A very basic introduction to screws, levers, planes and more.

These kids are playing a game, trying to move a person with a simple machine. Which will work better—an inclined plane or a lever? Readers will see them compare the simple machines to decide. This book supports engineering design standards for primary grades in the Next Generation Science Standards.

Building a fort in the backyard, a grandfather and granddaughter get help from six simple machines: lever, pulley, inclined plane, wheel and axle, screw, and wedge.

Create 3D printable models that can help students from kindergarten through grad school learn math, physics, botany, chemistry, engineering and more. This book shows parents and teachers how to use the models inside as starting points for 3D printable explorations. Students can start with these models and vary them for their own explorations. Unlike other sets of models that can just be scaled, these models have the science built-in to allow for more insight into the fundamental concepts. Each of the eight topics is designed to be customized by you to create a wide range of projects suitable for science fairs, extra credit, or classroom demonstrations. Science fair project suggestions and extensive "where to learn more" resources are included, too. You will add another dimension to your textbook understanding of science. What You'll Learn Create (and present the science behind) 3D printed models. Use a 3D printer to create those models as simply as possible. Discover new science insights from designing 3D models. Who This Book Is For Parents and teachers

Introduces six simple machines, describing how they work in more complex machinery and how they are used every day.

For use in schools and libraries only. Includes an assortment of activities using such simple machines as pulleys and levers.

Introduces simple machines, including screws, levers, wedges, and pulleys, describes how each makes everyday life easier, and provides activities demonstrating these machines in action.

In Todd McEwen's latest novel fine women are loved and lost, human error is not averted, and much is learned, of both a practical and a speculative nature.

Award-winning artist David Macaulay introduces readers to his hilarious new creations, Sloth and Sengi, in How Machines Work: Zoo Break! Get your cogs turning with these mega machines! This amazing, award-winning visual guide showcases the science and technology behind the most important machines ever invented. How Machines Work is a unique book full of inspiring illustrations by award-winning artist David Macaulay and packed with interactive elements, including press-out models, pop-ups, and pull-outs.
