1. Aim: How did the industrial revolution lead to new sources of power and advances in transportation and communication

2. The Steel Industry  In the mid 1850’s, Henry Bessemer invented the Bessemer process, a way to manufacture steel quickly and cheaply by blasting hot air through melted iron  *Steel is iron that has been made stronger by heat and the addition of other metals

3. Oil as a Power Source  Chemists invented a way to convert crude, or unprocessed, oil into a fuel called kerosene (cooking, heating, and lighting)This increased a demand for oil  Question: If the demand of something is high then what happens to the cost?

4. Edwin L. Drake  Proved that it was possible to pump crude oil from the ground.  Oil became a huge business in Ohio, Pennsylvania, and West Virginia

5. Electricity  Thomas Edison-in 1879, Edison and his team of inventors had created the electric lightbulb.  Q: What do you think was a major problem that Edison came across?

6. Answer  Few homes or businesses could get electricity.  He built a power plant that began supplying electricity to dozens of NYC buildings in 1882.

7. Advances in Communication  Telegraph Wires-connected the East and West coasts. (However, the telegraph carried only written messages

8. Alexander Graham Bell  1876-invented the telephone  Was a speech teacher who studied the science of sound  Between 1880 and 1900, the amount of telephones went up from 55,000 to 1.5 million

9. Automobiles and Planes  Henry Ford-introduced the Model T in 1908. He was the first to implement the moving assembly line in manufacturing, a process that greatly reduced the cost of building a product

10. Wright Brothers  Wilbur and Orville Wright built a lightweight airplane that used a small, gas powered engine  In Kitty Hawk, North Carolina, Orville Wright made the first flight in a gas powered plance

11. Individual Questions  1) What was the Bessemer process?  2) What is kerosene, and for what could it be used?  3) What problem did Thomas Edison face regarding the use of electricity, and how did he solve it?  4) Why do you think there were a rush of inventions in the late 1800’s?
