The author relates his successful experiment with using old time radio programs to enhance listening and writing skills in his classroom. A list of companies that sell Old Time Radio (OTR) programs, and a list of projects which can be used with OTR, conclude the article. (KC)

Presents a list of the producer, catalog number, format, and price of audiovisual aids for: acids, bases, and salts; atomic structure and atoms; biochemistry; bonds; water chemistry (solutions); changes of state; and electrochemistry. Includes a separate list of names and addresses of randomly selected producers of audiovisual materials. (SK)

Suggests ways in which chemistry professionals, particularly academic faculty members, might improve the image of chemistry and engineering. Stresses damage done to this image because of recent media coverage regarding misuse and improper disposal of chemicals. (CS)

Presents six selected middle school science notes which could be used in school science courses. Each includes the name of the author and a description of activities presented. (HM)

Describes an apparatus and procedure for conducting an undergraduate laboratory experiment to quantitatively study the Hall effect in a plasma. Includes background information on the Hall effect and rationale for conducting the experiment. (JN)

Reviews four science curriculum materials. "Human Issues in Science" presents social consequences of science and technological developments. "Experiences in Science" contains duplicating masters to supplement basic science programs. "Outdoor Areas as Learning Laboratories" includes activities for local environments. "The Science Cookbook" uses…

Describes an undergraduate experiment which measures the energy gap in silicon and germanium. Theory, procedure, and results of this experiment are included. (HM)

Discusses the simplest three-body problem, known as Euler's problem. The article, intended for students in the undergraduate mathematics and physics curricula, shows how the complex equations for a specific three-body problem can be solved on a small calculator. (HM)

Provides information regarding the extra bands of color, termed supernumerary arcs, that sometimes accompany a natural rainbow. Several experiments are described that elucidate the phenomenon of supernumerary arcs, involving the illumination of a hanging water droplet with white light from a projector or monochromatic light from a helium-neon…

The use of the computer in problem solving situations is profiled. Sample lessons for beginning, intermediate, and advanced students are presented along with possible programs for a variety of computers using BASIC. (MP)

A mathematical treatment of the relationship between driving speed and fuel efficiency is presented. The material involves applications of exponentials, logarithms, and elementary calculus, and is intended to be enrichment material for secondary and lower college mathematics classes. (MP)

Presents three simple distinct operational procedures for transforming the empirical notion of speed into a formal concept. The relationship between these three procedures and Galilean velocity and Einsteinian relativity is also included. (HM)

The need for a strong package of computer software in a computer science-oriented program is discussed. Ways of accumulating software and selective reviews of available computer assisted instruction (CAI) programs are also presented. (MP)

An activity unit designed to help students discover some of the patterns of sine and cosine functions is presented. Worksheets designed for duplication are included. (MP)

In addition to preserving the memory of one school year, high school yearbook staffs might consider creating and maintaining a reference room that contains the school's entire history. (RL)
