Lesson Plan: Making Connections with Water Quality

In this unit, students will study the health of a water system by determining the balance between physical, chemical and biological variables.  Physical variables include temperature, turbidity, and water movement. Chemical variables include dissolved oxygen and other gases, pH, nitrates, and salinity.  The health of water systems is dependent on the balance of its many natural systems. Students will focus on contaminants that harm our water quality and will research means of water filtration.  This unit is designed to encourage students to apply prior knowledge of technology and water to determine if local water is safe for consumption.
