Editorial Reviews

Children's Literature
Using clear, everyday examples of screws, the author succinctly defines and explains the physics involved. A simple graphic design shows the parts of a screw. Readers can then see how screws are used to join, grip, lift, provide a tight hold and make things easier to turn. The final page provides an example of this simple machine as part of a snowblower, 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,
