Cool gadgets and scientific discoveries don’t just come from laboratories. Many are dreamed up in the minds of storytellers.
I’ve had many parents come to me with a story that involves their child taking apart a family appliance/gadget because they were curious how it worked. This is the book for them. Five chapters feature the inner workings and history of fascinating devices. Chapter 1 focuses on inventions that came from science fiction. A four page spread discusses invisibility cloaks and how cloaking works. The idea is to make something disappear from your view. The trick is to bend light so it doesn’t bounce off an object and therefore you are unable to see it. There are three terrific diagrams that show how vision works and how it can be deceived. Other devices included in this chapter are inventions that hover, with a nice nod to Marty McFly, bionic arms and legs, and tractor beams. Can’t go wrong with Back to the Future and Star Wars. Chapter 2 is about household devices. Can you explain how a microwave works? I know about waves, but this explanation goes way deeper with more illustrations and photographs that would be excellent teaching resources on a document camera. Chapter 3 highlights items in a school. Topics include photocopiers, erasers, and thermoses. Hmmm. Maybe we could train students to fix photocopiers. If I had to guess which chapter in the book would be the most popular, I might go with Chapter 4 which is titled Extreme Fun. Who doesn’t want to know how surfing and roller coasters work? And bounce houses? Don’t get me started. How Things Work finishes with a chapter on transportation vehicles like rockets and escalators. Again, most of us have ridden an escalator but probably can’t explain how it works. Now you can know and impress your friends.
Inside each chapter is a biography of an inventor. Chapter 1 features David Moinina Sengeh. He designs prostheses and mentors other young innovators in Africa. I love that we have STEM role models in these pages. Another great section of each chapter is Try This! where readers get detailed instructions so they can create their own device. Chapter 5 gives details on how to make a submarine with a 2 liter bottle. I also appreciate how in tune the author is with what students want to know. These are the subjects that will get readers to the page every time.
