Gr 3-6-These books have a logical, clear format. Those that discuss types of fuel feature chapters that explain what the source is and how it is formed, how it is harvested or harnessed, positive and negative aspects of its use, and future possibilitieswhether the problems with fossil fuels will be alleviated and whether nuclear waste can be disposed of, etc. Ollhoff does not suggest that any of these questions will be easily answered; rather, he proposes that scientists must continue to pursue the matter in an earnest fashion. "Future Energy" is the only title to discuss global warming at any length, but none of the controversies swirling around it are mentioned. It is also the only book that includes suggested activities for children to do at home. All of the books feature clear, crisp photographs; one depicts two children ill with cancer as a result of the Chernobyl disaster. Suitable for reports.
