My deskmate is a thin boy, short, with a sharp head and particularly prominent eyes (because I used to wear glasses, I just had surgery to take them off). Such an unremarkable thin boy often brings some surprises to everyone. That pointy little head contains a lot of things that no one knows. Also won the second national youth network popular science activity picture award! Therefore, the teacher gave him the nickname "Little Scientist"-he is my deskmate Guo Yongbiao.
One day after class, he began to nag in my ear again: "Hey, have you ever heard of violent bear?" I shook my head curiously. He immediately spoke cheerfully: saying that his mother went to Shenzhen to buy him a bear doll, which is a blessing to God and can keep you safe; It is also said that there is also a violent bear on the Internet, called Bobo Bear for short. There are many functions, I can send and receive emails, I can make all kinds of cute actions, and there are also men and women ... I am also a little touched by his fantastic story, and I especially want to have a pink violent bear of my own.
The most interesting and exaggerated thing is that he once said that his mother had been to a restaurant by the Huangpu River in Shanghai. It is said that there are all buffets, such as abalone, all kinds of Haagen-Dazs, especially Haagen-Dazs cakes. Every time he says something delicious, he will keep waving his hand and say, "eat as much as you want!" " "It's interesting, as if he had been there.
It is also said that there is a kind of German chocolate in Shanghai, which is just as delicious. It is said that people in Hong Kong and Shanghai eat it as pickles! Ha ha ha, we are so funny! Do you have such delicious pickles?
However, Guo Yongbiao has been to Shenzhen and many other places! That day, as soon as I heard that I was going to Hainan, he immediately gave me an idea that I should go to Sanya instead of Haikou. Sanya's scenic spots are the most interesting. He read a lot of books. Once I asked him, "Have you read Dante's Divine Comedy?" He said casually, "Yes, it's boring." You know, I just heard the title of this book! He has seen it. So he does know a lot of things. Often in Chinese class, the teacher asks questions about the new text, and he can tell the celebrity information mentioned in the text without looking through the reference books.
But even such a small scientist has his restless place. Because I am the representative of Chinese class, his homework is the most troublesome every time. Either I don't weigh enough, or I scribble casually, so I don't have fun after class, and I have to help the teacher urge him to do his homework quickly! He has a bad habit of not remembering his homework since the third grade. He keeps all his homework in his clever head, but this clever head can't finish his homework all day. Once, I finally finished writing an article with enough words and relatively complete text, but the content was also wrong! Haha ~ Do you think it will make people laugh and cry?
He also has a shortcoming, that is, he often plays practical jokes with Liu and other male students. Once, in a computer game, they gave the beautiful Mona Lisa plastic surgery, with long ears, thick eyebrows, upright hair and prominent eyes. They turned the beautiful Mona Lisa into an ugly old woman and printed it out for everyone to enjoy their masterpiece.
Worst of all, once, when I was doing my homework, he gestured a Q with his hand and slapped me angrily. I asked him angrily, "Why did you hit me?" He said, "I didn't hit you, I hit the person next to you through you." I said, "You can't pass me?" He said: "I am afraid that the scope is too large and the teacher will find out!" "
Look at him. He is very glib, isn't he? However, on the whole, I admire him for knowing so much knowledge. It would be better if he could write better homework in the future.
Chen Jing is my classmate. There seems to be a small motor on her head, which keeps turning. She loves science very much and is what her classmates call a "little scientist".
Chen Jing likes quiet, just like her name, but she is very active in science class. She likes to do small scientific experiments. Her interest elective package is like a small museum, with a magnifying glass, a compass, a small rocket, a small model airplane … everything. One day, the teacher finished the magnifying glass unit and just announced the class was over. She jumped up from the chair, took out a magnifying glass, and concentrated the sunlight on a piece of white paper. The light spot the size of a red bean is hard to see, but she still looks at it with great interest and carefully adjusts the focal length. "Smoke, it's working!" The sound startled the students around. Chen Jing held the smoking paper high, skipping, his eyes wide and his mouth closed. It's like discovering a "new world". But she suddenly frowned and rolled her eyes, so she took out a black pen and blackened the paper three or five times. I asked her what she wanted. She said to me, "Try the black one. Is it easier to absorb heat? " She continued to focus the light with a magnifying glass. After a while, the paper creaked, and a smell of paste came to my nose, almost burning. Just then, the bell rang, and she quickly packed up the experimental equipment and put it in her bag.
Last month, I suddenly found another thing in her bag-a small and exquisite homemade humidifier. I asked her, "Who made this thing?" "I did it in an elective course of interest." I used to think she was very quiet, but I didn't expect her to have such skill. I studied the humidifier carefully and asked her, "Does this work?" She said excitedly, "Don't you believe it? Then let's try it first? " With that, she put a small glass of water into the humidifier, then turned off the machine, turned on the switch and waited. She hummed a ditty and beat the time rhythmically, which seemed very leisurely. After a while, the humidifier sprayed wet white gas. Looking at this humidifier, Chen Jing grinned happily and said proudly, "Can I do it?"
Chen Jing was completely fascinated by science. She is really a "little scientist". I admire her very much! I believe she must be a woman "Edison" when she grows up!
Recently, I saw an experiment about the surface tension of water on the Internet.
This experiment mainly covers a porous paper on a bottle filled with water. After the bottle is turned upside down, the water in the bottle will not flow out of the hole. This can't help but make me curious: what is the reason why the water in the bottle won't flow out of the hole? So, with this curiosity and a trace of disbelief, I decided to do my own experiment to see if what I said online was true. According to what I said on the internet, I prepared everything I needed for the experiment: a bottle; A needle; A piece of paper; Some water. The experiment began: I first poured water into the prepared bottle, poked many holes in the paper with a needle, then covered the paper with holes on the bottle mouth, pressed the paper with my hand, and carefully turned the bottle upside down so that the bottle mouth was facing down and the bottle was facing up. Finally, I moved my hand slightly to the right.
At this time, an incredible scene appeared: the paper was still close to the bottle mouth, and water did not flow out of the hole. This scene immediately blindsided me: did the water really not flow out of the hole? ! This is really amazing! Later, I looked it up on the Internet and finally understood the reason: the original punched paper can hold up water because of atmospheric pressure, which leads to the upward pull of the producer, and the water will not leak out of the hole because of the surface tension of water. Water forms a film on the surface of the paper so that it won't leak out. Just like an umbrella made of cloth, although it has many small holes, it still won't leak rain.
Hehe ~ the world is beautiful and science is wonderful!
The progress of mankind must not ignore an important role-scientist. He has made endless contributions to mankind. If human progress is a treasure house, then scientists are a bright pearl.
If I were a scientist, I would build a "floating house" for mankind. Then I will electrify the house and make it fly. The explorers must be very happy. However, as a result, several people are unhappy-earthquake, subsidence, flood. Although not convinced, I still have to admit defeat.
If I were a scientist, I would be a steel Metallic Attraction Kungfu Cyborg. It is not only a policeman, but also a fireman and a cleaner. His energy is infinite, so don't worry about running out of energy at work. Thieves, demons and rubbish there will sigh one after another. ...
If I were a scientist, I would create many "artificial clouds". I will let the arrogant heat bow its head, let the young tree hold its head high, let the depressed people be full of happiness, and let the bully who makes a fortune by water be full of despair.
If I were a scientist, I would ...
Although I know this is a dream, how much I want to be a scientist! Grasping today is controlling the future. Fight with me for the future of mankind!
My grandmother lives in Xiaoshan reclamation area and has a chicken farm at home. Every time I go to her house, there are always chickens and eggs on the table.
One day last year, I went to my grandmother's house. I saw a plague among chickens there, and many of them died. My grandmother is too distressed to eat. I accidentally cut down a cactus and fed it to a plague-ridden chicken. Before long, we found that the chicken became energetic and had an appetite. After examination, the disease of this chicken was basically eliminated. Looking for the reason why this chicken recovered, everyone thought that cactus probably played a role. At this moment, I remembered the teacher once said that in China medicine, many plants can be used as medicines to treat some diseases.
In order to find out the real reason, my cousin and I began to investigate chicken farms. We know that many chicken farmers are also trying to cure diseases such as chicken plague with cactus.
So, what is the relationship between cactus and chicken plague? After consulting materials and visiting experts, we finally learned that the stem of cactus contains quercetin, glucose, resin, tartaric acid and protein. The stems and leaves also contain triterpenes, malic acid, succinic acid and 24% potassium carbonate. Quercetin and tartaric acid have antibacterial effects and are the bane of chicken plague. At this point, we understand why cactus can cure chicken plague, and we are also amazed at the magical effect of cactus.
In order to further determine the best usage and dosage of cactus in treating chicken plague, we did another experiment.
First, we took 20 sick chickens from the chicken farm and divided them into 5 groups with 4 chickens in each group. Take some fresh cactus, cut off the prickles on the epidermis, wash them, and squeeze them out with a juicer. Finally, a certain amount of cactus juice was mixed with a certain amount of feed in the dose cup, and then it was fed to chickens, which achieved different effects on different doses of five groups of sick chickens.
The experimental results show that the fourth group has achieved the best effect, that is to say, the treatment effect of taking 4 grams of cactus juice in the morning and evening is the best. From this, I think that if cactus is made into a drug to prevent and treat chicken plague, it will have a very good effect and reduce the pollution caused by synthetic drugs. Because cactus is easy to grow, it can also save a lot of manpower and financial resources, and it is popularized quickly and has excellent market prospects.
We love science, science can't be separated from life, and life can't be separated from science. Science is like a jungle bigger than the universe. We keep exploring and discovering in the jungle, but if we stay in this jungle for a long time, we will inevitably find new jungles and continue to explore. This is a new science that we have discovered. Only by continuous exploration and discovery can we find these new sciences that are useful to society.
I have known the importance of science since I read the book Popular Science. Whether people realize it or not, science and technology have deeply influenced our daily life and played an indispensable role in economic and social development. If people don't explore, they won't have mobile phones. If you don't have a mobile phone, how can you keep in close contact with your family and friends at will? I can only write to them, and I won't receive the letter for a week. What a long wait this week! Without the internet and computers, how can we find so much information? We can't send a short message to foreign friends within 1 second, and we can't travel in the ocean of the internet. What a great loss! Therefore, human beings should explore new science, and these things should be left to the flowers of our motherland-teenagers to complete.
The book of popular science is divided into several sections: special attention, science and technology information station, demonstration of comprehensive practical ability, I am a young scientist, relay of popular science animation, learning by doing and exploration and discovery. Don't underestimate these plates, there are many contents inside! It tells us a lot of interesting scientific knowledge, including the causes of desert formation, drought-resistant strategies of plants, knowledge of pm2.5 and so on.
Popular science tells us a lot of scientific knowledge, and I will always like it.
In 20xx, I was a 30-year-old adult. Because I like ancient stories since I was a child, and there are still many unsolved mysteries in ancient times, I decided to invent the "time machine".
First of all, I want to see the materials. When I was reading Einstein's theory of relativity, I found that it said, "When the speed of a car exceeds the speed of light, time may go back." So I decided to do this.
In 20xx, my assistant Zhu and I installed our own accelerator on my Mercedes-Benz, and then put many high-energy particles into the accelerator, so the world's first time shuttle was built.
Zhu and I took the time shuttle by helicopter to the Sahara desert to prepare for the experiment. I sat in the driver's seat. Zhu checked the time shuttle and sat in the co-pilot seat, ready to go. 20,25,28,29,30! It has reached the speed of light of 300,000 kilometers per second! 35,40,50! It has reached 500 thousand kilometers per second! Suddenly our eyes blurred and we fainted. . . . . .
When we woke up, I found that we landed on the shady lawn. In front of us is a monster about 20 meters high. This is Mamen Xilong. I looked at the time and found that we had reached BC 1. 500 million years later, dinosaurs became extinct. Suddenly a comet landed 0/00 km away from us/kloc-,which triggered a volcanic eruption. When the magma was about to fall on the shuttle, we drove it back to the present.
We reported this discovery to UN Secretary-General Deng, who won Zhu and me the 20xx Nobel Prize in Physics. The Royal Society also invited us to become members, and I became the president. I applied for a patent for this time shuttle to make it flow into society and be bought by more people.
All this reminds me of Li Ning's famous saying that "anything is possible".
Everyone has their own colorful dreams and ideals in their hearts. Ideal is an inspiring goal, which will take you to the other side of success. Without ideals, it is like a ship that has not reached the beacon. Without ideals, you will lose your way in the ocean of knowledge. My ideal is to be an astronomical scientist and explore the mysteries of the universe.
Scientists are an extraordinary profession. Scientists like Newton, Edison and Einstein have great influence on the scientific community. I admire them very much, so I want to be an astronomical scientist, discover creatures on Venus, observe distant planets and explore the real universe.
I spend more and more time at school and learn more and more. I learned a truth: success = hard work+confidence+talent. Only in this way can I realize my ideal. A person has an ideal. If he doesn't stick to it, it's no use trying again.
I know it is not easy to realize my ideal. Therefore, in order to realize my dream, I often go to the book mall to read books, and I often read some books about science, such as The Unsolved Mystery of the World, from which I know that scientists have discovered the ruins of the city on the surface of Venus and suspect that Venusians live on it. My sister borrowed a classmate's book about aliens, and I rushed to read it. From it, we know that alien technology is very developed and there are already earth tour groups. They can make biochemical people. Aliens only have four fingers, and biochemical people have six fingers. They can learn the language of a country in a short time. There are more than 60 alien bodies in the United States. The United States caught an alien who traveled to the earth more than two meters high, and Mexico caught an alien who was less than one meter. The United States dissected aliens, who visited a farmer's house in China, took the farmer away and sent him back. A sentry was caught. In just a few minutes, the time of his watch passed five days. China has discovered many times that alien ufo has visited the earth. ...
"As long as the kung fu is deep, the iron pestle is ground into a needle" and "spring water cannot be picked up, and learning cannot be learned". I am confident that I can walk through the traffic jam to pursue my ideals, realize my dreams and win glory for my country. "The sky is high for birds to fly, and the sea is wide for fish to jump." I want to spread my ideal wings and fly to the sky!
