How Clear Is the Water?
- Type: Lesson Plan
- Grade Levels: High School: Ninth Grade through Twelfth Grade
In this lesson students will test their knowledge of ecosystems and the qualities necessary to sustain life by creating Secchi disks, testing turbidity (water clarity), and making predictions about the habitat that might exist. This fun, hands-on lesson allows students to be the scientist and make predictions based on their findings in their lab reports.
Cuyahoga Valley National Park
What's in the Water?
- Type: Lesson Plan
- Grade Levels: High School: Ninth Grade through Twelfth Grade
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.
