The Air We Breathe

Abstract:: Students learn what causes air pollution and how to investigate the different pollutants that exist, such as toxic gases and particulate matter. They investigate the technologies developed by engineers to reduce air pollution.

Environmental Engineering

Abstract:: In this unit, students explore the various roles of environmental engineers, including: environmental cleanup, water quality, groundwater resources, surface water and groundwater flow, water contamination, waste disposal and air pollution. Specifically, students learn about the factors that affect water quality and the conditions that allow for different animals and plants to survive in their environment. Next, students learn about groundwater and how environmental engineers study groundwater to predict the distribution of surface pollution. Students also learn how water flows through the ground, what an aquifer is and what soil properties are used to predict groundwater flow. Additionally, students discover that the water they drink everyday comes from many different sources, including surface water and groundwater. They investigate possible scenarios of drinking water contamination and how contaminants can negatively affect the organisms that come in contact with them. Students learn about the three most common methods of waste disposal and how environmental engineers continue to develop technologies to dispose of trash. Lastly, students learn what causes air pollution and how to investigate the different pollutants that exist, such as toxic gases and particulate matter. Also, they investigate the technologies developed by engineers to reduce air pollution.

Abstract:: 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.
