Decomposition is a fascinating and complex process. This activity gives learners an opportunity to build an understanding of decomposition that is grounded in real-world examples and lays the foundation for concepts related to matter and energy transfer in ecosystems. First, learners study the process of decomposition through observation and discussion as they create a sequence of decomposing wood and leaves. Then, learners consider the difference between physical decomposition and chemical decomposition and discuss forces that contribute to decomposition. Learners search for and discuss evidence of decomposers, make model diagrams to develop their ideas about the process of decomposition, and discuss the role of decomposition in the cycling of matter. Finally, learners are invited to recognize the evidence and impact of decomposition in the ecosystems they will explore in the future.
We want to acknowledge Justice Outside for reviewing this session and supporting us to develop more equitable, inclusive, and culturally relevant instructional materials.
