Presents nine selected chemistry notes which could be used in school chemistry courses. Each includes the name of the author, a description of activities suggested and a list of references. (HM)

Factors that influence the efficiency of laboratory experiences include: size of laboratory group, length of session, discussion, special tools, and applications of knowledge learned. It is suggested that these variables may be altered to insure that students gain from their time spent in the laboratory. (BH)

Explains two approaches to the automatic arrest of a potentiometric titration. (SA)

Presents two elementary and two secondary teaching strategies related to food and energy as global issues. Includes making a survey on energy use, an exercise about food, society, and technology, an energy and a water survey, and discussion and experiments concerning food and technology. (CK)

Seven suggested activities for use in biology classrooms are described. (HM)

Presents thirteen selected chemistry activities which could be used in school chemistry courses. (HM)

Presents five selected physics activities which could be used in school physics courses. (HM)

Discusses the future of chemical research in the 1980s and the important improvements that will probably occur, particularly in the chemical industry. (SA)

Presents part two on the use of the detection of thermoluminescence as an analytical tool for the chemistry laboratory and allied science. This part discusses instrumentation used and investigates recent developments in instrumentation for thermoluminescence. (HM)

Presents a discussion for the principles of a Fourier Transform infrared spectrophotometer which is intended to provide chemists with a basic understanding of these principles. (HM)

Discusses the cognitive outcomes of physics laboratory exercises and suggests three types of experiments which should be added to those normally used in physics courses. (HM)

An elementary science teacher's technique for stimulating children to think visually, is presented. Through the medium of magic, children are given opportunities to form mental images to explain certain phenomena in science class. (SA)

Describes a physics laboratory for college students, in which the students participate in a firsthand noninertial experience. The equipment and problems are described. (SA)

The hazards associated with recombinant DNA research are presented along with some social implications and the development of recombinant DNA research guidelines by the National Institutes of Health. (SA)

Evaluates the value and effectiveness of college science laboratory instruction. An observational system called the Science Laboratory Interaction Categories (SLIC) was used to assess the performance of students and instructors in introductory and advanced laboratories of a large midwestern university.
