Introduces levers, explains how these simple machines work, and describes some common examples.

In Simple Machines: Lever, young learners in grades 1–3 will explore how levers give us the lift we need. From scissors to wheelbarrows, 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

A teeter-totter is more than fun to play on, it's also a lever, one of the six simple machines. This accessible book introduces readers to the lever through real-world examples. They'll learn about simple and more complex inventions using the lever that have changed the world. Detailed pictures with thorough annotations explain important engineering concepts. Cool "Technology in Action" spreads let readers get a close-up look at levers at work. This accessible text introduces readers to important STEM concepts and encourages an interest in engineering.

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

The shovel that helps you dig a hole, the chopsticks you use at lunch, and some of the big machines we see when passing by construction sites are all examples of levers. This book takes a look at the simple machine behind these different objects, using everyday examples and kid-friendly experiments to illustrate the physics behind this fascinating simple machine. Easy-to-read text will encourage readers, while large, colorful photographs will illustrate the concepts at hand. Students will be interested to see the ways that they interact with levers on a daily basis, and further reading and websites will encourage them to seek additional information.
