Science and Technology Festival Essay 1

One Hundred Scenes of Xiantao

My hometown has a name that makes foodies salivate, and that is "Xiantao". Xiantao, it is a city with cloud-like scenery; Xiantao, it is a city with many delicious foods; Xiantao, it is a city that is "open and enlightened, and advocates morality and advancement".

Pictures of old scenes in Mianyang

I often listen to the older generation telling stories about their childhood. At that time, the name of their hometown was still "Mianyang". "Dirt roads, red brick houses, ponds and fields everywhere" the picture of backward mountain villages on TV is like the old scene of Xiantao. It is already very good to have a bicycle at home, let alone a car. . You can imagine how difficult the living conditions were at that time and how inconvenient it was to travel.

I once asked my grandparents: "Xiantao was so poor at that time, what was your study and life like?" The elders answered me: "We had very few educated people at that time. They all went to school. Those who teach elementary school in junior high schools, those who have gone to high school to teach junior high schools, and those who have gone to college, there are very few!" "When we were your age, we had already started washing clothes, cooking, and taking care of our younger brothers and sisters at home! "Children older than you, who are thirteen or fourteen years old, go out to work to make money. You are already very happy now." I compared the childhood of the older generation with ours, and then I understood what they often talked about. That sentence "You don't know how blessed you are when you are in the midst of blessings!"

New Scenery of the City

With the comparison of the past, you will discover the beauty of life now. What used to be a dirt road has now become an asphalt road. High-rise buildings have been erected on the former fields. Just last year, infrared sprinkler sensors were installed on the sidewalks at every traffic light intersection. As long as someone forcibly crosses the road at a red light, it will automatically spray water after being scanned by infrared rays to remind him to obey the traffic rules and not to pass; there is also an automatic "traffic police" who will remind you of your safety on the roadside according to the traffic lights. . Needless to say, new energy buses save energy, have no exhaust emissions, make less noise when driving, are very smooth when parking or starting, and the feeling of riding in the bus is better. Inadvertently, the development of technology has been integrated into our lives, making life more comfortable!

City Vision

Changes in technology have brought a lot of convenience to people’s lives, and people’s happiness index is also greatly improved. However, the development of science and technology is also due to the uncontrolled exploitation of resources by humans, the unreasonable use of chemicals, and the lack of proper treatment of sewage. The balance of the natural ecology has also been seriously damaged. I not only hope to change ecological environment problems through science and technology, but also want my hometown to receive better planning and development 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 vehicles are diverted on the wide road, and people are busy in an orderly manner, with happy smiles on their faces.

To achieve these changes, you must start from yourself, care for the environment, abide by traffic rules; learn to classify garbage and allow recyclable resources to be properly utilized. Let us study hard, become a useful person, contribute to the construction of our hometown, and look forward to the bright future of Xiantao together! Science and Technology Festival Essay 2

Since the invention of the steam engine, humans have entered the industrial age; since the invention of the light bulb, humans have lived a bright life; since the modern Internet developed, humans have used computers and mobile phones. , TV...

In ancient times and now, because of technology, people’s lives are completely different!

Many years ago, people had to carry heavy goods on their backs to barter for purchases. A few decades ago, there were canteens and supermarkets, and you could buy things with just a wad of money. Well now, you can shop online on your mobile phone, and you can buy things with just a few clicks of your finger.

In primitive times, wherever people wanted to go, they could only go on foot. Gradually, people had simple means of transportation such as boats and sedan chairs. Now, many novel means of transportation are emerging... Cars, trains, high-speed rails, airplanes and other means of transportation have become ordinary.

Technology benefits mankind and expands mankind’s horizons.

In primitive times, humans wanted to know: What is on the other side of the mountain? Gradually, as I learned what was on the other side of the mountain, I wanted to know: What was on the other side of the sea? Now, we know what is on the other side of the mountain? What's on the other side of the sea? He also has a certain understanding of the universe that the ancients longed for!

From sedans to cars to high-speed trains, there are changes everywhere; from bartering to currency to online shopping, there are changes everywhere; from sundials to clocks to electronic clocks, everything is changing. There are changes...

Einstein said: "Science is never-ending, it is an eternal mystery." In the future, we will definitely live up to expectations. As long as there is technology, the future will be better.

Needless to say spaceships in outer space, or detectors in the depths of the ocean, changes in lifestyle and technology alone can create the future! Science and Technology Festival Essay 3

Before 1986, Xiantao was just a small, somewhat backward county. After being withdrawn as a county city in 1986, this small town was transformed into a new type of city, with the vibrant name "Xiantao".

Just from the traffic, you can see the great changes in Xiantao. At that time, my parents had to walk everywhere. If you wanted to go to a distant town or urban area, you had to take a "passenger car" - there was no such thing as a bus at that time. But what to do when traveling far away?

Of course, riding a bicycle is also a good way, but not many people had bicycles at that time. Later everyone got on their bicycles and cars came and went on the road. It is inconvenient to have bicycles lying sideways or even upside down in a pile. After all, there are still people walking, and the problem remains.

Things are different now. “SUV” and “4S” stores with considerate services are popping up one after another. The traffic lights on the left and right sides of the sidewalk repeat warm words of no passage or safe passage. A conspicuous electronic screen at the intersection scrolled through promotional articles such as "No traffic accident, only happiness comes when you get home safely." The road is busy with traffic, but it is orderly.

In the past, when traveling to distant places, people could only go to the neighboring city of Xiantao and take a train. Always arrive an hour or two in advance before going. How can I play well if I am not in good spirits?

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

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

In the past Mianyang, now in Xiantao, the traffic has undergone earth-shaking changes. According to the plan of Hubei Province, Xiantao will become a regional central city in the near future! Science and Technology Festival Essay 4

The annual Science and Technology Festival is here again. The weather is very good today. It is a special and good day for all our teachers and students in the school. The Science and Technology Festival is a major tradition of our school and a grand gathering of science and technology activities. During this week, the school will develop different activities and competitions for students of each grade. The activities of the seniors of the high school are very high-end. There are all kinds of models. Our activities are simple, fun and exciting.

It is said that the spirit of a festival lies in its atmosphere. The Science and Technology Festival adds a layer of science and technology to our entire school. Walking in the school, you can often see the figures of senior students experimenting with models. In the teaching building, there is often laughter among students competing in various competitions. Every student has been influenced by science and technology.

Our activities include paper airplanes and target shooting, paper airplane levitation and bamboo dragonflies, which made the class a lot more lively. The students studied several ways to fold paper airplanes, so during their spare time, paper airplanes "flyed all over the sky". In addition, in the corridor, some students were trying to fly bamboo dragonflies again, or dragging a board to carefully "push" the paper airplane forward. I participated in bamboo dragonfly and hover plane competitions.

The real excitement of the event is during the competition. The bamboo dragonfly competition is at noon on Wednesday. Despite the scorching sun, there was still a buzz of people in front of the school information center. I was in a group with Wang Zichen. The competition venue was on the side of the square. Within this range, I compared the airborne time and flight distance. At that time, I felt that I didn’t fly too far, only about two meters. However, Chen Shuaihua from our class My classmates flew more than six meters away. Although I don’t know the results yet, I believe our class will be very good.

The most exciting competition is the paper airplane target shooting and levitation on Thursday afternoon. The competition venue is in the school stadium, where all the students and teachers from the first and second grade of junior high school gather together in a lively manner. Compared with seven other classmates, I was suspended. Before the game time has come, everyone is practicing continuously. As the saying goes, "If you sharpen your skills in battle, you will lose your happiness if you are not happy." As soon as the competition started, we showed our strength. Everyone took turns to "transport" the plane to the finish line in an orderly manner, striving for stability and health. For me, except for the first one that flew out of bounds, I played normally afterwards and felt very good about myself. In the final result, our class won the second prize, and the paper airplane shooting won the first prize.

The Science and Technology Festival has ended happily, and we have also gained a lot. We have gained insights in competitions and exercises, and also exercised our teamwork skills. There are many daily activities in Hangzhou. These colorful activities allow us to 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 this annual Science and Technology Festival! Science and Technology Festival Essay 5

Water is no stranger to everyone. It can be seen when people drink water, brush their teeth, wash their faces, make soup, and wash clothes. However, water is actually very mysterious. Do you want to know its mystery? Then just listen to me.

First, let’s take a look at water quality. Tap water actually contains many minerals. At the same time, the quality of water is closely related to its PH value.

Let's do a little experiment. I prepared two glasses of water, one is tap water and one is purified water. At this time, both glasses of water are colorless and odorless. I dropped two drops of the PH reagent into the tap water, shook the cup gently, and the tap water immediately turned light blue. Comparing the PH value color chart, it showed that the PH value was 8.0. I used the same method to test the purified water again. The color was a bit dark blue, and the displayed pH value was about 8.5--8.7. It can be seen that both types of water are alkaline. Then, I placed a conductive pen in the two kinds of water, and a red light lit up on the tip of the pen, indicating that they both contained minerals. Next, I dropped two drops of residual chlorine into the two types of water. The comparison showed that both contained 0.1 residual chlorine. Experiments show that both water qualities are beneficial to the human body.

The secrets of water don’t stop there. Water can also exhibit a wide variety of crystals. The water crystals formed by seeing and hearing different words are just like the mood of people when they see and hear these words. When it sees words such as love and gratitude, the water crystals are neat and beautiful; when it sees hurtful and vicious words, the crystals formed by the water are terrible, and sometimes no crystals can form. Perhaps, there is only gratitude and love in nature!

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

Everything in the world comes from water. Without water, there is no life. This shows how magical water is! However, most of the world's water sources have been damaged and polluted, and are no longer as pure or clean as before. The wars in the world now are over oil, and the wars in the future may be over pure water sources. Therefore, we all need to cherish water! Science and Technology Festival Essay 6

In December, the snowflakes that have been absent for a year lazily arrived, decorating the earth into a world covered in silver; Danmei showed her face generously in a brocade skirt, filling the air with a sweet and refreshing taste... In December, imagination gave wings to technology, and innovation flowed in the first Science and Technology Festival held by our school. The campus Full of sparks of wisdom collision!

In the egg hitting the earth competition, the egg and the earth had a friendly and close contact, and creativity made the egg and the earth embrace each other affectionately. In the process of designing the installation, the students came up with many unique ideas, took it seriously, and overcame difficulties. Although their hands were covered with glue, the joy of creation was irreplaceable. Although the process was accompanied by disputes, the collision of ideas was sparkling; Although we did not make it to the finals, the fun of participating has become an indelible treasure in our memory!

The egg hits the earth, making the egg dance like a flower, and let the thought follow the falling trajectory!

Draw the school map and let the brush flow freely on the paper!

Make a metal tree and let substances combine to create brilliant colors that burst out!

In the Science and Technology Festival, we also saw various exhibits. "Water without a Source" allowed us to admire the designer's whimsical ideas; "Probability Estimation" allowed us to appreciate the infinite fun in mathematics; "Rolling up the vertebra" allows us to experience the impact of visual illusions... When we linger in front of one exquisite exhibit after another, we are amazed, excited, and hopeful...

Technology is constantly developing Yes, the pace of science never stops like time, and we need to continue to explore.

"Smiling at the wind and clouds, looking down on the big country", this is a portrayal of Mr. Ye Duzheng, the country's top science and technology laureate, an elder who continued to explore in his scientific career and vowed to "let foreign countries People come to join us." He was "already the founder in his prime, and he is still a pioneer in his seventies." Now, in our prime, we should also have such a pioneering spirit and stand on the shoulders of giants. We should not be afraid of exploration and move forward bravely!

I once heard something that has always touched me. It was said by a college student in a speech: "We work hard to learn English today so that the whole world will work hard to learn Chinese in the future." Now for us In other words, so is technology! I want to say: Today we are working hard to explore in the world of science to make our dreams fly and to make life better!

"The wise are happy, the benevolent live long, and the explorers open up new territories. I was young and frivolous, but now I am in full bloom. I will be diligent in thinking every year, dreaming about science and technology, and having lofty aspirations." , Dreams have infinite possibilities, Qingqingziqiu, use wisdom to open life, decorate the world with technology! ”

In the Science and Technology Festival, we learned to think well, learn to innovate, and learned to cooperate in science! In the ocean, everything is possible. Let us use actions to interpret the meaning. One day, we will see the power of water droplets to penetrate rocks! Science and Technology Festival Essay 7

Time flies like an arrow, and the sun and the moon fly by. Time flies so fast, it’s already 2110. Our country's science and technology is also developing rapidly. After scientists' continuous efforts, continuous experiments, and continuous improvements, they have created the "Cosmic Living House" and realized people's desire to live in the universe.

Now let me introduce this great invention to you!

The universe living house is round. In order to be more conspicuous in the universe and to avoid accidents, scientists designed it to be bright silver.

It is mainly divided into two floors: the lower floor is for 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 may be curious, why does the Universe Life House have no kitchen? Let me answer it for you. We planted the vegetable and fruit seeds brought from the earth on the moon, which has special soil. After being cared for by the gardener robot, we produced large and delicious organic fruits and vegetables. Your mobile phone will be bound to the system of the Universe Life House. As long as you click on the "Tiantian Cuisine" voice on the mobile phone and say the name of the dish you want to eat, the "Small Caish" system will immediately notify the cosmic porter to deliver fresh vegetables from the moon. Cook for you again. In three minutes, you can enjoy a delicious meal.

When you want to rest, click "Sleep Peacefully" and the Universe Life House will turn on the sleep mode. All objects in the Universe Living House are stationary, the walls are replaced with soundproofing, and a beautiful lullaby will be played for you... Don’t worry about there being no oxygen in the Universe Living House. Scientists have already solved it. After the gases in different planets are synthesized, it is exactly The oxygen we humans need! The Universe Living House is equipped with void pipes, which can easily input oxygen into the house, plant some plants and trees, and you will have fresh oxygen!

The Universe Living House is not only convenient and comfortable to live in , it can also drive like a car and take everyone to travel in space.

Start the "ship" in the cockpit and drive it, and you are ready to travel. But pay attention to the space signal lights! The space life house can automatically cruise. Just press the big yellow button. After confirming the direction, click the blue button. The walls of the living room are replaced with glass. You can lie on the sofa and admire the beautiful planets. How amazing it is. It feels so refreshing!

There are many more functions of the Universe Living House, come and experience it!

How great and incredible the power of technology is, let us create more amazing things together Invent it! Science and Technology Festival Essay 8

Who traced numbers with tree branches in the distant sky of ancient civilization? Who regulates nature with laws in the endless motion of objects? Who uses magic to turn stones into gold in the ordinary wilderness?

Who illuminates the night, and who conquers the sky?

It is the lamp of science and technology, leading the world to change with each passing day, and guiding mankind from ancient times to the future.

The prehistoric years come again and again. Walking along the green water bank, we can still hear the voice of ancient human wisdom echoing in the air. Perhaps since the beginning of the world, the lamp of science and technology has been lit!

When the first beam of fire burst out from the sound of chiseling wood, and when the first ax was born from the collision, I seemed to hear the rustling of the life of technology. Time passes through the vicissitudes of time like a fleeting moment. The looming secrets in the Egyptian pyramids and the exquisite number calculations are like the splendor of spring flowers; the miracles of China's four great inventions, the brilliance of papermaking, and the glory of the compass are like the scenic wonders at the source of the river.

Lighting the lamp of science and technology is the playing of the song of life and the strong voice of the pace of the times.

Technology promotes reality and accelerates the pace of the times.

From the poets singing and getting drunk, and chanting about the lime that has been hammered out of the mountains for thousands of times, to today’s towering buildings and huge factories; from Beijing’s ancient courtyard houses to today’s villas and real estate; from history From the forgotten "gray-green ocean" in the book to the enduring trend of clothing matching... The development of science and technology has made changes everywhere, setting up high cloud sails for life.

Technology is not just a human instinct to seek knowledge, it is also a product of deep thinking.

Hua Luogeng once said: "The ability to think independently is an essential talent for scientific research and inventions. Any more important scientific creations and inventions in history are all related to the creators and inventors. "We young people should learn to think independently and innovate with technology." "The history of knowledge is like a great polyphony, in which the voices of all nationalities sound in turn." This is Goethe's poetic language. He tells us that the falling stars of knowledge will form a beautiful waterfall, and this What roars out of the waterfall is the never-ending footsteps of a nation.

Let us light the lamp of technology!

Our youth is the early stage of life. We have the most unique charm among the four seasons, and we have stunning scenery. We are optimistic and confident, but also strong and persistent. We already have the torch of life and are waiting to light the lamp of science and technology!

On the road of exploration, we need the courage of Lichman and Lomonosov to use their lives to explore the secrets of thunder and lightning, the confidence of Philip to know himself and go his own way, and the confidence of Konosuke Matsushita." Do what others don’t do” innovation. Therefore, I am willing to ride the long wind and break through the waves, accumulate strength, and embrace the dream that I have longed for!

In the course of the Science and Technology Festival, we gradually appreciate the wonder of science and technology and its importance to the development of human life. We begin to think clearly and understand that knowledge is the ladder of national progress.

In the vast sky of science and technology, we "look up at the vastness of the universe and look down at the prosperity of categories", but it is not enough to talk about the secrets of love; we are like the child picking up shells in front of the sea of ??truth, we cannot Read all the sails.

But we, with the attitude and strength of youth, will bring new years with passion and thinking, we will make the lights of science and technology light up with dazzling brilliance, and we will let the voice of China ring from the east of the world! Science and Technology Festival Essay Collection 9

Students, do you want to become scientists? Want to win a "Nobel" prize? Want to be as intelligent as Einstein? If you want it, then come and participate in our Science and Technology Festival! The activities of the Science and Technology Festival each have their own purposes. Now, let me introduce them to you one by one!

The first one is the jigsaw puzzle competition. The jigsaw puzzle can make your brain spin rapidly within an hour. Greatly improve the intelligence of your brain. Let your imagination run wild, the more bizarre the better.

The second event is the helicopter competition. Each student competes with his own plane. The plane sometimes flew high and sometimes low over the playground, as if it were a big dragonfly flying nimbly in the blue sky. The plane circled in the sky for a while, soared straight into the sky, and flew over our heads, as if it were... A little bird flies freely in the sky. I can predict that the airplane a certain classmate holds may be an airplane that can fly to Mars in the 22nd century. Ah, the applause that people in the 21st century can fly into for a while.

Although the helicopter competition is exciting, it is not as intense as the four-wheel drive competition. Get ready, let’s start! "As soon as the loud voice came out, their car started to fly. At first, there was a girl's car in front, and when they reached the corner, a big brother's car came and drifted to catch up with the girl. "S " On the curve, the girl chased bravely and crossed it in a straight line. The girl was in the lead again. When we got to the jumping platform, the big brother's car was heavy and the big brother fell down. The girl's car was light and flew up and down. , as if it were an eagle chasing a rabbit. The girl's car fell gently after a graceful arc, and the "faucet" in front "locked" the big brother's car. In this way, the girl became. Instead of taking the initiative, the eldest brother became passive. At the sharp turn ahead, the girl's car "swung forward", accelerated sharply, and unbuckled. Due to the effect of inertia, the eldest brother's car was pushed forward. The child was thrown off the track. I thought to myself: That little girl is really amazing. Although she is young, she is very capable in playing four-wheel drive. She must have put in a lot of effort at home!

The Science and Technology Festival taught us rational thinking methods, cultivated our hands-on ability, and also cultivated our scientific literacy and ability to cooperate with others. It was really beneficial! We are grateful to the teachers for their careful guidance and help, and to the school for helping us. It provides this big stage so that we can freely express our imagination, freely let our talents show, and freely learn and grow. Science and Technology Festival Essay 10

It seems that the Science and Technology Festival has just ended. After completing a festive festival, it feels like participating in a rich learning course.

Our students’ designs for various competitions in the Science and Technology Festival were bold and innovative, and they also took into account the aesthetics of the design! This is a kind of self-style that the students gradually formed under the environment of Yuanqian Primary School where they dared to be the first and strive for the first place. In the "Egg Hitting the Earth" project, the students' designs were novel and unique. They can cleverly use lightweight materials to protect eggs from damage. In environmentally friendly fashion design, students act as both designers and models, and the materials used to make these exquisite fashions are made from some ordinary materials that we think are inconspicuous. They are discarded items. I was surprised by the ingenuity of the students and the uniqueness of each designer! In the Science and Technology Festival, the students all applied their knowledge to their own creations! The potential that is usually hidden in the bones is fully displayed, as bright as a fire!

I personally participated in the "Chinese Volleyball Never Fall". During the game, I realized that teamwork is very important. Importantly, to complete a job, many people often need to work together. Each person completes different parts of the task. Only when these seemingly scattered parts are put together can success be achieved. One person often cannot achieve much by working alone. Good results. The Science and Technology Festival taught us rational thinking methods, cultivated our environmental protection capabilities, and also cultivated our scientific literacy and ability to cooperate with others. It is really a benefit to us.

Thank you to the teacher! For your careful guidance and help, I would like to thank the school for providing us with this big stage so that we can freely use our imagination, freely let our talents show, and freely learn and grow. Thanks! Science and Technology Festival Essay 11

Under the bright sunshine, the sweat of our wisdom flows; in the fierce debate, the spark of our thinking collides; in the complicated operations, our innocent friendship is reflected. In the beautiful campus, there is our energetic figure, our joy of learning and applying, and our passionate youth.

The Science and Technology Festival has begun. What an honor it is for me to participate in the first Science and Technology Festival of Shashi Middle School. Together with four other classmates, I signed up to participate in the "Eggs Hit the Earth" activity. Oh, what a vivid name!

On that sunny noon, several classmates came to school. We brought foam, sponges, plastic cups, and of course eggs... and worked on it for more than three hours. Finally, something resembling a flying saucer was born. It protects eggs even after being dropped from the third floor without breaking.

We smiled with satisfaction.

There is no smooth road on the road to science. In the game the day after tomorrow, we failed to reach the finals. The reason turned out to be that we sealed the egg when it should have been exposed. When we heard the news, we who thought we were sure of victory were immediately extremely disappointed. We were disappointed that precious time was wasted but no results were achieved, and we were disappointed that we did not come up with better ideas.

However, in this process, we have gained knowledge, friendship, and hands-on ability, so what is there to lose? The road to science is about going through ups and downs before achieving success. Edison experimented thousands of times before inventing the light bulb, Zu Chongzhi calculated pi by cutting a circle hundreds of times, and Kepler discovered the three laws after sorting through tens of thousands of data... Compared with them, what are our small setbacks? It is better to recite "Thousands of sails pass by the side of the sunken boat, and thousands of villages in front of the diseased trees" to wait for the next opportunity and enjoy the joy of failure.

From another perspective, the purpose of the Science and Technology Festival is to cultivate our interest in science and increase our knowledge. Establish our lofty ideals in the creation of small inventions. That egg carries interests, knowledge and ideals, not just the honor of first prize. The acceleration of gravity when he falls will push us further and further on the road of science and technology, and will become a beautiful part of our passionate youth.

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

Looking around the world, all countries regard "science and technology as the primary productive force" as the basis for development. Our country, a great and ancient nation, will surely become a technological power with the efforts of generations of young people.

By then, I believe that the Nobel Prize is not a dream, landing on the moon is not a dream, and the dragon soaring is not a dream! ;
