Gr 4–7—A well-done look at a less explored topic. Each volume begins with the history of the given waterworks, starting in ancient times in places as widespread as China, the Fertile Crescent, the Mediterranean, and the Americas. Developments up until the modern period are described, although most of the content generally focuses on those in the United States, sometimes to the detriment of the series. (For instance, the Three Gorges Dam project in China is not included in Dams.) The different types of scientists and engineers who work on each project are mentioned, as well as how STEM influences the siting, construction, and maintenance of various waterworks. Environmental concerns are also addressed.
