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.

Acadia National Park

Acids and Bases

• Type: Lesson Plan
• Grade Levels: Upper Elementary: Third Grade through Fifth Grade

Students will do a simple experiment to become more familiar with what an acid is and what is a base

Olympic National Park

What Do Salmon Need To Survive?

• Type: Lesson Plan
• Grade Levels: Lower Elementary: Pre-Kindergarten through Second Grade

Students will be able to determine if salmon raised at school will survive in a local water source by testing conditions.

Kenai Fjords National Park

The Scientific Method

• Type: Lesson Plan
• Grade Levels: High School: Ninth Grade through Twelfth Grade

Students will conduct a basic soil science experiment and re-familiarize themselves with the scientific method.

National Park of American Samoa

Coral Reefs: Ecosystems Dissolving

• Type: Lesson Plan
• Grade Levels: Middle School: Sixth Grade through Eighth Grade

Corals face in our modern world, a great threat due to a projected change in water chemistry in the ocean due to global warming. Just as carbon dioxide (the main greenhouse gas causing global warming) is increasing in the air, it also increases in seawater in its dissolved form. That makes seawater more acidic which, in turn, may slow the rate at which corals build their calcium carbonate skeletons.
