"In Mapping and Navigation: the history and science of finding your way, kids ages 9-12 will learn the history and science behind the evolution of mapmaking, and how much is still out there for discovery. Readers will explore ideas through hands-on-experiments while learning new terminology and interesting facts. Projects include using triangulation to measure distances, creating contour lines on a mini-mountain to understand elevation changes on a map, and inventing a sundial and compass to understand the basics of navigation. Whether mapping the solar system or mapping their own backyard, all readers will be able to understand mapping technologies and see the word in new and exciting ways."--Publisher's description.
