Wedges

In this book, readers will learn about one of the six simple machines as described by Renaissance scientists. Vibrant, full-color photos and carefully leveled text will engage young readers as they learn how wedges increase force to either separate objects or hold things together. An activity provides step-by-step instructions for a specific, larger project, and a picture glossary reinforces new vocabulary. Children can learn more about wedges online using our safe search engine that provides relevant, age-appropriate websites. Wedges also features reading tips for teachers and parents, a table of contents, and an index. Wedges is part of Jump!'s Machines and Motion series.
