To a child, a city is a chaotic, vibrant community whose workings can seem quite mysterious. How were subways built? How does water get to the top of a skyscraper? Is there any organization to a bustling metropolis? Cities: Discover How They Work will give kids a view into the inner functioning of these urban areas. They’ll learn about all the parts that come together to make cities work and how they’ve grown and changed since the very first riverside settlements.

Fascinating sidebars, unique illustrations, Words to Know, and fun Did You Know facts combine with age-appropriate hands-on activities to make learning fun and reinforce learning. Projects include creating subway cut-aways to understand how transportation systems work, building an aqueduct to learn how cities get water, and experimenting with skyscraper design. This STEAM title, which integrates science, technology, engineering, art, and math includes a glossary, list of resources, and index.
