Gr 4-7--These attractive books open with brief introductions to each culture and its technological background, followed by spreads that discuss how it developed or adopted technology that improved farming, architecture, transportation, communications, science and medicine, and more. The main text is limited to a few paragraphs per spread, supplemented with "Technical Specs" sidebars with facts about each topic. The images are the strongest element of the series, combining high-quality drawings (including exploded and explanatory diagrams) and photos of ancient sites and artifacts that illustrate how ancient technology worked. These books will help students understand the importance of interconnectivity among some of the cultures that adopted and adapted technology from their predecessors and neighbors. Solid choices.[Page 63]. (c) Copyright 2013. Library Journals LLC, a wholly owned subsidiary of Media Source, Inc. No redistribution permitted.
