Students will construct a model of the carbon cycle to explore the cycling of matter in decomposition. Students will design a process to compost food waste and recycle products used during lunchtime to reduce the amount of garbage the school produces.

In this lesson, students will research matter cycles in various ecosystems. They will develop a model that will show the movement of matter among plants, animals, decomposers, and the environment. Students will choose between a variety of ways to create their model.  (Preview Image: “Food web nemo”, CC-BY-SA 4.0, from Wikimedia Commons)
