The document discusses several important inventions and developments during the American Industrial Revolution including oil discovery, alternating current, the light bulb, telegraph, telephone, railroads, and steel production. Edwin Drake's discovery of oil in Pennsylvania in 1858 provided a key energy source to fuel America's developing industry. Westinghouse improved on Edison's direct current with the invention of safer and more efficient alternating current, allowing electricity to be transmitted over long distances. Samuel Morse developed the telegraph in 1844, allowing the first widespread communication across the growing nation through electric wires. The transcontinental railroad connected the country and spurred further expansion. The Bessemer process for steel production was important as steel replaced iron and was a stronger, more versatile

6. Electricity Westinghouse discovered alternating current (A/C) which improved on Edison’s direct current. Why is this an improvement? What happens with A/C electricity?

7. Electricity New electronics are invented such as the light bulb and the electric chair. Can you predict others?

8. Communication Two very important inventions develop at this time. These two inventions create the first communication boom in U.S. History. The second gave us T.V. and Radio later in mid 1900’s the third gave us cell phones and the internet Name the two from this era.

9. Communication Telegraph Samual Morse: Developed Morse Code in 1844 and connected the country through electric wires. How did people communicate before this invention?

10. Communication Telephone

11. Communication The telephone was created by whom? How is the telephone from the 1800’s different from today?

12. Transportation - Railroads The Transcontinental Railroad is was of the most important moments in our developing nation. Why?

13. Transportation - Railroads

14. Transportation - Railroads A gold spike was used as the final spike driven into the ground during the connection of both parts of the railroad seen in the previous picture.
