Discusses the principles of magnetic levitation presented in the physics classroom and applied to transportation systems. Topics discussed include three classroom demonstrations to illustrate magnetic levitation, the concept of eddy currents, lift and drag forces on a moving magnet, magnetic levitation vehicles, levitation with permanent magnets…

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)

Describes the construction and use of a magnetic needle that is stronger than those conventionally used for experiments with electromagnetism. (WRM)

Presents two quantitative Faraday's law experiments using a computer-assisted data-logging system. (Author/ASK)

This is the second book in a sequence of four volumes written and designed for parents of students of science, particularly for those at the lower and upper elementary and junior high or intermediate level, senior high students, college students preparing to teach science, and all those individuals who are interested in science and the application…

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)

This book is based on the premise that students apply thinking skills to learning science concepts by doing through firsthand experiences in an interactive, open atmosphere; constructing by building knowledge through guided inquiry; and connecting by relating learning to the world around them. The contents of this book have been designed to…

Designed to develop creativity in young learners, this book contains interdisciplinary activities which focus on the theme of electricity and magnetism. Activity pages are provided that can serve as front and back covers of a student booklet and the suggested activities can be duplicated for insertion between the covers resulting in a booklet for…

This book presents science activities designed for young children. The activities are divided into the following the content areas of chemistry, physics, earth explorations, weather watchers, flight and space, plants, animal adventures, and mathworks. Each activity features sections of language with science, required items, procedures, and…

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)

A partnership between a university and a science and technology magnet school brings a renowned herpetologist. Dr. Meg Stewart, to involve third-graders in her studies of coqui frogs. These students prepared to meet this scientist with a series of lesson plans (eight activities and four lab lessons) to learn the anatomy, behavior, and diversity of…

By playing with toys, children sometimes wonder how and why toys do what they do. At the moment of curiosity, interest can be captured and thinking can be influenced. This is a good time to focus on natural phenomena, provoke imagination, and promote scientific thinking. This book presents 53 classroom-tested activities to teach science with toys.…

Describes the implementation of a trajectory-plotting program for a microcomputer; shows how it may be used to demonstrate the focusing effect of a simple electrostatic lens. The computer program is listed and diagrams are included that show comparisons of trajectories of negative charges in the vicinity of positive charges. (TW)

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)
