Students are introduced to measuring and identifying sources of air pollution, as well as how environmental engineers try to control and limit the amount of air pollution. In Part 1, students are introduced to nitrogen dioxide as an air pollutant and how it is quantified. Major sources are identified, using EPA bar graphs. Students identify major cities and determine their latitudes and longitudes. They estimate NO2 values from color maps showing monthly NO2 averages from two sources: a NASA satellite and the WSU forecast model AIRPACT. In Part 2, students continue to estimate NO2 values from color maps and use Excel to calculate differences and ratios to determine the model's performance. They gain experience working with very large numbers written in scientific notation, as well as spreadsheet application capabilities.

Analytical chemistry is the branch of chemistry dealing with measurement, both qualitative and quantitative. This discipline is also concerned with the chemical composition of samples. In the field, analytical chemistry is applied when detecting the presence and determining the quantities of chemical compounds, such as lead in water samples or arsenic in tissue samples. It also encompasses many different spectrochemical techniques, all of which are used under various experimental conditions. This branch of chemistry teaches the general theories behind the use of each instrument as well analysis of experimental data. Upon successful completion of this course, the student will be able to: Demonstrate a mastery of various methods of expressing concentration; Use a linear calibration curve to calculate concentration; Describe the various spectrochemical techniques as described within the course; Use sample data obtained from spectrochemical techniques to calculate unknown concentrations or obtain structural information where applicable; Describe the various chromatographies described within this course and analyze a given chromatogram; Demonstrate an understanding of electrochemistry and the methods used to study the response of an electrolyte through current of potential.

In 2008, the Beijing Urban Design Studio will focus on the issue of Beijing's urban transformation under the theme of de-industrialization, by preparing an urban design and development plan for the Shougang (Capital Steel Factory) site. This studio will address whether portions of the old massive factory infrastructure can be preserved as a national industrial heritage site embedded into future new development; how to balance the cultural and recreational value of the site with environmental challenges; as well as how to use the site for urban development. A special focus of the studio will be to consider development approaches that minimize energy utilization. To research these questions, students will be asked to interact with clients from the factory, local residents, city officials and experts on transportation, environment, energy and real estate. They will assess strategic options for the steel factory and propose comprehensive plans for the design and development of the brownfield site.

Students create and decorate their own spectrographs using simple materials and holographic diffraction gratings. A holographic diffraction grating acts like a prism, showing the visual components of light. After building the spectrographs, students observe the spectra of different light sources as homework.

Students find and calculate the angle that light is transmitted through a holographic diffraction grating using trigonometry. After finding this angle, student teams design and build their own spectrographs, researching and designing a ground- or space-based mission using their creation. At project end, teams present their findings to the class, as if they were making an engineering conference presentation. Student must have completed the associated Building a Fancy Spectrograph activity before attempting this activity.

Junior Lab consists of two undergraduate courses in experimental physics. The courses are offered by the MIT Physics Department, and are usually taken by Juniors (hence the name). Officially, the courses are called Experimental Physics I and II and are numbered 8.13 for the first half, given in the fall semester, and 8.14 for the second half, given in the spring.The purposes of Junior Lab are to give students hands-on experience with some of the experimental basis of modern physics and, in the process, to deepen their understanding of the relations between experiment and theory, mostly in atomic and nuclear physics. Each term, students choose 5 different experiments from a list of 21 total labs.

This is a continuation of Freshman Organic Chemistry I (CHEM 125a), the introductory course on current theories of structure and mechanism in organic chemistry for students with excellent preparation in chemistry and physics. This semester treats simple and complex reaction mechanisms, spectroscopy, organic synthesis, and some molecules of nature.

This survey chemistry course is designed to introduce students to the world of chemistry. In this course, we will study chemistry from the ground up, learning the basics of the atom and its behavior. We will apply this knowledge to understand the chemical properties of matter and the changes and reactions that take place in all types of matter. Upon successful completion of this course, students will be able to: Define the general term 'chemistry.' Distinguish between the physical and chemical properties of matter. Distinguish between mixtures and pure substances. Describe the arrangement of the periodic table. Perform mathematical operations involving significant figures. Convert measurements into scientific notation. Explain the law of conservation of mass, the law of definite composition, and the law of multiple proportions. Summarize the essential points of Dalton's atomic theory. Define the term 'atom.' Describe electron configurations. Draw Lewis structures for molecules. Name ionic and covalent compounds using the rules for nomenclature of inorganic compounds. Explain the relationship between enthalpy change and a reaction's tendency to occur.

Background for and techniques of visual observation, electronic imaging, and spectroscopy of the Moon, planets, satellites, stars, and brighter deep-space objects. Weekly outdoor observing sessions using 8-inch diameter telescopes when weather permits. Indoor sessions introduce needed skills. Introduction to contemporary observational astronomy including astronomical computing, image and data processing, and how astronomers work. Student must maintain a careful and complete written log which is graded. In this seminar we explore the background and techniques of visual observation and imaging of the Moon, planets, and brighter deep-space objects using 8-inch telescopes. (Some sample images appear in our "photo album".) Telescope work begins with visual observing, then we advance to CCD (charge-coupled device) cameras. Each class observing session meets one evening a week. Whenever weather conditions permit us to observe outdoors we do so! In cloudy weather we'll try some astronomical computing and image processing indoors instead. Either way, virtually all the work for the seminar is done during the evening sessions, so students must attend section every week in order to pass. Past experience has been that if you're really enthusiastic about hands-on out-under-the-sky astronomy, enough to be willing to deal with dressing warmly, tinkering with equipment, and committing one evening a week, 12.409 is great fun! One student wrote, "Unlike most seminars, you will earn your units and, unlike most other MIT courses, you will look forward to doing it!" But we'll be direct: 12.409 is not for everyone, and in past years many whose interest was merely casual found themselves unwilling to devote one entire evening every week to the class. If your interest is only casual then consider whether a more typical astronomy survey subject might be a better choice, since it'll have more outside preparation time that you can rearrange at your discretion and less in-class time that you can't.

This course is a continuation of Organic Chemistry I. The student will focus on four most important classes of reactions: electrophilic substitution at aromatic rings, nucleophilic addition at carbonyl compounds, hydrolysis of carboxylic acids, and carbon-carbon bond formation using enolates. The enolate portion of this course will cover the reactivity of functional groups. The student will also look at synthetic strategies for making simple, small organic molecules, using the knowledge of organic chemistry accumulated thus far. This course also introduces biological molecules, including carbohydrates, peptides and proteins, lipids, and nucleic acids, from a molecular perspective. The student will learn how chemical reactions, especially oxidation and reduction reactions, form the basis of all life. Note that in biology, the student would study the functionality of these structures by asking, 'How do they operate?' whereas in the field of organic chemistry, the student will ask: 'What are they made of?' The student will conclude this course with a unit on spectroscopy. Upon successful completion of this course, the student will be able to: Identify the chemistry and basic mechanisms of the following functional groups: ethers, epoxides, thiols, sulfides, benzene, amines, aldehydes, ketones, and carboxylic acids and their derivatives; Plan the synthesis of unsymmetrical ethers, amines, and carboxylic acid derivatives (esters, amides, etc.); Predict the product(s) of an electrophilic addition reaction involving conjugated dienes; Use the Diels-Alder reaction on conjugated dienes to form new carbon-carbon bonds and chiral centers of a desired configuration (R or S); Determine whether a molecule is aromatic, non-aromatic, or anti-aromatic; Indicate the position in which an electrophile will be added on an aromatic ring, given the other substituents present; Identify the products and mechanisms of electrophilic and nucleophilic aromatic substitution reactions; Demonstrate mastery of enolate chemistry and techniques for C-C bond formation; Plan the synthesis of simple molecules using the reactions learned throughout both the Organic Chemistry I and Organic Chemistry II courses; Describe the chemistry associated with biological molecules such as amino acids, nucleic acids, lipids, and carbohydrates; Identify different monosaccharides, disaccharides, aldoses, and ketoses, as well as reducing and non-reducing carbohydrates; Identify the twenty naturally occurring amino acids and describe the mechanisms associated with peptide cleavage and synthesis; Use spectroscopy (mass spectrometry, UV-Vis spectrometry, infrared spectrometry, and nuclear magnetic resonance) to characterize an organic molecule.
