Lesson Presentation 
This lesson can be taught at any time in the Water Quality module; it allows the students to get a feel for how temperature effects the environment. The lesson uses real world examples to demonstrate the different factors that affect the temperature of a body of water.  As the students go through the presentation, they will be exposed to different bodies of water as well as the subject of water pollution.  For class discussion, the teacher may want to emphasize the interactive animation of how the fish reacts to different temperatures in its environment.  The teacher may also want to use other interactive examples that are not able to be used via the internet.

Activity
The activity is designed to help students appreciate how temperature fluctuation in an organism's environment can affect the organism.  In this experiment, the students will observe fish in water of various temperatures.  The teacher may want to demonstrate to the class how to observe and quantify the movements of the fish.  The students should notice differences in the fish's behavior, if the experiment goes smoothly.  They should also gain an appreciation for how temperature changes effect the physiological functioning of the fish.

Note:  There may not be any results that students can observe in the experiment.  But that is okay!  It is part of the scientific method.  Not all experiments produce results.  If nothing happens, have them explain why and have them explain what they would do to change the experiment so that there would be observable changes.
