Editorial Reviews

Children's Literature - Annie Laura Smith
Machines make work easier. Those which have many moving parts such as trains and cars are known as complicated machines, and those which have few moving parts are defined as simple machines. The latter include inclined planes, levers, pulleys, screws, wedges, and wheels and axles. The Contents page shows the scope of the information in the five chapters which address: Work, Machines, Friction, Parts of a Wheel and Axle, and Gears. The text and vivid photographs define the characteristics of wheels and axles like those used in bicycles, doorknobs, and screwdrivers. Sidebars on each photograph explain a related scientific concept while hands-on experiments show these concepts. A section titled "Learn More about Simple Machines" lists relevant books and websites. The Glossary defines machinery-related terms. An Index provides easy navigation through the text. This book is part of the six-book "Searchlight Series" which address how simple machines work. Other books include Put Inclined Planes to the Test, Put Levers to the Test, Put Pulleys to the Test, Put Screws to the Test, and Put Wedges to the Test. These books address the basic concepts of physics such as work, force, gravity, and friction, and will engage young readers, especially boys. Reviewer: Annie Laura Smith
Children's Literature
This entry in the "Early Bird Physics" textbook series explains what work is, defines the simple machine under discussion, introduces special terminology such as fulcrum, friction, or axle, and shows variations on that machine that make it more complicated. Simple hands-on activities explore some of the properties of wheels and axles and illustrate how screwdrivers, a form of this simple machine, can be configured to increase or decrease the force needed to turn them. A multiracial cast of children who look to be about nine or ten are photographed in posed situations to illustrate concepts, and most of them look realistic. Diagrams also help children see where force is applied or what can be altered to make work easier. An endnote to adults suggests helpful discussion questions and ways to explore the vocabulary specific to this machine while a bibliography of other books on the topic and two generic websites suggest further exploration. A glossary and index with a note on how to help children use these sources are added as well. All in all, the books in this series present solid support for adults in introducing simple machines to elementary age children. It is an appealing package children can also read for themselves. 2002, Lerner Publications, $23.93. Ages 7 to 10. Reviewer: Susan Hepler
School Library Journal
Gr 2-4-Written in simple language and sentences, these slim titles offer straightforward explanations of how things work. Starting with the basics, the material gradually builds upon readers' growing understanding of the concepts presented. The experiments suggested can be performed with little assistance and with materials found in the home. Clear, distinct, color photos of children demonstrating the activities on each page help reinforce the concepts, as do the many drawings and diagrams. Children will find these accessible titles informative, and may see their world in a different light after reading them. The narrow focus of each title may serve a purpose for classroom units.-Susan Shaver, Hemingford Public Schools, NE Copyright 2001 Cahners Business Information.

Many of the things that you do every day may not seem like work, but in fact they are. For example if you walk, have a snack, or race around in the gym you are actually working. When a scientist talks about the definition of work, "they don't mean the opposite of play," but rather use it to mean "using force to move an object." When you pull or push something you are using force. If you put newspapers in your recycle box you are performing work, but if you push against a building you are not because the building doesn't move. You have to move an object from one place to another in order to call it work. Riding a bike would qualify as work. There are machines that can make your work easier. We have both complicated machines or simple ones. Complicated machines "have many moving parts, while simple have few. Would you believe that wheels on your computer chair are simple machines? They are. Another thing you will explore in this book is friction, a force that makes a moving object slow down or stop." You will be able to experiment to find out how it works, learn how you can find it, and how you can lessen the effects of friction. If you take some of the same materials you used in the friction experiment (a spool and a straw), you'll learn about wheels and axles. You'll learn about different kids of wheels and axles, how and why the wheel travels a longer distance than the axle, which one takes more force to move by hand, you'll learn about gears, and you'll learn many other interesting things about wheels and axles at work. As you make your way through this book you will see other children work on experiments, experiments you too can conduct along with them. This is an interesting book with which young students can experiment and learn about simple machines. There are several scientific concepts and information about simple machines that lead up to the discussion on wheels and axles. These include discussions about work, simple and complicated machines, friction, how they are defined and what they do. Each concept is accompanied by an experiment that is clearly defined by photographs of young students as they work through it. The book is generously illustrated with numerous photographs and a diagram displaying how gears work. I like the layout of the book and can easily see the benefits of using it in a homeschool or classroom setting. This is one in the series, "How Do Simple Machines Work?" In the back of the book is an index, a glossary, and additional recommended book and website resources to explore. This book courtesy of the publisher.
