Pulley

Pulley Synopsis

In Simple Machines: Pulley, young learners in grades 1-3 will explore what a pulley system is and why it is so useful. 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.
