Speech on Science and Technology Changing Life 1 Science and technology is not only the law of the objective world and the ability and means for people to know and transform the world, but also the symbol of human civilization. The development of science and technology goes hand in hand with the progress of mankind. Since the 20th century, science and technology have advanced by leaps and bounds. Life science reveals the secrets of biological structure and heredity, enabling human beings to truly understand themselves. Space science makes it possible for human beings to travel to outer space and build their dreams of civilization. Information technology, computer technology and communication technology are leading the changes in many fields. All these have profoundly changed the living environment of mankind. Looking back on the course of human civilization, it was the light of science and technology that swept away the darkness of ignorance in human history, and it was the fire of science that ignited the ardent hope in human hearts. Science and technology support civilization and create the future.
Some people may say that technology is too far away from us. In fact, technology is all around us. With technology, we no longer need to light dim candles in the dark night; With science and technology, we no longer have to travel across mountains and rivers, and it is only a matter of time before we cross continents and oceans; With technology, we no longer have to drive 800 miles, just pick up the phone and press a number gently. We live and enjoy the achievements of science and technology every day. Life embodies the progress of science and technology everywhere.
Human beings benefit from science and technology, which originates from innovation. Innovation is not unattainable. When you solve a math problem with ecstasy, can you think of another solution? When you face the traditional water-saving countermeasures, can you think of better measures? Maybe a small chart design is our inspiration, or maybe transforming a noisy clothes rack is our future patented invention. This is how innovation is cultivated bit by bit. In science and technology, often a small innovation can give birth to a new great invention.
Students, as the backbone of the future construction of the motherland, we should not only pay attention to the development of science, but also establish a sense of innovation, closely combine the lofty ambition of rejuvenating the country through science and technology with our personal ideals, actively participate in various innovative practices, carry out scientific invention and creation activities, and experience the joy of growth and innovation in the upcoming science and technology festival. A journey of a thousand miles begins with a single step. Let's study hard, observe hard, think hard, practice hard and develop a pair of discerning eyes. Integrate science and technology into our ideals, decorate our lives with innovation, and work hard for the scientific and technological development of the country and the scientific and technological progress of mankind!
Speech 2 Technology changes life, teachers and students:
Good Morning, everyone!
The theme of my speech today is "Technology, Changing Life".
Science and technology always develop with the progress of human beings, and human life also changes with the progress of science and technology. Decades ago, our parents watched black and white TV, chose water far away, and cooked on the stove. Now, we are watching LCD TV. When we want to use water, we just need to turn on the tap gently. Just press the button when cooking.
Once upon a time, lighting at night was a very troublesome thing. Later, Edison invented the electric light to solve this problem. From then on, people can live at night like during the day. Once upon a time, it was almost impossible to communicate with foreign friends This has become a reality since the advent of the Internet. It can be said that the progress of science and technology has changed human life.
In the past, light-emitting diodes were used in light bulbs, which not only consumed electricity, but also had short life and low brightness. However, the current energy-saving lamps only need to consume15 of the power consumption of ordinary light bulbs on the premise of achieving the same light energy output, which can save a lot of lighting electricity and expenses. In the past, power generation needed a lot of coal, which not only wasted resources, but also polluted the environment. Nowadays, light energy, wind energy and water conservancy are used to generate electricity, which not only solves the waste of resources but also protects the environment. In the past, workers needed many processes to make a dress. Now, modern production methods not only shorten the production time, but also reduce the waste of manpower, and the clothes produced are more beautiful and generous. In the past, TV sets not only consumed electricity, but also had large volume and low definition. The current LCD TV is not only light, light, environmentally friendly and energy-saving, but also has higher image definition.
It can be seen that technology makes human life more convenient. Nowadays, people's lives are inseparable from science and technology, so we should make rational use and development of science and technology to make the world a better place. Our school is about to usher in the science and technology festival, and I hope all students can shine.
Thank you all.
Speech on changing life through science and technology 3 Dear teachers and students,
When it comes to science and technology, people may naturally think of artificial earth satellites, manned spacecraft, atomic bombs and other seemingly unreachable things, which often give people a feeling of being above. 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.
Science and technology always develop with the progress of human beings, and human life also changes with the progress of science and technology.
Developed technology occupies my whole modern happy life and is updated every day. Television, computer, refrigerator and mobile phone all appeared 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!
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 were 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!
Speech 4 Technology changes life, teachers and students:
Good afternoon everyone!
The theme of my speech today is "Technology, Changing Life".
Science and technology always develop with the progress of human beings, and human life also changes with the progress of science and technology. Forty years ago, when parents watched black-and-white TV, they had to go far away to fetch water, cook and light a fire on the stove, and travel a long way. Now, we are watching LCD TV. When we want to use water, we just need to turn on the tap gently. Just press the button when cooking and wave your hand when traveling, and you can get in a taxi and go where you want to go.
Lighting at night used to be a very troublesome thing. Later, Edison invented the electric light and solved this problem. From then on, people can live as usual at night. In the past, communicating with foreign friends was almost impossible. Since the advent of the Internet, it has become a reality. It can be said that the progress of science and technology has changed human life. 、
In the past, light-emitting diodes were used in light bulbs, which not only consumed electricity, but also had short life and low brightness. However, the current energy-saving lamps can save a lot of lighting energy and expenses only by consuming the power consumption of 1/5 to 1/4 of ordinary bulbs on the premise of achieving the same light energy output. In the past, power generation needed a lot of coal, which not only wasted resources, but also polluted the environment. Nowadays, light energy, wind energy and water conservancy are used to generate electricity, which not only solves the waste of resources but also protects the environment. It used to take many processes to make a dress, but now modern production methods are adopted, which not only shortens the production time, but also reduces the waste of manpower, and the clothes produced are more beautiful and generous. In the past, TV used picture tubes, which not only consumed electricity, but also had large volume and low definition. The current LCD TV is not only thin, light, environmentally friendly and energy-saving, but also has high image definition.
In the past, it took about three months to walk from Kunming to Beijing, but now it takes only three hours by plane. In the past, tuberculosis was an incurable disease, but now with the progress of medical technology, it has become a common infectious disease.
It can be seen that the progress of science and technology is inseparable from the development of mankind, and science and technology make human life more convenient. Nowadays, people's lives are inseparable from science and technology, so we should make rational use and development of science and technology to make the world a better place. So technology changes life, and life promotes the development of technology. In order to make our life better, please join me and work hard for the progress of mankind from today!
Speech on technology changing life 5 Dear teachers and students:
Good afternoon everyone! The topic of my speech today is "Technology, Changing Life". Science and technology always develop with the progress of human beings, and human life has undergone earth-shaking changes with the progress of science and technology.
40 years ago, our parents watched CRT black-and-white TV, which not only consumed a lot of electricity, but also had a large volume and low definition. Now I'm watching LCD TV, which is light, light, environmentally friendly and energy-saving, with high image definition. Tuberculosis used to be an incurable disease, but with the progress of medical technology, it has become a common infectious disease that can be cured. It used to take about three months to walk from Kunming to Beijing, but now it takes two or three hours by plane.
At first, we could only read Oracle Bone Inscriptions carved on tortoise shells and animal bones, but the number of tortoise shells and animal bones was limited. How can we describe the colorful real world? Time flies and the stars run. Today, our mobile phones, ipad, laptops and other small electronic products can record a lot of words.
However, technology has not stopped developing, and it won't be long before our e-books and laptops will become obsolete. "Holographic technology" is rapidly entering our lives. It is the general trend of the development of science and technology in the future, which makes our infinite reverie of a better life come true.
"Holographic technology" is based on the principle of interference and diffraction, which can reproduce the real touchable three-dimensional image of an object.
In March this year, Jane Zhang participated in the performance of "Champion of Chinese Language Rankings" in Chengdu. When the music started, Zhang appeared in the corner of the stage. Just as everyone was intoxicated with his singing, another Jane Zhang appeared in the center of the stage! The audience stood up and stared, unable to believe everything in front of them.
A scene. It turns out that the first appearance is 3D projection, and the center of the stage is the real brochure!
In the future, holographic technology will be more widely used, which will completely change our lives and make our lives more convenient and colorful.
For example, when we are far away from the desk, we only need to start a small 3D image transmitter, and a virtual screen computer will appear in front of us, so that you can process information on the screen facing the air.
Technology changes life, and life promotes the development of technology. In order to make our life better, please join me and work hard for the progress of mankind from today!
Speech on changing life through science and technology: Zheng xx, No.5 Middle School in xx District, 6 xx City.
Dear teachers and students:
Good Morning, everyone! Today, the theme of our national speech is "Science and technology change life, innovation makes the future".
What do you think when you are hit by an apple falling from a tree? Newton discovered gravity and revealed the law of celestial motion.
What do you think of when you see the jump cover on the stove? Watt invented the steam engine and realized people's dream of long-distance travel.
What do you think of when you live in a world lit by kerosene lamps and candles? Edison invented the electric lamp after experimenting with thousands of filament materials. Since then, light has been with us.
There are countless similar examples in the history of human development, which tell us that every progress of human life is full of scientific power, and every major achievement of contemporary social civilization is full of the light of science and technology. Science and technology are constantly changing our lives, and continuous innovation is achieving our future.
Perhaps many students will think that technology is too advanced and innovation is too far away from us. We can only enjoy technology, but not develop it. But in fact, technology is around us, technology comes from life, and innovation can change life.
An old man in the north found his little grandson prone on a cold desk to watch his homework in winter, so he embedded an electric heating wire in the desk, which can make the desk warm after being electrified. The grandfather later applied for a patent for the invention of this electric desk mat.
Also, when we use mechanical pencil, we often find that pencil lead will fall off. A student designed mechanical pencil upside down and invented a pencil that never stopped writing. Later, he applied for a patent and put it into production, which brought great convenience to the public.
On the campus of our No.5 Middle School, if you look closely, you will find that there are such a group of people who love science and dare to innovate.
Class 7 (12): With the help of his father, Wang Jiaxing made himself a solar cleaner. He said that the "cleaner" of sunshine is the number one "hero" in the family, and can wipe the fluorescent lamp spotless every time.
Class 8 (5): Wang xx, He xx and Jiang xx built a "straw structure" with a height of 1.83m with 50 straws, which is wonderful. Class 8 (10): Shi xx and Wang Cheng use 54 cards. Within 40 minutes, three cards with a height of 23cm are used to form a card combination structure. Students, guess how much weight they can bear? Exactly 50 kilograms. What is this? This is the magic, strength and beauty of physics.
Fruit or battery? Small body contains strange energy. With the help of Mr. copper and Mr. aluminum, the dance steps of chemical energy gradually faded away, leaving the figure of electric energy. When wonderful music plays, it is my most sincere blessing.
Have you ever thought that water can also be used as fuel? Ordinary water can't light a fire, of course, but when it blends with oil, the mystery of chemistry blooms!
Poetry-like language is the witness of our fifth middle school students learning chemistry, loving chemistry and using chemistry. Under the guidance of teacher Pei xx, four students, Wang xx, Ma xx, Xie xx and Xu xx, jointly produced Colorful Chemistry, which made us appreciate the beauty of chemistry.
In the fourth science festival of our school, there are often soaring water rockets, colorful geographical knowledge trees, unique biological teaching aid models, waste recycling and works of transforming old things on campus ... All the achievements shine with the light of science and technology and love for life. The students in No.5 Middle School are telling us to innovate and change our lives with practical actions, which shows that I am "happy to learn and talented" in No.5 Middle School.
Students, technology sometimes doesn't need high gold content, it is around us, as long as you observe it carefully, you can find the mystery. Keep a curiosity about the world, give your thoughts a free space and lay a solid foundation for the future. Science and technology push the world forward, and innovation makes our life more exciting.
My speech is over, thank you!
Speech on changing life through science and technology 7 Dear teachers and students,
Good afternoon everyone! The theme of my speech today is "Technology, Changing Life".
Students, when you watch cute cartoons, play fascinating computer games, get on the express train and answer overseas calls ... do you realize the power of technology? Do you realize that technology has changed the world and our lives, and technology is around us?
According to the brilliant tail of the comet, science and technology shuttled through the places just visited, from ancient times to the present. How many immortal great men are marching towards science and technology. Copernicus gambled on his life and showed Heliocentrism's trump card. Edison gave up his youth and did experiments day and night, just for "Iraq" tungsten wire. Finally, the electric light illuminates the whole world, everyone's heart, and technology illuminates our lives again. Forty years ago, when parents watched black-and-white TV, they had to go far away to fetch water, cook and light a fire on the stove, and travel a long way. Now, we are watching LCD TV. When we want to use water, we just need to turn on the tap gently. Just press the button when cooking and wave your hand when traveling, and you can get in a taxi and go where you want to go.
It is technology that gives us the convenience of life, and it is technology that gives us the continuation of life. As the saying goes, the body is the capital of the revolution, the body is great, and you can eat anything. If your ancestors got pneumonia or even a headache, it may be fatal. Looking at the current medical technology, almost all common diseases in life can be cured, prolonging people's life, allowing them to enjoy life, enjoy science and develop science. 2 1 century, dazzling achievements such as laser, nuclear technology, computer technology and gene mapping are making their own contributions with selfless spirit. They are all advocates of science and witnesses of science making life better. Believe it, science is a wonderful flower that never fades.
It can be seen that the progress of science and technology can not be separated from the development of human beings, and science and technology make human life better. Nowadays, people's lives are inseparable from science and technology, so we should make rational use of and develop science and technology to make the world a better place. So technology changes life, and life promotes the development of technology. In order to make our life better, please join me and work hard for human progress and scientific development from today!
