Liquids and Gases: Principles of Fluid Mechanics (Secrets of the Universe)
Grade 6 Up-Adapted from the author's Secrets of the Universe:  Discovering the Universal Laws of Science (Atheneum, 1987;  o.p.), these titles each provide a brief introduction to the  laws and principles governing a specific area of science. The  clean layout and concise coverage include activities for further  study, although they would not be appropriate for science-fair  projects. The texts are almost identical to the corresponding  chapters in the original, but they are supplemented here with  clear, two-color line drawings and diagrams. In Liquids, the  chapters focus on Archimedes's principle, Pascal's law, Boyle's  and Charles's laws, and Bernoulli's principle, although other  scientists are covered. Waves covers optics, the laws of  electromagnetism, and electric current (Ohm's law and Joule's  law). Libraries that already own Secrets of the Universe may  want to skip these titles, but many will feel that they merit  consideration because of their appealing format and focused  subject areas.Maren Ostergard, Bellevue Regional Library, WACopyright 2001 Reed Business Information, Inc.
