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)

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)

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)

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)

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)

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…

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)

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…

Describes making a magnetic pendulum similar to those seen in novelty shops. Presents an open-ended activity and a more structured activity using this pendulum. (PR)

Proposes the use of metal cans to create science experiments that motivate students to investigate the scientific concepts of electricity, magnetism, heat, inertia, and sound transmission. Describes several experiments using cans in which students explore the properties of metal. (MDH)

Discusses three broad classes of magnetic behavior: diamagnetic, paramagnetic, and ferromagnetic. Presents a simple lecture demonstration using an overhead projector to synthesize triiron tetraoxide and to show its interaction with a magnetic field and comparing it to a paramagnetic material. (MVL)

Six thematic activity booklets are presented for implementing Project EAGLE, an enrichment program for gifted and talented primary-level children. "Animals 3" introduces endangered animals and locates their home areas on maps or globes, using nine learning activities involving science and creative writing. "Magnets" discusses…

Presents instructions and schematic diagrams for an activity that allows students to discover the relationship between electricity and magnetism. Students draw conclusions and form hypotheses regarding their observations. Suggestions for further study are provided for "real world" experiences by students. (ZWH)

The significant stages in the development of understanding of the concept of electric charge are discussed. The history is outlined with references to certain important experiments, and suggestions are made for relevant school demonstrations and experiments. (KR)
