Science Activities Science Activities I. Wright Brothers On December 17, 1903, Orville and Wilbur Wright successfully sustained the first heavier-than- air human flight. Unlike previous attempts at solving the “flying problem” that focused on developing more powerful engines, the brothers focused on creating a reliable method of pilot control (eventually known as three-axis control; patent 821,393). The brothers gained their mechanical skills by working for years with printing presses, motors, machinery, and bicycles. They also built a small homemade wind tunnel while working on the airplane which collected data more accurately than collected before. 1. Chronicling Flight in America Air travel had been a fantasy for humanity since the ancient world. However, by the 20th Century, it was becoming clear that sustained flight could actually become a reality. Examine, in Chronicling America, the public sentiment before (pre-December 1903) the Wright Brothers’ success by searching for an article about air travel (think “flying machine,” etc.). Where is your article from? What does the author think about flying? How is the inventor or idea portrayed? What was the predominant means of travel in 1903? Had man traveled through the air yet? Now examine the coverage of the Wright Brothers’ flight (search after Dec 17, 1903). Where is your article from? What does the author think about the flight? How is are the Wright Brothers and flying portrayed? How is the vocabulary different than how we describe flight today? Put yourself in the newspaper’s place. How might you cover the event differently? 2. Wright Brothers Collections The LOC has two collections pertaining to the Wright Brothers. The first is the Wilbur and Orville Wright Papers (http://www.loc.gov/collections/wilbur-and-orville-wright-papers), containing documents from the 1880s to the 1940s. The second is an exhibit on the “Century of Flight” (http://www.loc.gov/exhibits/treasures/wb-overview.html) that highlights many of the Wright Brothers achievements and their place in the larger narrative of humans taking to the sky. Most inventors and scientists do not act alone, locked in some dark room until the task is complete. In fact, collaboration and sharing resources/information is encouraged in the scientific community. The Wright Brothers also had some help from Octave Chanute, a French American railway engineer and fellow aviation pioneer. Providing them with advice and publicizing their endeavors, Chanute was well known in his time as the father of aviation. Read some of the correspondence between the Wright Brothers and Chanute (http://www.loc.gov/collections/wilbur-and-orville-wright-papers/?q=Octave+Chanute+Papers) What does the relationship between the Wright Brothers and Chanute seem to be? Friendly? Competitive? List three things that Chanute and the Wrights Brothers discuss in their correspondence and why it might be important. Today scientists can collaborate by sending emails and digital files almost instantly to each other. Video-conferences are an easy way to communicate as well, especially over long distances. However, in the 1900s, what ways were available for businessmen and scientists to communicate? How are those different than today? Keep in mind; Chanute lived near Chicago at that time and the Wright Brothers were in Ohio. Communication in 1900s Communication in 2010s 3.

Alexander Graham Bell 1. Chronicling the Telephone Invention Just like with the Wright Brothers, Alexander Graham Bell’s invention of the telephone occurs within the era covered by Chronicling America: 1876. Before the telephone, the telegraph had been the most immediate method for communicating with each other. However, that method still relied heavily on someone having to encode and decode messages for transmission and dissemination. Bell’s invention used a microphone and earphone to transmit electric signals across the wires. The first telephone call was made by Bell on March 10, 1876. Using Chronicling America, examine how the public reacted to the invention. List some of their comments and how they might be rewritten today: Comment Today’s Version What were some of the suggested uses of the new technology? Find an article in Chronicling America that describes how the telephone is changing lives. Is there another invention that has replaced the telephone in that example? Example of change Today’s equivalent How do newspapers cover inventions today? Did this invention get as much attention in the paper as the telephone? Use the diagram to think about how the style of reporting is similar and different than today: 1900s 2010s 2. The Creative Process Examine some of the notebooks from the Bell Collection (http://www.loc.gov/collection/alexander-graham-bell-papers/ ). Many scientists today still keep paper workbooks for lab work. How do you keep notes? What are the similarities and differences in your style versus Bell? Bell Yourself Scientists today use the “scientific method” when investigating. Looking at Bell’s notebooks, fill out the chart below for how you think he might have approached inventing the telephone. List evidence for each of your choices. Question Hypothesis Prediction Testing Analysis 3. Science Books Activity One of the little-known corners of the LOC site is the Science and Technology Reading Room (http://www.loc.gov/rr/scitech/). However, the Rare Book Reading Room (http://www.loc.gov/rr/rarebook/) also has science texts from previous centuries that do not usually show up in general searches. The Science, Magic, and Mathematics collection (http://www.loc.gov/rr/rarebook/digitalcoll/digitalcoll-magic.html) brings together texts showing our evolving understanding of the world around us. Why would magic and science books be grouped together in this collection? Some books talk about magic and witchcraft along with alchemy and “natural magic.” What do you think is the connection between these ideas? Some of the books, like the Explanation of Magnetic Atlas (http://memory.loc.gov/service/rbc/rbc0001/2006/2006frank31395/2006frank31395.pdf), have a list of subscribers at the beginning. Why do you think this is the case? The Explanation of Magnetic Atlas also has letters in the back from notable people like Thomas Jefferson. Why might this have been included in the book?

  • Preface: the Wright Myth
    P R E F A C E : T H E W R I G H T M Y T H t is hard to get flesh and bones on these two men. They come to us as stick figures in vests and white shirts, with their hard shoes Ihanging off the back of their flyers. They seem to not be of the earth and have few worldly desires after the desire to fly. Historians tramp from the Outer Banks to Dayton, Ohio, then to the Smithsonian in Washington or to the Ford Museum in Dearborn, Michigan, to see the Wrights’ bicycle shop. And after seeing the Wright Flyer in Washington or the markers in Kitty Hawk, they sit down to write the “Wright story.” It is a fact that the two men in the derbies have eluded historians and the rest of us for a long time. They were elusive men, after all, and so the questions linger behind the legend and the façade of the two Arrow collar young men who dazzled the world in 1903. History would have us believe that the Wright brothers were one in the same: Somehow, they both invented manned flight. They both had the same epiphanic moments while working on their gliders in Kitty Hawk. They both studied birds and deduced that wing warping was the key to controlled flight. They both worked out the complex aeronautical data that went into determining the amount of lift, the shape, the very design of a wing that would enable them to ascend to the heavens.

Launius National Aeronautics and Space Administration (NASA) Historian, Washington, DC Introduction In Stephen E. Ambrose's best-selling biography of Meriwether Lewis, Undaunted Courage, he makes the point that at the beginning of the 19th century everything moved at the speed of a horse. "No human being," he observed, "no manufactured item, no bushel of wheat, no side of beef (or any beef on the hoof, for that matter), no letter, no information, no idea, no order, or instruction of any kind moved faster.

  • Increasing Technology at the Turn of the 20Th Century Technological Explosion -In the Late 1800S and Early 1900S, the World Saw a Massive Increase in Technology
    Increasing Technology at the Turn of the 20th Century Technological Explosion -In the late 1800s and early 1900s, the world saw a massive increase in technology. -In 1876, Thomas Edison invented the light bulb. This completely changed the world and allowed businesses and factories to operate at night. -Edison, George Westinghouse, and others also pioneered the initial efforts of using electricity to power cities. This greatly increased industry. Thomas Edison’s invention of the light bulb radically changed the USA and the world. Steel and Skyscrapers -Henry Bessemer was able to inject air into molten iron to create steel in the mid 1800s. -This technique was used by Andrew Carnegie and others to mass produce steel. -Steel was then used to build massive skyscrapers in places like New York City and Chicago. Also, steel was used to create thousands of miles of train tracks in the USA. Through the Bessemer Process, factories were able to mass produce steel. The ability to mass produce steel led to the creation of skyscrapers, such as these in Chicago. Communication Technologies -By 1837, Samuel Morse had patented the telegraph and created Morse code. This system could send beeping sounds over long distances to be decoded. -This technology made it possible for instant communication to take place over great distances and even impacted the strategy of Lincoln in the Civil War. -By 1876, Alexander Graham Bell improved communication technologies by inventing the telephone. Now, people could talk over massive distances instantly. Through a system of timed beeps, an operator could interpret Morse Code by using a telegraph.

  • Orville Wright 1871-1948
    NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA BIOGRAPHICAL MEMOIRS VOLUME XXV ELEVENTH MEMOIR BIOGRAPHICAL MEMOIR OF ORVILLE WRIGHT 1871-1948 BY WILLIAM F. DURAND PRESENTED TO THE ACADEMY AT THE AUTUMN MEETING, 1948 ORVILLE WRIGHT 1871-1948 BY WILLIAM F. DURAND The boy is father to the man. Never, perhaps, has this old saying been better exemplified than in the life of Orville Wright. Born on August 19, 1871, in Dayton, Ohio, the son of Rev. Milton and Susan Catherine (Koerner) Wright, he began to show in early years the characteristics of mechanical genius and initiative which later, working with his brother, four years older, led to the successful demonstration of aerial flight in a man-made structure. Placed in kindergarten shortly after reaching five years of age, he began the systematic evasion of the school for associa- tion with another boy to play with an old sewing machine belonging to this boy's mother. Orville watched the clock and returned home at the hour he normally would from the school. This went on merrily until his mother, seeing his teacher one day, said that she hoped Orville was doing well. The teacher replied that she had not seen Orville since the first day when his mother brought him, and supposed that she had de- cided not to send him to the school. What transpired when the actual facts became known is not a matter of record. Orville was early inculcated with the lesson that if he de- sired spending money he must earn it and this he did in a great variety of ways.
