Explains how to use magnetic cylinders on an air table to demonstrate certain atomic structure and vibrational behavior in many face-centered metals like aluminum or copper. (GA)

Explains how physics teaching can be more relevant for elementary and secondary students by integrating physics and earth science content that students can relate to and understand. Identifies and explains Earth contexts that can be appropriately implemented into the physics curriculum such as waves, magnetism, and electricity. (Author/YDS)

Describes initial results of a collaborative action research endeavor between a university and a magnet school (grade 6 level) using learning environments research to monitor alignment of classroom learning activities with a constructivist viewpoint while integrating technology into the curriculum. Discusses use of the Constructivist Learning…

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)

Describes the Mount Washington German Magnet School in Kansas City, Missouri, a planned elementary (K-3) school that will provide students with the opportunity to participate in a German-English bilingual program. Parents choose either a total immersion or partial immersion program for students in this public, integrated school. (JL)

Describes the discovery and characteristics of superconductors. Discusses some experiments on the levitation of a magnet over a superconductor. (YP)

Describes the change of earth's magnetic field at the boundary between the outer core and the mantle. Measurement techniques used during the last 300 years are considered. Discusses the theories and research for explaining the field change. (YP)

Among the features of a good public school choice plan are (1) a clear goal statement; (2) information and counseling for parents in selecting programs for their children; and (3) admissions procedures that are fair and equitable. Cites characteristics of school choice programs in Minnesota and East Harlem, New York. (MLF)

Claims of success in Minnesota's open enrollment plan are exaggerated. Transfer requests are based on convenience and location rather than on the quality of education. Using the open market technique means that handicapped or other high risk students will be less desirable commodities. Public funding for private schools will be advocated. (MLF)

Describes the construction of a demonstration toy consisting of a rotating shaft suspended by a magnetic field with the cost being around $2. (MVL)

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)

Six articles discuss the work of Michael Faraday, a chemist whose work revolutionized physics and led directly to both classical field and relativity theory. The scientist as a young man, the electromagnetic experiments of Faraday, his search for the gravelectric effect, his work on optical glass, his laboratory notebooks, and his creative use of…

Theme articles discuss the need for agriculture teachers to heed research in science education; describe the landscape horticulture program at Anoka (MN) High School; propose a change of curriculum objectives to ones that teach students career readiness; and describe the East Environmental Science and Agri-Business Magnet High School in Kansas…

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)

Information on how a shortwave radio can be used to make empirical observations about solar activity and the Earth's geomagnetic field is provided. How to interpret transmissions of shortwave propagation information, weather conditions, and highly accurate time signals from shortwave stations is discussed. (KR)
