2 B. Fill in the Blanks: 1. n the ancient reek story, carus ignored his father s warning and flew too close to the sun. e fell into the sea and drowned. (p. 7) 2. he unfortunate experiment by a man in Spain trying to fly from a tower might be described as an early attempt at a jump by parachute. (p. 7) 3. ites were among the first man-made devices to take flight. (p. 7) 4. he hinese used their rockets mostly for celebrations, but also in battle to scare off the enemy. (p. 8) 5. he ancient hinese legend of a man who tried to ride his rockets to the moon says he went up in a ball of fire and perhaps became the Man in the Moon. (p. 8) 6. a Vinci s drawing of an airscrew looks a lot like a modern helicopter. (p. 9) 7. ike other scientists, eonardo da Vinci observed the world closely. lso like other scientists, he kept good records. (p. 9) 8. liders were the first aircraft that had directional control. (p. 10) 9. a Vinci was fascinated with birds, and he experimented with flapping-wing machines. (p. 10) 10. Birds are very powerful for their size. heir large wing muscles and hollow bones make them well suited to flight. (p. 10) 2

6 . rue/false: Put a in the blank if the sentence is true and an F if it is false. F 1. Wilbur Wright made the first controlled, sustained, and powered heavier-thanair flight. (p. 6) F 2. he hinese invented kites around 1000 B but they were too small and flimsy to be of much practical use except as toys. (p. 7) 3. egend credits a hinese named Wan oo with an attempt to fly to the moon, using 47 rockets fastened to a chair. (p. 8) F 4. he hinese designed the first known helicopter. (p. 9) F 5. he publication of eonardo s notebooks advanced aviation during the enaissance. (p. 9) 6. Birds are able to fly in part because they are very powerful for their size. (p. 10) 7. bird s flight is similar to an airplane s in some ways but different in others. (p. 11) 8. he phenomenon known as Bernoullian lift helps aircraft wings move upward. (p. 12) F 9. Sir saac ewton formulated his three laws of motion producing the first designs for a helicopter. (p. 12) 10. nly when people stopped trying to fly as birds do did the way open for the Wright brothers success on the orth arolina dunes. (p. 13) 6
