The Nitrogen Cycle - COSEE Coastal Trends

Lesson Plan 

Students put together “puzzle piece” print-outs of the compounds comprising the nitrogen cycle and string the pieces together to reconstruct the pathways of the cycle.

Concept: Geochemical cycles
The ocean is an integral part of the geochemical cycles. It is connected to land-based waterways, which transport materials to the ocean.
