• You and your group collectively will brainstorm why this
invention is so important to you.
• Come up with 5 reasons why this invention is something you
can not live without.
• Choose 5 people out of your group to present one idea each.

2. WELCOME
TO
INDUSTRIAL REVOLUTION
“INVENTIONS”

3. INVENTIONS
 Let’s look at some of the inventions & explain how those
inventions made your “most important” inventions possible
 Steam Engine
 Textile Industry/Factories
 Steam Turbine/electricity
 Phonograph/Music
 Telegraph/Global Communication

4. BEFORE MACHINES
Before 1800
wind, water and
the strength
from people and
animals worked
machines

5. STEAM ENGINE
James Watt “re-invented” the first
steam engine
Why was the steam engine so
important?
 The coal mines in Great Britain were
shallow. This creates a problem for
mining.
 When it rained (and it rained a lot), the
coal mines would flood.
 The steam engine would pump the
water out of the mines creating
compressed steam. This steam made
the pump work harder and faster
 This process and invention set the
stage for the Industrial Revolution. It
would change EVERYTHING.

6. STEAM ENGINE
Before the Steam Engine After the Steam Engine
 Before the steam engine, all
machines were worked by
hand.
 Production of goods cost more
because production was labor
intensive. Everything was
made by hand
 The only way to travel was by
horse and carriage
 Many people only had one set
of clothing per season. *Unless
 Now machines are powered by
steam
 Machines are able to produce
more goods at one time = Mass
production
 Steam Engine influenced the
Steam Boat, Steam Locomotive,
and Automobiles
 People could now afford
clothing, canned food, etc.
thanks to cheaper production

7. FIRST MAJOR INDUSTRY TO FORM:
TEXTILE
WHY?
 Before textiles, all cloth was made by hand. Handmade
goods are labor intensive and take a long time to make. This
is not cost effective.
 Solution: Steam powered machines were made to create
cloth and other goods at MASS PRODUCTION. When
created in masses, goods are cheaper to make therefore
cheaper for the consumer to buy.
 Mass productions + Cheaper product to consumer = Profit
 The Steam Engine made Textile’s possible.

8. TEXTILE FACTORY WORKERS
IN ENGLAND
1813 2400 looms (cloth
weaving machines)
150,000 workers
1833 85,000 looms 200,000 workers
1850 224,000 looms >1 million workers

9. Tell me what you see in this picture
What things do you see that would tell you this was during the Industrial
Revolution

10. Mass Production
• Mass production began in U.S.
• Elements:
– Interchangeable parts
– Assembly line
• Production and repair faster and
more efficient
Effects
• Dramatic increase in production
• Businesses charged less
• Affordable goods
• More repetitious jobs
• Soon became norm
FACTORIES AND MASS
PRODUCTION

11. HERE ARE A FEW
OF
THE TEXTILE INVENTIONS

12. Cotton Gin: 1793
Invented by Eli Whitney
to mechanize the cleaning
of cotton
A machine that quickly
and easily separates the
cotton fibers from the
seeds, a job previously
done by hand
Led to the demand for
more slaves

13. COTTON GIN
 What was going on in the world during this time period
related to cotton?
 Why do you think this invention was so important?
 How did it lead to the demand of more slavery?

14. Spinning Jenny: 1764
Invented by James Hargreaves
At the time, cotton production
could not keep up with demand
This machine spun many
threads at the same time, thus
reducing the amount of work
needed to produce yarn
increased productivity =
produced yarn quickly= profit

15. (Henry) Bessemer Process for the
Manufacture of Steel: 1856
Bessemer process involved using oxygen in air blown through
molten pig iron to burn off the impurities and thus create steel
Lowered the cost of steel production, leading to steel being
widely substituted for cast iron
Steel used for the production of guns and railway structures such
as bridges and tracks
This changes the way we fight wars, transport goods and
travel. This is HUGE

16. HOW THE BESSEMER PROCESS
WORKED

17. WHAT CAME OUT OF THE BESSEMER
PROCESS
 Millionaires (Charles Schwab) and
Billionaires (Andrew Carnegie)
 Mass Production of Steel
 Railroad Tracks – changed
transportation
 Bridges – changed travel
 Steel to make Skyscrapers – Changed
our landscape
 Guns – changed warfare
Imagine our Country without this

18. LET’S REVIEW WHY THESE INVENTIONS
ARE IMPORTANT
BY
ANSWERING THESE QUESTIONS:

19. ESSENTIAL QUESTIONS
 Why do you feel these global changing inventions
happened all at one time?
 Which invention thus far do you feel has had the most
impact on our world?
 How have the inventions mentioned thus far changed
our world (both positively and negatively)?

20. STEAM TURBINE = ELECTRICITY
Charles Parson patents the
Steam Turbine in 1884
 Parson realized the need for
a rotating machine to convert
the power of steam directly
into electricity
 After inventing the Steam
Turbine he took his
knowledge and invented the
Turbinia (a 100-foot long ship
that was powered with a
steam turbine

21. DOES THIS LOOK FAMILIAR?
Today nearly all of the world’s power that is
supplied to a major grid is produced by turbines

22. PHONOGRAPH
Thomas Edison patented the
phonograph in 1878
 Edison was working on 2 other
inventions (telegraph and
telephone) when he invented the
phonograph.
 The phonograph is a machine
that would use sound vibrations
to make indentions onto a
cylinder by the recording needle.
 This machine was able to record
not only music but also
speeches. This would become
important during WWI

23. Check out
Edison’s ad for
the phonograph

24. QUESTIONS ABOUT THE AD:
 Who do you think placed the ad?
 Who is the intended audience?
 What is the name of the company?
 Where is the company based out of?
 What words do the advertisers use to make YOU want
to buy this machine?
 Do you feel $20 for the phonograph is a fair price?
 Why?

25. WE HAVE COME A LONG WAY

26. TELEGRAPH
Samuel Morse invented the
Telegraph between 1830’s-
1840’s
 Revolutionized long-distance
communication.
 Worked by transmitting
electrical signals over a wire
laid between stations.
 Laid the groundwork for the
telephone, fax machine, and
internet.
 Connected people globally!

27. HAVE YOU EVER HEARD OF MORSE
CODE?
 In order to transmit
messages, Morse had to come up
with a code system. Each letter of
the alphabet was assigned a code.
 Once the telegraph operator
received the code, they would
translate into English.
 The U.S. government hired Morse
to conduct special military
operations using the Morse Code.
 Morses’ first telegraph message
was sent from D.C. to Maryland. It
said, “What hath God wrought.”

28. LOOK FAMILIAR? Try this out at home
