Lesson 3: Water Quality and Public Health
The purpose of this lesson is to explore how water quality affects human health. The importance of this issue has led to the separation of drinking water from wastewater in most developed countries. When potable water is not separated from other types of water, the risk of disease and infection from microorganisms and toxic chemicals increases. Students will learn about common contaminants found in untreated water and explore ways that the water can be made potable. Students will participate in an activity to create a water filter prototype and test its effectiveness.
