He also thought for a long time: Why does the sun always rise slowly from the east in the morning and hide behind the mountains in the west in the evening? Why are there white clouds floating in the blue sky...
When he was 5 years old, one day, Edison suddenly disappeared. Dad looked around anxiously, and finally found him squatting in the chicken coop!
"What are you doing here?" Dad asked strangely.
"I'm hatching chicks." Edison answered seriously. It turned out that the day before, he saw a hen lying on an egg and hatched a chick, so he wanted to try it himself to see if he could hatch a chick.
Dad pulled him up angrily and funny, and said to him: "Silly boy! You can't hatch chicks! Let's go!"
Little Edison wrinkled He frowned and asked dissatisfied: "Why can't I hatch chicks, but a hen can?"
Edison was such a curious child. He wanted to know everything and wanted to try everything himself. try.

C. Celebrity Story 200 Words Edison
One snowy night, Edison’s mother suddenly fell ill, and his father hurriedly called for a doctor. The doctor said: "Your mother has acute appendicitis and needs surgery." At that time, there were only oil lamps and no electric lamps. The light of the oil lamp was very dim, and you would accidentally perform the wrong surgery. Edison suddenly thought of a good idea. He took out all the oil lamps in the house and put a mirror behind the oil lamps, so that the doctor could complete the operation smoothly. The doctor said: "My child, you saved your mother with your wisdom and cleverness." Edison took his mother's hand and said: "Mom, I want to make a sun at night."
In 1868, Edison Came to Boston as a telegraph operator. In the same year, he received his first invention patent. This is a device that automatically records votes. Edison thought the device would speed up the work of Congress and that it would be welcomed. However, one MP told him that they had no intention of speeding up the agenda and that sometimes voting slowly was politically necessary. From then on, Edison decided not to make any inventions that people didn't need.
In early June 1869, he came to New York to look for work. While he was waiting to be summoned at a broker's office, a telegraph machine broke down. Edison was the only one there who could fix the telegraph, and he got a better job than he expected. In October, he and Pope jointly established a "Pop-Edison Company" to specialize in scientific instruments for electrical engineering. Here, he invented the "Edison Printing Press." He dedicated the printing press to the manager of a large Wall Street company. He wanted to ask for $5,000, but he lacked the courage to say it. So he asked the manager to give him a price, and the manager gave him $40,000.
While inventing the phonograph, Edison finally made a breakthrough in the research on electric lights after numerous failures. On October 22, 1879, Edison ignited the first electric light with widespread practical value. In order to extend the life of the filament, he tried again and tried more than 6,000 fiber materials before he found a new luminous body - Japanese bamboo filament, which can last for more than 1,000 hours, achieving the purpose of durability. In a way, this invention was the pinnacle achievement of Edison's life. He then created a power supply system that allowed distant lamps to distribute power from a central power station, a major technological achievement.

Why are there white clouds floating in the blue sky...
When he was 5 years old, one day, Edison suddenly disappeared. Dad was so anxious that he looked around and finally found him squatting in the chicken coop!
"What are you doing here?" Dad asked strangely.
"I'm hatching chicks." Edison answered seriously. It turned out that the day before, he saw a hen lying on an egg and hatched a chick, so he wanted to try it himself to see if he could hatch a chick.
Dad pulled him up angrily and funny, and said to him: "Silly boy! You can't hatch chicks! Let's go!"
Little Edison wrinkled He frowned and asked dissatisfied: "Why can't I hatch chicks, but a hen can?"
Edison was such a curious child. He wanted to know everything and wanted to try everything himself. try.
Another time, he found a wild nest on the garden fence. Ah, what's the mystery here? He cautiously looked inside, and it seemed that Feng'er wasn't at home. What a great opportunity! He thought: Today I want to see what is inside the wild honeycomb. He picked up a stick and stabbed it inside. This is bad! A swarm of wild bees flew out of the nest with a buzzing sound and rushed towards him. Suddenly, Edison's face swelled as much as bread, and he dropped the stick and ran away in pain.
He often went to nearby sawmills and shipyards, and was particularly interested in the various tools there. He always liked to pester the master workers and ask questions. Sometimes, others could not answer the questions, so they had to say, " have no idea". He didn't give up and asked, "Why don't you know?" Edison was such a child.
When Edison was 7 years old, his family moved to Port Huron, Michigan. There he went to school.
At that time, the school only offered three courses: reading, writing, and arithmetic. In class, the teacher's lectures were boring, but he often punished students with wooden boards. However, Edison likes to break the casserole and ask questions. He often asks the teacher to be speechless and speechless. The teacher became angry and often called him a "fool" in public.
Edison couldn't bear the insult. He returned home with tears in his eyes, told his mother about his grievances, and said he would never enter the school gate again.
His mother had been a teacher and knew education methods better. She sympathized with her son's situation and said angrily:
"Teachers can't treat students like this!" She took her son's hand, found the school, and blamed the teacher: "You can't teach such students well. It shows that you are incompetent! I want to educate him myself and show you what kind of person he can become!" In anger, his mother dropped out of school. From then on, Edison left school.
When he got home, his mother called him by his nickname and said to him seriously: "Tom, from now on, I will teach you to read. Are you determined to learn well?"
Mom's words deeply touched Edison's heart. With a rare serious expression, he replied: "Mom, don't worry! I will study hard and make a career in the world when I grow up!"
Edison was very diligent and studious. With his mother's specific guidance and patient help, he carefully studied English, arithmetic, chemistry, geography, history... Among them, chemistry was the most attractive to him. He tried every means to find chemistry books and spent all his pocket money to buy experimental equipment and medicines.
The cellar of his home became his "laboratory". On his homemade wooden shelf, there are more than 200 bottles containing various medicines. Every day after he finished his lessons at his mother's place, he quickly ran into the cellar to do his beloved experiments. This was the happiest thing for Edison.
One day, Edison looked up and saw birds flying freely in the sky, so an idea came to his mind: Birds can fly, why can't people fly? Can you think of a way to let people fly into the sky? He was thinking and suddenly thought: If a person's body was filled with gas, wouldn't it also rise to the sky like a balloon? After careful observation, Edison discovered that there was a kind of medicinal powder that could produce gas. He was so happy that he mobilized his friend Mijili to do an experiment. Edison gave Midgeli a large dose of medicinal powder to drink. After a while, Midgeli was rolling on the ground with stomachache, crying loudly, which alarmed the whole family. After asking about the situation, his parents were very panicked and quickly called a doctor to save Midgli's life. Dad was so angry that he whipped Edison hard with a wicker whip. But while Edison was being beaten, he was still thinking in his heart: "Midgery has already halfway through the experiment, but he refuses to bear it, what a pity!"
Edison's recklessness made his mother very angry. She thought, these chemicals Most of the medicines are poisonous. If you eat them casually, your life will be in danger. Little Tom is so ridiculous! So she angrily scolded: "You are not allowed to use this cellar anymore, and you are not allowed to conduct experiments anymore.
" Edison was so anxious that he almost cried. He felt that he had done something wrong, and he was afraid that his mother would not allow him to do the experiment, so he begged his mother bitterly: "If I don't do the experiment, how can I study knowledge? How can you make a career? "
After hearing what her son said, the mother couldn't help but be secretly surprised. It turned out that the child's vow was not just said casually, it was his ambition engraved in his heart. The mother withdrew the ban, and Edison's first The chemistry laboratory continues to exist like this
E. The story of Edison’s invention of the electric light: 300 to 350 words
The story of Edison’s invention of the electric light:
Edison. He and his assistants tried several times with platinum. However, although this kind of platinum with a higher melting point extended the lighting time of the electric lamp a lot, it still had to automatically turn off and then light up from time to time, which was still not ideal.
Edison was not discouraged and continued his experimental work. He successively tried barium, titanium, indium and other rare metals, but the results were not very satisfactory.
Next, he and his assistants. The 1,600 heat-resistant materials were classified and tested, and platinum was the most suitable. Due to the improved air extraction method, the life of the vacuum inside the glass bulb has been extended to 2 hours. The lamp is too expensive. Who is willing to spend so much money to buy a lamp that can only be used for 2 hours?
When Edison saw this scarf made of cotton yarn, an idea suddenly came into his mind. Thoughts:
Yes! The fiber of cotton yarn is better than that of wood. Can this material be used?
He hurriedly pulled off a piece of cotton yarn from the scarf and carefully removed the charcoal. The wire was put into the glass bubble, and the effect was really good.
Edison was very happy. He made a lot of carbon wire made of cotton yarn and conducted many tests to extend the life of the lamp by 13 hours. 45 hours.
"I hope it lights up for 1,000 hours, 16,000 hours!" Edison finally chose bamboo. After putting it into a glass bulb and turning on the electricity, the bamboo filament bulb stayed on for 1,200 hours!
He finally made an electric lamp that he was satisfied with.
F . Famous stories of Edison
1. As for the reason why Edison dropped out of school, everyone knows that it was because Edison asked, "Teacher, why does one plus one equal two?" The teacher said, "Edison, take a pencil and add another." If you add one pencil, wouldn't it become two pencils?" "But teacher, take the water from two cups and put it into another cup. The water will be concentrated in one cup. How can one plus one make it? Is it two?" The teacher didn't know how to answer.
"Teacher, two pieces of mud stick together and become one piece. Why does one plus one make two? Maybe one plus one makes one. At this time, the teacher got angry: "It's so annoying! You can go and think about it yourself." "So the teacher continued the class. Edison raised his hand again, "What's the matter, Edison?" The teacher suppressed his anger and asked.
"Teacher, why does the wind blow?" "Teacher, why do eggs hatch? A chick?" The teacher said, "That's because the hen warmed the eggs. "Teacher, why can chicks hatch by heating eggs?" Edison asked many more reasons, such as "Why don't fishes drown?" "Why is the sky blue?"
Why did the teacher finally couldn't bear it anymore and scolded him severely: "It's so annoying, ***, I'll learn your arithmetic honestly! Are you a fool? Reading like this is a waste of time." Edison went home crying. After listening to her son's story, the mother took Edison's hand and went to the school to find the teacher. She asked the teacher: Are you saying that my son is a fool and is reading in vain? The teacher was speechless.
"I understand. I can educate my son by myself. No need to bother the teacher. Goodbye." Holding her son's hand and going home, Nancy thought as she walked, "Mr. Engel forced the child to read the textbook." After memorizing it completely, my son felt disgusted and the two of them reached an impasse. I didn't force him, I wanted to enjoy the joy of thinking with him.
To hell with memorizing the contents of the textbook! Memorizing textbooks is useless when you grow up. Aren't living textbooks everywhere?" Nancy vowed secretly: "I will give my son an education that will never lose to other children." From then on, Edison's family education began.
2. Once, when he saw a hen hatching eggs, he curiously asked his mother: "Why is the hen sitting on the eggs motionless? Is it sick?" His mother told him that this They are hatching chicks, and after a few days, the baby chickens will emerge from the eggshells. "
After listening to his mother's words, Edison felt very novel. He thought, a hen can hatch chicks by lying on an egg. How does an egg become a chick? People lie on it. Can it work? He decided to give it a try. Edison brought a few eggs from home and found a secluded place at a neighbor's house. He first built a nest, spread it with soft thatch, and then laid out the eggs. Squatting on it, he wanted to see with his own eyes how the eggs hatched into chicks.
It was getting dark and Edison hadn't come home yet. Everyone at home was very anxious, so they looked everywhere. After searching around, he found Edison sitting motionless on a grass nest with many grass blades on his body and head.
When I saw him, I was angry and funny, so I asked him: "What are you doing here?" "I'm hatching eggs here! The chicks are about to hatch. "What kind of eggs are you hatching? Come out quickly!" Dad shouted loudly. "The hen can hatch eggs. I want to see how to hatch chicks." "No, no! Go home quickly!" Dad shouted again.
Mom did not blame or make fun of him, because she knew the child's character. She smiled and said: "Human body temperature is not as high as that of a chicken." If your body temperature is high, you won't be able to hatch it if you hatch it like this. "Although Edison did not hatch the chicken, he increased his knowledge through this egg hatching activity.
3. Edison saw the birds flying freely in the sky and thought, if birds can fly, why do people Can't fly? Can people be given wings? He suddenly thought that balloons can fly into the sky without wings, so is it possible to inflate the human body? So he found a kind of powder that can produce gas, and let a person The little friend drank it to see if he could fly like a balloon.
But after a while, the little friend got a stomachache and cried loudly, and almost died because of this. , his father beat him hard and said he was not sure what experiments he would do in the future. But Edison was still unconvinced and said, "How can I know if people can fly if I don't do experiments?"
4. One snowy night, Edison's mother suddenly fell ill, and his father hurriedly called the doctor. The doctor said: "Your mother has acute appendicitis and needs surgery." "
At that time, there were only oil lamps and no electric lamps. The light of the oil lamps was very dim, and if you were not careful, you would open the wrong knife. Edison suddenly thought of a good idea. He took out all the oil lamps in the house, and then opened them. A mirror was placed behind the oil lamp, allowing the doctor to complete the operation smoothly.
The doctor said: "My child, you saved your mother with your wisdom and cleverness!" Edison took his mother's hand and said. : "Mom, I want to create a sun at night.
5. Edison was a famous British scientist. Edison studied very hard when he was a child. Once, Edison's mother was sick for several days and asked Edison to sell vegetables in the market. For the sake of his mother's health, Edison stopped going to school and went to the market to sell vegetables, so he thought: "If I bring a few books to read, that would be the best of both worlds."
When he went to the market, he He was selling vegetables and reading at the same time. He only concentrated on reading and not selling vegetables. It didn't matter how much others paid anyway, and others could take the vegetables as they pleased. Another time Edison made a light bulb. He searched many places to find a filament before he found it. He sold newspapers on the train to get money to buy the materials for making it.
Once when he was doing an experiment on a train, he accidentally knocked over two bottles of chemicals and caught fire. He was kicked off by the commander and his chemicals were also thrown down. So, he went to find a small dilapidated house as an experiment house. He worked on it non-stop for several days, and the electric light experiment finally succeeded. Edison studied hard like this before he became a famous British scientist. I want to learn from Te that I have loved and studied science since I was a child, and I want to be a scientist when I grow up.

I. One of Edison's The story (one is enough) is about 300 words
This story is very famous: when Edison was 8 years old, he successfully used his wisdom to save his mother.
At that time, Edison lived in a small mountain village in the United States. One night, Edison's mother suddenly had a stomachache and rolled on the bed. Edison's father hurriedly rode to fetch a doctor. After a while, the doctor came and after diagnosis, he concluded that Edison's mother had acute appendicitis and needed immediate surgery. But there was no kerosene lamp at home, and the doctor said the light was too dark to operate. Edison's father was jumping around anxiously, and Edison's mother was sweating profusely in pain. Little Edison thought about it and remembered that he and his friends were playing with lenses this morning. The lenses would reflect when facing the sun. Thinking of this, Edison ran out like a gust of wind and borrowed four large mirrors and a kerosene lamp from his neighbor's house. Putting the kerosene lamp in front of the big mirror, the room suddenly lit up. The operation was successful and my mother was saved. Dad praised Edison as a smart child.
This story tells us that to be a thoughtful person in life, we must also learn this kind of wit from Edison!
