What do flagpoles and some window blinds have in common? They use pulleys to perform work! Pulleys are simple machines. They help us to do jobs more easily. But don't take our word for it. Put pulleys to the test with the fun experiments you'll find in this book. As part of the Searchlight Books™ collection, this series sheds light on a key science question?How Do Simple Machines Work? Hands-on experiments, interesting photos, and useful diagrams will help you find the answer!
"Because the working of simple machines is a common content area and the topic is well-developed, teachers will appreciate this series. In this book, the authors include hands-on activities that use everyday items, photographs of people using simple machines, and easy-to-read diagrams that explain how pulleys work. There are practical, everyday examples of simple machines throughout the book. The first chapter defines work by a scientist and provides examples of how simple machines are used to make work easier. Other chapters focus on gravity, friction, machines, and types of pulleys. The scientific content is clearly described in the text, and the description is enhanced by photographs of people using a variety of pulleys to do work. The content is written so that students in grades three to five can comprehend the science concept. This is a good book for a classroom or school library." --NSTA

"Put Levers to the Test, Put Pulleys to the Test, Put Inclined Planes to the Test and Put Wheels and Axels to the Test are part of a Searchlight Books series focused on simple machines. This book series emphasizes hands on investigations of simple machines in action. As their titles indicate, each book includes a section with detailed instructions and illustrations that allow young readers to safely investigate how simple machines work using inexpensive, readily available materials. Each book can stand on its own with an introduction to the physics of machines and work. Each book also includes full color illustrations on every page, a glossary and an index. The vocabulary and science concepts are appropriate for upper elementary school level students. However, with adult help, the books might also be used for even younger students." --Science Books & Films

"These books start with definitions of force, work, and machines, then explain how machines reduce the amount of force needed to do work. Interactivity is encouraged, as readers are directed to perform simple experiments along with children shown in accompanying pictures; the texts provide guidance on what to look for. Clear explanations, relatable examples, and effective visuals make these solid selections." --The Horn Book Guide

"This series includes lots of facts and examples of the concept of work, presenting the facts from the simple to the more complex. Large colorful pictures give the reader examples of work that a child could relate to, and a list of everyday household items that are needed to perform each example is included. Small boxes containing short facts about the pictures will grab the attention of younger and reluctant readers. Intermediate students will be able to recreate the examples given in each book in order to extend their understanding." --Library Media Connection

"The first two chapters in each title are nearly identical, although there are occasional changes in the photographs and the examples used to define the concepts work and machines. Subsequent chapters feature a specific simple machine and provide directions for basic experiments that children can accomplish, with the occasional exception, on their own, using easily located items. Final chapters explain that simple machines are everywhere. On the whole, the texts provide clear explanations and the experiments add a significant degree of interest. The color photographs are crisp and clear, as are the diagrams. Serviceable additions where the topics are a part of the curriculum." --School Library Journal, Series Made Simple
