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. So how to write a composition about this activity? The following is a model essay I prepared for you about my scientific and technological activities with teenagers in 2022. Please refer to.

My essay on scientific and technological activities with teenagers (article 1) Everyone has his own science and technology museum, and the science and technology museum in my heart is like this. ...

Walking into the science and technology museum in my heart, there are many wonderful and interesting technologies in that tall building painted with colored paint. There is a robot in front of the science and technology museum, which specializes in invoicing and collecting money. Walking into the Science and Technology Museum, there are so many technologies in it that you are dazzled. You are greeted by a beautiful tour guide, who will serve you all the way and let you know the wonders of these technologies. In order to make people feel the wonder of science and technology, we paint the wall like the universe, so that people will feel like they are in the universe.

The first floor is China's invention. There is a huge rocket in it, but it's not real. It's a model rocket. There are the oldest great inventions in it. There are 65,438+000 inventions that have changed China and China, such as the first papermaking, the first compass, the first gunpowder, the first movable type printing, the first rope, the first drum ... all these inventions have changed China. Their appearance changed China's ranking in history, and they made our motherland strong and tenacious.

The second layer is foreign inventions, you know, the United States is the most advanced country, and their inventions are varied. In my science and technology museum, there are strange things invented in the United States, and the coffin periscope invented by George Willers, which means you can see the outside world in the coffin. I think this is specially made for people who are already dead! There is another invention that I think is the strangest. This is a toilet oxygen absorber invented by Williams Holmes. It is used in case of fire and gas poisoning, so that you can keep breathing with oxygen. In addition to these two things, there are other American inventions, such as ass-kicking fitness equipment, dust-proof clothing for dogs, cheese-flavored cigarettes and so on.

The third layer is some inventions made by ourselves. The third floor can invent things by itself. A big box is full of tools you need, and you can have whatever you want. This is mainly to test your impatience.

The fourth floor is a special place, which can also be called the experience area. The experience area is divided into two parts, the adult area and the children area. Someone asked: Why should it be divided into two areas? That's because some technologies can only be experienced by adults, and children are too young to experience that, so they should be divided into two experience areas. 100% is safe and will not bring harm to human body. You can go to the ground floor when you are tired!

The fifth floor is the sanitary area. At the end of each day, employees will come to pick up the cleaning equipment, and then start to clean the science and technology museum gently and quickly. And these inventions have to be cleaned up every week.

We arrived at the basement, which is the underground, which can be said to be the underground restaurant. There is cold wind blowing in summer and hot wind blowing in winter. This is really a flying fairy! We have all the food and drink, and we use fake grass beds. It feels like being in the forest!

I think you have almost visited the science and technology museum in my heart!

Today, I came to Zhaoqing Science and Technology Center Building for the first time. There is a lot of strange, interesting and scientific knowledge in it, which has always attracted me and made me never tire of reading.

"In order to illuminate the depths of the earth and see the rich mineral resources in the dark, the lamp of science is necessary!" Everything in the Science and Technology Center Building can be experienced by yourself. After entering the third floor, I was shocked. I feel like a sponge that has never seen the world, and the knowledge I have gained is negligible. Therefore, I must learn more knowledge and don't be a sponge that has never seen the world!

The first thing that attracted me was the "electromagnetic seesaw", which had two seats, on which Xiaoyi and I sat respectively. We don't have to work hard when we get up and down! Well done! Why is this happening? Let me tell you: that's because the same sex repels and the opposite sex attracts. There are many mysteries in science, and the only way for us to discover them is to study hard. A scientist also said: "Philosophy is the great mother of science!" "As long as there is the power of knowledge, everything can be invented!

The second thing that attracted me was the "Music Garden". There is a square thing. Curiosity brought me closer and closer. I handed my hand gently. "Mi Duo La ..." There are all kinds of voices, so I don't even have to touch them. Science also has interesting times! This thing makes me never tire of playing. When I grow up, I will also invent many things to benefit mankind! There are many things in the science and technology building: flower clocks, sloping huts and fire fighting games. ...

Unconsciously, the sky outside the window has gradually darkened. How time flies! Visiting the science and technology building made me understand that wisdom comes from life, there is still a lot of knowledge for me to learn and explore, and there are still many treasures waiting for me to dig in life for the benefit of all of us!

My essay on scientific and technological activities with teenagers (Chapter III) In modern society, science and technology have brought us countless conveniences. Television, computer, internet, mobile phone … these high-tech products have become the necessities of our life and work. Our survival and life are inseparable from them.

In the past, people used ancient envelopes and pens to express their thoughts and greetings to distant relatives or friends. It often took days or dozens of days to send letters to distant relatives or friends. This is not only slow, but also easy to lose letters; Now, all we need to do is turn on the computer, turn on the internet, sit in front of the computer, tap the keyboard a few times, click the mouse a few times, and send a letter to distant relatives and friends in a few seconds.

The Internet has connected all our regions, countries and even the whole earth into a global village, which has narrowed the distance between each of us and each country. In the past, the internet was only used by computers, but today, in the 2 1 century, mobile phones can also access the internet, and there are mobile qq…… ...

In the 1990s, almost everyone had a brick-like mobile phone in his hand, commonly known as "mobile phone".

"Mobile phone" is the "originator" of mobile phone. Gradually, with bb and PHS ... With the evolution of mobile phones, the functions on mobile phones are also very powerful. At first, the function of mobile phone was limited to making phone calls, but now, the function of mobile phone has been increasing day by day. Nowadays, mobile phones can not only make phone calls, but also connect broadband. You can enjoy surfing the Internet on your mobile phone, such as Angry Birds and Gold Miners. Some mobile phones also have gps navigators. No matter where you are, just open it and you will find the position you want.

Not only that, but now 3g mobile phones can also realize video chat. On such a mobile phone, if you want to call a friend. Start a video chat, you can see each other and see what they are doing. ...

Mobile phones have become an indispensable part of our lives. With mobile phones, our food, clothing, housing and transportation are all due to technology. Because science and technology are developing and society is developing, a country can be rich and strong. Because of science and technology, our living conditions will continue to improve and innovate; Because of science and technology, we can build a harmonious and stable society.

It all comes from technology. Technology makes life better.

I mentioned "science and technology" in the essay on scientific and technological activities of teenagers (article 4). Perhaps the first thing you think of is the cutting-edge technologies such as rocket ascending into the sky, submarine entering the water, suspended train, Shenzhou-8 and Tiangong-1. In fact, technology is not far away from us: when the hot summer comes, we can enjoy the cool in a comfortable air-conditioned room; When we are hungry, my mother cooks a delicious meal for us with an induction cooker, a rice cooker and a microwave oven. When we are too busy studying or working to take care of a lot of clothes to change, the washing machine solves the problem for us … Look, technology is around us.

Going home from school on Friday, sitting in front of the TV, listening to pop songs and watching Chinese and foreign news anecdotes broadened my horizons, enriched my knowledge and made me happy. It's really "knowing what's going on in the world without leaving home."

When visiting relatives and friends, electric cars, motorcycles and even more and more popular cars have shown infinite charm. It won't be long before we can get together with our relatives and friends under the breeze.

When we go out to travel, or get on the train and fly in the mountains, we can see the beauty of nature at a glance; Or fly in the vast sky, accompanied by blue sky and white clouds; Even sitting on the maglev train, you can feel the comfort of lightning speed. Technology is really amazing, which brings a lot of convenience to people.

The emergence of telephones and mobile phones has made us bid farewell to the era of flying pigeons delivering books and enhanced the communication between people. The popularization and use of computers not only brings people a way to get rich, solves many problems in people's lives, but also eliminates the pain of missing distant relatives. This summer vacation, my family bought a computer. Through the video, grandma met her father who worked in Guangzhou. This made grandma very happy, changed her old malaise, and she was happy all day, and never nagged her father to come back to chat with her again.

Even in our rural schools, computers and multimedia devices are used in classrooms, which greatly improves our interest in learning.

……

Watt invented the steam engine, Edison invented the incandescent lamp, Franklin invented the lightning rod, and Bell invented the telephone ... It is the development of science and technology that leads the continuous progress of human society. Our great ancestors, after numerous experiments, have created many miracles for us. Nowadays, the development of science and technology is in full swing, and great achievements have been made in military, medical, aviation and daily life. Cloning technology and nanotechnology are no longer strangers.

We live in the age of science and technology, and we grow up in the life of science and technology. As the founders of the new century, we should set up lofty aspirations and bravely climb the peak of science and technology. Looking forward to the future, the motherland will be a great landscape, and in the near future, our life will be better by science and technology.

Technology is not only around me, but also in my heart, in my swaying dream.

My Essay on Scientific and Technological Activities with Teenagers (Part 5) When I saw my classmates boarding the platform one by one because of their scientific and technological works, I couldn't help but sigh: "If only I were!" So I have a technological dream in my heart! Although this dream is difficult to realize, I will try my best to make my dream come true. Of course, my dream is to be an editor-in-chief of technical design drawings.

Design drawing, a familiar name, contains hard work and wisdom. Because the designers have tried their best to design a design drawing. How do they want to design here? What is the function of this design? Can China make progress in science and technology? These are all things that designers must consider. What I want to design is a small technology that can make infusion patients feel comfortable. Because I was very upset when I saw those patients infusion, my hands could not read and my hands could not move, so what I wanted to do would be limited. If it moves, something will happen. So I want to design a design for patients. So I made a list. One: think about the general appearance. Two: draw it. Three: Revise the drawings to see if they are reasonable. Four: Imagine the approximate result and see if it can be assembled.

After my careful study, I finally came to the conclusion that this idea is not impossible, but can be realized. Now let me introduce this technology! This technology is very simple, with only three parts. The first part is: a plastic thread, connected to the bag full of medicine, will not fall off. The second part is: an iron ring that can be loosened and tightened on the finger at will like a watchband. When the iron ring is removed after infusion, a micro sensor on it will start, and the adhesive tape originally stuck on it will pass through, and a small pusher will push the adhesive tape down. At the moment when the iron ring is removed, the adhesive tape will be pressed down and tightly adhered to the eye of the needle. The third part is: the needle, the needle may be very common, but this needle is connected to the plastic pipe. There is a flexible needle at the lower part of the tube. Just put the iron ring on your hand and fix it with tape, and then the needle will go in, so that the medicine can flow out of the tube and enter the body, so that the disease can be cured faster. However, this method can reduce a lot of pain for patients when inserting needles.

This little technology is simple to say, but it is not simple to design. It takes a lot of energy and time to design a rough plan, and others need to go further to succeed. Therefore, no matter what technology you do, you must persist in doing one thing in order to succeed. This will make you feel more fulfilled.

My Essay on Science and Technology Activities with Teenagers (Part VI) 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!

My Essay on Scientific and Technological Activities with Teenagers (Chapter 7) 2 1 The coming of the century has brought people a surprise-advanced science and technology. In recent years, "technology" is getting higher and higher, and people's lives have gradually become more convenient and affluent with technology.

Developed technology occupies my whole modern happy life and is updated every day. Television, computers, refrigerators, mobile phones ... all came out in this golden age.

Computers are the most brilliant, dazzling and popular among these science and technology stars. He is becoming more and more advanced and popular, even primary school students can't live without him. It has countless uses. You can use it to play games when you are bored, which brings joy to people. The computer has changed from black and white to color. The computer can help me look up information, practice typing and make slides, just like my best friend in my life. The teacher assigns a composition every week, and almost every time I have no class to write. I used to be in a hurry, or I couldn't find satisfactory information after tossing and turning, which was extremely troublesome. But it's different now. You can easily find the answer by typing the required classes on the computer. Computer is an indispensable thing for students to study. Computers can express sincere wishes to people during festivals. E-mail during the Spring Festival can enhance the friendship and relationship between friends, and promote family relations and happy family life. Pictures on the Internet can send good wishes to people.

There used to be only a dozen TV stations, but now there are hundreds of TV stations, which really makes people dumbfounded! The TV is not as thick as it used to be. Now there is a night crystal TV, which is not troublesome to use. There will be 3D TV in the future, so you can enjoy that happy time without going to the scene!

After I bought food before, I became moldy after a few days. Since I have a refrigerator, the food can be kept fresh and the nutrition of the food has not been lost. A family can live a happy and beautiful life.

If there are no mobile phones, people will still be in trouble. With mobile phones, the distance between people is closer and people's friends are increasing day by day.

It can be said that technology has made my life happy and convenient!

I asked who doesn't know what an "Olympic Games" is in "Essay on Scientific and Technological Activities with Teenagers" (Chapter 8)? The Olympic Games are famous all over the world, and the old people and children are full of enthusiasm for it.

When Beijing succeeded in bidding for the Olympic Games, people all over the country were very excited. The sky was filled with colorful fireworks and the air was boiling. It can be seen that the Olympic Games has been deeply rooted in the hearts of the people, and everyone's attention to it has reached the boiling point. From that night on, the shadow of the Olympic Games was deeply imprinted in my mind.

Nowadays, people's enthusiasm seems to have "calmed down". Our excitement is gone. Is the Olympics "out of date"? But don't forget that since 2000, these eight years have given us time to prepare. Eight years passed in such a hurry, and time passed as fast as running water. How can we not seize the opportunity? How can we abandon the crazy heart?

We can't trample on the opportunities that we and our citizens are striving for!

It was a sunny morning, and I was in a good mood on Friday. I go to school at a brisk pace. Suddenly a violent cough cut off my heartbeat, that is, a lot of mucus secreted by trachea and bronchial mucosa, plus saliva, landed on the dirty road. It caught my attention by no means because of novelty. It should be said that I finally realized that along the way, I have seen more than a hundred scenes. People in formal clothes, old people going out for a walk, workers on the construction site ... all have roughly the same behavior, which appears in my only eyes over and over again, even most of my classmates. I can't help feeling a little excited. It's not prejudice against modern education, but I feel sorry for the students' years of study. This is a waste of social efforts. ...

It can be said that people lack awareness of environmental protection, but I just want to ask coldly: "Do you remember the Olympic Games that were bid for in 2000?" Please don't forget, please remember "Green Beijing, Green Olympics", please don't defile its green!

For the 2008 Olympic Games, the country spent a lot of money that we can't imagine, on the one hand, greening, on the other hand, construction. For developing China, these eight years are by no means rich. What can we do? "Don't hesitate to enjoy flowers, don't hesitate to enjoy the moon." Let's continue to treat the Olympics with enthusiasm and support the development of the motherland!

I believe people's enthusiasm is not only at the beginning of the Olympic Games. Six years ago, I found a burning heart from everyone's crazy joy, and there was an image in my young mind that the Olympic Games was an immortal "sunshine". I was influenced, and I totally love it, because it is so "bright" in everyone's heart. Now I write this article with the same heart: I believe that the Olympic Games in everyone's mind are like sunshine, and I believe that the Olympic Games like sunshine will remain the same. I have a little bump at the moment, but I will not die in the future!

My essay on scientific and technological activities with teenagers (Chapter 9) usually likes to watch popular science programs. Today's program is also black technology.

Black technology is more powerful, new technologies, new products and so on. An expert in the development of safe unlocking is developing voice-activated locks, that is, unlocking with our own voice and setting passwords. If you forget the password, just say a few words.

There must be many people who are skeptical about this matter. After all, technology is so advanced now that it is easy to imitate a person's voice. The reporters interviewed are also skeptical, because experts are also in the testing stage, and people from all walks of life are welcome to challenge.

At that time, the reporter came up with a way to take out his mobile phone and record what he said, and then unlock the expert's mobile phone. I thought it would work. After all, it is a person's voice, and the content is the same, but what I didn't expect was that the unlocking failed.

The reporter thought that the quality of mobile phone recording was not very good, so he re-recorded it with professional recording equipment and the result was still the same. Unlocking failed. Experts say that you can recognize mobile phones when recording, and they also say a lot of technical terms.

Experts also announced the open competition to the public and sent recordings to the contestants. Participants can imitate this sound, and if successful, they can get a prize of 80 thousand yuan. The reporter also participated, and the reporter found the audio expert with this recording.

The sound expert will synthesize the sound, and also played a synthetic voice of Ma Yun to the reporter, which can be said to be any specified content, but it took only about half an hour to synthesize Ma Yun's voice. One minute recording is too short, which is a problem. The reporter went to find network security again, but it still didn't succeed.

The publicly released competition results have also come out. Those who don't succeed seem quite safe and successful. I believe we can use voice lock in the future.
