Describes a program offered by the U.S. Department of Energy for undergraduate science and engineering students aimed at providing research experience during the academic year at the six national laboratories. Reviews the potential interest and benefits to students. (CW)

Describes the use of student journals in a liberal arts chemistry class taken as part of the general education requirements by nonscience majors. Discusses the structure, grading, process, and benefits of the journal and its use in the course. (CW)

Describes three activities, substrate inhibition, product inhibition by fructose and glucose, and gel immobilization of invertase for use with undergraduate biochemistry classes. Discusses materials, methods, and results. Stresses the advantages of practical exercises in undergraduate classes. (CW)

Gives some ideas for studying and growing crystals in the classroom and home as well as some background information to help integrate these ideas into an existing science curriculum. Discusses three activities including common household materials and laboratory procedures. (CW)

Reports a classification of expository teaching styles of biology, chemistry and integrated science teachers in Nigeria. No evidence was found of pupil-pupil interaction in any of the lessons observed. Compares results with other studies from Britain, Canada, and Indonesia and indicates significant differences. (CW)

Discusses the need for a college chemistry course that is directly applicable to the real world. Describes some of the facets that such a course would contain and some of the possible benefits to students. (CW)

Compares processes used to investigate issues in consumer chemistry to the solving of a puzzle in a mystery story. Suggests using similar methods to teach problem solving in consumer chemistry classes. Describes how such a process might progress. (CW)

Describes a one-semester course in environmental chemistry for students who have had a full year of introductory level chemistry. Illustrates how material from this upper-level course was integrated into a general chemistry course. Examples of content are provided. (CW)

Describes a demonstration procedure using controlled reduction potentials to predict observed color changes which are then experimentally verified. Demonstrates the usefulness of this procedure in helping students understand LeChatelier's principle and the solubilit rule "like dissolves like." (CW)

Described is a report outline for geologic reports. Essential elements include title; abstract; introduction; stratigraphy; petrography; geochemistry; petrology; geophysics; structural geology; geologic history; modeling; economics; conclusions; and recommendations. (Author/CW)

Describes the trend toward the use of electronic instrumentation to monitor and measure various parameters in chemical reactions. Stresses that a knowledge of the operational relationships involved in such instruments is essential for students beginning in science. Discusses electrostatic charges, semiconductor crystals, electronic conductors,…

Investigates the effects of using scientific apparatus versus household objects on the accuracy of primary school children in a simple titration exercise. Indicates no significant difference between the accuracy obtained using the two types of apparatus at the beginning, but improved performance for children using scientific apparatus by the end.…

Describes a new laboratory technique for working with small samples of compounds used in nuclear magnetic resonance (NMR) analysis. Demonstrates how microcells can be constructed for each experiment and samples can be recycled. (TW)

Describes a quantitative experiment designed to demonstrate buffer action and the measurement of buffer capacity. Discusses how to make acetate buffers, determine their buffer capacity, plot the capacity/pH curve, and interpret the data obtained. (TW)

Reviews the status of chemical engineering and the chemical industry in the United States. Identifies problem areas for engineers and proposes new directions for chemical engineering courses. Discusses the significance of these new directions for bachelor's degree programs. Proposes that the function of a bachelor's degree should be general…
