TUESDAY- Reminder: Industrial test Friday- Reminder: Industrial key-terms due Friday –

do it right!

- Current events- Notes: “Inventions Change the Nation”

How do the revolutionary ideas of then affect us now?

- Activity: is an assembly line any better?...- Daily Reader

Inventions Change the Nation• Patents: Licenses for new inventions

• Telegraph (helps orders & cross-country communication) within the U.S. http://www.youtube.com/watch?v=kp3hY3r4yUg&feature=related

• Communication across the Atlantic are HUGE!

Samuel Morse invented this bad boy in the 1830s.

Using dots & dashes known as MORSE CODE, he could send electric signals over wires indicating words & letters of our alphabet

Cyrus Field – lays a cable under the ocean so telegraph messages can go back & forth b/w N. American & Europe

Inventions Change the Nation

- 1858 Queen Victoria sends first transatlantic message- Transatlantic: across the Atlantic message to President

James Buchanan in D.C.

Inventions Change the Nation

“In 5 months the cable had been manufactured, shipping

stretched across the Atlantic & was sending messages swift as

lightning from continent to continent”

Alexander Graham BellTelephone – 1867- Many thought it

was just a toy

- Tries to sell it to Western Union Telegraph Co. for $100,000

- They don’t want it (oops!)

- Bell ends up making millions

Alexander Graham Bell

Bell forms Bell Telephone Co : 1877»No longer need to go to

telegraph office» In-home communication» Businesses can find best deal

quickly»Orders can be placed quickly

Thomas Edison– 1876 – opens research lab in Menlo Park, NJ– Set the goal of inventing something new every 10 days• The Golden Approach – Edison’s approach of turning inventing

into a system– “Genius is 1% inspiration & 99% perspiration”

What do we remember about him???

Thomas EdisonElectric Power Plant• NY City 1882 - Wires business district first • Electric factories replace steam powered engines

• Safer, quieter, cleaner• Modern era of electricity begins

Technology Takes CommandRefrigerated Railroad Car• Refrigeration to the meatpacking industry

– Before: cattle, pigs, chickens raised/ sold locally (spoiled, couldn't ship far)

• Meatpacking plant in Chicago – (hub ½ way between cattle ranches in West & cities in the East)

• Cattle is shipped by train to Chicago• Slaughtered & carved up into sides of beef then loaded onto

refrigerated cars & carried to market

– Typewriter – speeds communication • Lightweight• Cheap• Easy to use

Technology Takes Command

!!!FUN FACT!!!Our keyboards

(then & now) are called “qwerty

keyboards”…WHY?.....

Less type-jams! It was so great we kept it!

First Flight– Orville & Wilbur Wright (bike mechanics)– 1903 – “Flying Machine” in Kitty Hawk, NC• 1908 U.S. military shows interest

– Flight over battlefields (bird’s eye view)– Gain enemy positions– 40mph plane WOAH

Automobiles

– Europeans had produced motorized vehicles in 1860s (France = leader & only rich Americans could afford cars)

– Ford 1913 – moving assembly line: method of production by which workers stay in one place as products travel past on a moving belt

•+ more jobs, less skill needed, better economy

• - if one person messed up, the whole process gets messed up

Automobiles

At first people thought cars were dangerous & scared horses• “No Horseless Carriages Allowed” signs• Tennessee: person planning to drive a car had to

advertise the fact a week ahead of time– BUT…prices dropped & people started buying them up–Men AND WOMEN can now drive!!!!….significance?

•Mass Production: making large quantities of a product quickly and cheaply–Allows Ford to sell his cars at a MUCH lower price than

other automakers–BUT…. Is an assembly line FASTER and BETTER?

Automobiles

Let’s Test it Out!!!!• I will put you into a group…• You will get a specific mission, depending on who

you are & what group you’re in• Check your group folder to see what your task is

ARE ASSEMBLY LINES MORE EFFICIENT?- You want to do your BEST at your task!- Poor work leads to UNEMPLOYMENT!

- You are selling a product based on QUALITY!- Keep your factory/ workplace NEAT & tidy!

Wrapping Up• You can start now…• FOR HOMEWORK DUE TOMORROW:– Write ONE PARAGRAPH ( 5 sentences) in Morse

code using your key on the back of your notes– It can be a note to a specific friend in class…– It can be a general note for anyone in class…– It can be song lyrics…– It can be a poem…– It can be ANYTHING (as long as it’s appropriate)
