My first experience teaching climate change came after a unit covering the mechanisms and impacts of climate change. After this unit, I realized students may have a pessimistic outlook on the future. However, in the past humans have successfully reversed some major environmental problems. One example is banning the use of DDT (dichloro-diphenyl-trichloroethane) as an insecticide which caused birds egg shells to be too thin. Another example is a global agreement to stop the use of chlorofluorocarbons (CFC) which caused a hole in the ozone layer. Also the banning of lead in gasoline was another environmental success. The unit presented here is a engineering solutions oriented unit focused on climate mitigation. The mitigation strategies considered are carbon sequestration and alternative energies. This unit will cover the engineering design process with activities to practice this process while learning about carbon sequestration or wind energy. Information provided here includes background on climate change, information on the engineering design process, and different alternative energies or carbon sequestration.

This capstone course is a group design project involving integration of nuclear physics, particle transport, control, heat transfer, safety, instrumentation, materials, environmental impact, and economic optimization. It provides opportunities to synthesize knowledge acquired in nuclear and non-nuclear subjects and apply this knowledge to practical problems of current interest in nuclear applications design. Each year, the class takes on a different design project; this year, the project is a power plant design that ties together the creation of emission-free electricity with carbon sequestration and fossil fuel displacement. Students taking graduate version complete additional assignments.
This course is an elective subject in MIT’s undergraduate Energy Studies Minor. This Institute-wide program complements the deep expertise obtained in any major with a broad understanding of the interlinked realms of science, technology, and social sciences as they relate to energy and associated environmental challenges.

“Ocean Acidification, Imminent Mass Extinction?” is a unit for an Earth, Physical, or Environmental Science classroom. This unit is easily included in larger curricula focusing on climate change, the carbon cycle, human impact on Earth, or ocean chemistry. A backdrop for the unit is that ocean acidification may be jeopardizing global primary production because phytoplankton are being forced to adapt to a lower and lower pH. Loss of this piece of the food web has the potential to collapse massive, if not the most massive, ecosystems, hence mass extinction. Past mass extinction events are briefly discussed.

The unit begins by presenting the phenomenon of an ocean pH that is changing and then delves into the chemistry behind the change. The unit also considers the biological consequences of an ocean that is more acidic than it had been in millennia. Furthermore, implications to global carbon cycling are considered as the planet relies on microscopic ocean creatures to sequester carbon and transport it into long term storage. Lastly, the unit presents some recent research into the effects of the increased ocean acidity on an array of different organisms. Student activities are focused on hands on demonstrations that help students gain an understanding of pH; how pH is affected by carbon dioxide; and how shells are vulnerable to acidic conditons.

Students will examine the carbon cycle and examine how cattle grazing grasslands can improve and impact ecological succession. The Sandhills of Nebraska represent the largest sand dune formations in the Western Hemisphere and one of the largest grass-stabilized dune formations in the world.  There are approximately 670 native plant species that cover the Sandhills and over 500,000 beef cows call this place home.  By Brent Nollette

This course teaches principles of flow, transport, and reaction processes in the natural subsurface.

12.000 Solving Complex Problems is designed to provide students the opportunity to work as part of a team to propose solutions to a complex problem that requires an interdisciplinary approach. For the students of the class of 2013, 12.000 will revolve around the issues associated with what we can and must do about the steadily increasing amounts CO in Earth’s atmosphere.
12.000 is a core course for the MIT Terrascope freshman learning community. Each year's class explores a different problem in detail through the study of complementary case histories and the development of creative solution strategies. It includes training in Web site development, effective written and oral communication, and team building. Initially developed with major financial support from the d'Arbeloff Fund for Excellence in Education, 12.000 is designed to enhance the freshman experience by helping students develop contexts for other subjects in the sciences and humanities, and by helping them to establish learning communities that include upperclassmen, faculty, MIT alumni, and professionals in science and engineering fields.
