Curated OER
Nitrogen Cycle
Students identify the main concepts and ideas of the nitrogen cycle.
They review key concepts covered up to this point in ecology including food chains, food webs, energy pyramids, and bio-geochemical cycles.
Curated OER
The Nitrogen Cycle
Students study the nitrogen cycle and construct a diagram. In this Earth Science lesson students use role play to see the various paths.
