Describes a unit on the physical properties of minerals. The unit, based on the learning-cycle approach, encourages students to move from single to more complex reasoning patterns. Concepts fostered are orderlines, quantification, and replication. (JN)

"Computerevolution" is described as the evolutionary change produced by the introduction of computer technology--an action that is producing complex changes in the culture of Californians. The state of the art of computerized education in that state is summarized. (JN)

To discover how misconceptions occur and how teachers deal with them when they occur, fifth-grade students (N=229) and teachers (N=14) were observed during units on light and photosynthesis. Results suggest that curriculum developers consider childrens' misunderstandings of phenomena and design materials explicitly contrasting these…

Young children are naturally curious about their environment and learn best by exploring the world around them. Magnifiers, or hand lenses, are a valuable tool in this exploration. Discusses the selection, use, storage and costs of magnifiers. Includes suggestions of objects/phenomena to observe inside and outside of the classroom. (JN)

On June 13, 1983, the U.S. unmanned spacecraft, "Pioneer 10," will cross the orbit of Neptune. This first flight beyond the planets is being celebrated by the National Aeronautics and Space Administration and other groups. Discusses what the spacecraft will observe and types of data it will collect. (JN)

Describes a genetics activity illustrating genetic variation, mutation, and influence of environmental factors on genotypic expression. Irridiated bean seeds are planted and observed (x-rayed by dentist's x-ray machine at different exposures and for different times). Questions to extend the activity are discussed. (Author/JN)

The absence of "hands-on" experiences with science equipment in schools stimulated the production of science kits for children. Thirty years later this enterprise has become a national institution in Brazil with a proud history of effecting change in the teaching of science throughout this country. (Author/JN)

Children will be able to see the concept of a magnetic field translated into a visible reality using the simple method outlined. Standard shelf paper, magnets, iron filings, and paint in a spray can are used to prepare a permanent and well-detailed picture of the magnetic field. (Author/JN)

Guidelines to foster creativity in elementary/middle school students are discussed. These include understanding the creative process, freeing the classroom from constraints, rewarding creative behavior, modeling creative behavior, deferring judgment, choosing appropriate subject matter/materials, and using activities stimulating creativity.…

Reviews "Earthquakes and Volcanoes" (grades 3-6), "Metric Football" (a game), and "Happy Metrics I and II" (grades 4-6). Includes format, nature of activities, source, price, and reviewer's comments. (JN)

Middle junior high school science activities focusing on snow are suggested. These include observing snowflakes, measuring snow, examining relationship between snow and temperature, and activities related to drifting snow and snow fences. (JN)

Several new objectives for science education are discussed as a means of categorizing research findings. They include: definition, accommodation, oversimplification, exemplification, association, and representation. The objectives will require new styles of verbal interaction between science teachers and their students. (Author/JN)

Building bankhides (areas for trout to rest, hide from predators, and wait for their next meal) is one project of the Bettendorf (Iowa) Community School District's K-12 field science programs. Discusses sixth graders involvement and related activities in the bankhide project. (JN)

Describes an alternative method for using live animals in the classroom. A toy dog, the "Trail Tracker Hound Dog" (manufactured by CPG Products Corporation, Cincinnati, Ohio), is used to encourage development of such skills as observation, hypothesis testing, and collection and analysis of scientific data. (Author/JN)

Found at the summit of some of the highest peaks of New York State's Adirondack Mountains are low-growing plants similar, and in many cases, identical to plants growing in the Arctic. Describes these plants and the environment in which they are found. Includes a color plate of alpine tundra plants. (Author/JN)
