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.
