Describes a circuit by which capacitance and the dielectric constant can be measured. Shows the circuit diagram and the method to calculate these constants. (YP)

Introduces some ideas on teaching scaleup in chemical engineering. Discusses the instructional modes and the general and specific topics. Provides two examples of an experiment with equipment and safety issues. Shows the list of actual individual and team projects in an appendix. (YP)

Describes the Tardigrada as a group of animals suitable for close study in project work. Gives reasons for their suitability and an illustrated identification key. Discusses possible investigations into the ecology and physiology of tardigrades. (Author/CW)

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…

Describes the concept of a unified laboratory program in which integrated experiments are brought together from several areas of chemistry. Discusses the design and implementation of the unified laboratory at Willamette University, including lists of laboratory experiments and projects. (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…

Describes an experiment in which stretching a rubber band can be used to compare the statistical theory of rubber elasticity with its continuum mechanics counterpart. Employs the use of the equation of the state of rubber elasticity and the Mooney-Rivlin equation. (TW)

This report is one of a series of reports from a research project that focuses on the evaluation of laboratory work in secondary schools. The study focuses on 12 different laboratory tasks from the biology and chemistry courses of the Finnish comprehensive school. Secondary students (N=212) were observed during laboratory sessions and analysis of…

This lesson explores the group of buildings in West Orange, New Jersey, built in 1887, that formed the core of Thomas Edison's research and development complex. They consisted of chemistry, physics, and metallurgy laboratories; machine shop; pattern shop; research library; and rooms for experiments. The lesson explains that the prototypes (ideas…

This CD-ROM consists of simulation software that allows students to conduct countless experiments using 20 Java simulators and curriculum units that explore light and color, forces and motion, sound and waves, static electricity and magnetism, current electricity, the nature of matter, and a unit on underpinnings. Setups can be designed by the…

Laboratory experiences as a part of most U.S. high school science curricula have been taken for granted for decades, but they have rarely been carefully examined. What do they contribute to science learning? What can they contribute to science learning? What is the current status of labs in our nation s high schools as a context for learning…

Describes three methods for offering practical work for external science courses: residential sessions on campus, local centers, and use of home laboratory kits. The advantages and disadvantages of each are discussed and examples of each in operation are given. A 21-item bibliography is provided. (EAO)

A laboratory course designed to provide simulated practice experience for pharmacy students at Drake University College of Pharmacy was redesigned by restructuring laboratory schedules to provide more time, by establishing competencies to be attained, and by self-pacing. Student evaluations of the changes were highly supportive. (MSE)

Discusses procedures, theoretical considerations, and results of an experiment involving the preparation of a tetrahedral nickel(II) complex and its transformation into an octahedral species. Suggests that fundamental aspects of coordination chemistry can be demonstrated by simple experiments performed in introductory level courses. (Author/JN)
