Experiment demonstrates the methodology used for measuring dissolved oxygen and determining the primary productivity of a natural body of water.

Dissolved oxygen levels are used to monitor the health and productivity of aquatic ecosystems. In this kit, students familiarize themselves with the Winkler method by examining the relationship between temperature and dissolved oxygen concentrations. Using local water samples to examine primary productivity at different water depths, students can then observe the beginning stages of eutrophication.
