PRODUCT SUMMARY

What do radios, microwave ovens and X-ray machines have in common? They all use different forms of electromagnetic energy to do work. In Electromagnetic Energy, learn that cosmic rays from space and visible light are also part of the family of energy waves known as the electromagnetic spectrum. Discover that electromagnetic energy travels in waves through space and can also move through solid materials. Fast-paced visuals and dynamic graphics help explain that the size of the waves determines their position in the spectrum as well as how much energy they contain. A fun demonstration illustrates that magnetic and electric forces are different aspects of electromagnetic energy, while a hands-on investigation proves that a light bulb radiates both visible light and infrared waves. Part of the multivolume Energy in Action Video Series. Includes a Teacher's Guide.

School Library Journal (July 2001)

Gr 5-8-This live-action series describes what energy is, how it is transferred and harnessed for use, and how it can be conserved. Sylvie, an aspiring scientist, narrates and acts in each video, as well as guides viewers through a variety of concepts. Electromagnetic Energy discusses how electromagnetic energy involves the forces of electricity and magnetism, as well as the movement of charged particles in the form of waves, thus creating different forms of electromagnetic energy. Energy: Potential and Kinetic introduces these concepts and the energy transfer between them. Energy Resources: Uses and Conservation focuses on various forms of energy and the importance of energy conservation. Heat & Chemical Energy explains how heat and chemical energy are interrelated; how heat energy is transferred through the processes of convection, conduction, and radiation; and how living things transfer, store, and release chemical energy through the processes of photosynthesis, digestion, and burning. Mechanical Energy shows how energy can be transferred from one object to another to make something move. Nuclear Energy discusses how the powerful energy within the nucleus of an atom can be released through the processes of fusion or fission. The research of Lise Meitner and Marie Curie are introduced, as well as the pros and cons of nuclear energy. The Transfer of Energy focuses on Einstein's Law of Conservation of Energy. In all of the videos, vocabulary words appear onscreen and are defined in context. There is a short review at the end of each video to reinforce main concepts. Repetition between videos highlights key concepts and ideas. Each program includes an experiment that students can replicate in the classroom. This series clearly explains a wide array of concepts associated with energy, and will strengthen middle school science collections.
