Gr 7-10-These welcome additions present up-to-date information in an appealing format. Graham looks at the beginnings of the Internet as a communication tool for university scientists. Its uses in communication, medicine, education, and popular culture are examined along with the negatives of criminal activity, security issues, and violation of personal privacy. Morgan investigates different alternatives for the use of fossil fuels and outlines the pros and cons of biopower, wind, solar, geothermal, and nuclear energy. Continuing research and development and the economic implications of each alternative source are included. Bright, full-color photographs, charts, diagrams, and numerous sidebars enliven the presentations. The texts are clearly written in accessible language, except for the technical terms, making them ideal for students with below grade reading levels.-Elizabeth Stumpf, Clearfield Middle School, PA Copyright 2003 Cahners Business Information.
