- Type: Lesson Plan
- Grade Levels: High School: Ninth Grade through Twelfth Grade
For this activity students will create a brochure for farmers. The brochure will describe the needs each crop has (soil type, weather, etc.), the impact of the crop on the soil and the different ways the crop can be used. Students will focus on cotton, tobacco, peanuts, soybeans and sweet potatoes. The goal is for students to understand the impact cash crops may have on soil quality and how farmers can replenish their soil through crop rotation.

- 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.
