From the Publisher
"With simplistic text accompanied by vivid photographs, each title explains an area of physical science, such as force, motion, and density. Using real life examples, the author explains the topic in a meaningful way for young readers. Each title is organized into five sections, followed by a hands-on activity that demonstrates the book's subject. This series would be a welcome addition to school libraries' science section as well as elementary science classrooms. Recommended." --Library Media Connection
