Presents background information on nitric acid including old names, history, occurrence, methods of preparation, uses, production, and price. Includes such chemical properties as decomposition; acidity, oxidation of metals and nonmetals; reactions with organic and inorganic compounds; gaseous fluorine; and nitrating properties. Also discusses bond…

Presented is the full American Chemical Society (ACS) report on the number of bachelor's, master's, and doctoral graduates in chemistry and chemical engineering. Includes a complete list of degrees awarded by institution. Indicates that although bachelor's and master's degrees have increased, the number of master's degrees awarded has decreased.…

Proposes an approach to chemical kinetics and mechanism using statistical games, illustrating its use in monomolecular, catalytic, autocatalytic, consecutive, and equilibrium reactions. Major features of the games are also outlined and discussed. (JN)

Because class size often limits student opportunity to handle individual models, teachers use stereoscopic projections to demonstrate structural features. Describes three-dimensional pointers for use with different projection systems so teachers can indicate a particular atom or bond to entire classes, avoiding the perspective problems inherent in…

Discusses instructional strategies and activities designed to help students learn to recognize patterns and to create models to explain patterns. These include laboratory investigations and an exercise in which students are challenged to find the model used for the classroom seating arrangement. (JN)

Background information (including optical properties of inorganic materials) and procedures are provided for an experiment which introduces students to preparation of a doped semiconductor; phosphorescence; gettering procedures; reducing atmospheres; and use of a high-temperature furnace with associated thermocouples, temperature controllers, and…

Discusses: (1) the conflict about the importance of research at predominantly undergraduate schools; (2) sources of funding for undergraduate research (several of which are targeted at predominantly undergraduate institutions); and (3) undergraduate research at doctoral-granting institutions. (JN)

Describes an apparatus developed for photochemical studies, particularly those involving the fluorescence of halogenated acetones. The apparatus is constructed from equipment normally found in a moderately sized physical chemical laboratory. Also provides background information on some aspects of the photophysics of halogenated propanones. (JN)

Findings from an American Chemical Society survey show that the pessimism that characterized the job market in 1983 has given way to a much brighter outlook as employers hire more chemists and chemical engineers. Data from the survey on the supply and demand of chemical professionals are provided and discussed. (JN)

Highlights efforts to increase high school use of chemical industry resources. Indicates that a list of industry resources available to all Philadelphia (PA) area chemistry teachers is currently available from the American Chemistry Society Corporation Associates. (JN)

Compared performance of Syracuse University Project Advance (PA) chemistry students (N=35) with advanced placement (AP) candidates on the AP chemistry examination. PA students scored slightly above the national average on the examination, and students who performed well (B or better) in AP chemistry also did well on the examination. (JN)

Project Advance is a high school chemistry program equivalent to chemistry taught on the Syracuse University campus. A survey reveals that teachers in general have positive attitudes and good impressions of the course. Positive attitudes and high regard for the experience were also noted by students completing the course. (JN)

Discusses major events leading to the development of the octet rule. Three conclusions based on the work of Mendeleev, Abegg, Thompson, Kossel, Lewis, and Langmuir are considered as is the debate over the rule's validity. (JN)

Discusses seven key concepts in Ausubel's learning theory which function to guide research and teaching. Also discusses concept mapping and Gowins Vee, providing examples of how they are used in chemistry instruction. (JN)

Project CHEMLAB has prepared a database which focuses on laboratory experiments suitable for high school through graduate or professional school levels. The scope of the project, the structure of the database, database features, and computer searching are discussed. (JN)
