Described is a project designed to determine the kinds and types of science laboratories located in and around Yolo County, California. Summarized are some of the sites visited by the investigator and some of the impressions of those facilities. (CW)

High-ability students in grades 3-8 received lessons in organizing a creative investigation and were then compared to control students not receiving the lessons. The most important variables predicting whether the student initiated a creative investigation were membership in the experimental group and pretreatment self-efficacy scores for creative…

Outlines the Cosmic Background Explorer (COBE) mission to measure celestial radiation. Describes the instruments used and experiments involving differential microwave radiometers, and a far infrared absolute spectrophotometer. (YP)

Court rulings have established three basic responsibilities school systems must meet in science programs: (1) inform students about the hazards they might encounter in a science class; (2) provide a safe learning environment and properly maintained equipment; and (3) ensure adequate supervision. Outlines a four-point school safety plan. (MLF)

Examines college students' perception of an interactive videodisc learning system as an alternative to the conventional laboratory for learning biology skills and concepts taught under classroom laboratory conditions. Reports that the videodisc instruction gave more experimental and procedural options and more efficient use of time than the…

Described are three experiments on the photometric, Gaussian, and image-forming properties of a helium-neon gas laser. Details of the experimental method and typical calculations with diagrams and graphs are provided. (YP)

Investigates the nature of catastrophic volcanism and the rifting process. Describes two kinds of evidence: quantitative descriptions of rock melting and a wide range of observations. Discusses examples of continent growth in the North Atlantic, India and the Seychelles islands, and the South Atlantic. (YP)

This was an experiment to test the extended discretion laboratory approach versus a guided-inquiry approach for teaching biology in a university setting. Among three criterion variables (examination, reports, and quizzes), only the laboratory report scores showed differences between groups and group-by-instructor interaction. (Author/YP)

Describes an approach to devising realistic laboratory projects to enhance research training for undergraduates. Students replicate all or part of an experiment from a core article that provides the framework for the research project in terms of scope, method, and reporting. Advantages and limitations of the method are discussed. (GEA)

Outlines a graduate course, "Microbial Systems Analysis," for students in chemical and environmental engineering or engineering mechanics, as well as microbiology, ecology and biotechnology. Describes the objectives, structure and laboratory experiments for the course. (YP)

Discusses a laboratory exercise simulating the paths of light rays through spherical water drops by applying principles of ray optics and geometry. Describes four parts: determining the output angles, computer simulation, explorations, model testing, and solutions. Provides a computer program and some diagrams. (YP)

Described is the construction and use of an osmometer that is low in cost, easy to make, and durable. Materials needed and procedures are outlined. Diagrams show an assembled instrument and individual parts. (RT)

Described is an experiment for measuring the coefficient of restitution with a meter stick, balls of different types, and scraps of material for the plates. Provides the experimental procedure and an apparatus diagram. (YP)

Makes use of distinctions between experiment and demonstrations to resolve a paradox for the sociology of scientific knowledge. Describes two public tests which illustrate these themes. Discusses types of core-set distortion and suggests a partial solution. (YP)

Discusses and suggests some solutions for three problems related to chemistry laboratory management, including disappearance of teaching assistants, check in/out procedures, and slow students. (YP)
