Aquaponics: Exploring Nitrogen Cycling in a Closed System
Sean Mullen
2002- 2003 Fellow


Although nutrient cycling is a fundamental concept in ecology and environmental science, many students have trouble visualizing how individual nutrients such as nitrogen cycle through complex natural ecosystems. This unit addresses this issue by outlining an inquiry-based approach to investigating nutrient cycling in a simplified desktop ecosystem involving aquaria and hydroponically grown plants.

It is designed for use in high school Ecology, Environmental Science, or Biology classes and can be easily modified for use with younger students.

You can download this unit as a PDF file or HTML (web-based) document.
