Editorial Reviews

Children's Literature - Joyce Rice
A simple machine is one that has only one moving part, or perhaps no moving parts. A rake that you can use to rake leaves is a simple lever and has no moving parts. Scissors are an example of a lever that has one moving part, which is the screw that holds the scissor blades together. Levers help us to do work with less effort. First, second, and third class levers are discussed. The reader will see that levers can be found everywhere. Before the discovery of levers, boats were difficult to move through the water. By adding a simple lever for a boat paddle, the boater could move his boat easier through the water. This series, titled "First Facts. Simple Machines to the Rescue," presents simple, brief explanations about how things work. Each title contains a hands-on activity that illustrates the principles discussed in the book or gives additional information. The glossary contains all the words that are in bold print throughout the text. An index and suggestions for further reading are included. This publisher maintains a web site, facthound.com, that directs children to resources chosen for age appropriateness. Each selection of resources is identified by typing in the book ID. Resources selected are then specific to age and the subject of the title. This management of resources is particularly helpful for this age group. All titles in this series have the same resource management page, and all titles are recommended for elementary classrooms and media collections.
