Cities: Discover How They Work with 25 Projects
What does the word “city” make you think of? Traffic? Museums? Skyscrapers? People? Cities are thriving, vibrant communities that operate on several different levels—literally! Underground, on the ground, and way above ground, city dwellers are busy making their patch of earth as efficient, comfortable, and user-friendly as possible.
In Cities: Discover How They Work with 25 Projects, readers delve into all of the great things that make cities the wonderful places we love to both live in and visit. For instance, did you know that streetlights have been around for over 2,000 years? Benjamin Franklin was the first to light the dark streets of the United States. And how do cities handle all of the waste produced by the billions of residents? Wastewater treatment plants are where contaminants get removed before the cleaned water is flushed out to a lake, river, or ocean, or used for irrigation.
Cities are marvels of engineering and offer the perfect opportunity for students to flex those STEM muscles. Readers ages 9-12 are asked to figure out methods to provide water to the top floors of sky scrapers, keep cities safe during natural disasters such as earthquakes, and provide a steady supply of energy to inhabitants who live both near and far from power stations.
History, science, engineering, architecture, and technology combine in this fascinating book about a subject that billions of people will find familiar but only a handful—such as the kids who read Cities—will be able to explain.
