Activity 12 answersPart D.Students should recognize that a glider with long, slender, curved wings is more efficient.Learning to Fly: The Wright Brothers’ Adventure82EG–2002–12–007–GRC
Activity 14 answersBelow are drawings of the gliders the Wright Brothers tested in 1900, 1901, 1902. Notice that Wilbur Wright isthe same size in all three, which means all three are drawn to the same scale.1. Try to list five ways in which all the gliders are alike.Answers will vary. Some possible answers could be that they all have two wings. They all have a pilot lying on thelower wing. They all have a small wing in front, etc.2. What are some of the ways that they are different?Answers will vary. Some possible answers could be that they are different sizes. They have different wingspans. Thesmall front wing is shaped differently, etc.3. The 1901 and the 1902 gliders both have about the same wing area and they weigh nearly the same. Whydo you think the 1902 is a better glider?The wings are longer and thinner. This gives the glider more lifting force and less drag.4. Notice that in all three gliders, Wilbur is lying down. What do you think the effect would be if he sat upwhile flying them?If he sat up he would cause more air resistance. This would slow the glider down.Activity 15 answers1. If you made $100 a month in 1900, and a camera cost $1, what percentage of your monthly salary would ittake to buy a camera in 1900?1 percent2. If your yearly salary today is $36,000 and you want to buy a camera that costs $100, what percentage ofyour monthly salary would you have to spend? How does this compare to 1900?Your monthly salary would be $3000. You would have to spend about 3.3 percent of your salary to buy a $100camera. The Brownie was much cheaper in 1900.3. The Wright Brothers had to buy all the food to stock their camp and ship it by boat and horse-drawnwagon. In 1900, a loaf of bread cost 5 cents. Today it costs about $1, or 100 cents. The price of breadhas increased by 100 cents divided by 5 cents, or 20 times. Find out how many times these items haveincreased in price since 1900 by completing the following table. You will need to find out today’s prices.Here are some examples:Food 1900 price Price today Increase5 pounds flour 13 cents $1.65 12.7 times1 pound butter 26 cents $2.50 9.6 times1 dozen eggs 21 cents $1.25 6 times1 gallon milk 27 cents $2.50 9.3 timesWhich item showed the biggest change in price?
