Read and find out about how cities work in this colorfully illustrated nonfiction picture book.

Millions of people live in cities around the world, but have you ever wondered how cities work? All those people need clean water to drink, a safe place to live, and a way to get all around the city. How do you take care of all those people’s needs? Read and find out all about the systems a city has to help keep everyone safe, healthy, and happy.

This book on city systems will appeal to the young civil engineer. How a City Works is filled with fun, accurate art, and includes tons of information. For example, it answers the question: Where does all the electricity needed to make a city run come from? How a City Works covers water treatment, power, sewage, recycling, and transportation.

How a City Works comes packed with visual aids like charts, sidebars, an infographic, and a funny, hands-on activity—how to clean up dirty “sewage” water, using puffed rice cereal, raisins, hot chocolate mix, and coffee filters.
