Resources for Teaching about Biogeochemical Cycles


Educators! Are you looking for a way to get your students thinking about the Earth as an interconnected system? If so, consider introducing them to biogeochemical cycles. Through these cycles of the Earth system, such as the carbon and nitrogen cycles, elements travel between the atmosphere, hydrosphere, biosphere, and geosphere. Learning about these cycles gives students an understanding of some of the connections between "spheres" of the Earth system!

The resources below are from Windows to the Universe and our partners. We hope you find them useful as you include Earth system science in your classroom!
