Summary: The field-based “Human Impact Survey” lesson plan from Alaska Sea Grant is one part of a larger curriculum unit that focuses on the relationship between humans and the ocean. In this lesson, students construct knowledge about aquatic pollution through firsthand exploration of the local environment.
Concepts to teach: Pollution, marine debris, biodegradable, decomposition
Goals: Students develop a common definition of the term ‘pollution’, and identify some sources of pollution. Students increase their awareness of pollution in their local environment (school, neighborhood) and feel empowered to devise and carry out solutions.
S8.3S1, S8.3S2, SS.08.GE.07
- Define what makes something a pollutant, and identify several common types and sources of pollution at a local field site.
- Describe how local pollutants make their way into aquatic and marine environments.
- Determine what actions or changes are needed to reduce pollution at the local field site.
Activity Links and Resources:
- Human Impact Survey—This lesson plan is from the Alaska Sea Grant’s K-8 Alaska Seas and Rivers Curriculum. Includes survey data sheets (ASG Human Impact Survey). This activity can be conducted on a beach or riverbank, or it may be adapted to apply to a park or schoolyard.
- Consider combining the survey with a SOLVE (or similar) beach or river cleanup effort.
- Map pollutants and their pathways. Use local maps from the Land and Water Use focus area to identify pollutant pathways, storm drains, and nearby streams and rivers.
- Use the human impact survey to design and carry out a stewardship project.
- Use pre- and post-activity concept maps to explore learner’s understanding of the term “pollution” and local types and sources of pollution.
- Worksheet included in the Human Impact Survey curriculum.
