1. World History: Unit 3, Chapter 8, Section 1
Life in the Industrial Age :
Advances in Technology

2. Main Idea
The technological breakthroughs of the Industrial Age included advances in electric power, transportation, and communication.

3. Electric Power: Thomas Edison’s Lightbulb
1831-English chemist Michael Faraday discovered connection between magnetism and electricity leading to the first generator
1879-Edison developed first usable lightbulb
was the result of many hours of trial and error in his Menlo Park, New Jersey laboratory
made generators, light sockets, motors and other electrical devices
built first central electric power plant in New York City

4. Electric Power: Effects
Transformed industry in both U.S. and Europe in 3 important ways:
Factories no longer had to rely on steam engines to power machines
No longer had to depend on waterways to power the steam engines
Production increased with less reliance on sunlight
Question column- How did electric power affect industry and daily life?
In the home, electricity was cheaper and more convenient than candles, gaslights or oil lamps

5. Trains
efficient steam engines led to trains and steamships, while the internal combustion engine led to cars and airplanes
early 1800s, boats on canals and rivers carried heavy loads
1830: world’s first rail line connects Manchester and Liverpool
1840: U.S. had 3,000 miles of RR track in the east
Late 1850s: Bessemer Process improved steel making
1860: 30,000 miles of track linked major American cities, lowering the cost of goods
Question column-What advances in transportation occurred during the industrial age?

6. Steamships 1849: regular U.S. service began, west coast to east
1870: mechanical improvements changed ocean travel making it economically viable

7. The Automobile
1885: Carl Benz and Gottlieb Daimler developed a 3 wheeled vehicle
1908: Henry Ford began working on affordable cars using mass production to produce the Model T
a year later, a carburetor
1920: the Model T made up 40-50% of U.S. car production

8. The Airplane
December 17, 1903: Wilbur and Orville Wright flew 120 ft. at Kitty Hawk, North Carolina
the first powered flight in human history

9. Communication
The Telegraph: invented by Samuel Morse in with the aid of electricity; invented language known as Morse Code
The Telephone: invented by Alexander Graham Bell in 1876
The Radio and Phonograph: Radio invented by Italian Physicist Guglielmo Marconi in 1895; phonograph by Edison
Question column- What were the advances in communication, and how were they achieved?
first phone call- “Mr. Watson, come here I want to see you.”
