Lesson Plans: Water Quality for Freshwater Organisms The purpose of this activity is to demonstrate to students the effect increased water temperature has on the amount of dissolved oxygen found in water and in turn upon the gill beat rate of fish. What's the red in the water? Tutorial with Text & Images. "Collecting the bacteria and viewing them through a microscope is one way to tell important differences in the water chemistry from one site to the next."

They will examine how industrial and residential runoff affects the bay, identify the importance of underwater bay grasses, and describe how decreased oyster production in the bay both is caused by and contributes to poor water quality. Water Lesson Plans A series of lessons that summarize the hydrologic cycle, define water pollution, conduct various LaMotte tests for pollutants, interpret test results compared to a set of water quality standards, identify possible sources of different kinds of pollutants, and explain possible engineering solutions to some kinds of water pollution.
