Refutes the view that two capacitors in series with a source of constant voltage carry identical charges. Provides experimental procedures to verify this claim. (YP)

Describes a laboratory demonstration that illustrates principles of miscible displacement and chemical retardation in soils. Discusses how the experimental apparatus can be constructed from readily available materials. (TW)

Discussed are field analyses of data involving paleocurrent directions using a goniometer and special programs for a pocket computer. States that on-site evaluation can provide immediate realization and verification of anomalous results. Includes computer programs and directions for building a goniometer. (CW)

This study of 87 veterinary medical students at Auburn University tests the effectiveness and student acceptance of interactive videodisc as an alternative to animal experimentation and other traditional teaching methods in analyzing canine cardiovascular sounds. Results of the questionnaire used are presented, and benefits of interactive video…

Discusses the need for student experiments involving the complete characterization of "unknown" inorganic compounds. Describes a project employing a complex metal compound. The compound contains six different components in both inert and labile complexions. Outlines the complete procedure and the preparation of the unknown compound. (TW)

Describes Clemson University's Advanced Engineered Fibers Laboratory, which was established to provide national leadership and expertise in developing the processing equipment and advance fibers necessary for the chemical, fiber, and textile industries to enter the composite materials market. Discusses some of the laboratory's activities in…

Discusses some of the ways that a cabbage can be used to produce a universal indicator of pH. Describes the methods for producing the indicator, experiments students can do on ordinary household chemicals, and a student take-home assignment for producing pH indicators. (TW)

Describes a chemistry lab experiment in which a microcomputer is used to graph data. In the experiment a catalyst is used to decompose a commercial bleach. The computer's game port is used with a potentiometer to plot the volume of oxygen gas produced versus elapsed time. Courseware information is included. (TW)

Discusses role of computer simulation in complementing and extending conventional components of undergraduate engineering education process in United Kingdom universities and polytechnics. Aspects of computer-based learning are reviewed (laboratory simulation, lecture and tutorial support, inservice teacher education) with reference to programs in…

Twelve articles provide practical information for high school librarians computerizing their libraries, including suggestions for purchasing software and hardware, planning and managing a computer laboratory, and using computers for student instruction and for library procedures. A suggested basic software collection for the secondary library…

Discusses how to address the concept of chemical equilibrium through the use of thermodynamic activities. Describes the advantages of setting up an equilibrium constant in terms of activities and demonstrates how to approximate those activities by practical measures such as partial pressures, mole fractions, and molar concentrations. (TW)

Provides three descriptions of demonstrations used in various chemistry courses. Includes the use of a simple demonstration model to illustrate principles of chromatography, techniques for using balloons to teach about the behavior of gases, and the use of small concentrations of synthetic polyelectrolytes to induce the flocculation hydrophobic…

Proposes a two-stage experimental approach that combines preparative chemistry and polymer characterization. Describes the simple organic synthesis of a plasticizer, the dioctylphthalate, and its direct use in the preparation of a styrene/divinylbenzene network copolymer. Discusses how to evaluate the physical properties of the resulting plastic.…

Describes the Clinton (MA) secondary school program in plastics technology, which involves (1) mostly 10th graders in a combination classroom-hands-on-activities laboratory program, and (2) 11th and 12th graders in laboratory research/ shadowing/job performance program. Also describes actual laboratory projects, program graduate job placement, and…

Describes a Memphis State University program in which faculty and staff are given inservice training in personal computing. Course subject matter content is outlined and results of a survey of the course's first participants are discussed, including most and least valuable seminar factors, and uses made of what was learned.
