Dear teachers and students:
Hello everyone!
For thousands of years, from horse-drawn carriages to cars, trains and planes; From kerosene lamps to incandescent lamps, neon lights and energy-saving lamps; From the ends of the earth to close at hand, video chat and mouse know everything about the world. ..... History has been changing and technology has been developing. From primitive life to learning to cook food, from relying on nature to thriving, from unarmed to metallurgical smelting, it is the result of scientific and technological innovation! Only innovative science can make tomorrow's life better!
Einstein challenged authority, boldly innovated, and finally overthrew Newton's second law, which was authoritative in physics. Yuan Longping, a famous agronomist in China, has finally cultivated a high-yield rice variety known as' Oriental magic rice' after more than 30 years of efforts. There is also a bacteriologist Fleming, who persevered, studied hard and explored constantly, and finally found penicillin that benefited mankind; Throughout the ages, looking back and looking at the four great inventions, they are all the best; Look at the astronomical calendar and marvel; Look at Zhaozhou Arch Bridge, which is beautifully designed; A glimpse of the oriental masterpiece compendium of materia medica: look at the value of pi, seven decimal places; Overlooking the Silk Road and developing the economy; Blue and white, famous in the world.
From primitive society, to slave society, to feudal autocratic society, and finally to the primary stage of socialism, our goals and society, step by step, are masterpieces of our Chinese sons and daughters, because this is our task.
Think about every successful scientist, which one does not have lofty ideals? Which one has no persistent pursuit? It is because of their lofty ideals and persistent pursuit spirit that their dreams have finally come true.
Although technology has changed our lives, animals are also born to die. The turbidity of the air makes animals unable to survive, and the harsh environment makes most animals on the verge of extinction.
Innovation is closely related to dreams, and technology is closely related to life. Bold innovation to realize dreams, innovative technology to change life!

Dear teachers and students:
When it comes to science and technology, people may first naturally think of artificial earth satellites, manned spacecraft, atomic bombs and other things that seem out of reach. She often gives people a feeling of being above others. In fact, with the rapid development of science and technology, science not only serves the cutting-edge science and technology, but also permeates our daily life more and more. Technology and life have long been inseparable, and technology is everywhere.
During the summer vacation, I participated in the summer camp for young journalists in Beijing. During the days when we were away from our parents, the teacher asked us to inform our parents about our activities every day. When staying in a hotel in Beijing, it is extremely difficult to find a public telephone because people are different and can't walk around casually. IC phone cards prepared before leaving are often lost. At this time, I will especially envy those "group friends" who have mobile phones, and I will deeply feel the convenience that mobile phones bring to people.
In China Science and Technology Museum, we saw the old hand-cranked telephone that can only be seen in TV and old movies, and we also learned how inconvenient it is for people to contact in the primitive way in the era when there is no telephone. Every time I see the footage of party member risking his life to send messages and losing contact signals in the battle, I can't help thinking, if I had a mobile phone, wouldn't I have avoided these unnecessary sacrifices? From time to time, I will be more aware of the power of science. Science has not only changed the whole world, but also changed our lives. Science is all around us.
A few years ago, people called mobile phones "mobile phones" and pagers "BB machines". Making and owning them is something to show off. It seems that this is a symbol of money and status, and it is synonymous with "big money" and "fashion". Today, with the rapid development of science, the telephone has spread to thousands of households. From white-collar workers in companies to ordinary vegetable farmers and even people who collect waste products, their dependence on it is increasing day by day. It occupies an increasingly important position and becomes an important means of communication in people's life and work. It is obvious to all, from fixed telephone to mobile phone, from single communication tool to color screen and video mobile phone, it makes people's life colorful. Seeing this, you can't help sighing at the rapid development of science and technology.
As a new generation of middle school students, while enjoying our new life, we should set up lofty ideals and aspirations, love science, learn science well and create a new life from childhood. Every student here probably has the same dream. When they grow up, they want to be scientists, produce more scientific research results and contribute to the construction of the motherland and human civilization. This is a lofty goal. In fact, we learn scientific knowledge not only to become scientists, but also to adapt to the ever-changing new life.
Therefore, from now on, we should cultivate a strong interest in learning, study hard scientific and technological knowledge, learn all kinds of cultural classes well, read more popular science books and actively participate in various scientific and technological activities. There is no limit to human wisdom. No matter the Challenger explosion in the United States or the global computer virus upgrade, it will never stop the scientific and technological progress of mankind. "Knowledge is power", Bacon's famous saying inspired many people who are eager for knowledge. Now, let's use it to motivate ourselves, be a new generation that loves science, and write more brilliant poems for the future of our motherland!
Thank you all.
The fire is burning for a hundred generations and the lights are shining for a thousand years. Students, let's hold high the flame of civilization and cross the century. Create a beautiful and exquisite life of mankind with the magic and greatness of science and technology. Let China's star of science and technology reflect the splendid culture of 5,000 years, and let the fire of Chinese civilization shine among the nations of the world.
My speech is over, thank you!

Dear teachers and students:
Hello everyone!
The Science and Technology Museum is the music box where the sound of science plays and the hall where the light of science burns. With the development of the new era, people's understanding of science and technology is getting deeper and deeper, and the "Science and Technology Museum" has become a place for people to understand science. When science and technology develop more and more advanced, what will the future science and technology museum look like?
In my mind, the future science and technology museum is gorgeous. It is rich and colorful, and all scientific and technological facilities are very advanced. Let's take a look at this place-Shiro Island. There is a track with a transparent viewing room on it. Its room is light blue, with a water-red rotating ring. You can see many colorful dinosaurs and plants when you sit in it. They are made up of many moving particles. The viewing room runs along the track and can interact with dinosaurs at any time. Because dinosaurs are controlled by a moving particle system, they won't hurt people. Even if you pull the tail of Tyrannosaurus Rex, it won't get angry. People innovate. When the enemy attacks, they use active particle dragons to attack the enemy. The dinosaurs controlled by the system were good at fighting and were very brave, and soon won.
In my opinion, the future science and technology museum is great. Its shell is nano-glass, which will not break, and it is full of scientific and technological facilities for everyone to watch and practice. Every two or three days, the staff will invite people to the glass cabin near the shell, turn on the oxygen supply, press the button, and the owner of the back cabin will fly out of the earth at the speed of light and explore the vast universe without worrying about getting lost in the gorgeous universe of the Milky Way. After time, the four glass pillars at the bottom of the Science and Technology Museum will be based on the signals sent by the earth. People have encountered many unsolved mysteries in the universe before exploring and using this new science and technology museum.
In my mind, the future science and technology museum is unexpected. Now people can reach their destination quickly. Although there are trains, cars and planes, time is still not fast. Time flies, people in the future invented "liquid wings"-these wings are transparent, precisely liquid, but this special liquid will not flow everywhere. As long as you put on special clothes, put the "liquid wing" into two small grooves on your back and kick your legs, the bones in your body will be as light as birds, you can fly freely over the science and technology museum and control your own speed! Soon, this kind of clothes and "liquid wings" flooded into the market, and anyone could fly freely without restraint. People are convenient, and the use of this kind of high-tech goods greatly shortens the communication time and is faster.
There is a saying that "technology changes life". No matter the current science and technology museum or the future science and technology museum, we will never lose three elements, that is, innovation, exploration and convenience. The light of science will never go out!

Dear teachers and classmates: Good morning, everyone! I'm Li Siyang from Class Two, Grade Four. Today, the topic of my speech under the national flag is: Technology is with us.
Where the spring breeze blows, there will always be a vibrant place; Autumn wind always leaves the joy of harvest on the road; What has been moistened by the rain and dew is the fragrance of birds and flowers. So, class, let's think about it. What will it be when technology is saturated?
From ancient wooden drills to today's electronic lighting; From ancient hiking to today's space travel; From the supercomputer in the 1940s to the handheld computers sweeping the world today, all scientists have devoted their lives, and they have injected infinite positive energy into technology and innovation with their knowledge and wisdom. Qian Xuesen made great contributions to the development of rocket and missile technology in China. Deng Jiaxian, known as the "father of two bombs", was developed by China's nuclear weapons, and Yuan Longping is known as the "father of hybrid rice". Their success naturally stems from science and technology, which has left China's footprint.
Today, we are sitting in the spacious and bright classroom, listening to the teachers' humorous lectures on scientific knowledge and wandering in the ocean of science. Those scientific phenomena worth exploring, unexpected scientific experiments, and scientific inventions with hands and brains will inspire our enthusiasm for falling in love with science. As long as we have a curiosity to explore and ask questions, a spirit of being diligent in studying and not afraid of difficulties, and a meticulous and serious scientific attitude, I believe all the bits and pieces will accumulate. Students, from now on, let's be a caring person who loves science, polish our childish but wise eyes and discover the technology around us. In the future, you or I will definitely dress up our more colorful life with the skills we learned today!

Hello, students and teachers present! I am preparing for Class One. Today, I have the honor to give a speech entitled "Technology and the Future". I am proud, but a little uneasy.
In recent years, we have seen the rapid development of science and technology in our great motherland, which makes me feel extremely proud. I am a China native.
I remember a long time ago, there was almost only one purpose of mobile phones, that is, making phone calls. But a few years ago, mobile phones have changed a lot, not only in appearance, but also in many uses. They can be used to take photos, have meetings, surf the Internet, send short messages and so on, which makes our life more convenient and makes me more aware of the power of technology. However, I am just a fledgling student.
But I want to think about technology and the future from the perspective of a student.
From the dream of genetic engineering to the promise of nanotechnology to ensure that you don't have to wash clothes; From the warmth of artificial intelligence "giving you a lovely robot dog" to the spectacle of transgenic technology "making mice grow human ears"
New technologies are constantly being born, and every discovery of new technologies will make people ecstatic, because these new technologies are gradually improving our lives and making us know ourselves better.
In the near future, China completed the whole genome sequencing of SARS virus for the first time. At present, SARS is recognized as a harmful disease in the world, but why can't other countries be the first, while our country has? Quite simply, this shows that our country is not backward, nor worse than others. Looking back on our motherland's past, from a country that has just started reform and opening up to a big country with a high level of science and technology, our motherland has experienced many ups and downs, many difficulties and bumps, but our motherland has survived, because our motherland firmly believes that science and technology can not only change fate, but also change the future.
For our generation, the general feeling given to the society is a strong sense of competition and sufficient motivation to learn.
Popular science knowledge is the focus of our attention, Einstein, Hawking and Bill Gates are the stars in our minds, and computer science, modern physics and chemical kinetics are influencing us all the time.
We have understood the importance and universality of science and technology.
Although the prospect of technology creating a new life is fascinating and fascinating.
But in the final analysis, it depends on the concerted efforts of all of you, Qi Xin.
As the backbone of the future construction of the motherland, the burden on our generation of young people is really not light, and new opportunities are always accompanied by risks and challenges. However, we will not give up easily. We swear to our predecessors with our youth that we will never live up to their hopes.
Looking back on the course of civilization, it is the light of science and technology that sweeps away the darkness of human ignorance, and it is the fire of science that ignites the burning hope in human hearts; Science and technology support civilization, science and technology create the future, and the future is in our hands.
Let's become explorers of knowledge, let's roam on unknown roads, and let's use our creativity to make the world we live in a better place.

Good morning, class:
I am XXX.
Today, the topic of my speech under the national flag is science and technology, the power of knowledge.
Human beings benefit from technology, and technology benefits from innovation.
This week, we ushered in the annual Science and Technology Week.
From Monday's science and technology competition to Thursday's visit, we will deeply realize that the word "technological invention" is not so far away, but really around us: maybe a small faucet is our inspiration, maybe a modified box is an invention that we will apply for a patent in the future, maybe a mirror, a clothes rack ... Who knows, life is impermanent, maybe there will be future scientists among us. ...
As a middle school student, besides studying hard, you should also learn to innovate.
Human beings benefit from science and technology, which benefits from innovation, and innovation is the soul of science and technology.
In modern times, whether in the street or after meals, people always talk about "gene technology", from the dream of "making people live to a thousand years old" through genetic engineering; The promise of nanotechnology to "ensure that you don't have to wash clothes"; From the warmth of artificial intelligence "giving you a lovely robot dog" to the spectacle of transgenic technology "making mice grow human ears"
This genetic technology contains many technologies waiting for our innovation and discovery.
As a Fengfeng person, you can't achieve harmonious Fengfeng, ecological Fengfeng and green Fengfeng by yourself.
However, it is necessary to publicize that "everyone collects firewood and the flame is high."
Let's work together to create a good living environment.
Let China know about Fengfeng through science and technology, and let the world know that there is a harmonious, ecological and green Fengfeng. These new technologies are gradually improving our lives.
From a country that has just started reform and opening up to a big country with a high level of science and technology, our motherland has experienced many ups and downs and experienced many difficulties and bumps, but our motherland has survived, because our motherland firmly believes that science and technology can not only change fate, but also change the future.
Our gizmos may be rough ... our papers may be immature ... Compared with floating beds and nanotechnology, their existence may seem too small and naive ... but no one will deny them ... because today, they may become the next generation products of science and technology and fly into the homes of ordinary people! Today's era is an era that needs innovation. Students, let's not live up to the good times now. Please hurry up and study hard, find opportunities to develop yourself, lay a solid foundation for future development, and make our due contribution to the rejuvenation of our nation and the prosperity of our country.
Thank you!

Hello teachers and students present!
Today, I feel very honored to give a speech here on the future of technological creation. Not long ago, the annual Science and Technology Festival opened in Shanghai Science and Technology Museum, which made me realize that in recent years, the science and technology of our great motherland is developing rapidly. I remember a long time ago, there was almost only one purpose of mobile phones, that is, making phone calls. However, in the past few years, great changes have taken place in mobile phones, not only in appearance, but also in many uses. Mobile phones can be used to take photos, have meetings, surf the Internet and so on, which makes our life more convenient and makes me more aware of the power of technology. However, I am just a fledgling student and have limited knowledge of the word "technology". I can't explain the mystery of science and technology with some profound theories, but I am willing to think about science and technology and the future from the perspective of a novice student.
From the dream that genetic engineering can make people live to 1000 years old, to the promise that nanotechnology can make you wear clothes that don't need washing; From artificial intelligence to the warmth of a cute robot dog, to the wonder that transgenic technology makes mice grow human ears, new technologies are constantly being born, and every discovery of new technologies will make people ecstatic. When SARS became a globally recognized harmful disease, we in China were the first to complete the whole genome sequencing of SARS virus, which made China's international status increase day by day, and made our motherland more convinced that science and technology can change destiny and create the future.
For us who are always busy studying, popular science knowledge has become the focus of our attention. Einstein, Hawking and Bill Gates are the stars in our hearts, and computer science, modern physics and chemical kinetics are influencing us all the time. We are more and more aware of the importance and universality of science and technology, so there are often scientific and technological inventions in our campus.
The prospect of science and technology creating a new life is fascinating and fascinating. Looking back on the course of civilization, it is the light of science and technology that illuminates the darkness of human ignorance and the fire of science that ignites the hope in human mind; It is science and technology that supports civilization and creates the future, and the future is in our hands. Let us become explorers of knowledge, explore on unknown roads, and make the world we live in a better place with creativity.

Dear teachers and students:
Hello everyone! Last time, I was lucky enough to participate in the 30th Guangzhou Youth Science and Technology Innovation Competition, and I saw many creative works, which deeply touched me. It is also related to the fact that we are in a changing era, and many useful things need new ideas to create. Therefore, the topic I want to discuss with you today is: innovation!
Let me give you an example to make you feel the ubiquity and importance of innovative thinking. More than 300 years ago, an Austrian doctor treated a patient with chest disease. Because the stethoscope and X-ray fluoroscopy were not invented at that time, the doctor could not find out where the disease was, and the patient died. Later, after autopsy, it was learned that the deceased's chest was inflamed and suppurated, and there was a lot of water in the chest. As a result, the doctor blamed himself and decided to study the method of judging pleural effusion, but he couldn't figure it out for a long time. It happened that the doctor's father was a shrewd wine merchant. His father can not only distinguish the quality of wine, but also estimate the amount of alcohol in the bucket without opening it. Inspired by his father's knocking on the bucket, the doctor thinks that a person's chest is not similar to a bucket. Since the father can judge how much wine is in the bucket by knocking on it, if there is water in a person's chest, the sound of knocking on the bucket must be different from that of a normal person. After that, when the doctor examines the patient's chest, he will knock with his hand. By comparing the chest tapping sounds of many patients and normal people, he can finally diagnose whether the chest is sick from the tapping sounds of several parts. This diagnostic method is now called "percussion" in medicine. In recent years, this "percussion" method has been further developed. 186 1 year, a French male doctor, Lake, was in a dilemma when he was treating a woman with heart disease. Just as he was in a dilemma, it suddenly occurred to him that he was taking part in children's games. The children are in a round tree. At the other end, you can hear the scraping sound with your ears close to the log, and it is still very clear. Inspired by this, he asked someone to take a piece of paper, tightly roll it into a cylinder, put one end on a woman's heart and the other end on his ear. Sure enough, he heard the patient's heart rate sound, even better than listening to the patient's chest directly with his ears. Later, according to this principle, he changed the roll paper into a small log and changed it into a rubber tube now. This shows how great innovative thinking is, and it can create things that benefit people.
Today, China is striving to build an innovative country and vigorously develop science and technology. As teenagers in the 2 1 century, we should actively cultivate our innovative thinking, improve our practical ability and make contributions to the great cause of our motherland. So, how can we cultivate innovative thinking? First of all, knowledge is the premise of innovative thinking. Without solid knowledge accumulation, even with innovative ideas, it is impossible to turn ideas into solutions to problems. Newton has a classic saying: I see farther because I stand on the shoulders of giants. The shoulders of giants are the precipitation of predecessors' knowledge, so the first step to cultivate innovative thinking is to accumulate knowledge. Second, practical experience is the fundamental basis of innovative thinking. Knowledge is constantly innovating and developing in the process of theory, practice, theory and practice. Therefore, in our study and life, we should pay attention to observing details, accumulate practical experience and lay a solid foundation for innovative thinking. Finally, divergent thinking is the basic method of innovative thinking. When we can't solve the problem directly, we can try to use reverse thinking, reverse thinking, lateral thinking, analogy thinking and associative thinking to propose solutions from different directions. I believe that if we strive to achieve the above points, innovative thinking will be gradually cultivated.
In today's world, the competition between countries is very fierce. The focus of its competition is science and technology, and the core of scientific and technological competition is the competition of talents, and the standard for measuring talents is their innovative ability and talent. Therefore, the core of creating an innovative country and building a prosperous country is to cultivate innovative talents. Teenagers' wisdom makes the country wise, teenagers' wealth makes the country rich, teenagers' strength makes the country strong, and teenagers' independence makes the country independent. As teenagers of this era, as innovative talents trained by the country, we should study hard and practice actively, carve ourselves into talents that meet the requirements of the times and make contributions to the great cause of the motherland!
Thank you!
Science and Technology Festival Speech 350 words 10
Human beings grow up in social development, and human thinking is constantly trying in development. Things are organic combinations, and biological or abiotic things can change people's views on them. Using these to create what people need is called technology. Using it on the basis of science and technology is called innovation. Innovation is diversified, and if it is used well, it will certainly benefit mankind.
People also have two sides, and their ability to observe and judge things is instantaneous. For example, Newton's law of universal gravitation is obvious to ordinary people. No one thought, no one analyzed. Before Newton appeared, people thought that "theism" was "benefiting" people. This foolish idea has no scientific basis. However, Newton happened to find apples falling from the sky, and thought that one of them had some kind of "power", and this power came from outside the earth. At that time, no one dared to imagine these so-called things outside the earth. It was Newton who discovered this falling body that led to the so-called technology. There are many such things, for example, radar is invented by using the echo of bats, and ultrasound is invented by using the sound of dolphins.
The charm of science and technology exists not only in some living objects, but also in inanimate things. People can choose technology. If we innovate simple things and use them in useful places, we can create many new things, such as the invention of lasers, electric lights and computers. We all know Bill Gates. Without his invention, the computers we know would only be typing, computers and these simple things. These may be unknown so far, so they have changed from single to multiple.
However, due to human innovation in things, some things are harmful to the native earth, and the increase of carbon dioxide is harmful to the environment. Therefore, we should pay attention to protecting the environment while inventing many new things, otherwise the near future will be like the "20 12 doomsday" mentioned in the book, and this result is not what anyone wants.
With the rapid development of 2 1 century, we must understand the beauty, charm, frontier and beautiful things brought by science and technology, but it is not enough to rely solely on science and technology. These so-called technologies are all created by human beings themselves. While new things are constantly replacing old things, we must understand what is good. Using good things in useful ways will certainly develop and bring good and positive things to people, so we believe in the power of science and technology.
