A new series, focusing on the most basic engineering foundations, Simple Machines covers all six simple machines in straightforward, easy-to-read text. Each book has a similar format—first covering the definition of the machine, how it works, examples, and how the machine works within complex machines. Using consistent vocabulary, key terms recur in each volume. Large, bright, contemporary photographs of children using each machine or the machines themselves are clearly labeled for easy identification of parts and purpose. Sprinkled with short, fun, often historical facts, the book takes a straightforward subject and connects it to everyday life. An excellent tool to reinforce standard science curriculum, the series is also a terrific resource for teaching expository reading comprehension to beginning readers. Further information on the machines is available through the factsurfer.com website. Bibliography. Glossary. Table of Contents. Index. Recommended.
