## [Engineering Water Filtration Devices In this unit, students focus on interactions between the hydrosphere and the geosphere as they explore the phenomena of groundwater in human development. For this lesson, they engineer a water filtration device to treat samples of simulated polluted stormwater runoff. This page highlights key components of this lesson.](https://www.knowatom.com/science-phenomena-videos/7th-grade-science/engineering-water-filtration-devices)
