Editorial Reviews

Children's Literature
Using clear, everyday examples of wedges, the author succinctly defines and explains the physics involved. A simple graphic design shows the components of a wedge. Readers can then see how wedges are used to cut, split, push apart, and push together, to hold tight and to grip. The final page provides an example of this simple machine as part of a complex machine. An experiment using common and inexpensive items provides the student with a hands-on way to understand the concept. Words to know, Internet sites, a brief bibliography and an index are included. This is one of six books in the high quality "Understanding Simple Machines" series, which is part of "The Bridgestone Science Library." 2001, Bridgestone Books/Capstone Press,

Gr 3-4-These series titles are quite similar to entries in Michael Dahl's "Early Reader Science" series (Bridgestone). Welsbacher's texts are slightly more difficult to read, but follow the same pattern. The most noticeable difference from the earlier titles is the inclusion of a brief list of Internet sites and attention to diversity in the brightly colored photos that appear on every other page. Also, some terms, apparently chosen at random, are defined in the lower right-hand corner of the page instead of in the glossary. If you already own Dahl's books or other series titles on simple machines, you most likely won't need this slightly updated visit.-Patricia Manning, formerly at Eastchester Public Library, NY Copyright 2000 Cahners Business Information.
