Flight

This solid introduction to flight begins by asking, “What do you know about being up in the air?” It then goes on to explain the science that makes it possible for hot-air balloons, birds, hang gliders, airplanes, and other air- and spacecraft to remain aloft. The many clear color photos and diagrams help elucidate the physics concepts, and an activity to make and test a paper helicopter allows readers to practice what they’ve learned. The simple design and large type are accessible and inviting. Final pages contain a glossary, reading list, Web site list, and an index.
