This activity book tells the amazing true story of how two bicycle-making brothers from Ohio, with no more than high-school educations, accomplished a feat that forever changed the world. At a time when most people still hadn't ridden in an automobile, Wilbur and Orville Wright built the first powered, heavier-than-air flying machine. Woven throughout the heart-warming story of the two brothers are activities that highlight their ingenuity and problem-solving abilities as they overcame many obstacles to achieve controlled flight. The four forces of flight -- lift, thrust, gravity, and drag -- and how the Wright brothers mastered them are explained in clear, simple text. Activities include making a Chinese flying top, building a kite, bird watching, and designing a paper glider, and culminate with an activity in which readers build a rubber-band-powered flyer. Included are photographs just released from the Wright brothers' personal collection, along with diagrams and illustrations. The history of human flight and its pioneers, a time line, and a complete resource section for students are also provided.
