding promotes students’ deep understanding of matter cycling and environmentally responsible mindfulness and action. While knowledge is not likely to result in environmental behaviors, it is a crucial predecessor to responsible action.
