The Wright Brothers decided to start their own experiments with flight.
Determined to develop their own successful design, Wilbur and Orville headed to
Kitty Hawk, North Carolina, known for its strong winds.
Wilbur and Orville set to work trying to figure out how to design wings
for flight. They observed that birds angled their wings for balance and control,
and tried to emulate this, developing a concept called “wing warping.” When they
added a moveable rudder, the Wright brothers found they had the magic
formula-on December 17, 1903, they succeeded in flying the
first free, controlled flight of a power-driven, heavier than air
plane. Orville flew their plane for 59 seconds, at 852 feet, an
extraordinary achievement.

Although the Wright machine had flown in Kitty Hawk, North Carolina on
December 17, 1903, it would not fly again; after the last flight, it was caught
by a gust of wind, rolled over, and damaged beyond easy repair.

Before the invention of the electric light bulb, people and businesses
used gaslights that were smoky and messy. Gas lights were also quite
dangerous and could start fires, which was a problem. Another problem
before the invention of the electric light was that factories and shops had to
close early because it would be too dark for any work to get done.
Thomas Edison had a solution to these problems; he decided to invent
the incandescent, electric light bulb. The electric light bulb was not
only safer than gas lamps, they also kept city streets lit up at
nights
which allowed for factories and shops to stay open later. The
invention of the light bulb led to increased productivity and longer
working hours.
Thomas Edison’s Light Bulb
Thomas Edison had to deal with many challenges in his “inventor” life.
For example:
• On December, 1914, Thomas Edison's plant (work building) caught fire.
• He had to rebuild
• He didn’t have formal education, but still worked hard to be a great
inventor
• He was partially deaf, but did not let that stop him
• Failed 10,000 times when making the light bulb, but did not give up

“Genius is one percent inspiration and ninety-nine percent perspiration.”
Alexander G. Bell was a
scientist and inventor. He
invented the telephone in 1876.
This invention made it
possible for people in large
buildings to speak to those on
other floors. It also made it
possible for people to speak to
friends and family that lived
miles away.
While trying to discover the secret to transmitting multiple messages on
a single wire, Bell heard the sound of a plucked string along some of the
electrical wire. One of Bell’s assistants, Thomas A. Watson was trying to
reactivate a telephone transmitter. After hearing the sound, Bell believed he
could send the sound of a human voice over the wire.
After receiving a patent on March 7, 1876, for transmitting sound along
a single wire, he successfully transmitted human speech on March 10th. Bell’s
telephone patent was one of the most valuable patents ever issued.
His invention helped increase productivity in factories by allowing
people to call workers on other floors.

George W. Carver was an
African American teacher at the
Tuskegee Institute.
He worked hard to improve
the lives of poor southern farmers,
by teaching them how to grow
crops such as peanuts, pecans, and
sweet potatoes instead of cotton.
By rotating the types of crops
grown each season, the soil would
remain nourished and crops would
grow better. This was called, crop
rotation.
Farmers had grown so many peanuts that they did not know what to
do with them. Carver invented over 300 products made from peanuts.
Peanut Cheese
Peanut Milk
Carver taught the farmers how to retain nutrients in the soil by using a crop
rotation, a system in which the cotton crop was alternated with other crops such as
soybeans, sweet potatoes, and peanuts. Carver’s crop rotation improved cotton yields
and gave farmers additional crops from which they could earn money. In addition,
Carver conducted numerous experiments on peanuts, soybeans, and pecans, finding
hundreds of practical uses for them including dyes, cosmetics, paints, plastics, and
even gasoline.
