Electromagnetic Energy (cosmic rays, visible light, energy travels in waves through space and solid materials). Part of the Energy in Action series that goes beyond the basics, examining the five main forms of energy: mechanical, chemical, heat, electromagnetic and nuclear. This series is based on the concepts outlined in the National Science Education Standards for Physical Science: Properties & Changes of Properties of Matter, Motions & Forces and Transfer of Energy. Compelling examples show how stored energy is converted to active energy and how energy continually changes from one form to another. Grades 5-8
