How to write a composition to avoid stepping on thunder? The following is the essay for the Science and Technology Festival organized by me for you. Welcome to reading. I hope you will like it.

Essay for Science and Technology Festival 1 Hundred Scenery Map of Xiantao

My hometown has a name that makes foodies drool, and that is "Xiantao". Xiantao is a picturesque city; Xiantao is a city with many delicious foods; Xiantao is an open and enlightened city, enjoying the glory of Shang Jin.

Old landscape map of Mianyang

I often listen to the stories of the older generation when they were young. At that time, the name of the old family was still "Mianyang". "There are dirt roads, red brick roofs, ponds and fields everywhere." The pictures of backward mountain villages on TV are like the old scenery of Xiantao. It's good to have a bike at home, not to mention a car. It is conceivable that the living conditions were difficult at that time and it was inconvenient to travel.

I once asked my grandparents, "Xiantao was so poor at that time. What is your study and life like? " The elder replied, "At that time, few people could read. They all teach primary schools in junior high schools, junior high schools in senior high schools and universities. That is a very small number! " "When we were your age, we started washing clothes and cooking and taking care of our younger brothers and sisters." "Older than you, thirteen or fourteen-year-old children go out to work to make money. You are very happy now. " I compared the childhood of the older generation with ours, and then I realized that they often said, "I don't know if I am blessed!" " "

New urban landscape map

Only by comparing the past can we find the beauty of life now. The dirt road in the past has become the asphalt road now. In the past, tall buildings stood on the fields. Just last year, infrared water spray sensors were installed on the sidewalks at every traffic light intersection. As long as someone runs a red light and forcibly crosses the road, it will automatically spray water when it is scanned by infrared rays, reminding him to obey the traffic rules and not to pass; There is also an automatic "traffic police", which will remind you of your safety on the roadside according to the traffic lights. Needless to say, new energy buses are energy-saving, have no exhaust emissions, have low noise when driving, stop or start smoothly, and feel better when riding. Inadvertently, the development of science and technology has been integrated into our lives, making life more comfortable!

City vision map

The change of science and technology has brought a lot of convenience to people's lives, and people's happiness index has also been greatly improved. However, with the development of science and technology, because of the uncontrolled exploitation of resources and unreasonable use of chemicals, sewage can not be properly treated, and the balance of natural ecology has been seriously damaged. I hope I can change the ecological environment through science and technology, and I hope my hometown can be better planned and developed to make people's lives better! Against the background of blue sky and white clouds, the air is fresh, surrounded by green plants, people and cars are separated on the wide road, people are busy in an orderly way, and their faces are filled with happy smiles.

In order to get these changes, we must start from ourselves, care for the environment and obey the traffic rules; Learn to classify garbage and make rational use of recyclable resources. Let's study hard, become useful materials, contribute to the construction of our hometown, and look forward to the bright future of Xiantao!

Since the invention of the steam engine, mankind has entered the industrial age; Since the invention of the electric light bulb, human beings have lived a bright life; Since the development of modern network, human beings have used computers, mobile phones and televisions. ...

Ancient times and now, because of technology, people's lives are completely different!

Many years ago, people bought heavy goods and went to the road to barter. And a few decades ago, with a canteen and a supermarket, you could buy things for a little money. Now you can buy online on your mobile phone, and you can buy things with your fingers.

In primitive times, people had to walk to where they wanted to go. Gradually, people have simple means of transportation, such as boats and sedan chairs. Nowadays, many novel means of transportation are emerging ... cars, trains, high-speed trains, airplanes and other means of transportation have become commonplace.

Science and technology benefit mankind and broaden our horizons.

In primitive times, human beings wanted to know: what is beyond the mountain? Slowly, knowing what is on the other side of the mountain, I want to know: what is on the other side of the sea? Now, we already know what is beyond the mountain. What's beyond the sea? I also have a certain understanding of the universe full of yearning for the ancients!

From sedan chairs to cars to high-speed rail, there are changes everywhere; From barter to currency to online shopping, there are changes everywhere; From sundials to clocks and watches to electronic clocks, there are changes everywhere. ...

Einstein said: "Science is endless, it is an eternal mystery." In the future, we will live up to expectations. As long as there is technology, the future will be better.

Needless to say, spaceships in outer space and deep-sea detectors can create the future only through lifestyle changes and technological changes!

Science and Technology Festival Essay 3 86 years ago, Xiantao was just a backward small county. 1986, when it retreated to the county seat, the town was transformed into a new city with a vibrant name "Xiantao".

You can see the great changes in Xiantao just from the traffic. When mom and dad are around, they have to walk around. If you want to go to a distant town or city, you must take a "bus"-there were no buses at that time. But what about leaving?

Of course, cycling is also a good way, but not many people had bicycles at that time. Later, everyone got on their bikes and hit the road. It is not convenient to pile bicycles sideways or even upside down. After all, there are people left, and the problem remains.

It's different now. A series of well-served "SUV" and "4S" stores have sprung up. The traffic lights on the left and right sides of the sidewalk repeat the warm words of no passage or safe passage. At the crossroads, the conspicuous electronic screen scrolls with propaganda articles such as traffic without trivial matters, and it is happiness to get home safely. The avenue is full of traffic, but it is orderly.

In the past, people could only go to the neighboring Xiantao city by train. Every time you go, you should go one or two hours in advance. How to play well if you are in a bad spirit?

But now Xiantao people don't have this trouble. People can also go to other places in their hometown by train. Xiantao Station has been opened, not to mention Xiantao West Station. When a stranger asks if there is a railway station in Xiantao, we can also proudly answer: "We do, there are several!" " "

Not only that, Xiantao Airport also appeared in front of people. I was lucky enough to visit it!

Once Mianyang, now Xiantao, traffic has undergone earth-shaking changes. In the planning of Hubei Province, Xiantao will soon become a regional central city!

Science and technology festival essay 4 has arrived at the annual science and technology festival again. Today, the weather is fine, which is a special good day for our teachers and students. Science and technology festival is a great tradition of our school, and it is also a grand meeting of science and technology activities. During this week, the school will tailor different activities and competitions for students of all grades. Senior students in senior high schools have high-end activities and various modes. Our activities are simple, interesting and wonderful.

It is said that the spirit of the festival lies in its atmosphere. The Science and Technology Festival adds a layer of science and technology to our whole school outside Hangzhou. Walking in school, you can often see the experimental models of seniors and sisters. In the teaching building, students often laugh in various competitions, and every student is influenced by technology.

Our activities include paper airplanes and shooting, paper airplanes floating and bamboo dragonflies, which make the class lively. The students studied several folding methods of paper planes, so in their spare time, paper planes flew all over the sky. In addition, in the corridor, some students tried to fly bamboo dragonflies, or dragged a board to carefully "push" the paper plane forward. I took part in the competition between bamboo dragonfly and suspended plane.

The event was really exciting when the game was going on. The bamboo dragonfly competition is held at noon on Wednesday. Although the sun is shining, the front of the school information center is still full of people. Wang Zichen and I are in a group. The venue is near the square. In this range, we compare flight time and flight distance. At that time, I felt that flying was not too far, only about two meters. But Chen Shuaihua, a classmate in our class, flew more than six meters. Although the results are still unknown, I believe our class must be very good.

The most exciting game is the paper plane shooting and levitation on Thursday afternoon. The venue is in the school gymnasium, which is full of students and teachers from Grade One and Grade Two. It is very lively. Compared with the other seven students, I dropped out of school. Everyone is practicing before the game time. As the saying goes, "when you get cold feet, sharpen your knife and don't miss the woodcutter." . At the beginning of the game, we showed our strength. Everyone takes turns to "transport" the plane to the destination in an orderly manner, striving for health while making steady progress. For me, except for being the first to fly out of bounds, I still played normally and felt good about myself later. In the end, our class won the second prize, and the paper plane shooting won the first prize.

The Science and Technology Festival ended successfully, and we gained a lot. In the competition and practice, we not only gained knowledge, but also exercised the team's cooperation ability. Outside Hangzhou, there are many activities at ordinary times. These colorful activities let us learn a lot, enrich our lives, enrich our hearts and teach us how to find a balance between relaxation and study. I love my beautiful school and the annual science and technology festival!

Writing five compositions for the Science and Technology Festival is no stranger to everyone. People can see it when they drink water, brush their teeth, wash their faces, make soup and wash clothes. However, water is actually mysterious. Do you want to know its mystery? Then listen to me one by one.

First, let's learn about water quality. Tap water actually contains many minerals, and the quality of water is closely related to its PH value. Let's do a little experiment. I have prepared two glasses of water, one is tap water and the other is pure water. At this time, two glasses of water are colorless and tasteless. I dropped two drops of PH reagent into the tap water and gently shook the cup, and the tap water immediately turned light blue. Compared with the PH color chart, the PH value is 8.0. I used the same method to test pure water, the color was a little dark blue, and the displayed PH value was about 8.5-8.7. It can be seen that these two kinds of water are alkaline. Then, I put a conductive pen in these two kinds of water, and the red light on the tip of the pen indicates that both kinds of water contain minerals. Next, I dropped two drops of residual chlorine in two kinds of water, and the comparison showed that both of them contained 0. 1 residual chlorine. Experiments show that these two kinds of water quality are beneficial to human body.

The secret of water doesn't stop there. Water can also take on various crystals. What water sees and hears is the water crystal formed by different characters, just as people feel when they see and hear these characters. When it sees words like love and gratitude, water crystals are neat and beautiful; Seeing the words that hurt people and are vicious, the crystals formed by water are terrible, and sometimes they can't form crystals. Perhaps, there is only gratitude and love in nature!

Water is also closely related to the weather. Our common fog, rain, frost and snow are all phenomena formed by water in climate change.

Everything in the world comes from water. Without water, life will disappear. This shows how amazing water is! However, at present, most of the water sources in the world have been destroyed and polluted, and they are not as pure and clean as before. The war in the world now is for oil, and the war in the future may be for pure water. Therefore, we should all cherish water!

Science and technology festival essay1February, the long-lost snowflakes come lazily, decorating the earth into a world wrapped in silver; 1February, after a long separation, Mei Dan confided her heart in a brocade dress, which filled the air with a sweet and refreshing smell ...1February, imagination inserted wings for science and technology, innovation flowed in the first science and technology festival held by our school, and the campus was filled with sparks of wisdom collision!

In the egg-to-earth competition, the egg had a friendly and close contact with the earth, and the creativity made the egg and the earth embrace each other deeply. In the process of designing the device, the students took it seriously and overcame the difficulties. Although their hands are covered with glue, the joy of creation is irreplaceable. Although the process is accompanied by disputes, the collision of ideas shines brightly; Although I didn't enter the final, the fun of participating in the competition has become an indelible treasure in my memory!

Eggs hit the earth, let them dance like flowers, let thoughts follow the falling trajectory!

Draw a proofreading picture and let the brush flow on the silk paper. It feels very comfortable!

Make a metal tree, let the materials combine into gorgeous colors and gush out!

At the Science and Technology Festival, we also saw various exhibits. "passive water" makes us admire the designer's whimsy; "Probability Estimation" allows us to appreciate the infinite interest in mathematics; "Spine rolling" makes us experience the impact of visual illusion ... When we linger in front of one exquisite exhibit after another, we feel surprised, excited and full of hope. ...

Science and technology are constantly developing, and the pace of science will never stop like time, which requires us to keep exploring.

"Laughing at the wind and cloud, a big country despises weapons" is a portrayal of Mr. Ye Duzheng, the winner of the highest national science and technology award. An elder, in his scientific career, kept exploring and vowed to "let foreigners join us". He is "the founder of his heyday and still a pioneer at the age of 70." Now that we are in the prime of life, we should also have such pioneering spirit and stand on the shoulders of giants. We should not be afraid to explore and advance bravely!

I have heard something that has always moved me. It was a college student who said in his speech, "We study English hard today in order to study Chinese hard all over the world in the future." Now, for us, so is technology! I want to say: today we are trying to explore in the scientific world in order to let our dreams fly and make our life better!

"Wise men enjoy water, benevolent people live long, explorers expand their territory, and they were once young and frivolous. Now they are in full bloom, they are diligent in thinking, dreaming of science and technology, dreaming of lofty aspirations, dreaming of infinite possibilities, green children, opening their lives with wisdom and decorating the world with science and technology! "

In the science and technology festival, we learned to think, innovate and cooperate. In the ocean of science, anything is possible. Let us interpret the connotation with actions, and one day, we will see the power of throwing stones to ask for directions!

Science and technology festival essay 7 time flies, the sun and the moon fly like a shuttle. How time flies! It's already 2 1 10. China's science and technology have also developed rapidly. Through the continuous efforts, experiments and improvements of scientists, the "Cosmic Life Museum" has been created, and people's desire to live in the universe has been realized.

Now let me introduce this great invention to you!

The living room in the universe is round. In order to be more conspicuous in the universe and avoid accidents, scientists designed him as Liang Cheng Silver. It is mainly divided into two floors: the lower floor is between me and the storage room, the lower floor is the main living room, bedroom and cockpit, and the hatch is on the upper floor.

You should be curious, why doesn't the universe life museum have a kitchen? Let me give you an answer. We use special soil to plant the seeds of fruits and vegetables brought from the earth on the moon. After the care of the gardener robot, we produce big and delicious organic fruits and vegetables. Your mobile phone will be bound to the system of the Space Life Museum. As long as you click on the "daily food" voice on your mobile phone and say the name of the dish you want to eat, the "side dish" system will immediately inform the space porter to transport fresh vegetables from the moon and then cook for you. In three minutes, you can enjoy delicious food.

When you want to have a rest, click "Sleep in Peace" and the Cosmic Life Museum will start the sleep mode. All the objects in the living room of the universe are static, the walls are soundproof, and beautiful lullabies will be played for you ... Don't worry that there is no oxygen in the living room of the universe, scientists have solved it, and the gases from different planets are the oxygen we need after synthesis! The living room in the universe is equipped with air traffic control, so it is easy to input oxygen into the room, plant some vegetation and there will be fresh oxygen!

Cosmic Life Museum is not only convenient and comfortable to live in, but also can drive like a car, taking everyone to travel in space.

Start the "spaceship" in the cockpit and fly it, and you can travel. But pay attention to the space signal lamp! Cosmic Life Museum can cruise automatically, just press the big yellow button, click the blue button when determining the direction, replace the living room wall with glass, and lie on the sofa to enjoy the beautiful planet. How refreshing!

The Universe Life Museum has many functions. Come and experience it!

How great and incredible the power of science and technology is, let's create even greater inventions together!

Science and Technology Festival Essay 8 Who traces numbers with branches on the distant horizon of ancient civilization? In the endless movement of objects, who rules nature with laws? Who turned the stone into gold by magic in the plain wilderness?

Who lit up the night and conquered the sky?

It is the lamp of science and technology, leading the rapid changes in the world and guiding mankind from ancient times to the future.

Flood year, cycle after cycle. Walking on the banks of green water, we can still hear the voice of ancient human wisdom echoing in the air. Perhaps from the beginning of the creation of heaven and earth, the lamp of science and technology has been lit!

When the first fire came from the sound of chopping wood, when the first axe was born from the collision, I seemed to hear the rustle of technological life. Time, like a blink of an eye, has gone through the vicissitudes of time. The looming secrets in the Egyptian pyramids, in which subtle numerical operations are like the brilliance of spring; The wonders of China's four great inventions, the brilliance of papermaking and the brilliance of compass are like the scenic wonders at the source of rivers.

Igniting the lamp of science and technology is the playing of the song of life and the strong sound of the pace of the times.

Science and technology have promoted reality and accelerated the pace of the times.

From poets singing and drinking wine, reciting lime collected from mountains, to towering buildings and huge factories; From the ancient quadrangles in Beijing to today's villas and buildings; From the forgotten "gray-green ocean" in history books to the enduring trend of clothing and accessories ... The development of science and technology makes changes everywhere, which will keep Yun Fan high for life.

Science and technology is not only an instinct for knowledge, but also a product of deep thinking.

Hua once said: "Independent thinking ability is an essential talent for scientific research and invention. Any important scientific creation and invention in history cannot be separated from the inventor's independent and in-depth solution to the problem. " We teenagers should learn to think independently and innovate technology. "The history of knowledge is like a great polyphonic music, in which the voices of all ethnic groups ring in turn", which is Goethe's poetic language. He told us that the starlight of knowledge will fall and converge into a beautiful waterfall, from which a nation will roar with endless steps.

Let's light the lamp of science and technology!

We are still young and in the early stages of life. We are the most unique charm of the four seasons, and we have charming scenery. We are optimistic, confident and persistent. We hold the torch of life, waiting to light the lamp of science and technology!

On the road of exploration, we should benefit from Herman and lomonosov's courage to explore the secret of lightning with their lives, Philip's confidence to know himself and go his own way, and Kōnosuke Matsushita's innovation of "doing what others don't do". Therefore, I am willing to ride the long wind to break the waves in Wan Li, accumulate strength and embrace my long-cherished dream!

In the development of science and technology festival, we gradually realized the wonder of science and technology and its importance to the development of human life, and began to understand that thinking and knowledge are the ladder of national progress.

In the boundless sky of science and technology, we "look up at the vastness of the universe and overlook the prosperity of categories", but we can't talk about love; We are like children picking up shells in front of the sea of truth. We can't read the whole Qian Fan. But we will greet the new year with youthful attitude and strength, passion and thinking, we will let the lamp of science and technology ignite dazzling brilliance, and we will let the voice of China resound through the east of the world!

Students, do you want to be scientists? Want to win the Nobel Prize? Want to have Einstein's intelligence? If you want, come to our science and technology festival! The activities of the science and technology festival have their own uses. Let me introduce you one by one.

The first is a jigsaw puzzle, which can make your brain turn quickly in an hour. Greatly improve the intelligence of your brain. Let your imagination play, the weirder the better.

The second event is a helicopter competition, in which each student takes his own plane. The plane flew up and down over the playground, like a big dragonfly flying nimbly in the blue sky. The plane hovered in the air for a while, then rose into the sky and flew over our heads, as if it were a bird flying freely in the air. I can predict that one of my classmates may fly to Mars in the 22nd century. Ah, people can fly for a while in 2 1 century.

Although the helicopter competition is wonderful, it is not as intense as the four-wheel drive competition. Ready, go! "With the loud voice, their car began to run. At first, there was a girl's car in front. At the corner, a big brother's car came and floated to catch up with the girl. On the "S" curve, the girl bravely caught up and crossed it with a straight line, and the girl took the lead again. It's the platform. Our car is very heavy. Brother fell down. The girl's car is very light. She can fly. When she got on and off the bus, it looked like an eagle was chasing a rabbit. After a beautiful arc, the girl's car fell down gently, and the "faucet" in front "buckled" the big brother's car. In this way, the girl became active and the eldest brother became passive. At the sharp turn ahead, the girl's Xiangqian Che swung, accelerated sharply, and unbuttoned. Due to inertia, the big brother's car was thrown off the runway at once. I thought to myself, that little girl is really something. Although she is in a primary school, she is very good at playing four-wheel drive. She must have spent a lot of effort at home!

Science and technology festival has taught us rational thinking methods, cultivated our practical ability, and cultivated our scientific literacy and cooperation ability, which really benefited us a lot! Thanks to the teachers' careful guidance and help, and thanks to the school for providing us with this big stage, so that we can freely display our imagination, freely display our talents and freely learn and grow.

Science and technology festival essay 10 the science and technology festival ended with a bang. It seems that I have just finished a festive festival and completed a rich learning course.

Our students are bold and innovative in the design of various competitions in the science and technology festival, and they can also take into account the aesthetics of the design! This is a kind of self-style gradually formed by students under the environment of being the first and striving for the first place in pre-hospital primary schools. In the "Eggs Hit the Earth" project, the students' designs are novel and peculiar, and they can skillfully use light materials to protect eggs from damage. In the design of environmentally-friendly fashion, students are both designers and models, and the materials used to make these exquisite fashions are all ordinary items that we think are abandoned by waste products. The ingenuity of the students and the ingenuity of every designer surprised me! Students have applied their knowledge to their own creation! At the science and technology festival, the potential hidden in students' bones on weekdays is fully displayed, like a fire!

I personally participated in China Volleyball Never Falling. In the competition, I realized that teamwork is very important. To complete a job, many people often need to work together. Everyone can complete different parts of the task, and only by combining these seemingly scattered parts can they succeed. One person alone often cannot achieve good results. Science and technology festival has taught us rational thinking methods, cultivated our environmental protection ability, and also cultivated our scientific literacy and cooperation ability, which really benefited us a lot!

Thanks to the teachers' careful guidance and help, and thanks to the school for providing us with this big stage, so that we can freely display our imagination, freely display our talents and freely learn and grow. thank you

Science and technology festival essay 1 1 under the bright sunshine, our wisdom and sweat are flowing; In the fierce debate, the sparks of our thinking collide; The complicated operation embodies our pure friendship. In the beautiful campus, there are our energetic figures, the joy of applying what we have learned, and our passionate youth.

The Science and Technology Festival kicked off. I am honored to attend the first science and technology festival of Shashi Middle School. I signed up for the "Eggs Hit the Earth" activity with four other students. Oh, what a vivid name!

On that sunny noon, several students came to school. We brought foam, sponges, plastic cups and, of course, eggs ... and worked hard for more than three hours. Finally, something like a flying saucer was born. Its protection of eggs is not broken even if it falls from the third floor. We smiled with satisfaction.

There is no royal road to science. In the game the day after tomorrow, we failed to make it to the final. The reason turned out to be that the eggs were exposed, but we sealed them. Hearing this news, we thought it was a shoo-in, and suddenly lost, lost because precious time was wasted but we didn't get the result, lost because we didn't come up with a better idea.

However, in this process, we have gained knowledge, friendship and practical ability. What is there to lose? The road to science is to experience ups and downs to achieve success. Edison tried to invent the light bulb a thousand times, Zu Chongzhi cut a circle a hundred times to calculate pi, Kepler sorted out 10 thousand pieces of data and found three laws ... Compared with them, what is our little setback? It is better to sing "Qian Fan on the sinking boat side, ten thousand mu village in front of the sick tree" and wait for the next chance to enjoy the joy of failure.

On the other hand, the purpose of science and technology festival is to cultivate our interest in science and increase our knowledge. Set up our lofty ideals in small inventions. That egg carries interests, knowledge and ideals, not just the honor of the first prize. The acceleration of gravity when he falls will push us further and further on the road of science and technology, and it will become a beautiful stroke in our passionate youth.

At the end of this year, no one was depressed by the cold wind in winter. Everyone is immersed in the novel inventions brought by the "technology caravan" and immersed in deep thinking about science. In class, the students listened carefully, and in class, the teacher was surrounded. What a harmonious science and technology festival! Technology makes life better!

Looking around the world, all countries regard "science and technology is the primary productive force" as the basis of development. Our great and ancient nation, with the efforts of generations of young people, will certainly become a big country in science and technology. At that time, I believed that the Nobel Prize was not a dream, the moon landing was not a dream, and the flying of dragons was not a dream!
