With the adoption of the Next Generation Science Standards, titles featuring age appropriate engineering concepts are needed in our school libraries.  Making Machines with Pulleys is solid example, including informational text interspersed with images and diagrams.  The three projects provide hands on opportunities that directly support the pulley concept discussed on the previous pages.  Each of the projects has a difficulty level, introduction, materials, clear step by step directions, and a “What did you find out?” concluding section.

Includes Table of Contents, Fun Facts, Glossary, Find Out More, and Index.
