Do you know how to get water to the top of a building? Or why potholes occur? If you’ve ever wondered how cities work, or enjoy real life applications of science, technology, engineering, and math, you’ll probably like this book. It explains why cities came about and how and why they work the way they do. Along the way, there are fun activities and experiments so you can get hands-on experience with things like building a skyscraper, making a battery, or simulating an earthquake to see what causes buildings to fall or stay standing.
I also liked learning about the history of cities, and seeing how we’ve made things better. For example, before flush toilets, you used to have to use a pot, which got dumped into the street and caused a lot of diseases; or how city planners work to help blind people know when to cross the street. Some signs make a loud beeping noise, like a chirping bird, when it’s time to cross. Others have a raised arrow you can feel with your fingers that vibrates and tells people when to cross and how much time they have. Pick up this book to learn even more interesting facts about cities, and try your hand at planning and building your own city!
