"This class is one of the core requirements for the Environmental Masters of Engineering program, in conjunction with 1.133 Masters of Engineering Concepts of Engineering Practice. It is designed to teach about environmental engineering through the use of case studies, computer software tools, and seminars from industrial experts. Case studies provide the basis for group projects as well as individual theses. Recent 1.782 projects include the MMR Superfund site on Cape Cod, appropriate wastewater treatment technology for Brazil and Honduras, point-of-use water treatment and safe storage procedures for Nepal and Ghana, Brownfields Development in Providence, RI, and water resource planning for the island of Cyprus and refugee settlements in Thailand. This class spans the entire academic year; students must register for the Fall and Spring terms."

Students are introduced to the fundamentals of environmental engineering as well as the global air, land and water quality concerns facing today's environmental engineers. After a lesson and activity to introduce environmental engineering, students learn more about water chemistry aspects of environmental engineering. Specifically, they focus on groundwater contamination and remediation, including sources of contamination, adverse health effects of contaminated drinking water, and current and new remediation techniques. Several lab activities provide hands-on experiences with topics relevant to environmental engineering concerns and technologies, including removal efficiencies of activated carbon in water filtration, measuring pH, chromatography as a physical separation method, density and miscibility.

Examines health issues, scientific understanding of causes, and possible future approaches to control of the major environmental health problems in industrialized and developing countries. Topics include how the body reacts to environmental pollutants; physical, chemical, and biological agents of environmental contamination; vectors for dissemination (air, water, soil); solid and hazardous waste; susceptible populations; biomarkers and risk analysis; the scientific basis for policy decisions; and emerging global environmental health problems.

Students develop critical thinking skills by interviewing a person who has perspective on environmental history. Students explore the concept of a timeline, including historical milestones, and develop a sense of the context of events.

In this activity, students create a "web" to identify and demonstrate the interactions among the living and non-living parts of an environment. This information allows students to better understand what an environment is and to also consider how engineers use teamwork to solve problems.

A general introduction to the diverse roles of microorganisms in natural and artificial environments. Topics include: cellular architecture, energetics, and growth; evolution and gene flow; population and community dynamics; air, water, and soil microbiology; biogeochemical cycling; and microorganisms in biodeterioration, bioremediation, and pest control.

Examines the collision of politics, economics, values, and science in making and carrying out environmental policy at national, state, and local levels. Case studies of environmental policymaking explore the roles of governmental institutions, business, interest groups, the public, and the media in areas of air and water pollution, hazardous waste disposal, public lands management, and wildlife protection. "Environmental Politics and Policy" explores the workings of environmental policymaking in the United States. What are the big issues facing environmental policy? How did we end up with the policies we have today? Why does it take a crisis to move environmental policy forward? Why do political factors - economic interests, social and political values, bureaucratic styles, ideologies, elections, etc. - always seem to overwhelm sound scientific and engineering judgment in determining policy outcomes? Case studies ranging from cleaning up toxic waste pollution to endangered species protection probe the clashes between science and politics at local, state, and federal levels.

In this case study, two students have been asked to conduct a "systems analysis" study to determine whether ethanol derived from corn or biodiesel prepared from soybeans is the more energy efficient alternative fuel. The students must investigate the two systems very broadly to determine all energy inputs and outputs. When the corn-to-ethanol system turns out to be less energy efficient, the students are asked to consider the political and economic consequences of this and the role that science plays in making policy decisions. The case is designed for general chemistry courses and non-science majors' chemistry courses.

The release of toxins into the environment and the federal government's tracking of that using the Toxic Release Inventory (TRI) compiled by the U.S. Environmental Protection Agency (EPA) are the focus of this case study, which uses GIS to explore the potential impacts of the release of such substances. The case was developed for an introductory environmental studies course. It would also be appropriate for use in an introductory GIS course or cartography course where some analysis is required, an introductory chemistry course for non-majors (with some more prep work on partitioning coefficients and fate and transport), or a basic soils course where remediation techniques are emphasized. The case study requires ESRI's ArcView 3.3 software in a computer lab setting, although it could easily be adapted for use with ArcGIS 9.x.

Students conduct experiments to determine the flow rate of faucets by timing how long it takes to fill gallon jugs. They do this for three different faucet flow levels (quarter blast, half blast, full blast), averaging three trials for each level. They convert their results from gallons per second (gps) to cubic feet per second (cfs).

Developed for an introductory environmental studies course, this case study explores the ecological, economic, and legislative issues associated with land development and wetland loss. Students role-play the points of view of four different stakeholders and then write a report that provides specific recommendations for the mayor of a city considering an expansion of the metropolitan airport that will result in the loss of wetlands. Biodiversity is a topic that students typically associate with tropical regions of the world. A strength of this case is that it brings this topic home by connecting biodiversity with tradeoffs involved in local economic development, with the functional value of wetlands, and with the controversy surrounding wetland "mitigation" as a means of achieving the national "no net wetland loss" policy goal.

In this case study, students speculate on what may have caused a major fish kill in an estuary in North Carolina. In the process, they explore how land runoff and excess nutrients affect aquatic communities, and learn about the complex life cycle of the dinoflagellate Pfiesteria. The case is appropriate for an introductory environmental science course, a general biology course that covers ecology, or a general zoology course.

In this case study, students examine data from a number of published studies of the effects of Pacific salmon on freshwater and riparian ecosystems. The case focuses on the interesting phenomenon of spawning salmon acting as nutrient conveyor belts, transporting nutrients from the ocean upstream into freshwater spawning areas and, in some cases, even onto land, reversing the more-typical downstream movement of nutrients. As students work at analyzing and interpreting graphical data, they will also increase their understanding of the principles of biogeochemical cycling and gain an appreciation for the interconnectedness of different types of ecosystems. The topic is appropriate for any course covering ecosystem ecology including, for example, general ecology, freshwater or marine ecology, and environmental science.

This "clicker case" addresses the eutrophication of aquatic systems caused by human activities. "Susan" is a biology student working at a seafood restaurant on the Gulf of Mexico. She discovers that the restaurant doesn't serve locally caught shrimp because shrimp populations are in decline. While searching for an explanation, Susan learns about the nitrogen cycle as well as interactions between species, the abiotic and biotic environment, and multiple ecosystems (terrestrial and aquatic). Developed for a large introductory biology course, the case combines the use of student personal response systems ("clickers") with case teaching methods and formats. It is presented in class using a series of PowerPoint slides (~3.8MB) punctuated by questions that students respond to using their clickers. The case could be adapted for use without these technologies.

In the Flow Rate Experiment, students perform hands-on experiments with a common faucet, as well as work with the Engineering Our Water Living Lab to gain a better understanding of flow rate and how it pertains to engineering and applied science. Students calculate the flow rate of a faucet for three different levels (quarter blast, half blast, and full blast). Building on these calculations, students hypothesize about the flow rate in a nearby river, and then use the Engineering Our Water Living Lab to check their hypothesis. For this lesson to be effective, your students need to have a visual feel for the flow in a nearby river.

This discussion case, in which a university research laboratory is vandalized by environmental activists opposed to genetic engineering, focuses on the science and ethics of genetically modified crops. Students consider both the risks and benefits of biotechnology and explore the positions of various stakeholders, including environmentalists, conservationists, agricultural businesses, research scientists, and farmers. Originally written for a vegetable crops course, the case would be appropriate for a wide variety of courses in which biotechnology is discussed.

These materials support BBC's Frozen Planet, a study of the Arctic and Antarctic environments. Resources include video clips, interactive maps and a free course that examine these regions and how ice has shaped the landscapes, determines the structure of the ecosystem and the animals that prosper, and even drives our global climate.

This lesson plan explores the fundamentals of atoms and their structure. The building blocks of matter (protons, electrons, neutrons) are covered in detail. Students think about how atoms and molecules can influence new technologies developed by engineers.
