Describes a versatile mount for Slinky wave demonstrator and dynamics experiments using pool balls which have been altered by various means such as hollowing out or filled with lead. Suggests tightening screw holding motor clamp to prevent random speed fluctuations in ripple tanks. (JN)

Federal government's and scientists'/engineers' viewpoints on governmental efforts to control flow of scientific/technical information are presented, including controls at hand, alternative control mechanisms, voluntary controls, and controls being fostered by the Department of Commerce. (SK)

Summarizes research funding issues and concerns discussed at a symposium on government and industry support for university research. Describes efforts by the Council for Chemical Research, a combined university-industry organization, to generate funds and to improve communication between academic and university scientists. (DC)

Describes a self-paced undergraduate environmental science course focusing on a theme that earth is similar to a spaceship inasmuch as: (1) both possess finite room and resources, and (2) living things are dependent upon life-support systems for continued survival. Includes a list of laboratory and learning activities. (DS)

Describes a method to allow direct observation of a chick embryo development from three days to about 17 days of incubation, by culturing the entire embryo in a petri dish. (DS)

An observational instrument called the Laboratory Interaction Categories-Student (LIC) is described. The LIC is an easily understandable and usable tool for assessing pupil laboratory performance. (MP)

Describes ways platyfish can be utilized in biology activities and experiments. Includes an account of the animals' care, unique anatomical characteristics, reproductive behavior, and genetics. (DS)

Provides examples of several classroom activities utilizing the American horseshoe crab (Limulus Polyphemus), including raising fertilized eggs, fertilizing eggs in vitro, and testing water samples. Includes background information on the natural history, life cycle, and breeding habits of this animal. (DS)

Describes a three-hour, one-semester graduate course to provide numerical methods and modeling techniques to handle problems in future courses or engineering practice. Includes rationale for topics such as interpolation, integration, and equation roots, among others. Indicates that all problems require computer use. (SK)

Described is a computer program which accepts face data, performs all necessary symmetry operations, and produces a drawing of the resulting crystal. The program shortens computing time to make it suitable for online teaching use or for use in small computers. (Author/DC)

Supported by this experimental study was the hypothesis that science process skills of premedical and predental students could be improved by a semester-long course modeled after the AAAS Science - A Process Approach curriculum. Recommendations are made regarding the inclusion of science process skills in college science courses. (CS)

Data gathered from a national survey mailed to 55 industries employing large numbers of technical personnel support the notion that the employment market should be broadened for persons receiving their academic training in physics. Alternative curriculum strategies and course subjects are suggested for preparing physicists for industrial…

Reviews the work, experiences, and views of Dennis L. and Donella Meadows, past-principal investigators of the "Limits to Growth" study. Focuses on current "Limits" work at Dartmouth's Resource Policy Center founded by D. L. Meadows with National Science Foundation support. Core activity at the Center is modeling for policy…

Results of three studies comparing lecture/discussion to a Personalized System of Instruction (PSI) suggest that students perform better using PSI. (SK)

Describes a Simple Huckel Molecular Orbital (SHMO) computer program written in BASIC and suitable for use on a variety of common microcomputers. (SK)
