Describes four science experiments relating to energy developed for interdisciplinary general science courses. (SL)

Described is a school project to investigate aggregations in flatworms which may be influenced by light intensity, temperature, and some form of chemical stimulus released by already aggregating flatworms. Such investigations could be adopted to suit many educational levels of science laboratory activities. (DS)

Described is a diffusion apparatus to be used in an undergraduate physical chemistry laboratory experiment to determine the diffusion coefficients of aqueous solutions of sucrose and potassium dichromate. Included is the principle of the method, apparatus design and description, and experimental procedure. (Author/DS)

Described is a science experiment involving the isolation and study of microorganisms. Bacteria from the mouth are cultured on blood agar culture plates and are then exposed to four different mouthwashes to test their effectiveness. (DS)

Described is an experiment used in an undergraduate biochemistry laboratory involving inducing rickets in chicks and correlating the disease to a reduction in vitamin D-dependent calcium binding protein. Techniques involved are hormone induction, protein isolation, and radioisotope methodology. (Author/DS)

Described is an experiment designed to provide an experimental basis for a unifying point of view (utilizing theoretical framework and chemistry laboratory experiments) for physical chemistry students. Three experiments are described: phase equilibrium, chemical equilibrium, and a test of the third law of thermodynamics. (Author/DS)

Describes a year long laboratory program for third, fourth, and fifth graders. States the goal of the program is to demonstrate what chemistry is, how it is done, and why it is fun and interesting. Provides a syllabus of the experiments and lists educational objectives. (MVL)

Many teachers and other educators have expressed a concern regarding the lack of student interest in many of the traditional science courses. Concerns have also been expressed by teachers of their dissatisfaction with much of the lecture material and the laboratory exercises in some science classes. To help rectify this problem a collaborative…

Presented is an activity in which students use a microscope to do a forensic hair comparative study and a medullary classification. Mounting methods, medulla types, hair photographs, and activities are described. (DS)

This article gives examples of science teaching for gifted students from the Young Persons' Institute for the Promotion of Art and Science in Tel Aviv (Israel). Emphasis is on fostering curiosity and experimentation. Examples are offered in teaching about the weather, water, and light and color. A model experiment to teach electricity principles…

Reports the results of a survey of graduates, employers, and instructors of engineering technology programs for the essential topics in mechanical engineering technology, mechanical drafting/design technology, manufacturing engineering technology, and industrial engineering technology. Identifies the proficiency level suggested for classwork and…

Describes a course for science education majors that explores the uses of computer-interfaced experiments in a variety of interesting activities. Several examples of biology experiments are given. (ZWH)

Presented is a bibliography of articles published in the "Journal of Chemical Education" (1968-1983) which focused on industrial chemistry. Items are listed under these headings: real world of industrial chemistry; industrial notes; subject matter articles; industrial chemistry experiments/demonstrations; academic-industrial interface;…

Describes a one-semester biochemistry course designed for students who have completed courses in biology, CHEMStudy chemistry, and physical science. Course goals include presenting biochemical concepts (in preparation for college courses), challenging students considering science-related careers, and serving as a springboard for science fairs. (JN)

A science and social studies unit developed around rosin is described. Students develop an understanding of the processing of raw material from a plant source into a commercial product and how to protect wood from weathering by preparing, testing, and evaluating varnish and shellac for their wood protective qualities.
