Activity 2: Water Filtration – Natural Surfaces versus Impervious Surfaces


In this lesson, students learn the value of clean freshwater and the natural processes that ensure an adequate supply of usable freshwater. In activity 2, students conduct a hands-on activity that focuses on the role of natural areas as filters that produce clean water. Such natural filters are contrasted with impervious (paved) areas to compare the impact of development on the ability of nature to provide clean freshwater.
