Uses extremely strong neodymium magnets to demonstrate several principles of physics including electromagnetic induction, Lenz's Law, domain theory, demagnetization, the Curie point, and magnetic flux lines. (MDH)

An exciting laboratory environment is activated by the preparation and novel use of magnetic materials to decontaminate water through adsorption and magnetic removal of metals and organics. This uncomplicated technique is also adaptable to the possible application of adsorbents to numerous other environmental substances.

This book provides a short course in the mysteries of seed structure, function, and development. Chapter 1, "Backgrounds, Hints, And Tips For Teachers And Parents," provides a basis for working with the mid-years student. Chapater 2, "Where Do I Start? What Do I Do?" provides procedural tips for science research. Chapter 3,…

Describes the construction and use of a simple apparatus to measure the magnetization density and magnetic susceptibility of ferromagnetic, paramagnetic, and the diamagnetic solids and liquids. (Author/GA)

Presents three examples of hands-on experiments that use an inexpensive magnetic-field sensor to quantitatively study magnetic fields. (WRM)

This book contains 25 experiments designed to help students understand some of the science used every day. Each experiment includes a list of materials, a series of easy-to-follow steps, an explanation of the scientific principle demonstrated, and additional scientific facts and information. No special or expensive materials are required.…

Describes apparatus for demonstrating magnetic lines of force, plastic discharge tubes, minimum angle of deviation of light passing through a prism, light scattering, and measuring high voltage. (SL)

Discusses the two-capacitor problem by considering the self-inductance of the circuit used and by determining how well the usual series RC circuit approximates the two-capacitor problem when realistic values of L, C, and R are chosen. (GA)

Explains how to use magnetic cylinders on an air table to demonstrate certain atomic structure and vibrational behavior in many face-centered metals like aluminum or copper. (GA)

Describes the discovery and characteristics of superconductors. Discusses some experiments on the levitation of a magnet over a superconductor. (YP)

We describe our experience in building a remote laboratory for teaching magnetic domains. Fulfilling the proposed on-line experiments, students can observe and study magnetization processes that are often difficult to explain with written material. It is proposed that networks of remotely accessible laboratories could be integrated in the Global…

This book contains hands-on science laboratory activities for grades 4 through 9 that use discrepant events to challenge students. All of the "puzzlers" are based upon science principles and include directions for building gadgets that explain the "puzzlers." Topics covered include: volume conservation, magnetic phenomena,…

This 12-chapter book examines different phenomena as viewed by those trained in physics. These views (or vistas) are promulgated to demonstrate that the infinite variety of things seen in the material world can be reduced to a handful of general laws and to share with the public the richness of the scientist's world view. The phenomena examined…

Designed for eleventh-grade students, this activity book contains nineteen electrical experiments. Experiments focus on topics such as commercial application of electromagnets, electromagnetic instruments, and commercial generators. Each experiment follows a typical format that includes the following parts: purpose, material used, procedure,…
