Engineering: How the Six Simple Machines Support the World

Gr 7 Up–Readers will find a comprehensive look at simple machines in this addition to the “Inquire and Investigate” series. While the cover is not likely to attract attention, the contents are of good quality. Each simple machine is given its own chapter with an in-depth look at what it is, the physics of why it works, and how it has been used from ancient times to the present day. Additional attention is given to compound machines and how combining the simple machines can be even more powerful. The text is clear and accessible for Jr high and high school students. Each chapter includes side bars with extra information about the topic at hand, text boxes with short facts, and QR codes leading to related videos. All chapters are followed by step-by-step learning activities. Photographs and simple illustrations support the text throughout, and each chapter begins with a comic. The book is completed by a glossary, bibliography, and resources list.
