Really great explanations of things all kids are curious about. A little long for reading aloud but my four-year-old sat attentively through the whole book.

"How a City Works" by DJ Ward is an information non-fiction story about the inner workings of a city. The book explains things like power plants, sewage pipes, water treatment plants, and more so that a student can see all of the planning that goes into running a city. I thought this book was very informational and even taught me a few things like how a water treatment plant works. I would use this book in a Kindergarten classroom when we talk about community helpers as there are a lot of community helpers that contribute to the functioning of a city.

I read this as part of an engineering class that I am teaching. It is not specifically about engineering, but it does present a lot of opportunity to ask the question "how does that work". Which is a good question for engineers.
