Earlier in the year I spent a good few months learning all about cranks, levers, pulleys, axles and other simple machines and mechanisms. If you want to learn all about this stuff too then maybe you should check out How Machines Work , commissioned by Quarto books and published by Running Press Kids this October. How Machines Work is written by Nick Arnold, author of the best-selling Horrible Science series, and illustrated by myself. This book will not only tell you everything you need to know about machines but also give you a chance to build working models yourself.
Below is a small preview of the kind of thing you can find in the book.
