How Do Helicopters Work? (How Flight Works)

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, the series fills a hole in most elementary collections. Young boys eager for nonfiction books will grab these titles. —Library Media Connection
