Fan Wener: How many people in this society like to read popular science works now? Everyone thinks science popularization is boring. However, popular science brings us a wonderful world!

Yes, although fairy tales are fascinating. However, fairy tales are fairy tales after all. Most young readers do not intend to deeply understand the author's writing techniques, nor how to feel the truth, goodness and beauty in the world, or know the truth of life, but simply read stories. After that, what will books do and learn nothing? Isn't this against the original intention of reading?

However, popular science works are different. Popular science works have brought a lot of popular science knowledge to our children. If we know more about popular science, we will talk endlessly with others, so that other children will feel that this person knows more and has knowledge, which will definitely make them admire. Moreover, we can apply the scientific knowledge learned from books to practice, which will bring convenience to our lives. Isn't this wonderful in the field of popular science?

Premier Zhou has a famous saying: Work with courageous people instead of reading. The world of popular science refers not only to the knowledge in books, but also to the discovery of scientific mysteries in wonderful nature. Newton discovered gravity because an apple fell on his head; Darwin gradually became the greatest biologist in the19th century, because he liked to observe some flowers, plants and small animals when he was a child. Presumably, everyone knows about giant insects! What does it depend on? It is careful observation and superb technology! And so on. These examples abound.

So what does science bring to our children? It is the standard of knowledge, culture, science and human progress! With knowledge, you can stand firm in society; With culture, we can enrich our thoughts; With science, we can stand on the top of the world and make progress! Now we must master scientific knowledge and serve the motherland when we grow up. Let's March into science together!

Fan Wensan:

Science is often inseparable in our life, and everything in our life is related to science. Looking back at the old society in the 1970s and 1980s. At that time, there were no color TVs, air conditioners and refrigerators, which brought a lot of inconvenience to people's lives. In terms of transportation, there are no planes and highways, and now an hour's journey from Hangzhou to Xiaoshan seems so far at that time.

Now think again, we are immersed in the world of computers and televisions almost every day and feel the convenience they bring us. With the computer, we can check the information online at any time; With TV, we can keep abreast of the news; In hot summer, air conditioning can bring us cool ... anyway, it is inexhaustible. In a word, the changes brought by popular science are endless.

1970, China launched China's first artificial satellite "Dongfanghong-1" with the Long March-1 rocket. How can it not be exciting when the rocket rushes into the blue sky and sends the satellite into an elliptical orbit hundreds of kilometers high? This satellite launch marks that China's launch vehicle technology has entered the advanced ranks in the world. China's space technology will be more advanced and powerful!

In science class, I learned about the methods of ancient people making paper and inventing gunpowder, and tried to make paper by myself. Seeing the fruits of my hard work, I can't help but sigh: the wisdom of the ancients has brought convenience to our modern life. In normal times, what we see is an ordinary blank sheet of paper. In ancient times, I don't know how much effort they made and how precious paper and pens were. It can be said that paper media is hard to come by.

Grandpa Yuan Longping has developed better rice for us and made us eat healthier. The development and success of the space industry shows the leading level of China's space industry. Great changes in human society cannot be separated from science, which has brought us a better life today.

In our daily life and the embrace of nature, there are also many popular science animals and problems that interest us. For example: Why do koalas like to sleep with tree trunks? Are termites relatives of cockroaches? Wait, three days and three nights can't be finished.

I like animals, I like to go to the zoo to see the naive giant panda, I like to observe ants in the community green space, and I also like to feed the white rabbits at home. While observing small animals, I also discovered the secrets of nature and noticed its ecological environment. With these findings, I think I should protect and care more for animals and the environment, so that they can have a beautiful home.

Popular science has brought us great changes and greatly improved our lives. At the same time, in a popular science learning place like nature, we observed the dwellings and habits of small animals. Let us know more about nature.

Science popularization is great, science popularization is endless, and science popularization is the teacher who takes us into the learning classroom.

Popular science is beautiful. |||

Move to the moon

Yang Ziqi ancient city primary school

We are challenging, challenging an unprecedented life-Inscription

Today is another happy day. From then on, a new invention was born in the air-a bridge can lead to a beautiful planet. Suddenly came the voice of the broadcast: "Please ask the next batch of settlers to get on the bridge." Everyone rushed to the bridge, and everyone flocked to it. I was pushed up in the crowd. People are in high spirits, and their enthusiasm for happiness is so strong. Someone stepped on my instep, and I gnashed my teeth in pain, but I got carried away and squeezed into the cabin with the crowd. Because I want to live in my second hometown-the moon. In a short time, the spacecraft started, and we entered the first stop in space-the moon.

When I arrived at the moon, my eyes lit up. I couldn't believe my eyes. Ah, the moon is so beautiful! This is no longer a bare mountain. Take a closer look at where Chang 'e lives. It is really a paradise on earth! I saw the sunshine, white clouds against the blue sky, the breeze blowing gently, birds chirping, trees shaded and lush. People removed flowers and trees from the earth. These trees are flourishing, flowers are in full bloom, and people take a leisurely walk and chat under the shade. "Today's invention is really good. We can finally play on the moon like the Goddess Chang'e flying to the moon. " "What's the name of the spaceship we just took?" "Call a spaceship." ..... I talked to them for nearly an hour. "Why is there air on the moon and these plants grow so well?" I was puzzled and asked with my eyes wide open in surprise. A tall doctor with glasses said: "This is developed by removing air from the earth and purifying it with vos technology, which is convenient for saving oxygen and energy." "Oh," I nodded puzzled.

Unconsciously walked into the hospital, the nurse smiled and said, "Little friend, are you here to see a doctor?" "No, I'm here to visit." I suddenly "asked": "What if the people who live here are sick?" "We have a special medicine here, which uses the water and soil nutrients on the moon. After drinking the medicine, patients will feel refreshed and all diseases will disappear. " She blurted out. "Shrimp!" I was dumbfounded. "Medical technology is super advanced." Nurse Kan Kan said: "Recently, we have developed a drug to control cancer, which will make patients out of danger within 24 hours and eliminate cancer cells in the human body. This drug will come out soon." "Haha, then human beings can live to be one hundred years old, or even two hundred years old." I cried with joy.

After coming out of the hospital, I went to Mars to play again, so I took the F702 UFO. I pressed the switch, and in the blink of an eye, "How fast, how fast …" I boasted over and over again. Oh, no, today is Wednesday. I have to go to class. What if there is no schoolbag? Don't worry, because I have a "super ruler", small, just hide it in my pocket. All the learning materials are stored in the "super ruler". As long as I pull out my ruler, there will be a teacher giving me a lesson on the small screen. What's the matter, novelty? In the evening, I want to sleep What should I do without a house? I pressed the button of a model room next to me, only to see the model room getting bigger and bigger, and suddenly it became a five-star suite, so gorgeous and magnificent, just like a palace. When the door opened, a robot came over and said politely, "What's your order, master?" "I want to eat and sleep after eating." Just after that, a rich and delicious meal fell from the sky, and the meal made by the "automatic food maker" was immediately placed in front of me. I have a big appetite and eat with relish. After eating, I went to bed beautifully.

Just after waking up, an alien suddenly appeared with a big head and a small body. How interesting! He looked at me and smiled and said, "Please sit on the CKBI UFO. We are going to travel. " Sitting on the spaceship, I didn't know it, but when I saw it, I was shocked: Look, there are colorful planets, which are shining with crystals, fluorescent and eye-catching. There are many museums in different countries on different planets. I found the China Museum, where I found many precious historical materials and cultural relics, such as Five Thousand Years Up and Down and Romance of the Three Kingdoms, which was an eye-opener. Soon after, I visited the Space Resort, where the Tianhe River was shallow, with colorful lights flashing and colorful stars floating on it. There are beautiful elves on the stars, lively, lovely and naughty, jumping around, and I enjoy swimming in the galaxy. ...

Ah, what an exciting and refreshing day! How I wish I could live such a happy life every day! "Goodbye shen! Goodbye, I will come back again. " I reluctantly bid farewell to the space planet.

Which animal is the cleverest?

Linhai Zhejiang merchants modern experimental primary school

The animal square in the animal kingdom is decorated with lanterns, and even the lion king comes in person. What makes everyone so happy? It turned out that the annual knowledge contest began.

The master of this competition is like a cloud! For example, Dr. Chimpanzee, Master Dolphin who went abroad, Mr. Elephant, Crow ... With the parrot owner's command, the elites in the animal world began to write examination papers.

After a fierce confrontation, three intelligent stars stood out, namely Mr. Dolphin, Miss Crow and Dr. Chimpanzee.

"The following is a five-minute free speech. "The parrot owner said.

The first one who came to the stage was Miss Crow, who said with great enthusiasm, "Although I am called crow's mouth by human beings, we crows have a high IQ. Crows living in the city can throw nuts on the road and let the bus crush them, then we can easily eat delicious nuts ourselves. And those crows who live in the forest risk their lives to feed in the forest every day, because there are many traps set by hunters in the forest, but if we are trapped for the first time, we will never be trapped for the second time. Moreover, some talented birds among us can speak human speech, unlike parrots who can only learn words but can't speak. Please vote for me! "

The next contestant is Mr. Dolphin: "We dolphins are an advanced and intelligent mammal. Don't say I'm bragging. Except for people, our brain is the largest of all animals. We dolphins often save people who fall into the sea, even I have saved three people. We learned dolphins can not only learn from others, but also learn many languages at the same time. If I think about it, I can have a Chinese conversation and know about 300 English words every day. Some people compare us with chimpanzees. Someone put a piece of metal on my head. I can take it off 20 times like a chimpanzee, but that chimpanzee needs 90 times. We dolphins not only have strong learning ability, but also have high reaction ability. We dolphins will take different measures to deal with different situations: for example, we will be friendly to people, show a very gentle and amiable appearance, and play with them. As for sharks, we will hit them with our noses, because sharks are cartilaginous animals and can't afford to hit them. How's it going? We dolphins are very smart, please vote for me! " Mr. Dolphin bows.

Finally, the most powerful Dr. Chimpanzee calmly walked onto the stage, pushed the glasses on his nose and said, "Hello, everyone knows that we are the closest to humans, and we are all primates, with a genetic similarity of 98.77%. Some scholars believe that we should belong to human beings. From this point of view, I think I am the smartest, and because we are smart, we can make tools-folding. " We have feelings, and we will feel sad for the death of our companions. We are self-conscious. When we look in the mirror, we know that the guy inside is not a strange chimpanzee who has come to grab territory, but himself. Some of our companions, including me, can guess their thoughts and do something selfless or selfish. My speech is over, thank you, please vote for me!

After ten minutes of secret ballot and statistical results, the host parrot finally announced that Dr. Chimpanzee had won the animal with the strongest intelligence and Mr. Dolphin had won the animal with the strongest learning ability.

A wonderful trip to Mars

Chen Qianqian linhai primary school

In the morning, a melodious music woke me up from my dream, and the smart mattress gently pushed me out of bed. I got up and stretched myself and complained, "You stupid machine, why did you wake me up so early?" "Master, have you forgotten? You are going to travel to Mars today! " My robot nanny said while pushing the dining car. Oh! I remember! Yes, my father and I booked a trip to Mars today!

I had a quick breakfast and walked to the lawn of the roof garden. Dad has been waiting for me there. Sitting in my father's new flying sports car, I entered the space center in less than ten minutes.

Entering the Space Center, I saw a nuclear-powered spaceship made by China Aerospace Company parked on the runway. It's like a mushroom that just broke out of the ground, and its round nano-carbon fiber shell has a metallic luster. This spaceship is powered by nuclear energy and can orbit the solar system once. The flight speed can reach 6.5438+10,000 kilometers per second.

"Hello, welcome to join the Mars tour group." Miss robot space flight came to me. She dressed me in a spacesuit, led me to my position and fastened my seat belt. Is so kind and easygoing. With a loud noise, the spaceship flew away from the earth and entered the fascinating outer space world of vast expanse. In a flash, we are getting farther and farther away from the blue earth. Spacecraft flying in the deep space, countless stars shining like bright street lamps, as if to say: "Welcome-friends from the earth."

Some stars are far away from us, and some fly by us. I seem to reach out and pick one and hold it in my hand.

At this time, the robot guide in the spaceship is introducing the situation of Mars and the scenic spots that can be visited. "ah! I read in a book that Mars is not a desert. Where are you from? " I asked strangely. Dad said, "That's an old almanac!" Five years ago, humans put a big mirror on the edge of Mars, which reflected sunlight and melted the lake of dry ice (dad said it was a solid form of carbon dioxide) on Mars. After the melting of the dry ice lake, carbon dioxide formed an atmosphere similar to that of the earth on Mars, and the excess carbon dioxide produced a greenhouse effect, which made the surface temperature of Mars rise and dissolved the water ice under the surface, forming an ocean. Today's Mars is no longer a barren land, but another earth, full of vitality. Now many earthlings have moved to Mars. Mars has also become a transit point for solar system travel! "

After 10 hour flight. The spaceship landed in the space center of Mars, and I walked out of the porthole of the spaceship and set foot on this fresh land. An indescribable feeling quickly welled up in my mind. The spotless runway, lush trees, fresh air and warm sunshine put me in a warm atmosphere. Suddenly, I got rid of the fatigue of space travel and was full of energy.

Walking out of the space center, the robot guide took us on a self-driving airship and drove on the streets of Mars. I saw all kinds of beautiful and unknown flowers and plants everywhere, and the small building with agate-like light built of unknown materials was particularly beautiful under the shade of flowers and plants. The main means of transportation in the street is the intelligent land airship, which runs fast and steadily, and is self-driving. Tell it the destination. The tour guide said: "This airship uses water as fuel and has achieved zero emissions." "Water can be used as fuel? "I asked. Dad explained, "Of course, water is composed of two elements, hydrogen and oxygen. They can be separated by electrolysis. Hydrogen is collected as fuel, and the generated oxygen is released into the atmosphere for use by animals and plants, which is very environmentally friendly. "

After a day of sightseeing. In the evening, I was both excited and novel. Although I am 0/0 billion kilometers away from the earth, I feel so kind, just like in my hometown. There are stars around, so quiet! The experience of the day reappears in my mind, feeling that the sky is not far away and the land is no stranger. I think technology can change everything, the desert can become an oasis, and the moat can become a thoroughfare.

I believe that the universe will be conquered by human beings one day! Changing Mars is just the beginning!

The future universe is the universe of all mankind! I believe this day will come!

Huang Yu? Pollen rain!

Linhai Zheshang Primary School Yezixi

Hey! Strange, why is it raining yellow? It doesn't make any sense. You know, rain is transparent!

find

It must start on Friday. ...

When school was over on Friday, I went home with Wang Xiaole and stumbled upon this amazing secret. Look! Looking up at the rain in the sky, I feel the color is a bit strange. Then I took a closer look at the water on the ground. Sure enough, the water was yellow and the ground was dyed yellow. What is even more incredible is that even the cars are stained with yellow spots. When I touch it with my hand, I feel it is pink, but when I smell it, it is tasteless. If I don't look carefully, I really can't see it! "Look!" I pointed to the puddle under the big tree. There is a circle of yellow powder around the puddle. When you look closely, almost every big tree is surrounded by such a yellow circle. This situation is really strange, which aroused our suspicion and curiosity drove us to have a look!

explore

Wang Xiaole and I decided to explore the truth separately.

As soon as I got home, I decided to investigate the opinions of my family first. I went to see my father first, but he looked blank and didn't notice the yellow rain today. Alas! It is impossible to explore scientific truth with such a careless person.

At this time, the grandmother sitting on the side chimed in and said, "Yes, I saw it, too. Even the ground is yellow, which is not a good sign. " Looking at my grandmother's mysterious appearance, I sighed: "Alas, my grandmother is so superstitious that it is impossible to explore the truth with her!" "

On the other hand, although my mother was very interested in our conversation, she never commented. She just looked at my anxiety coldly, as if watching from a distance, as if watching how I conducted the investigation alone. ...

Looks like we're on our own!

I met with Wang Xiaole to exchange information about the investigation, but we got nothing.

We decided to "stand on our own two feet", and we must find out the truth. We first ruled out the possibility that the yellow powder was "chalk", and then we thought of the recent "nuclear leak" in Japan. The more we think about it, the more afraid we get. If it is a "nuclear leak", it will be miserable. Now we are talking about "nuclear" discoloration. We don't want this to happen. We decided to look up information on the internet. This is the best method we can think of.

Looks like the truth is getting closer.

truth

It's time to uncover the truth!

We first looked up "radiation rain" on the Internet and found that there is such a thing as "radiation rain": "radiation rain" will pollute food and water, and if the human body comes into contact with rain with high radiation concentration, it will lead to skin ulceration and other symptoms. Fortunately, however, experts claim that radioactive materials leaked from Japan will not float to China.

So, what about Huang Yu?

We searched for the word "yellow rain" again, and our hearts beat faster and faster in the pop-up information. Sure enough, we found the truth! It turns out that it's just spring and all flowers are in full bloom. Under the influence of updraft, yellow pollen such as rape flowers floated into the air and fell to the ground with the rain, which also formed "yellow rain". "Yellow rain" turned out to be "pollen rain"! Experts say that pollen rain is a normal natural phenomenon in spring and will not cause harm to the environment and human body. A few days of hard work finally paid off, and we were both excited and proud.

When I got home, I excitedly told my mother the truth. Unexpectedly, my mother was happier than me. Mom said that what makes her happy is not the truth we finally found, but the spirit of our constant pursuit of the truth, which is the spirit that scientific research needs!

"Is this really the spirit of scientific research?" I'm dubious. It turns out that mom didn't say a word before, just to let us investigate ourselves. Huang Yu? Radiation rain? Pollen rain! Unexpectedly, the investigation triggered by curiosity led to a scientific truth. It seems that science is around us, and careful observation and discovery, continuous investigation and exploration, and finally get the truth, isn't this the spirit that scientific research needs?

Kill "ghosts" and see blood.

Linhai foreign language primary school feizixuan

One late autumn afternoon, my brother and I went to play in the street. Although it is still autumn, the cold wind blows quickly. We came to the street. Oh, this street is really lively! There are rings, toys, learning tools ... this is everything, which fascinates me.

We suddenly saw a man dressed as a Taoist. He shouted, "Come and see! I am in heaven and earth, and I can do anything except exorcism! " As soon as he shouted, people in the street were attracted by his shouts. They surrounded it with three floors inside and three floors outside.

I saw him go into the house and take a sword and a scarecrow. He picked up his sword and began to dance. Suddenly, he sat cross-legged, his sword turned in his hand and he was still nagging. The audience said in unison, "Good!" His eyes suddenly opened and he jumped up. The sword in the right hand flew out like a flying knife, just inserted into the heart of the scarecrow. Strange to say, blood spurted out of the heart.

The audience applauded, but my brother didn't think so He pushed forward and said to the Taoist priest, "What's the big deal? I will too. " Then my brother brought soap chips, water, white paper, turmeric and a writing brush. He first painted turmeric on white paper. Suddenly, the white paper turned yellow, and then he dissolved the soap slices in water. Here, my brother dipped his brush in soapy water, and then wrote four big characters on the white paper coated with turmeric. Immediately, four bright red characters "Breaking Superstition" appeared on the paper. The audience was full of praise. Seeing this, the Taoist priest ran away in despair.

It turns out. When the white paper coated with turmeric meets soapy water, it will react chemically and turn red. Taoist priests made "ghosts" with white paper in advance, soaked them in turmeric, and coated the sword that killed the ghosts with soapy water. When the Taoist priest met Jiang Huang with this sword, a chemical reaction took place, and in the dark, a scene of "ghost" being killed was produced.

On the way home, my brother said to me, "Fei Zixuan, learn more scientific knowledge in the future, and don't be confused by superstition!" " "I got the message and nodded.

Fan Siwen:

In today's era of knowledge economy, we hope that popular science newspapers and periodicals will not forget scientific sketches that can give people scientific interest, besides applying practical contents such as technology and life knowledge. This is of great benefit to cultivating people's love for science and promoting the construction of two civilizations.

The harmony between nature, society and human beings is the ideal peak of human beings. This is the meaning of making scientific knowledge intimate and touching, and appreciating the enlightenment of wisdom and the pleasure of seeking knowledge from it. Works with profound meanings can always inspire people's rich imagination and association, and readers will show a knowing smile between the lines or behind the cover: "I have read a lot of things that have not been written yet." This will often become the basis for further exploration.

Science needs both "understanding" and "feeling", some of which can be explained by language and some of which need to be understood. Most of the inventors' experiments and results are recorded in scientific literature, but there is no way of thinking to obtain such results. In the history of science, many people often work on the same research topic at the same time. Why did some of them succeed? Some failed? There is thought-provoking knowledge here, which is the key to broaden our thinking.

In front of mankind, there are too many complicated and difficult problems in modern times. With the increasing integration of various disciplines and the emergence of new disciplines, we need to broaden our thinking, which is the starting point for a better future.

⑦ Speaking of popular science, many people think that this is a job of popularizing natural science knowledge. In fact, popular science is not only the popularization of natural science, but also the popularization of social science.

The new issue of Qiushi magazine published an article by Xiao Dongbo, a professor at Ningbo University Law School: Popular science and social science cannot be ignored. The article holds that natural science and social science are two equally important knowledge systems in human society. Natural science is a science that human beings know and transform nature, and social science is a science that human beings know and transform society and promote social progress. They complement each other and jointly promote the development of human social civilization. Natural science needs popularization, so does social science.

The article points out that in short, social science must not be ignored in popular science. Relevant departments must treat social science as an important part of science popularization and should "emphasize science over literature". Popular science institutions at all levels should take the popularization of social science as an unshirkable responsibility, put it on the work schedule, and actively carry out various forms of social science popularization. The news media and publishing departments should also incorporate the popularization of social sciences into their work scope. The majority of social science workers should actively participate in the popularization of social science, disseminate social science knowledge to the people and carry forward the scientific spirit.

In the spring of 25 years ago, China Association for Science and Technology hosted the "National Symposium on Popular Science Creation". 1978 On May 23rd, there were 285 popular science writers from all over China on the banks of the Pujiang River. They are full of joy from the shackles of the "ten-year catastrophe" and talk about the expectations of the party and the needs of the people. With tears in their eyes, they picked up their pens again and vowed to fight for the prosperity of the motherland. "Spring of popular science creation" is coming! It's like a handful of golden seeds scattered on the land of one billion China. In just four years, more than 4,000 popular science books have been published. One hundred and twenty popular science periodicals came into being; More than 60 kinds of science and technology tabloids and newspaper science and technology supplements are circulated among the people; Popular science programs of 22 radio stations echoed on the motherland. China entered the second popular science climax. It is unforgettable to recall the grand occasion of that year.

After the Sino-Japanese War of 1894-1895, many people with lofty ideals believed that in order to save the Chinese nation, we must learn modern scientific knowledge from the West to eliminate those ancient evil thoughts. Because a person does not have a good understanding of the evolution of the universe and the evolution of living things, he will never have a correct view of the universe and life. While China advocated 1922, Liang Qichao gave a speech entitled "Scientific Spirit and Eastern and Western Cultures" at the annual meeting of the Chinese Science Society. He said, "What is the scientific spirit? My aunt explained in the broadest sense that systematic knowledge is called science, and the method that can teach people to acquire systematic knowledge is called scientific spirit. " He believes that scientific spirit can be explained by three meanings: the first is "seeking truth and knowledge"; The second layer is "seeking the true knowledge of the system"; The third layer is "true knowledge that can be taught". He believes: "All learning has an important element, which should be passed on to others. The reason why human culture can be established is because one person's knowledge can be passed on to most people and the knowledge of one generation can be passed on to the next generation. "

The first and second meanings of Liang Qichao's viewpoint seem to be similar to Ren Hongjuan's, and both believe that scientific spirit is an ideological basis for the occurrence and development of science. The third meaning is somewhat similar to the popularization of scientific knowledge that we advocate today.

At this point, it can be considered that it was in the 1980s that China scholars preached the scientific spirit and explained its connotation and importance through nearly a hundred years of running calls, which basically laid a theoretical foundation and attracted social attention. It is obviously not in line with the scientific spirit of "seeking truth from facts" to accuse the circle of popular science creation in the 1980s of neglecting to carry forward the "scientific spirit" or even putting forward wrong views.

In 1990s, the Party and government paid more attention to "carrying forward the scientific spirit".

Connotation of scientific spirit

Scientific spirit is all the creations and inventions of human beings.
