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)

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…

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)

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…

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)

This guide is designed to provide teachers (grade 2) with a ready resource for planning, organizing, and teaching science to the elementary child. Many suggested activities will provide an enriched science program. Each unit lists estimated time, content, concepts or "understandings," problems to deal with, activities, suggestions for…

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)

Intended for regular classroom teachers in intermediate science classes serving the gifted and talented student, the curriculum handbook is designed to give a basic understanding of gifted education, to list appropriate goals and objectives for the gifted student, and to suggest materials and strategies for implementation within the regular…

This study was designed to determine whether fifth and sixth grade children retain both the factual materials and applications of the factual materials better when a unit in electricity and magnetism is taught by the inductive method or when the unit is taught by the lecture-demonstration technique. The sample consisted of 346 pupils of fifth and…

Presented are three computer projects: vector analysis, electric field intensities at various distances, and the Biot-Savart law. Programing suggestions and project results are provided. One month is suggested for each project. (MVL)

Describes a kit designed as a leisure time activity for teenagers and adults who have had little previous experience of magnetism and electricity. The kit may be useful for homework, small group work, or as a training course for nonscientist science teachers. (PR)

This resource book introduces first-grade children to the world of magnetism and magnetic effects. The students are provided the opportunity to observe interactions between magnets, identify what materials a magnet will and will not attract, study magnetic fields, induce temporary magnetism, make an electromagnet, and use compasses. The 16 lessons…
