  • 3. The Industrial Revolution
    • The changes are continuing from the US economy prior to the Civil War.
    • The main change was from an economy based on agriculture and trade to production of manufactured goods.
  • 4. Manufactured Goods
    • Required the following to make goods:
      • Raw materials (land)
      • Workers (labor)
      • Capital equipment (capital)
      • New ideas (technology)
    • Technology = new ideas about how to do something as well as the equipment needed to do it.
  • 5. Transportation System
    • The transcontinental railroad shipped materials to cities where manufacturers changed raw materials to consumer products.
    • Then, it was shipped all over the country!
      • Examples:
        • Grains from Great Plains became cereal
        • Hogs and cattle became meat served for dinner
        • Iron ore was shipped to build more railroads and skyscrapers.
  • 6. New methods of Mass Production
    • Used to turn raw materials into consumer products.
    • Andrew Carnegie:
      • Bessemer Process- converted iron to steel
      • His company Carnegie Steel built huge steel foundries and created a monopoly on the production of steel.
  • 7. New methods continued
    • Meat Packers-
      • ‘ dis-assembly’ line where hogs and cattle were killed and then cut into steaks and chops, and leftovers were made into sausages.
      • Some said they could use every part of the pig, but its squeal
    • Interchangeable parts-
      • Used first in the 1700s by Eli Whitney
    • Assembly line-
      • Henry Ford used in 1913 to make automobiles
  • 8. Telegraph vs. Telephone
    • Invented by Alexander Graham Bell to improve communication of the telegraph.
    • Businesses could communicate more quickly and easily.
    • Soon homes of wealthy people had phones and eventually almost every home would have one.

  • 9. The Light Bulb
    • It was NOT invented by Thomas Edison, instead he improved it and made it practical for use!
    • Edison invented the incandescent light bulb in 1879.
      • Promoted economic growth because it made it possible to light factories and homes more safely.
      • Made use of electricity popular.
  • 10. Electricity
    • Electric generator was built in 1881 and electric lines were strung in cities and towns.
    • Electricity helped manufacturing plants, so they no longer had to use water power or steam power from coal burning.
    • Light bulb contributed to economic growth by encouraging development of electrical powered plants.
  • 11. More about electricity
    • Electricity helped:
      • Transportation by electric powered street cars
      • Labor saving devices:
        • Washing machine and vacuum cleaner
        • Only some women could afford them
      • Job opportunities:
        • Telephone operator
        • Sewing machine
        • Typewriter
  • 12. Closure
    • Exit Slip:
      • Write 5 facts you learned today during the lesson on new inventions and technologies .
    • Share at your learning club 1 thing you thought was the most interesting!
