Original Prompt

This goal is crucial because it serves as a culminating activity for Lesson Set 1, where students synthesize all previous learning about peat, permafrost, decomposition, cellular respiration, photosynthesis, and solar energy to explain the anchoring phenomenon of zombie fires. It demonstrates their ability to integrate complex scientific concepts into a coherent systems model of matter and energy flow.

This learning resource explores the concept of 'zombie fires,' which are underground smoldering fires that can reignite and cause surface wildfires, particularly in Arctic regions like Siberia and Alaska. The text discusses the unique characteristics of peat and permafrost that contribute to these phenomena, emphasizing their roles in the carbon cycle, energy flow, and ecological relationships. Students are encouraged to activate their knowledge through questions about the carbon cycle and to create a systems model illustrating the pathways of energy and matter related to zombie fires. The resource also prompts critical reflection on climate change impacts within Arctic ecosystems, fostering an understanding of broader environmental implications.
