PRODUCT SUMMARY
What is heat energy, where does it come from and how does it relate to chemical energy? Heat & Chemical Energy teaches students that heat energy comes from the motion of chemical atoms, and chemical energy is stored in the bonds that link atoms together. Discover how chemical reactions can give off heat energy and how heat can help release the stored chemical energy in fuel. Learn how heat travels through engaging demonstrations that illustrate the methods of conduction, convection and radiation. Students investigate how scientists measure calories -- the energy stored in food -- by constructing a calorimeter and burning a peanut. 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.
