Lesson 4 – Industrial Technology Essential Question What new technologies contributed the Industrial Revolution?

What effect did machines have? Machines, combined with new production ideas… revolutionized… changed … the lives of people around the globe

Where was the first change? It began with changes in the textile industry. JOHN KAY invented his FLYING SHUTTLE This sped up the weaving process

Other inventions that changed textile production… What inventions paved the way? Other inventions that changed textile production… Power Loom Spinning Jenny Water Frame Steam Engine Cotton Gin

The use of machines increased the demand for iron and coal. What other ideas emerged? The use of machines increased the demand for iron and coal. As the iron-making industry peaked, inventors worked on ways to turn iron into steel. This was called the Bessemer Converter!!!!

Blasting air through molten iron results in steel. Who was Henry Bessemer? BESSEMER PROCESS Blasting air through molten iron results in steel. This process lowered steel making costs from $200 a ton to $4 a ton. Now you could build ‘skyscrapers’!! HENRY BESSEMER

Steam engines relied on coal for power, not water Why was the steam engine important? Also, the invention of the STEAM ENGINE allowed factories to be built anywhere. Steam engines relied on coal for power, not water

How did transportation change? Industry still needed ways to transport raw materials to factories and goods to markets… STEAMBOATS RAILROADS These were simple combinations of combining steam power with new methods of iron and steel production.
