Essential Question What new technologies contributed to 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

What inventions paved the way? Other inventions that changed textile production…

Power Loom

Spinning Jenny

Water Frame

Steam Engine

Cotton Gin

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

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 HENRY BESSEMER

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

What was mass production? While machines were increasing the output of goods…

Two concepts would lead to the MASS PRODUCTION of goods

Making large amounts of the same product

Results in cheaper prices

What led to mass production? Those two concepts were:

INTERCHANGEABLE PARTS

and

DIVISON OF LABOR

How did the creation of parts change? INTERCHANGEABLE PARTS

Using machines to create parts that are exactly alike

Parts made by hand are never the same --- each part differs in some small way

The idea of interchangeable parts makes it easier to:  Fit parts together

 Fix parts when they break

How was labor made easier? DIVISON OF LABOR Instead of having each worker creating a product after product from start to finish…

Workers began to SPECIALIZE

doing one specific task

How did assembly lines work? This method is typically known as an ASSEMBLY LINE

HENRY FORD

used ASSEMBLY LINES in the early 1900s to build low-cost automobiles

What was the new power source? Throughout the late 1800s and 1900s, many discoveries kept industry moving

Some of the biggest discoveries involved electricity

What new inventions appeared? 1830 SAMUEL MORSE used electricity to invent the TELEGRAPH 1876 ALEXANDER GRAHAM BELL used electricity to invent the TELEPHONE

1896 GUGLIELMO MARCONI used electricity to invent the WIRELESS TELEGRAPH (radio)

How else was electric used? Electricity could be used for more than communication…

1879 THOMAS EDISON invented the electric LIGHT BULB

1882 The first central power station appears

Soon, electric generators will run factories and power machines
