Future astronauts, pilots, would-be space scientists, and explorers will find plenty of activities here to feed their dreams. Every page gives kids a new chance to experiment, question, and think. They’ll learn about the basic laws of flight, and also about gravity and centripetal/centrifugal force. In addition, youngsters can get busy designing an airplane wing; constructing a simple helicopter-like toy; and making a variety of planes and gliders to see how they really work. Aerodynamics, astronomy, engineering, math, and art: this book has it all!
