Describes equipment, activities, and experiments useful in biology and environmental education instruction, including, among others, sampling in ecology using an overhead projector, the slide finder as an aid to microscopy, teaching kidney function, and teaching wildlife conservation-sand dune systems. (SK)

Summarizes "you do it" activities presented at the 1978 South Australian Science Teachers Association Conference. Topics include microscope use and maintenance, chemical slide cells, chemical models, sound waves, microwaves, astronomy, plant keys, reading geological maps, and natural dye processes. (DS)

Discusses methodology for several activities which use Alka Seltzer tablets as a source of carbon dioxide gas. (CS)

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)

Discusses the effect of silhouetting a vertical vibrating string against a television screen. The article also reports the usefulness of the effect in tuning stringed instruments and as a possible basis for lecture demonstrations and student discussions and investigations. (HM)

Describes an experiment for the use of a tilted plane as a two-dimensional uniform gravitational field to demonstrate the motion of projectiles, to determine the fundamental laws of mechanics, or to study the focusing properties of the uniform field. (SK)

Described are several activities to be used to help students grasp the concept of floating. The activities include the use of a spring scale to measure the weight of the objects in air, in water, and in salt water, and a discussion of why there are differences in these weights. (DS)

Describes an introductory physics laboratory course, used at the University of California in Berkeley, designed to teach students some general intellectual skills. Results of the course evaluation are also discussed. (HM)

The application of principles learned in a first course in chemistry to chemical problems of interest to home economics majors specializing in clothing and textiles or fashion merchandising is described. Concept transfer--teaching difficult concepts in terms of an everyday analogue--is also explained and relevant laboratory experiments are…

This experiment demonstrates the reduction of inorganic sulfate to sulfide in the pore water of estuarine muds. Procedures involve the incubation of mud samples for varying amounts of time followed by gravimetric determination. (Author/SA)

Describes an experiment, designed for use in the undergraduate laboratory, that measures the bond energies of molecules using a small commercial mass spectrometer and low-cost digital voltmeters. (BT)

Presents seven selected middle school science activities which could be used in school science courses. (HM)

Describes a project designed to increase science literacy in the general public by bringing hands-on experiments with real-world applications to public school students. Provides the history and an outline of the program. (DDR)

Describes the design of several CD-ROMs with different strategies and foci for teaching general chemistry with large databases of visual information. Presents a sample search with a CD-ROM. Discusses teacher resources including animations, visual databases for presentations, demonstration manuals, laboratory manuals, and encyclopedias as well as…

Presents four Physics General Certificate of Secondary Education assessment practicals which can be photocopied for use in instruction. Includes notes for guidance of teachers in determining student skills in management and organization, designing and carrying out experiments to solve problems, draw conclusions, and select suitable apparatus for…
