High School Lesson Plans - Healthy Water

Got Water? PDF
Natural disasters affect human population on multiple levels. They can cause immediate death, injury, destruction of property and infrastructure, and disruption of services and mechanisms that protect persons from illness. This lesson plan specifically addresses the implications of a natural disaster and its effects on water quality and a community's health. Students will learn methods used during an emergency response to test and treat water that has been contaminated by pathogenic microorganisms. Water treatment options introduced can vary depending on the location and type of emergency involved, but have the same goal to reduce human illness and death. After completing this lesson, students will have an improved understanding of which organizations are involved in emergency response and why safe drinking water is a substantial heath concern after a natural disaster.
