Слайд 10The First Telephone
On March 10, 1876, Bell shouted into his telephone
“Mr. Watson, come here, I want to see you.” His invention had worked!
Слайд 11Edison’s Light Bulb
Another inventor of the time was Thomas Edison.
A year
after Bell’s telephone, Edison invented the phonograph. A machine that could record a voice and play back it back.
Слайд 12Edison’s Light Bulb
Edison wanted to build a light bulb that was
safe and dependable.
At the time people used gas lights or candles.
He began working in his lab in Menlo Park, New Jersey
Edison relied on his investors to pay for the experiments.

Слайд 13Edison’s Light Bulb
An investor is someone who gives a business or
project money in hope of making a profit.
The hardest part of building the light bulb was finding the right materials.
Edison finally found carbon filament to work the best.

Слайд 14Edison’s Light Bulb
In 1879 Edison had a bulb that lasted for
two days.
An inventor Lewis Latimer improved the light bulb by developing carbon filaments that lasted longer.

Слайд 27The Wright Brothers
In 1899 they built a glider to test.
They went
to Kitty Hawk, North Carolina because of the strong winds and it was not near any big towns.
They had many failures but kept trying.
Finally, on December 17, 1903 the Flyer took flight for 12 seconds and flying 120 feet.

Слайд 28Inventions and Industry
People started businesses to offer telephone and electric service.
Companies
began making streetcars, automobiles and airplanes.
This was good news for Blanche Stuart Scott. She drove a car across the country to help advertise for the company.
