I decided to look for information related to the geobiochemical cycles. This is a difficult concept to get high school students to pay attention to. They all know the water cycle and are not much interested in the other cycles. I am always looking for new ways to present information for this unit.

Open educational resources of different types for geobiochemical cycles are below.

I have linked all of the material and it is found searching the creative commons search but I am never sure if I have cited the material correctly.
