Discusses the meaning of velocity in the Lorentz force law and to what the velocity of the charge is relative. Provides a brief summary of the history of the magnetic force. (23 references) (MDH)

Describes a unit on magnetism that utilizes hands-on activities in which students make hypotheses for discrepant behavior, discover whether a magnet attracts one object through another, measure the strength of magnets, explore levitating paper clips, and play a game dependent on magnetic attraction. (MDH)

Presents a teacher-made instructional material that can be used to help students understand and retain the concepts of magnet and magnetic field. Doughnut-shaped magnets levitate above each other when placed over a post with like poles facing each other. Instructions are provided to make the device. (MDH)

Chemistry can be described on three levels: sensory, molecular, and symbolic. Proposes a particle approach to teaching chemistry that uses magnets to aid students construct molecular models and solve particle problems. Includes examples of Johnstone's model of chemistry phenomena, a problem worksheet, and a student concept mastery sheet. (MDH)

One of the basic principles of the Language Development Approach is that students must learn the language necessary to understand, talk, and write about all subject areas in order to succeed in school. This book contains information about teaching primary school science in the Northwest Territories with lessons that emphasize language. The goals…
