Read this book to find out!</p><p/><br></br><p><b> Review Quotes </b></p></br></br><br><p>The science and engineering behind the workings of each of the flying machines represented is described in clear, precise language within the developmental understanding of the intended grade levels. Readers learn about how each device gets into the air, stays there, is steered, and landed. A diagram of the equipment is a unique feature of each book. Large size font and sidebars make the text easily readable. Full-color illustrations are included, many full page. The authors make an effort to keep the photos and text gender neutral. Although formulaic in presentation, <strong> the series fills a hole in most elementary collections. Young boys eager for nonfiction books will grab these titles.</strong> --<em>Library Media Connection</em></p>-- "Journal" (8/1/2013 12:00:00 AM)<br><br><p>Though narrow of topic, <strong> these introductions combine plenty of big, bright color photos with explanatory texts that, for all their brevity, will give new readers healthy doses of specific information.</strong> Hang Gliders, for instance, offers not only a tally of the required gear but also covers techniques for steering, changing speeds, and landing safely. Both the narratives and images feature men and women in roughly equal numbers--and, even more laudably, Space Vehicles highlights a Russian Soyuz and its launch vehicle rather than now-obsolete American spacecraft, though the Hubble Space Telescope does make a cameo. Each volume ends with a labeled diagram, a page of 'Fun Facts, ' and a list of print and Web resources. --<em>School Library Journal</em>, Series Made Simple</p>-- "Journal" (4/1/2013 12:00:00 AM)<br>
