Water quality is measured using many physical, chemical, and biological assessments. In this lesson, introduce your students to five water chemistry tests. Students will become familiar with pH, nitrates, phosphates, dissolved oxygen and turbidity and their relationship to the Cuyahoga River Watershed. They will begin to understand acceptable test value ranges, make connections between water quality and the biological community and become familiar with the causes of poor water quality.
