In this lesson, the students look at the components of cells and their functions. The lesson focuses on the difference between prokaryotic and eukaryotic cells. Each part of the cell performs a specific function that is vital for the cell's survival. Bacteria are single-celled organisms that are very important to engineers. Engineers can use bacteria to break down toxic materials in a process called bioremediation, and they can also kill or disable harmful bacteria through disinfection.

D-Lab is a design studio course in which students work on international development projects for under served communities. The class is focused on a participatory, iterative prototyping design process, with particular attention on the constraints faced when designing for developing communities. Students work in multidisciplinary teams on term-long projects in collaboration with community partners, field practitioners, and experts in relevant fields. Students will learn about their partner communities through the collaborative design process and be exposed to many hands-on fabrication and prototyping skills relevant to development at MIT and manufacturing in their partner community. The course will consist of hands-on labs, guest speakers, and a guided design process with review by experts and professionals in development and design.

D-Lab is a year-long series of courses and field trips. The fall class provides a basic background in international development and appropriate technology though guest speakers, case studies and hands-on exercises. Students will also have the opportunity to participate in an IAP fieldtrip to Haiti, India, Brazil, Honduras, Zambia, Samoa, or Lesotho and continue their work in a spring term design class. As part of the fall class, students will partner with community organizations in these countries and develop plans for the IAP site visit. In addition, students will learn about the culture, language, economics, politics and history of their host country.

In this activity, students investigate different methods (aeration and filtering) for removing pollutants from water. They will design and build their own water filters.

Core requirements for Environmental M.Eng. program. Designed to teach about environmental engineering through the use of case studies, computer software tools, and seminars from industrial experts. Case studies provide basis for group project as well as individual thesis. Past case studies have included the MMR Superfund site on Cape Cod; restoration of the Florida Everglades; dredging of Boston Harbor; local watershed trading programs; appropriate wastewater treatment technology for Brazil; point-of-use water treatment for Nepal, Brownfields Development in Providence, RI, and water resource planning for the island of Cyprus. Students must register for 1.782 for Fall term, IAP, and Spring term.

"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."

Between 70 and 75% of the Earth's surface is covered with water and there exists still more water in the atmosphere and underground in aquifers. In this lesson, students learn about water bodies on the planet Earth and their various uses and qualities. They will learn about several ways that engineers are working to maintain and conserve water sources. They will also think about their role in water conservation.

In this activity, students will use a tutorial on the U.S. Environmental Protection Agency's website to learn about how surface water is treated to make it safe to drink.

This sophomore-level course is a project-oriented introduction to the principles and practice of engineering design. Design projects and exercises are chosen that relate to the built and natural environments. Emphasis is placed on achieving function and sustainability through choice of materials and processes, compatibility with natural cycles, and the use of active or adaptive systems. The course also encourages development of hands-on skills, teamwork, and communication; exercises and projects engage students in the building, implementation, and testing of their designs.

In this sophomore design course, you will be challenged with three design tasks: a first concerning water resources/treatment, a second concerning structural design, and a third focusing on the conceptual (re)design of a large system, Boston's Back Bay. The first two tasks require the design, fabrication and testing of hardware. Several laboratory experiments will be carried out and lectures will be presented to introduce students to the conceptual and experimental basis for design in both domains.

This segment from a WPSU documentary Liquid Assets succinctly explains how water in New York journeys from its source to our faucets. Although water flows under our feet everyday, we are blissfully unaware of this service and take it for granted.

Students gain an understanding of the parts of a plant, plant types and how they produce their own food from sunlight through photosynthesis. They also learn about transpiration, the process by which plants release moisture to the atmosphere. With this understanding, students test the effects of photosynthesis and transpiration by growing a plant from seed. They learn how plants play an important part in maintaining a balanced environment in which the living organisms of the Earth survive. This lesson is part of a series of six lessons in which students use their evolving understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.

In this lesson, students will explore the causes of water pollution and its effects on the environment through the use of models and scientific investigation. In the accompanying activities, they will investigate filtration and aeration processes as they are used for removing pollutants from water. Lastly, they will learn about the role of engineers in water treatment systems.
