StreamWatch: This lesson is intended as a long term project to determine the overall health of a stream or wetland. Students identify seasonal changes that occur within the ecosystem, ideally with a minimum of bimonthly or monthly monitoring.; Format: lesson plan (grade 9–12 Science); By B. Carl Rush.

Round and Round It Goes; Water, Where It Stops Nobody Knows: The hydrologic cycle is the process, powered by the sun, which identifies the constant, endless movement of water from the atmosphere to the earth to the ground water, to the rivers to the oceans and back into the atmosphere. This experimental lab lesson will show the process of the hydrologic cycle as it relates to the earth's atmosphere by showing three different scenarios,the first scenario (the control), container A, shows the hydrologic cycle with no contaminates. The second scenario, container B, shows the hydrologic cycle with the earth's soil contaminated. The third scenario, container C, demonstrates the hydologic cycle with the air polluted. These three situations will give the student an idea of how the atmosphere and the growth of plant life are affected by different contaminants in the earth.This lesson will, in fact, investigate the hydrologic cycle experimentally.; Format: lesson plan (grade 9–12 Science); By Mark Clinkscales and Carrie Palmer.

A case study of "A Civil Action": In Bringing current science into the classroom, page 3; This is a short, culminating activity that can be used to assess your students' understanding of the steps needed to determine if a water source is contaminated and how it got that way, and to suggest possible methods of cleanup or remediation. Students review a portion of the film "A Civil Action" and identify the problem and the people involved. Students then take the role of environmental scientist and apply their knowledge of water and hazardous waste contamination to create a plan to help lawyer, Jan Schlichtmann, try the case.; Format: (grade 9–12 Science); By Michele Kloda.

What's wrong with the oceans? Can photography help?: In this lesson from Xpeditions, students will research environmental problems facing the world's oceans and will think about how the art of photography can help solve these problems.
