Describes how Tinkertoy parts can be use to aid in helping students understand the application of Gauss' Law. (ZWH)

Presents an easy method to demonstrate Third-Law interactions using identical button magnets sliding along a smooth (nonmagnetic) knitting needle. Explains the gravitational and magnetic interactions in the case of horizontal and vertical positions of the needle. (JRH)

Describes a simple, inexpensive system that allows students to have hands-on contact with simple experiments involving forces generated by induced currents. Discusses the use of a dynamic force sensor in making quantitative measurements of the forces generated. (JRH)

Presents detailed teaching plans for activities with "rubberized" magnets as well as background information and alternative teaching-learning approaches. This activity may be used to develop student skills in inferring and in observing evidence of interaction. Includes instructions for equipment construction. (BR)

Shelve the textbooks the next time you conduct a study of magnetism and pull the concepts together with plenty of well-plotted discovery activities. Discusses a number of stimulating scientific experiments utilizing the magnet. (Author/RK)

Ordered to desegregate, the Lowell (Massachusetts) Public Schools followed parent wishes and successfully provided a variety of magnet schools to encourage voluntary desegregation. Creation of these schools provided an opportunity for reviewing and improving the educational system as a whole. (PGD)

Basic physical concepts of importance in understanding magnetic fluids (fine ferromagnetic particles suspended in a liquid) are discussed. They include home-made magnetic fluids, stable magnetic fluids, and particle surfactants. (DH)

Describes several ways to partially levitate permanent magnets. Computes field line geometries and oscillation frequencies. Provides several diagrams illustrating the mechanism of the oscillation. (YP)

Presents a rail gun demonstration that addresses a broad group of educational goals in introductory electricity and magnetism. Uses a battery-powered circuit consisting of a movable conductor placed across two conducting rails in a magnetic field to review mechanics, foster approximate reasoning and lateral class discussion, and demonstrate the…

The article presents inexpensive activities to teach elementary school students about electromagnets. Students learn to make an electromagnet with a battery, nail, and wire, then different activities help them explore the difference between permanent magnets and electromagnets. (SM)

This book is designed to provide guidance and ideas for science projects to help students learn more about science as they search for answers to specific problems. The 20 topics on electricity in this book suggest many possible problems to solve. Each topic has one detailed experiment followed by a section that provides additional questions about…

A classical Greek elementary magnet school in a large urban school district has identified the need for a multicultural fine arts program reflecting the contributions of ancient cultures to modern man. The author and teachers (K-5) of this school developed a multicultural program using classical literature, visual and performing arts, history, and…

Discusses when alternating and magnetic fields are independent. Provides examples of experiments involving mains hum and the detection of induced signals. Describes electric circuits and oscilloscope displays. (Author/YP)

Describes a fast and simple method for measuring the magnetic force acting on a current-carrying conductor using a digital balance. Discusses the influence of current intensity and wire length on the magnetic force on the conductor. (JRH)

The purpose of this research was to examine policies and curriculum practices in performing arts secondary schools in the United States. Data were obtained from a survey (including questionnaires, opinionnaires, interviews, and observations) conducted among 55 schools (total number existent in 1980) and visits to 11 selected institutions in the…
