Educating for Sustainability
UNIT: Wastewater Context for Matter and Its Interactions
LESSON: Reclaimed water
Part of a series of lessons in a unit called Wastewater Context for Matter and its interactions. Designed for middle school physical science, students will learn about reclaimed water and how it prevents the wastewater from ever entering the sound.
Suitable for Grades
Satisfies Academic Standards:
OSPI ESE 2: The Natural & Built Environment
OSPI ESE 3: Sustainability & Civic Responsibility
Sustainable System Focus:
- In chemical reactions mass is conserved
- Reclaimed water can add to our water supply and be used for a variety of non-drinking applications
Wastewater that would otherwise be released into the sound can be redirected to irrigation and other applications so that fresh water may be conserved
- Video: New York Times - Reclaimed water
- Video: A Singapore Success Story
- Powerpoint Slides
- King County Reclaimed Water Diagram
Time needed: 1 period or shorter
- Have students watch the : New York Times - Reclaimed water video and have a discussion
- Have students watch A Singapore Success Story and have a discussion
- Share with students the Powerpoint Slides so they can add the scientific principle and application.
- Share the rest of the slides and the King County Reclaimed Water Diagram. Have a discussion about what King County should do with its reclaimed water. Should the program be expanded like Singapore’s?
