What Is A Wheel And Axle

Introduces the wheel and axle as a simple machine that can make it easier to move heavy objects, as well as to flatten dough.

Children will be thrilled to learn about the many uses of wheels and axles, from doorknobs to the insides of a clock. Inviting design and photos makes wheels and axles fun to learn about for young readers. Kids will love the fun with wheels section of this wonderful new book.

Rolling Along explores the benefits and uses of the wheel and axle. RobbO and RobbEE build a cart to make it easier to move a heavy load, and learn how the wheel and axle are also used for lifting and turning.

A wheel and axle is a disk and cylinder joined together. These two objects are only a simple machine when used in tandem. A wheel and axle is a modified first-class lever. When force is applied to the axle, the force is multiplied and transferred to the wheel. This causes the wheel to cover more area. Readers will learn about the invention of the wheel and axle, where wheels and axles can be found, and how they make difficult jobs easier.

We use wheels and axles several times every day. Young readers will learn how a wheel and axle work together, how they make work easier, and how they are used in larger, complex machines.

Every time you turn on a faucet, ride a bike, or open a door, you're using a simple machine called a wheel and axle. This book uses clear text and practical, every-day examples to explain the physics behind the wheel and axle. Easy-to-read diagrams and large, vivid photographs aid understanding, and experiments encourage students to learn first-hand how this helpful simple machine works.

In Simple Machines: Wheel and Axle, young learners in grades 1-3 will explore why the wheel and axle might just be the MVP of simple machines. This 24-page title uses real-world examples of simple machine mechanisms and explains how these feats of engineering can make daily work less difficult to complete. The Simple Machines series for grades 1-3 explains how basic mechanical devices, that are used for applying a force, can help make daily tasks much easier. Featuring before- and after-reading activities, a glossary, an index, and comprehension questions, this series helps young learners strengthen their reading comprehension skills while also introducing them to some of the most commonly used simple machines

Readers likely use the wheel and axle machine every day in the form of doorknobs and faucet handles, but this fascinating invention is often overlooked. This book helps readers understand how the wheel and axle simple machine is all around them and helps build compound machines. Approachable text provides lasting knowledge about the forces that make these devices work. Bright full-color photographs including a picture gallery showing familiar objects using this simple machine aid readers in comprehending just how these mechanisms make tasks easier. The concepts in this book enhance a variety of elementary STEM curricula.
