Describes a technique for the projection of triple point demonstrations using apparatus constructed out of Lucite and an overhead projector. (GS)

Describes an approach which begins with observations and systems familiar to the student and proceeds to develop and test models to explain them. Experimental topics include Brownian motion, a germinating cell, phase change of p-dichlorobenzene, extension and contraction of rubber, and an enzyme system. (GS)

Describes a course designed to teach the fundamental microbiological principles common to all disciplines. The course is designed to meet individual student needs through self-directed lab work and various minicourses on topics in applied microbiology. (GS)

Outlines the problems and attempted solutions leading to the structure of a first year interdisciplinary science course. Presents the history and development of the course, staffing procedure, and structure of the course. (GS)

Emphasizes the simplicity and elegance of early discoveries related to the hydrogen spectrum and provides an elementary experimental basis of quantum theory based on a "numbers game" which can be played by students. (Author/GS)

Describes an investigation involving acid hydrolysis and using both volumetric and kinetic techniques. Presents examples of the determination of the rate constant and its variation with temperature. (GS)

Reviews, summarizes, and evaluates the research on audio-tutorial (A-T) instruction and attempts to provide some direction for future studies. Studies reviewed are grouped by type and include comparative methods studies, trait-treatment interaction studies, and studies of instructional variables. (GS)

Presents an idea for office hour scheduling to increase instructor accessibility, describes a television series that serves as a basis for a nationwide credit course, and describes steps taken to individualize general chemistry at Catonsville Community College, Maryland. (GS)

Describes the use of a set of 38 mm polystyrene spheres on which are marked the symbols for the elements in consecutive pairs to familiarize students with periodic classification and to illustrate relationships between quantum numbers. (GS)

Describes a model in which a steel ball bounces in synchronism with a vertically oscillating piston. The period of oscillation can be varied over a 3:1 range with the amplitude kept constant. As the period is increased, the ball bounces higher, contrary to the intuition of most observers. (Author/GS)

Includes a syllabus for lecture and laboratory in a course emphasizing principles of operation rather than trouble shooting. (GH)

Describes a survey of experiments including a stringed instrument experiment and discusses other instructional uses of cartridges. Includes information on the characteristics of cartridges. (GH)
