Brief comments on the topic of safety in the classroom and field, a technique for demonstrating the three-dimensional nature of a magnetic field, and a method for stimulating student interest in science films. (JR)

Presented is a demonstration of magnetostatic image poles in the presence of ferromagnetic materials. The experimental set up and probable results are discussed. Real and image systems are illustrated. (CW)

A quantitative application of magnetic braking performed with an air track is described. The experimental measurement of the position of the glider as a function of time is calculated. (KR)

Presents ideas to help elementary school educators teach their students about magnetic force fields by observing how iron filings line up around magnets. The article lists materials needed and offers a student page with suggested student activities. (SM)

As the number of new schools explodes in urban centers, educators need to understand the processes and challenges faced by schools trying to develop a central focus for curriculum and instruction. Using case study methods including interviews and document analysis, the current study explores the ways in which a highly successful magnet high…

We describe our experience in building a remote laboratory for teaching magnetic domains. Fulfilling the proposed on-line experiments, students can observe and study magnetization processes that are often difficult to explain with written material. It is proposed that networks of remotely accessible laboratories could be integrated in the Global…

At the start of each school year at Oil City Elementary Magnet School in Oil City, Louisiana, eager students ask, "What's our theme this year?" This curiosity comes from their expectations that they will study a different environmental concept each year. Kindergarten classes learn to "Be a Friend to the Earth," followed by life…

This publication presents the background, support documents, and the accompanying 16 units needed to teach electricity and magnetism to fifth grade students. Included are materials lists, a discussion of the use of process skill terminology, a list of unit objectives, a vocabulary list, background information for teachers, and the 16 units. Topics…

Presents low-cost learning activities to help teach elementary students about the earth's magnetic field. One project has students make a model of the earth's magnetic field. Another has them experiment with magnetism. (SM)

Describes the history of Richard Blakemore's discovery of magnetotaxic organisms. Discusses possible reasons why the magnetic response in bacteria developed. Proposes research experiments integrating biology and physics in which students investigate problems using cultures of magnetotaxic organisms. (MDH)

The report describes use of the Slingerland teaching approach with language handicapped students in a magnet elementary school at Chula Vista, California, and offers guidelines to school systems interested in implementing the Slingerland approach in specific magnet schools. The development of the program is briefly traced, characteristics of…

Ecological, interdisciplinary, and interconnected laboratory lessons focusing on magneticism: (1) producing electric power; (2) magnetics and magneticism; (3) electomagnetism (2 parts); and turbines (2 parts). Lessons, designed as precursor for students to make choices in electricity production, use a directed inquiry approach. (MCO)

In spite of a widespread commitment to the comprehensive high school, the nation has long had specialty or theme schools and schools that target particular children. Magnet schools, alternative schools, and Catholic schools illustrate that the idea of specialized schools is not new. Recently, the concept has received a boost from a study by the…

Shows that the mutual repulsion that enables a superconductor to levitate a magnet and a magnet to levitate a superconductor can be combined into a single demonstration. Uses an overhead projector, two pellets of "1-2-3" superconductor, Nd-Fe-B magnets, liquid nitrogen, and paraffin. Offers superconductor preparation, hazards, and disposal…

Discussed are the division of labor, defenses, genetics and evolution, communication, and navigation power of honeybees. The scientific and cross-curricular themes that can be offered using the economically important honeybee are described. Research that suggests that bees may be flying magnets is also discussed. (KR)
