Science and technology and life composition

Since the industrial revolution, science and technology in various countries have been developing continuously, and people's lives have been getting better and better. At first, people entered the age of steam engine, and then, people entered the age of electricity. Nowadays, household appliances can be seen everywhere. ...

What would our life be like without the participation of science and technology? People won't dress beautifully as they do now; People won't build high-rise buildings ... On the contrary, if there is no technology involved in our life, then our life will be as boring as that of the ape era!

Now, our country is getting stronger and stronger, and science and technology are also developing day by day. Various new scientific and technological products have changed from generation to generation, and people's lives have become rich and colorful. After countless experiments, Edison finally invented the electric light, so that people don't have to live at night like fluorescent lamps, and they can work normally at night like during the day ... Since Yuan Longping, the "father of rice", cultivated super rice by farmers, people no longer worry about food shortage ... Since the Wright brothers invented the airplane, people don't have to take a boat, take a car, let alone walk to far places, so they can. In short, technology has changed everything! Without the development of science and technology, everything today is impossible!

Technology influences the present, and technology creates the future!

Technology, as its name implies, is science and technology. Everyone should be familiar with science and technology, because it is used and served by us and it is closely related to our lives. It not only brings us spiritual pleasure, but also physical comfort. In this rapidly developing society, science and technology represent a kind of spirit as well as a kind of strength. It represents an innovation and a civilization. It is an important symbol to measure a country's comprehensive national strength, and science and technology occupy an important position in any field.

Science and technology are widely used, including military, biological and aerospace. Technology has been integrated into life and enriched it. In the street, at home, in the classroom and in the shop, technology has brought convenience to people. It can be said that human beings created science and technology, and science and technology also created human beings. Human beings and technology are interdependent. Our food, clothing, housing and transportation are inseparable from technology. Let me take you into the wonderful life of science and technology.

Clothes make the man, and everyone needs clothes to dress himself. Take a closer look at the clothes we wear. Acrylic, silk and pure cotton ... are slim, warm and healthy ... countless, which bring us warmth, comfort, health and happiness. These clothes can't be made without technology. Let's say warm clothes can make you feel warm. In the cold winter, we don't have to wear thick down jackets and sweaters, but only a light and soft warm clothes can make us feel warm. You see, isn't this the convenience brought by technology?

Let's see what we eat. Now, we should pay attention to everything we eat, that is health! With the progress of society and the development of human beings, people's concept of food has also changed, not only pursuing delicious food, but also demanding healthy and nutritious food. Nowadays, many people eat high-tech foods, such as protein powder, calcium tablets and dietary fiber. , are studied by scientific and technological personnel. Today, we talk about a high-tech food: vegetable juice drink. Vegetables are an important source of vitamins and minerals and the guarantee of life and health. In terms of nutrition and health care, vegetables can provide comprehensive nutrition and prevent or even treat nutritional deficiency. However, because the taste of vegetables is not accepted by most people, scientists and technicians have improved vegetables and made a delicious vegetable juice drink, which has become an ideal future drink.

Next, let's look at the most common material for building houses-cement. Cement is a brownish gray powder made of limestone and clay. When it is used, it becomes hard and abnormal when mixed with water. In recent years, with the development of new technology, functional cement has been continuously developed. There are many kinds of high-tech cement, such as glass cement, light cement, rubber cement, sugar water cement and color-changing cement. They all have their own characteristics and are the crystallization of science and technology. Today I'm going to introduce you to a magical cement: color-changing cement. This kind of cement is not only an ideal building material, but also can be used to forecast the weather. Also known as "meteorological cement", it is blue when the weather is dry. Once wet, it turns purple; If it rains, it will become a bright rose after absorbing water. It changed color because cobalt dioxide was added to the cement. Look, isn't it amazing? In fact, this is also the surprise and convenience brought by technology.

Speaking of cement, let's talk about cars. The car is a convenient and important means of transportation. Whether traveling or going to work, it is convenient to have a car. Looking back at the history of automobile development,1On July 3rd, 956, the first medium-sized truck named "Jiefang" was born in China, ending the history that China could not make a car. Later, Dongfeng brand domestic cars were produced; The first 2.2-ton military off-road vehicle; First adopt 60 dump trucks; The first coach and the first red flag car, etc. Today, Honda, Mercedes-Benz, BMW ... these are the crystallization of science and technology, releasing the charm of science and technology. It is the development of science and technology that has brought us today's convenient cars. It can be seen that science and technology have made great contributions to us, and everything we have today cannot be separated from science and technology.

Science and technology have played an important role in food, clothing, housing and transportation, facilitating and benefiting mankind.

In the rapidly developing 2 1 century, technology is not mysterious. It is hidden by your side. As long as you observe it carefully, you can also invent your own technology. Perhaps the small technology you invented, after being modified and perfected by experts, has become a veritable scientific and technological product, and can also make great contributions to the future society and mankind.

Students, science and technology is a magical and great cause, which brings infinite joy and convenience to our lives, allowing us to understand, discover and create science and technology. I believe that technology comes from life, and life cannot be separated from technology. Let's use our wise eyes to discover technology!

Primary school edition:

Love and apply science to make our life better.

I used to think that scientific creation was only for the old experts, and it had nothing to do with us middle school students. I don't think so since the school launched the activity of "Love Science, Love Life". It turns out that some people with great inventions have loved science since childhood and made painstaking efforts for the development of science and human civilization. Newton often began to make small machines and inventions when he was in primary school. Gauss discovered the binomial theorem at the age of 1 1 and invented the method of making 17 polygons with compasses and straightedge at the age of 18. Since ancient times, teenagers have produced talents. Science is not mysterious. Science is around us middle school students, depending on whether we use our brains or not.

The development of modern science and technology has opened up a vast world for our teenagers to love and apply science since childhood. There is a computer in our school. Computer is a bridge and tool to science. I like computers. I can draw a blueprint of the future world in my mind and paint my beautiful dream in my computer. I would like to use computers to climb the peak of science with middle school students all over the country.

The teacher said that today's era is an era of scientific competition. Who is strong among countries and who is capable among people depends on who is leading in science and technology. The older generation of scientists promoted the development of science and human civilization with their outstanding contributions. We teenagers are the future of our motherland. We should follow their example, love science since childhood, pay attention to civilization, study hard, strive to improve ideological and moral quality and scientific and cultural quality, constantly improve scientific practice ability and innovation ability, be a scientific creative person and serve the motherland.

Science makes life better.

-The story of Archimedes

No one has made such a great contribution to the progress of mankind except the great Newton and the great Einstein. Even Newton and Einstein used to draw wisdom and inspiration from him. He is "the ideal embodiment of the combination of theoretical genius and experimental genius", and he is the scientist Archimedes whom I admire most.

Today, I will tell you the story of Archimedes.

Archimedes was born in a small village near Syracuse, Greece. He was born in a noble family, and his family is very rich. Archimedes's father was an astronomer and mathematician, knowledgeable and humble. Influenced by his family, Archimedes became interested in mathematics, astronomy, especially ancient Greek geometry. Archimedes was smart and studious from an early age, so he stood out among his peers from an early age.

Once, King Hennon asked a goldsmith to make a pure gold crown for him. After the completion, the king suspected that the craftsman had mixed silver into the crown, but the crown was as heavy as the pure gold originally given to the goldsmith. Did the craftsman play tricks? This question not only stumped the king, but also made the ministers look at each other. Later, the king gave it to Archimedes. Archimedes thought hard about many methods, but all failed. One day, he went to the bathhouse to take a bath. Sitting in the bathtub, he saw the water overflowing and felt his body being gently pulled up. He suddenly realized that he jumped out of the bathtub and went straight to the palace without clothes on. It turns out that if the crown is put into water, the amount of water discharged is not equal to the same weight of gold, and it must be mixed with other metals. This is the famous law of buoyancy, that is, an object immersed in a liquid is subjected to upward buoyancy, and its size is equal to the weight of the liquid discharged by the object. Later, this law was named Archimedes principle. This has benefited our future generations a lot.

In addition, Archimedes also obtained the area and volume of parabola bow, helix and circle, as well as the volume of ellipsoid, paraboloid and other complex geometric bodies, discovered the lever principle and obtained the solution of cubic equation. His achievements in science have left a glorious page in the long history.

After learning Archimedes' story, I benefited a lot. The science we usually emphasize is spiritual. Archimedes taught me that science must be practical. With the spirit of practice, science is truly meaningful and can add luster to our lives, while the "spiritual" science with lip service is illusory. To give a simple example, people think that the Great Wall can be seen with naked eyes in space, but when Shenzhou 5 flew into the sky, this was proved to be wrong. This confirms the old saying: "Practice is the only criterion for testing truth."

Science and technology and life

Science and technology are everywhere, which makes us feel extremely proud. Our food, clothing, housing and transportation are inseparable from the contribution of science and technology.

Inventions and creations in the 20th century have brought endless changes to mankind. Zipper: seamless; Washing machine: liberating the labor force; Vitamins: make the tree of life evergreen; Rice cooker: uncooked rice is cooked into cooked rice; Air conditioning: There are four seasons like spring here; Cixian floating train: a train that can "fly"; Neon lamp: sleepless pearl ...

Ah! Now the technology is really developed! Even our school has endless science and technology.

In a science class, Miss Wang gave us a lesson about "electricity and magnetism". Teacher Wang told us: "The electricity in life comes from 1820. In an experiment, Danish scientist Oster accidentally put the electrified wire close to the compass and found that electric energy produces magnetism. Because of this discovery, it opened the door for human beings to use electric energy on a large scale. " In the following time, we did another experiment. We first prepare a compass, a battery and a wire, then straighten the wire, remove the plastic at both ends of the wire to expose the copper core, and then connect the copper core at both ends of the wire to the positive and negative poles of the battery. Then we put the wire near the small compass. At this time, we observed that when the wire just approached the compass, the compass suddenly turned. After disconnecting the current, the compass is as quiet as a child who has just been taught. The teacher told us that this is evidence that electricity produces magnetism. At that time, we witnessed the mystery and interest of technology together.

Science and technology support civilization and create the future. The future is in our hands. Let's become knowledge explorers, roam on unknown roads, and make the world we live in a better place with unlimited creativity!
