Educating for Sustainability
UNIT: Wastewater Context for Matter and Its Interactions
LESSON: Is there a problem in Puget Sound?
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 understand the problems Puget Sound organisms face because of our wastewater system.
Suitable for Grades
Satisfies Academic Standards:
MS-PS1-3 - Synthetic Materials
Sustainable System Focus:
Buildings and Urban Planning
A lot of the the economy and recreation in the Puget sound is based on the Puget sound and the organisms that live there. In this lesson students realize that what they are doing everyday is having a negative impact on the Sound. This raises the need to understand the wastewater treatment system and the properties of the matter they put down the drain
Puget sound vital signs - Marine Water Quality
Students do a jigsaw reading of issues faced by Puget Sound organisms as the result of human wastewater.
- Powerpoint slides
- Salmon on Drugs Article
- Shellfish Cannot say “no” to drugs
- How your clothes are poisoning our oceans and food supply
- Polluting the water with toothpaste and household chemicals
- Student Sheet - Process grid
Time needed: .5 to .75 of a class period
- Provide each person in a group of 4 with a different articles.
- Provide students with an amount of time to read and gather information about their article (7-10 minutes)
- Group students by article - two groups per article- for them to confirm and solidify their information
- Have students report back to their group and share what their information with the rest of the group. As students report, all other students in group record in their own process grid.
- Facilitate a class discussion where representatives from each group share their responses and you fill out the grid with them on screen with the PowerPoint provided.
- In the discussion: let students know that drugs get into the water by people dumping them into toilets and simply peeing after they are taken. Reassure students because some will feel guilty because they have to take medication. Tell them that human health is important, we just have to find a way to get the substances out cheaply and easily. Maybe they will be the one that figure it out
