Describes a simulation in which students play roles of computer parts. Also describes cartesian divers and eye imagers prepared from empty detergent bottles and old 35-mm film cans respectively. Suggests using the divers and imagers as free give-aways during meetings or workshops. (JN)

Techniques for examining terrestrial and aquatic microorganisms using flattened glass capillaries are described. Capillaries can be left in natural or artificial environments for appropriate periods of time and removed for direct microscopic examination. Examples of organisms observed using the technique are given and suggestions made for wider…

Describes class projects involving astronomical photography. Includes a description of how to make an astrocamera or convert a pocket camera into one suitable for astrophotography, film choices, and phenomena to photograph, such as star trails, meteors, the sun, and the moon. (DS)

Outlines laboratory procedures, demonstrations, teaching suggestions, and content information related to chemistry. Topics include polarizing power; calorimetry and momentum; microcomputers in school chemistry; a constant-volume dispenser for liquids, floating magnets, and crystal lattices; preparation of chromium; and solvent polarity and…

Describes a 10-step model for analyzing lessons involving data processing, including a set of activities for early elementary and middle school grades. Each set provides examples of relevant questions, directions, and explanations. (Author/DC)

Proposes the use of schoolyard activities as a viable alternative to extended field trips for field investigations in biology. Describes and provides examples of different approaches including a problem oriented technique, Outdoor Biology Instructional Strategies (OBIS), and a sourcebook sponsored by the Council for Elementary Science…

Describes an interdisciplinary classroom activity to explain the effect of the ocean on local weather incorporating principles from physics, chemistry, mathematics, and meteorology. (DS)

Explores several options and advantages of using microcomputers in science teaching. Describes programs for calculating pH, Maxwell-Boltzman distribution of velocities in a gas, atomic orbitals, and lattice energies. Also suggests use of microcomputers in the areas of simulations, scoring tests, and controlling stock. (DS)

Provides directions for constructing a wooden or metal weather vane. Also describes the construction of a "Boomerang Drum," a machine which can store and release energy, and suggests activities for use with it. (DS)

Provides historical background for computer usage in education. Describes several aspects of technology emerging today which will have impact on education including: the emergence of the personal computer; communication technologies; and software engineering. Also describes several simulation packages for use in the science classroom. (DS)

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 impressions of primary science activities in the United Kingdom, including student assessment, curriculum materials development, teacher development and support, and school implementation of science at the primary level. (DS)

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)

Operation Waste Watch is a seven-unit program for grades K-6 which addresses such topics as litter control, recycling, and resources recovery. It is designed to instill in students positive feelings about the environment. (DS)

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