Need for Industrialization• The War of 1812 showed the U.S. that it could not rely on imports for finished products.• The U.S. began to develop its own industries.• The Industrial Revolution was a period of rapid industrial growth in the early 1800’s.
Eli Whitney• Invented the concept of interchangeable parts.• Important product parts (like guns) were made exactly the same so individual parts could be changed as needed.• Made products cheaper
Mass Production• On an assembly line, a large number of goods are made at one time and all the same.• This made products cheaper than handmade items.
Importance of Change• Because they were cheaper to produce, products became affordable to more people.• The growth of this Factory System was found in the North.• North became more industrialized than the South.
Agricultural Inventions Cotton Gin• Invented by Eli Whitney.• Removed the cotton seed from the fiber. More cotton could be processed in a shorter period of time.
King Cotton• The Cotton Gin caused the demand for cotton to increase a great deal.• It also increased the demand for farmland and for slaves.
Agricultural Inventions Steel Plow• Invented by John Deere• Made planting seeds faster.
Agricultural Inventions Mechanical Reaper• Invented by Cyrus McCormick• His timesaving invention allowed farmers to more than double their crop size of wheat and grains.
Effects of the Industrial Revolution• More and more people moved to cities where there were factory jobs.• This was found more in the North than in the South which remained agricultural.• Products mass produced became more affordable.• As more money was made, machines were improved and new ones invented.
