Editorial Reviews

School Library Journal
Gr 3-5-Here is a clever way of combining some science and social studies in the curriculum. The title is not misleading, but there is far more to this book than one would initially suspect. The author leads readers through the construction of a castle, the workings of the drawbridge, the execution of a siege and how the inhabitants would protect the castle from attack, methods the invaders might use, and what would happen afterward to repair the damage. While readers are drawn into the action, they are also introduced to the simple machines used during this period of time. The stonemason's wedge, the inclined plane of the castle road, the levers used in the drawbridge, the screw of the crossbow, the axles in the moving siege towers, the fulcrum in the catapult-these and many other terms are interspersed throughout the text. Detailed, easily interpreted diagrams are included for added understanding of concepts. Vivid and realistic photos add to the appeal. An excellent choice for research or for general interest.-Corrina Austin, Locke's Public School, St. Thomas, Ontario, Canada Copyright 2006 Reed Business Information.
