The fourth graders visited the Wilmette Water Plant for a tour of this award-winning facility that provides drinking water to the residents of Wilmette, Glenview, the Village of Golf and parts of Prospect Heights. The fourth graders learned how water from Lake Michigan is treated so that it becomes safe for drinking. During the tour, they learned about the treatment chemicals, flocculation, sedimentation, and filtration.
Educators from SCARCE visited the fourth grade classrooms to teach the students about water pollution using the Enviroscope Watershed Model. The Enviroscope Watershed Model helps to explain point and non-point source pollution so that the students would learn about the origins of pollution in a community.
The students learned that water pollution is a big problem because drinking water is scarce – comprising only one percent of the world’s water. They learned about pollutants such as microbeads in toothpaste and face wash, medicines flushed down the toilet, garbage, and phosphates in fertilizer. SCARCE also taught the students about efforts and solutions to reduce water pollution such as permeable pavers to reduce sewer runoff, the use of native plants, greenrooms, rain barrels, composting and technological improvements to reduce water usage in processes such as the making of Levis jeans.
