Water Quality Assessment

Module Summary
Water quality assessment is vital to determining the health of an ecosystem. Humans and local wildlife rely on clean water for drinking, living and recreating. This module is intended to help students assess the quality of a local aquatic environment through a series of interactive activities. At the end of the module students will have knowledge of several tools that can be
used to assess water quality. Students begin by assessing the biotic and abiotic factors of the water body. They then complete a leaf pack experiment that spans 2-3 months where they look at leaf decomposition in an aquatic environment and assess local macroinvertebrates. Additionally, students work to create a map of their local watershed and relate that to potential
sources of water pollution in the area.
