4. Just for fun: Worst Invention Snuggies for Dogs It's bad enough that humans wear "the blanket with sleeves." Do we have to put them on dogs as well? Do we really?

5. THE INDUSTRIAL REVOLUTION (1790-1869) A change in the way goods are produced.

6. CAUSES  British ideas of a spinning mill and powerloom reach the United States.  War of 1812 prompts Americans to make their own goods.  New inventions! (ex.) Eli Whitney’s interchangeable parts)

7. EFFECTS  Factory system spreads  Young women and children from nearby farms work in mills.  Growing cities face problems of fire, sewage, garbage, and disease.  Industrialization increases at a rapid rate.  As country expanded, railroads were more widely used and more important to our nation’s economic growth.  New inventions made the production of goods easier.

8. Great Britain’s Industrial Revolution Great Britain’s Industrial Revolution British inventors created machines that transformed the textile (clothing) industry. British inventors created machines that transformed the textile (clothing) industry. British Parliament passed a law that forbade anyone to take these plans out of the country.

9. Stealing or borrowing? Samuel Slater heard of rewards being offered for these British ideas. In 1789, he left England and brought the ideas to the United States. Fearing he’d be caught, he memorized the plans for the mill.

10. 1.Samuel Slater- Textile Mill: easy way to mass produce clothing.

11. How were clothes made before the Industrial Revolution? 1- First, you had to turn the wool into yarn by carding, or combing, it. 2-Then, if you wanted the wool to have color you had to dip it in dye. 3- You could knit the wool yarn, but if you want to make cloth, the yarn must be fed into a loom for weaving. 4-Then the cloth had to be cut into a pattern and sewn into an article of clothing

12. New Inventions  Spinning Jenny: machine that could spin several threads at once Inventor: James Hargreaves

13.  Power Loom: using power of water, machine speeds of weaving of thread into cloth Inventor: Edmund Cartwright

18. New inventions 2. Eli Whitney: Interchangeable parts: identical, machine made parts for a tool or instrument (created by Eli Whitney). Not to toot my own horn or anything…but I also invented the Cotton Gin which revolutionized cotton production!

19. Until then, every rifle had been made by hand from stock to barrel; but the parts of one gun did not fit any other gun, nor did anyone expect them to. It was Whitney's idea to make all the parts of his rifles so nearly identical that the machines parts could be interchangeable from one gun to another. He did this by designing a rifle. For each part of the gun, a template was made. What are interchangeable parts?

20. A Little Problem People want to move West but travel was difficult. Settlers in the West needed ways to transport goods to eastern markets.

21. SOLUTION Americans develop new methods of transportation Better roads:Canals Steamboats, RailRoads National road Turnpikes

22. New Inventions in Transportation  1.Steamboat  2. ***Railroad  3. Canal
