Show Me Science Chemistry & Physics - Magnetic Force At Work

The 9-title Wonders of Physics and Chemistry series covers everything from the definition of an atom to the science of light. Students can start to develop basic understandings of the fundamentals of science, then work their way up to more complex subjects. Each program includes a subject specific teachers guide which includes subject matter revision and suggestions on how to present material, questions to ask students, and class projects to help illustrate the key concepts. Magnetism is a force that causes like-charged objects to repel, and opposite-charged objects to attract. As such, it has always been a subject of fascination to scientists. As one of the fundamental universal forces, it exists in everything from asteroids to bacteria. This edition of Show Me Science describes what magnetic fields are and how they are created. The DVD also explains the Northern Lights and compares the Earth‰۪s magnetosphere to that of the sun.
