Student groups use a "real" 3D coordinate system to plot points in space. Made from balsa wood or wooden dowels, the system has three axes at right angles and a plane (the XY plane) that can slide up and down the Z axis. Students are given several coordinates and asked to find these points in space. Then they find the coordinates of the eight corners of a box/cube with given dimensions.
Examines the history of the United States as a "nation of immigrants" within a broader global context. Considers migration from the mid-19th century to the present through case studies of such places as New York's Lower East Side, South Texas, Florida, and San Francisco's Chinatown. Examines the role of memory, media, and popular culture in shaping ideas about migration. Includes optional field trip to New York City.
This task can be implemented in a variety of ways. For a class with previous exposure to properties of perpendicular bisectors, part (a) could be a quick exercise in geometric constructions, and an application of the result. Alternatively, this could be part of an introduction to perpendicular bisectors, culminating in a full proof that the three perpendicular bisectors are concurrent at the circumcenter of the triangle, an essentially complete proof of which is found in the solution below.
The scientific community must be effective in communicating the results of its work to the public in a way that can be understood and used. The need for this is acute, for the complexity and difficulty of environmental and resource problems require full use of all the knowledge scientists can muster. The wisdom of the actions of both the government and private sectors depends in large part on their understanding of resource characteristics.
The U.S. Geological Survey is uniquely qualified to provide much of the required knowledge about natural resources through its many reports and maps and can be proud of the products of its work. Too often, however, reports are couched in words and phrases that are understandable only to other scientists, engineers, or technicians. But, who, really, are the ones to whom the Survey wishes to convey its findings? Other scientists and engineers, yes. But beyond them, by far a larger audience: teachers, students, businessmen, planners, and Federal, State, county, and municipal officials–in short, the public.
More than 50 years ago former Director George Otis Smith recognized the same problem. His plea for “Plain Geology” was a classic, just as applicable now as it was in 1921. It is herewith reprinted to make it generally available.

This is a simple exercise in creating equations from a situation with many variables. By giving three different scenarios, the problem requires students to keep going back to the definitions of the variables, thus emphasizing the importance of defining variables when you write an equation. In order to reinforce this aspect of the problem, the variables have not been given names that remind the student of what they stand for. The emphasis here is on setting up equations, not solving them.
This three-week module, centered on a focal case, represents the second part of the DepartmentŰŞs introduction to the challenges of reflection and action in professional planning practice. As such, it builds on the concepts and tools in 11.201 and 11.202 in the Fall semester. Working in teams, students will deliver a 20-minute oral briefing, with an additional 10 minutes for questions and comments, in the last week of the class (as detailed on the assignment and posted course schedule). The teams will brief invited guests (ŰĎbriefeesŰ) taking the roles of decisionmakers. DUSP faculty and fellow students may also be in attendance.
Subject focuses on methods of digital visualization and communication and their application to planning issues. Lectures introduce methods for describing or representing a place and its residents, for simulating actions and changes, for presenting visions of the future, and for engaging multiple actors in the process of envisioning change and guiding action. Laboratory time allows students to apply these methods by designing a web-based portfolio that is critiqued throughout the semester, and evolves as they advance through the program. This course focuses on methods of digital visualization and communication and their application to planning issues. Lectures will introduce a variety of methods for describing or representing a place and its residents, for simulating changes, for presenting visions of the future, and for engaging multiple actors in the process of guiding action. Through a series of laboratory exercises, students will apply these methods in the construction of a web-based portfolio. The portfolio is not only the final project for the course, but will serve as a container for other course work throughout the MCP program. This course aims to introduce students to (1) such persistent and recurring themes as place, race, power and the environment that face planners, (2) the role of digital technologies in representing, analyzing, and mobilizing communities, (3) MIT faculty and their work, (4) MIT's computing environment and resources including Athena, Element K, the ESRI virtual campus, Computer Resources Laboratory (CRL), Campus Wide Information Systems Support (CWIS), the GIS Laboratory at Rotch Library and (5) software tools like Adobe Photoshop and Illustrator, ESRI ArcView, Microsoft Access, and Macromediaĺ¨ Dreamweaver that will assist them in creating digital images, working with relational databases, and launching a web-based portfolio.

Planning Economics will apply microeconomic theory to issues that markets don't always handle well and so are not usually covered in a standard microeconomics course. Issues for this year include global warming, how you value a national park, the economics and politics of New York City development, how cities form and why people are willing to pay more to live in, say, the Boston Metro area, than they would pay to live in rural North Dakota, and how to evaluate costs and benefits that occur at different points in time.
Explores policy and planning for sustainable development. Critically examines concept of sustainability as a process of social, organizational, and political development drawing on cases from the US and Europe. Explores pathways to sustainability through debates on ecological modernization; sustainable technology development, international and intergenerational fairness, and democratic governance. Third subject in the Environmental Policy and Planning sequence.
During the last fifteen years, nations across the globe embarked on a historic transformation away from centrally planned economies to market-oriented ones. However, in the common pursuit for economic growth, these transition economies implemented widely different reform strategies with mixed results. With over a decade of empirical evidence now available, this new course examines this phenomenon that has pushed the discourse in a number of disciplines, requiring us to reconsider fundamental issues such as: - the proper relationship between business, government, and the public interest; - the possible synergies and tensions between economic growth and equity; and - how economic transition has reshaped cities. The premise of the course is that the primary issue in transition involves institution-building and re-building in different contexts.
What do plants need? Students examine the effects of light and air on green plants, learning the processes of photosynthesis and transpiration. Student teams plant seeds, placing some in sunlight and others in darkness. They make predictions about the outcomes and record ongoing observations of the condition of the stems, leaves and roots. Then, several healthy plants are placed in glass jars with lids overnight. Condensation forms, illustrating the process of transpiration, or the release of moisture to the atmosphere by plants.
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.
Earth contains a variety of plants to provide food, medicine and, most importantly, energy sources for humans. In this lesson, students will categorize plants by their components and shapes. Additionally, they will learn the mechanisms behind the making of medicines and bio-fuels. It is important that the students have prior knowledge of the plant cell structures and functions. The video duration is 21 minutes, during which the students will use skills such as classification and experimentation. The students must therefore be supplied with various samples of plants.

Description of the processes by which mass, momentum, and energy are transported in plasmas, with special reference to magnetic confinement fusion applications. The Fokker-Planck collision operator and its limiting forms, as well as collisional relaxation and equilibrium, are considered in detail. Special applications include a Lorentz gas, Brownian motion, alpha particles, and runaway electrons. The Braginskii formulation of classical collisional transport in general geometry based on the Fokker-Planck equation is presented. Neoclassical transport in tokamaks, which is sensitive to the details of the magnetic geometry, is considered in the high (Pfirsch-Schluter), low (banana) and intermediate (plateau) regimes of collisionality.
The purpose of this task is to have students add mixed numbers with like denominators. This task illustrates the different kinds of solution approaches students might take to such a task.
After a brief history of plastics, students look more closely as some examples from the abundant types of plastics found in our day-to-day lives. They are introduced to the mechanical properties of plastics, including their stress-strain relationships, which determine their suitability for different industrial and product applications. These physical properties enable plastics to be fabricated into a wide range of products. Students learn about the different roles that plastics play in our lives, Young's modulus, and the effects that plastics have on our environment. Then students act as industrial engineers, conducting tests to compare different plastics and performing a cost-benefit analysis to determine which are the most cost-effective for a given application, based on their costs and measured physical properties.
Students are introduced to the growing worldwide environmental problems that stem from plastic waste. What they learn about microplastics and the typical components of the U.S. water treatment process prepares them to conduct three engaging associated activities. During the lesson, students become more aware of the pervasiveness and value of plastic as well as the downstream pollution and health dangers. They learn how plastic materials don’t go away, but become microplastic pollution that accumulates in water resources as well as human and other animal bodies. They examine their own plastic use, focusing on what they discard daily, and think about better ways to produce or package those items to eliminate or reduce their likelihood of ending up as microplastic pollution. A concluding writing assignment reveals their depth of comprehension. The lesson is enhanced by arranging for a local water treatment plant representative to visit the class for Qs and As. In three associated activities, students design/test microplastic particle filtering methods for commercial products, create mini wastewater treatment plant working models that remove waste and reclaim resources from simulated wastewater, and design experiments to identify the impact of microplastics on micro-invertebrates.
