Over the course of three sessions, students act as agricultural engineers and learn about the sustainable pest control technique known as soil biosolarization in which organic waste is used to help eliminate pests during soil solarization instead of using toxic compounds like pesticides and fumigants. Student teams prepare seed starter pots using a source of microorganisms (soil or compost) and “organic waste” (such as oatmeal, a source of carbon for the microorganisms). They plant seeds (representing weed seeds) in the pots, add water and cover them with plastic wrap. At experiment end, students count the weed seedlings and assess the efficacy of the soil biosolarization technique in inactivating the weed seeds. An experiment-guiding handout and pre/post quizzes are provided.

In this course participants will learn how to turn solar cells into full modules; and how to apply full modules to full photovoltaic systems.
The course will widely cover the design of photovoltaic systems, such as utility scale solar farms or residential scale systems (both on and off the grid). You will learn about the function and operation of various components including inverters, batteries, DC-DC converters and their interaction with both the modules and the grid.
After learning about the components, learners will be able to correctly apply them during main design steps taken when planning a real PV installation with excellent performance and reliability.
Through modelling, you will gain a deeper understanding of PV systems performance for different solar energy applications, and proficiency in estimating the energy yield of a client’s potential system.
This course is part of the Solar Energy Engineering MicroMasters Program designed to cover all physics and engineering aspects of photovoltaics: photovoltaic energy conversion, technologies and systems.

In this activity, students learn how engineers use solar energy to heat buildings by investigating the thermal storage properties of some common materials: sand, salt, water and shredded paper. Students then evaluate the usefulness of each material as a thermal storage material to be used as the thermal mass in a passive solar building.

This lesson introduces students to the space environment. It covers the major differences between the environment on Earth and that of outer space and the engineering challenges that arise because of these discrepancies. In order to prepare students for the upcoming lessons on the human body, this lesson challenges them to think about how their bodies would change and adapt in the unique environment of space.

This landscape and environmental planning workshop investigates and propose a framework for the enhancement, development and preservation of the natural and cultural landscape of the Cardener River Corridor in Catalunya Spain. The workshop is carried out in conjunction with the Polytechnic University of Catalunya, and the Barcelona Provincial Council (DiputaciĚ_ de Barcelona).

In this activity, students act as environmental engineers involved with the clean up of a toxic spill. Using bioremediation as the process, students select which bacteria they will use to eat up the pollutant spilled. Students learn how engineers use bioremediation to make organism degrade harmful chemicals. Engineers must make sure bacteria have everything they need to live and degrade contaminants for bioremediation to happen. Students learn about the needs of living things by setting up an experiment with yeast. The scientific method is reinforced as students must design the experiment themselves making sure they include a control and complete parts of a formal lab report.

Quantitative techniques for life cycle analysis of the impacts of materials extraction, processing use, and recycling; and economic analysis of materials processing, products, and markets. Student teams undertake a major case study of automobile manufacturing using the latest methods of analysis and computer-based models of materials process.

The goal of this activity is for students to develop visual literacy. They learn how images are manipulated for a powerful effect and how a photograph can make the invisible (pollutants that form acid rain) visible (through the damage they cause). The specific objective is to write captions for photographs.

Subject considers how the visual and material world of "nature" has been reshaped by industrial practices, beliefs, structures, and activities. Readings in historical geography, aesthetics, American history, environmental and ecological history, architecture, city planning, and landscape studies. Several field trips planned to visit local industrial landscapes. Assignments involve weekly short, written responses to the readings, and discussion-leading. Final project is a photo-essay on the student's choice of industrial site (photographic experience not necessary).
A survey of America's transition from a rural, agrarian, and artisan society …
A survey of America's transition from a rural, agrarian, and artisan society to one of the world's leading industrial powers. Treats the emergence of industrial capitalism: the rise of the factory system; new forms of power, transport, and communication; the advent of the large industrial corporation; the social relations of production; and the hallmarks of science-based industry. Views technology as part of the larger culture and reveals innovation as a process consisting of a range of possibilities that are chosen or rejected according to the social criteria of the time.

This course is an introduction to epistemology: the theory of knowledge. We will focus on skepticism—that is, the thesis that we know nothing at all—and we will survey a range of skeptical arguments and responses to skepticism.

Students show their creativity and think like engineers as they design products or services that can be used to improve environmental problems in the community. While being aware of the steps of the engineering design process, students are challenged to consider all aspects of their products/services, including their costs, and impacts on the environment and people in their communities. They present their "green" solutions, in the form of advertisements, to the class for critical review of their feasibility.

In this activity, students will review and evaluate the ways land is covered and used in their local community. They will also consider the environmental effects of the different types of land use. Students will act as community planning engineers to determine where to place a new structure that will have the least effect on the environment.
This course is the first subject in the Environmental Policy and Planning …
This course is the first subject in the Environmental Policy and Planning sequence. It reviews philosophical debates including growth vs. deep ecology, command-and-control" vs. market-oriented approaches to regulation, and the importance of expertise vs. indigenous knowledge. Its emphasis is placed on environmental planning techniques and strategies. Related topics include the management of sustainability, the politics of ecosystem management, environmental governance and the changing role of civil society, ecological economics, integrated assessment (combining environmental impact assessment (EIA) and risk assessment), joint fact finding in science-intensive policy disputes, environmental justice in poor communities of color, and environmental dispute resolution."

Student teams investigate the migration of small-particle plastic pollution by exposing invertebrates found in water samples from a local lake or river to fluorescent bead fragments in a controlled environment of their own designs. Students begin by reviewing the composition of food webs and considering the ethics of studies on live organisms. In their model microcosms, they set up a food web so as to trace the microbead migration from one invertebrate species to another. Students use blacklights and microscopes to observe and quantify their experimental results. They develop diagrams that explain their investigations—modeling the ecological impacts of microplastics.
