Scientific and technological innovation composition

What do you think of science fiction innovation? Let's enjoy the essay on scientific and technological innovation with me!

Model essay on scientific and technological innovation 1:? Technology empowerment? Science and technology innovation competition

On Friday, we decorated the classroom beautifully. The blackboard seems to be painted with heavy makeup. What does it say? Technology empowerment? Four big characters, surrounded by all kinds of fantasy paintings, such as grotesque pistols and so on. You must ask: What is this? To tell you the truth, we held it to welcome the inspection team. Innovation and display of scientific and technological works? What about activities!

The activity is about to begin. We all stood up as soon as the inspection team came in. After sitting down, the host announced the official start of the activity, and we clapped our hands very nervously and excitedly.

When the host asked:? Who wants to show his work first? The students' interest seemed to reach a climax, and they all raised their hands in unison. I was no exception, but the first one didn't ask me, but asked Arus to introduce his works first. Arus made a small electric drill, but his idea was really strange. He put the pen tip on a small toy with a motor he used to play with and made a small electric drill, which is convenient for punching and can be carried around. Secondly, Tian Qiushi's intelligent anti-theft lock has not yet become a reality, but the idea is very strange and novel, which deserves further study.

Next, Liu Jiaqi and Chi Xinyi introduced their works, which inspired me a lot.

? Who wants to introduce me next? I raised my hands as usual. Oh, thank God, I finally found me. I calmly walked onto the podium and talked endlessly.

? I made a rubbing lamp. I made friction lamps because I was inspired by movies. Every old bicycle in the movie has a rubbing lamp. I made a friction lamp according to the principle of friction lamp, but my friction lamp is not bright enough for the time being.

This time? Innovation and display of scientific and technological works? It not only broadens my horizons, but also increases my knowledge. I also learned a lot of common sense that can be applied to life. I hope the school can carry out more similar activities.

Model essay 2 on scientific and technological innovation: low-carbon life starts with me

Someone asked? What is a low-carbon life? Low-carbon life can be understood as: reducing carbon dioxide emissions is a low-energy, low-consumption and low-cost lifestyle. Originally, I didn't know what a low-carbon life was, but after the teacher's introduction, I gradually understood.

Volcano eruption, unprecedented tsunami, global earthquake, great changes in the earth's crust and sharp rise in sea level are all scenes in the movie 20 12. Although all this is fiction, I am still frightened after reading it. It is often seen on TV and books that the top ten environmental problems in the world today include climate warming, ozone layer destruction, biodiversity reduction, acid rain spread, forest decline, land desertification, air pollution, water pollution, marine pollution and solid waste pollution. If these environmental problems are not solved in time, those scenes in the movie 20 12 will be staged in reality in the next few centuries.

Low-carbon life is the only way to save the world. In fact, low-carbon life is to go back to the past. When there were no cars, televisions and computers, life at that time was a low-carbon life. At that time, it was the safest time for mankind. Although cars, computers, televisions and refrigerators have brought us a lot of convenience, they are also the culprit in releasing carbon dioxide.

On the road, cars are always flowing, and each car will emit a lot of carbon dioxide, making a lot of noise; Now almost every household has a lot of electrical appliances, such as computers and televisions, which need electricity. Electricity uses some natural energy sources, which will be used up one day, and some energy sources will also emit a lot of carbon dioxide when generating electricity.

In fact, cars should be used less now, and bicycles can be used. As long as it's not too far, you can ride a bike. Bicycles are the most environmentally friendly means of transportation. It doesn't need any energy, just your feet. Nowadays, young people can't live without computers almost every day and write with them. In fact, you can write on draft paper. But you can't mess with the draft paper, you have to write line by line, and you can't scribble. And the rest of the blank space can also be used as endless topics, which can be used for drawing and calculating.

My mother used to turn on the tap when washing clothes, but how many times did she pass by me? Education? Since then, my mother has developed a good habit of saving water. Did she? Shine on you is better than blue? Yes, she collects water for washing clothes and uses it to flush the toilet. There are many plants at home. Every morning when I get up, I bump into a breath of fresh air. Let me have a good mood every day. When you go shopping, try to use your own environmental protection bag instead of the disposable bag in the supermarket.

Do not use disposable chopsticks and disposable lunch boxes; Do not use disposable plastic bags; Reduce food waste; Turn off the lights, turn off the tap. Using handkerchiefs instead of paper towels should be a good habit we primary school students must develop. Now there is less and less green on the earth, and we primary school students should plant all kinds of trees. As long as everyone plants a tree, there will be more and more green on the earth. Let's live together for our ancestors? Make a little contribution to the earth!

Water is the source of life, electricity can't be wasted, trees can't be cut down, and many kinds of trees are needed. Environmental protection is very important. I hope more people will protect the environment and join the low-carbon life in the future, so as to restore the original beauty of the earth and make the living environment of mankind better! Save every drop of water and every kilowatt hour; If you can go to walking to school and work, you don't have to take the bus; Try to travel by bus and drive less fuel cars. Starting from the small things around us, choosing a low-carbon life and being a small environmental guardian is actually very simple. Please remember, whenever and wherever possible, try to reduce the energy consumed in life and work and rest. Who are you? Low carbon people? .

Science and technology innovation model essay 3: low-carbon life starts from me

On a sunny morning, I stood in the field, breathing fresh air, and felt everything was so beautiful and fresh. With the fresh air, my day's low-carbon life began.

The teacher once told us that a low-carbon life is to reduce carbon dioxide emissions, that is, a low-energy and low-consumption life. Simply put, a low-carbon life is to return to nature and carry out activities between man and nature. What a complicated and simple philosophy of life! It is complicated because my little brain can't understand such profound physical and chemical knowledge. In fact, it was only put forward and practiced by the ancients. Harmony between man and nature? Philosophy of existence. In this way, I went to water the flowers with a watering can. Last night, when my mother cooked, the water was Taomi water, which not only saved water, but also brought water and nutrition to the flowers. The faint fragrance, fresh morning light and warm sunshine tell me that it takes effort and careful maintenance to integrate into the natural life. Really? Be careful? It's not necessarily difficult. It is to pay attention to the details in daily life and start from small things. I advocate low-carbon life everywhere from the news and the internet, and regard it as a lifestyle and attitude. I gradually understand how important low carbon is to our life. So I'm going to establish a new habit for myself, such as mopping the floor with water after washing my face every day, trying not to turn on the lights where I can see them, not using disposable chopsticks, and caring for every grass and tree in nature.

Green environment is indispensable in our life. If there is no green around us; If our world is not green, then we will not be able to live on the lovely earth! I believe that a low-carbon life should start with each of us. As long as Qi Xin and Qi Xin work together and stick to a low-carbon life, the earth will be better.

Model essay on scientific and technological innovation 4:

Everyone is familiar with the word technology. Computers and televisions are gifts of technology. Since Watt invented the steam engine, the whole world has entered the era of science and technology. Since Edison invented the electric light, we have left the darkness and worshipped technology more; Newton discovered the law of gravity because an apple fell from the tree, which made science and technology take a big step forward.

Technology is fun, which contains at least several meanings. First, science and technology itself and the natural laws governing the universe are full of charm; Secondly, the process of exploring science and technology and revealing the laws of nature is also very interesting. Third, once science and life collide, the relationship between science and technology and human society, whether positive or negative, is also very interesting.

Technology is everywhere, and technology makes human beings extremely proud!

How important technology is to us, if one day, without electricity, people will continue to live in darkness; Without gas and oil, wouldn't people want to eat raw things or drill wood to make a fire and continue to pull carts with raw animals? Without mobile phones and computers, do people still use flying pigeons to pass books?

From this perspective, we can't live without the contribution of science and technology all the time. I believe that everyone around us is always exploring the development of science and technology in their own way. The submission says that although I am naughty, I really experienced the taste of technology: I put some baking soda powder in the quilt and then added white vinegar. At this time? Volcanic eruption? Yes! Suddenly, white vinegar emerged.

With the rapid development of science and technology, science not only serves the cutting-edge technology, but also penetrates into our daily life more and more, which requires us to love and learn science in our youth. I participated in the provincial science and technology innovation and invention competition and won the second prize. He also participated in the municipal science and technology innovation and invention competition and won the third prize. These achievements are inseparable from the hard work of teachers. Participating in science and technology competitions and reading science and technology books have made me understand a lot. Precise robots, cars without fuel, virtual football matches, high-tech information transmission, and so on, vivid and interesting phenomena have aroused my desire to explore science more and more. Each of us should study science, spread civilization and create a new life while enjoying life. Nowadays, the technology products are updated faster and faster, and video TV, computer surfing and pacemakers are not new. From the vacuum cleaner invented by 190 1 to artificial earth satellites and manned spacecraft, science and technology have shown great power in different fields. With the popularization of electronic industry and communication technology, and the wide application of nanotechnology and superconducting materials, bioengineered foods such as space green peppers and artificial steaks will appear on your table in the near future. Studying science and technology is not only to become a scientist and adapt to life, but more importantly, to become the master of the new century, to undertake the new century and to make contributions to national construction and human civilization.

Since the founding of New China, China has made rapid progress in science and technology, such as synthesizing insulin, replanting severed hands, hybrid rice, exploding atomic bombs and hydrogen bombs, and launching satellites and spaceships. These remarkable scientific and technological achievements have greatly shortened the gap between China and advanced countries and injected vitality into China's modernization drive. Grandpa Deng Xiaoping said? Science and technology are the primary productive forces? Indeed, science has given wings to the take-off of our motherland. President Mao Zedong once told young people that the world is yours and ours, but in the final analysis, the world is yours. This sentence is full of the ardent expectations of our elders. If the elders of the 20th century built the motherland with hard work, then we should shoulder the burden of the new century with knowledge and science.
