A simple apparatus for studying various forms of the aurora borealis on a miniature scale can be constructed from a neon-storage flask, aluminum tape, a cardboard box, and a small piezoelectric ion gun of the type used to neutralize static charges on phonograph records. (PR)

Snow is a widely available earth-science teaching medium which can be used to explore scientific concepts in the field, either directly or by analogy. Snow can be considered a mineral, sediment, sedimentary rock, or metamorphic rock. Natural processes such as crystal growth, melting, sedimentation, and metamorphism can be studied in practical time…

Describes activities to help students see discontinuities as faults. Students collect data, manipulate data, and use the data to formulate explanations. Schematic diagrams help students with the conceptual component of thinking. (PR)

The Comprehensive Unified Physics Learning Environment is a computer system using computer programs, interactive videodisks, and electronic sensors being developed at the University of Maryland. The method has been found more effective than traditional ones for teaching physics majors and is being used to modify the conventional course for…

The outcomes of two studies reported here indicate that the teacher inservice workshops, combined with activity-based science lessons, affected students' attitudes and perceptions about electricity. Australian and U.S. studies produced different patterns and are explored and explained in the paper. (Contains 24 references.) (Author/PR)

From respondents to a questionnaire sent to a random sample of 654 Texas biology teachers, the following conclusions were made: 86% agreed evolution should be taught, 47% agreed it was a central theme in biology, 8% indicated that it conflicted with the Bible, and 7% noted there were more useful alternative theories explaining the history of the…

Describes the activities of the Salish consortium, a group of people who are interested in developing and researching collaborative models of science teacher preparation and development. The consortium will focus on the preparation of science teachers as defined by the emerging U.S. National Science Education Standards and Assessment. (PR)
