Stream Science: Investigating Water Quality
Macroinvertebrate Survey & Stream Habitat Assessment

Students participating in this Meaningful Watershed Educational Experience (MWEE) conduct water quality monitoring of a local stream near their school and produce educational brochures about protecting local water quality. We will work with you to identify a location for a walking field trip and will bring all of the equipment for water chemistry testing and macroinvertebrate identification.
Best for Grades 4, 5
