Discusses the relationship of taste and smell to ingestion, digestion, and metabolism. Indicates that the response of these physiological systems can be chemical specific and that chemical senses may play different roles in regulating diet during nutrient deficiency and during nutrient surplus situations. (JN)

Suggests chemistry of cooking and analysis of culinary recipes as subject matter for introducing chemistry to an audience, especially to individuals with neutral or negative attitudes toward science. Includes sample recipes and experiments and a table listing scientific topics with related cooking examples. (JN)

Discusses the availability of proteins, carbohydrates, lipids, vitamins, and minerals in processed food. (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)

Presents a problem on nonstandard concentrations at nonstandard temperature modeled after an example problem on the Nernst equation found in a high school chemistry textbook. Discusses why the problem is incorrect, offering a second problem which is correctly solved. Implications for teaching the Nernst equation are considered. (JN)

Describes an electronic thermometer using a precision temperature sensor (includes detailed schematic of circuits) and inexpensive ring holders for round-bottomed flasks. Also describes a method for reducing funnel breakage. (JN)

Safety procedures used by Department of Chemistry at the University of Akron are discussed. These include policy that no chemicals are stored in the teaching laboratories. Instead, dispensing stockrooms are used to service the laboratories. Other aspects discussed include ventilation procedures and development of microprocessor use in stockrooms.…

Outlines several ideas on introductory electrochemistry material suitable for college-level general chemistry. These include discussions of conductivity in solids and electrolytes, electrical quantities/properties, electrode potentials, and membrane potentials. Indicates that whatever strategy is used to present this material, the presentation…

Addresses concepts about electrochemical systems that cause confusion among those new to the subject. The goal is to synthesize an understanding of the heterogeneity of an electrochemical system and a chemical sense for the important electrochemical variables of potential, current, and charge. (JN)

Suggests various methods for teaching the double layer in electrochemistry courses. Topics addressed include measuring change in absolute potential difference (PD) at interphase, conventional electrode potential scale, analyzing absolute PD, metal-metal and overlap electron PDs, accumulation of material at interphase, thermodynamics of electrified…

Provides a prospective on electrosynthesis technology for chemical educators and students by discussing electrosynthesis reactions and experiments. Includes tables illustrating some electrochemical products, variables to consider in electrochemical reactions, indirect electrolysis of organic compounds, examples of direct/indirect electrochemical…

Four examples of industrial electrochemical synthesis of organic compounds are described. These include acrylonitrile dimerization, tetramethyl lead, electrochemical fluorination, and production of diacetone-2-keto-L-gulonic acid. Additional examples are also cited, including the production of several compounds by the BASF company of Germany. (JN)

Discusses engineering ramifications of electrochemistry, focusing on current/potential distribution, evaluation of trade-offs between influences of different phenomena, use of dimensionless numbers to assist in scale-over to new operating conditions, and economics. Also provides examples of electrochemical engineering education content related to…
