EOU Exam on Thursday, May 1st

Lesson #2:

Water Pollution

&

Biomagnification

Learning Target

Students will be able to discover how pesticides and other toxins increase in accummalation as you increase trophic level.

Success Criteria

Engage: Students watch a video about water pollution and participate in "Turn & Talk" discussions where they share observations, thoughts, and questions about the video

Explore: Students examine the definitions of key vocabulary terms like "trophic level" and "biomagnification," learning how toxins accumulate in organisms as they move up the food chain.

Explain: Students explain, using the conjunctions "Because...But...So...", how human activities like pesticide use.

Elaborate: Students read an article about the impact of toxins on killer whales, applying their understanding of biomagnification to analyze a real-world case study.

Evaluate: Students consider the effectiveness of different solutions to reduce water pollution, such as stricter regulations on industrial discharge or promoting the use of eco-friendly pesticides.

Standards

HS-LS2-7.

Design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity

Biomagnification: An increase in concentration of a substance, such as a pesticide, toxin or heavy metal, in the tissues of organisms at you move up trophic levels.

Surface Run-Off: Runoff occurs when there is more water than land can absorb. The extra water flows across the surface of the land and into nearby creeks, streams and rivers. As it flows across the land it picks up pesticides, toxins, chemicals and heavy metals, depositing them into our waterways.
