Saturday morning, the teacher is going to take us together to visit the exhibition of science and technology, heard the good news, we are all happy jumped up and down, and their mouths have shouted, "Great. " After listening to the teacher's account of the matter, we lined up in a neat line on the bus.
A came to the door of the Museum of Science and Technology, we are like just released from the cage of the birds, as fast as rushed in. Can not help but touch the east, west look, every exhibit is full of curiosity. Teacher said, "the study of scientific and technological knowledge can not go through, we should not only recognize it, but also to understand its reasoning." We then quieted down and began to concentrate on careful observation.
We first came to a booth, saw a sign, which reads: "Leopard in the tube". This is a small square booth, the screen is black, there is nothing special, there is no switch, but in the lower left of the screen placed a large "magnifying glass", this thing is what to do?
I was curious to pick up the "magnifying glass", at this time, a passionate music gushed out, I was shocked, thinking: how the screen turned white, is it I broke the machine? When I was so panicked that I didn't know what to do, the teacher said, "Put the magnifying glass on it and look at it!" I probed to see, only to see the magnifying glass there is a fit leopard is a large beautiful grassland, running to hunt for food!
I was surprised, moved away from the magnifying glass, the screen is back to a white, nothing can be seen. Why is this? This is the teacher came over. "LCD display is a backlight, lower polarized light, upper polarized light composition, one without the other, only when the two polarized light parallel, the picture can be displayed, and in front of this display in the upper polarizer was installed inside the magnifying glass, the screen is only 3 kinds of parts, so the screen is white. It's the same reason we usually need to wear glasses when watching 3D movies." The teacher patiently explained the mystery to us, it's so interesting!
After visiting the "Leopard in the tube", I also watched the "dancing paper clip". See in a round basin filled with many colorful paper clips, as long as the "start" button, they will dance with the rhythm of the music, they a moment "stand up", a moment of "down! ", sometimes like a lovely little loach drilling in the soil, sometimes like the students with the wonderful music in the morning exercise, it looks very interesting, led to the students laugh, and even some students followed them together with a happy dance.
Then you know why the paper clip will "dance"? Because there is a coil device in the bottom of the large disk, energized to produce a magnetic field, play music, the coil will follow the ups and downs of the music, regularly energized and de-energized, paper clips are magnetic, when energized, the magnetic force increases, paper clips can "stand up", when de-energized, the magnetic force disappeared, the paper clips are "When the power is cut off, the magnetic force disappears and the paper clip "falls down". Wow! Science is really interesting!
I saw a screen below a five-pointed star, it is called painting a five-pointed star, with an iron pen along the side of the five-pointed star painting ......
I saw a lot of high-tech on this visit, these are scientists with the labor and wisdom of the invention of the, I'm really proud of them, I feel that the invention of these people is great. I feel that these inventors are really great, I secretly swear: I must to study seriously, and in the future grow up to be an inventor, to contribute to the motherland!

This afternoon, I have the honor and the school's more than a dozen students, together with the Rongcheng Middle School organized by the Science and Technology Festival activities.
At noon, the teacher told us that we were going to Rongcheng Middle School to participate in an activity in the afternoon. After lunch, we took the bus to Rongcheng Middle School. Along the way, we talked and talked and talked, not knowing what kind of activity it was today. When we arrived at Rongcheng Middle School, I realized that today was their 10th annual Science and Technology Festival. Science and Technology Festival! This is the first time I've heard of it. I've never heard of it before, and I'm instantly interested in this event.
The teacher led us to the playground, which was huge. Northeast around a lot of students, they are experiencing interesting science and technology small production. This year, learning some physical knowledge, I found that in fact those small production are made according to certain physical principles. I think one of the most interesting and proves that basic fact is the one that explores the propagation of sound in different media. It has a sound source making sound in an iron box, put a round piece of glass on top of the box, and then use different sticks (iron stick, glass stick, wooden stick) on top of the glass and put your ear on top of the stick. Through the experiment, we can come to the conclusion that sound can propagate in solids.
After visiting the small production, a beautiful young teacher came to the table in front of us with a bowl of water. She poured a little of our usual dishwashing detergent, and squeezed a little of the methane on the table, and in a short while, many small bubbles gradually appeared on the water. The teacher held up a pile of bubbles in her right hand, and with her left hand, she held a lighter towards the bubbles, and they instantly burst into flames. But this flame didn't need to be extinguished with water or a fire extinguisher, you just needed to hold your hand tightly and then release it. I wanted to try it, but I was afraid of the pain, but seeing that my classmates were not afraid, I bravely extended my hand. The moment the foam burned, I felt my body trembling, but there was no burning pain at all, even though there were flames in my hand. The teacher told us that the magical "flame" was made by injecting methane into the detergent water, which formed an internal flame after it was ignited. Since the inner flame does not supply enough oxygen, the combustion is incomplete, so the temperature is lower than that of the outer flame. We don't feel the pain, naturally.
After learning about the magical flame, our protagonists became two robots. One is designed to look like a human, while the other looks like a big crab. The "big crab"
was called "little gecko" by another companion, and it was not happy about it, "We are all robots, how can you look down on me! So the companion put on "Pure Land of Ultimate Bliss" and danced to it. The "big crab" also dare not slow down, hastily dance, although the movement is not so graceful, but I think a robot can do so many difficult movements, has opened our eyes. Now a variety of robots have gradually integrated into our lives, have to lament the progress of science and technology.
After enjoying the robot show, our activities were almost over. On the way back, we can not help but exchange their own feelings. I have benefited a lot from this activity, a seed of science and technology has taken root in my heart, it will certainly germinate, blossom and bear fruit under my efforts.

This morning, although it is a Saturday, but I have "whoosh" jumped out of bed, stepped on the wind rushed into the kitchen, and even the teeth can not care about brushing. A mouthful of bread, a cup of milk, keep stuffing into the mouth. Who doesn't want to sleep in on Saturday? Why, I'm sure you're asking? Because I'm going to a science fair in the morning! How can I not be excited?
Out the door, with a cool breeze, the rain covered the earth with a layer of light sand. I took my mom's hand while muttering, "Hurry up! Hurry up!" Finally arrived at the city square, the square is crowded, crowded, units of the pergola around the side of the square to form a square, when I came to the "Municipal Public Security Bureau" of the pergola, just to see the aerial camera in the air slowly rising, and now and then to turn a circle, which was all shot into a machine, in my eyes.
I saw the "Earthquake Disaster Prevention and Mitigation Bureau" crowded in front of the door, I with curiosity, want to find out, in the end, what attracted people? It was hard to squeeze in, which really shocked me, it turns out, visitors are trying to bring "search and rescue instrument" glasses, as long as the police with a special light on the instrument, you can see themselves from it. On the way to disaster relief, the police will be able to know whether there are signs of life, lock the location of people, rescue.
After watching the instrument, I rushed to the "EZVIZ Fluorite" shed, a go, into the eye is a variety of monitoring. "SI sports camera", "C2S multi-compact can Internet camera". Roadside monitoring everywhere, competing with such a strong power, monitoring through infrared detection; can be transmitted to the cell phone at any time figure, the general situation will not be false alarms.
After touring around, I can not help but sigh: China's technology is really developed ah!

In ancient times, those heavy labor through the transformation of science and technology, mechanization, automation, greatly improved efficiency and economic development, each invention, each scientific research breakthroughs, the formation of our today's colorful material world, mankind is using science and technology to pursue a better society and life, so that science and technology is closely related to human life.
As the saying goes, "There's nothing you can't think of, nothing you can't do".
In the past, people want to catch up with their relatives and friends in other places is a very difficult thing, are through the letter, but this in today's problem, since the 21st century, science and technology, especially computer network technology, the rapid development of electronic information technology, so that cell phones, computers, those expensive luxury goods into the common people's homes, and become a necessity of our lives.

In order to meet the annual "World Meteorological Day", but also in order to cultivate interest in science and technology, today we Peony Evening News 50 young journalists visited the HZ City Museum of Science and Technology together. I learned a lot of marvelous and mysterious knowledge of science and technology and meteorology, and the unique charm of science, which is unpredictable and ever-changing, y shocked my mind.
Into the hall, the first eye is a brightly colored, huge globe - "small ball to see the world". I and my classmate's good friend Feng Dingyi, Wang Shuai were firmly attracted to this huge "globe", the three of us together seriously and carefully looking for our country, we saw the map seems to be a headstrong rooster like the motherland. I can not help but excitedly point to the motherland and shouted: "Look! There - our lovely China!" .
Next, the lecturer led us reporters to visit the second floor of the museum introduces artificial satellites, the moon, spacesuits, meteorological disasters and other scientific and technological things a variety of colorful panels and models, these beautifully crafted exhibits have aroused our keen interest. Interpreters throughout the careful small reporters patiently explain a variety of meteorological problems, to help us feel the mystery of meteorology, a vivid and vivid anecdotes to lead us to wander freely in the sea of knowledge. Because the tornado wind is very strong, giving me a huge impact. It was the first time I knew how a tornado is formed! There are also space satellites, planters, tanks, which I only saw from the sci-fi movie "Wandering Earth" in front of my eyes, so vividly presented, attracted me to stop and watch, long time can not bear to leave ......
This popular science experience has benefited me a lot. I didn't realize that the earth we live on contains so many mysteries. It's true that life is full of learning! In the future, I want to study harder, start from me, start from the small things around me! The world's most important thing is to take care of our planet!

The sun smiles at me, the birds sing to me the flowers say to me, the grass is happy with me. Today the sun is particularly happy, radiant as my happy mood. Since I woke up, there was a surge of excitement in my bones. Guess what made me a Maitreya Buddha? It turns out that we are going to "enter" the Museum of Science and Technology to find the treasure of knowledge, to replenish the nutrition of the soul
To a cloudless afternoon. Dreary weather but can't sink our excited heart, can't smother our joy that painted on the face. People sitting in the car, but the heart is fluttering in the fantasy of the Museum of Science and Technology, thinking about it fell asleep, and then opened his eyes and found that he had arrived at the destination - the Museum of Science and Technology.
The teacher first left us, alone into the Museum of Science and Technology to do something, after a while, the teacher smiled triumphantly and said: "You can come in." We went in one by one.
As soon as we entered the Science and Technology Museum, we felt an unspeakable mystery, which is the same as what I fantasized about - a strong scientific and technological atmosphere. But it was too late to savor it rushed to the second floor, into the classroom, took a seat, began to listen to the lesson. But it was a bit of a struggle to sit down because I was carrying an immense, immense book bag. The class was taught by our biology teacher and went over the origin of man again. From the union of egg and sperm to a baby coming to earth in October with a cry. After class the teacher took us to the electricity gallery.
Thank goodness the teacher gave us free time to visit. Although the time is very short, but already very satisfied. In this limited time, we browse the entire exhibition hall, although we do not understand the mystery, but still look seriously. After all, there is no end to learning, if we all know these principles, then we are not students.
The exhibition hall has a demonstration of water power generation of small models, there are bicycle power generation device, there is a huge device. After opening this huge device, a pillar in the very center emits a strong light, surrounded by several mirrors, when reflecting the light to the plane directly above the plane when the plane, the plane will be driven by the power provided by the solar panels. We kept playing and playing. But then it hit me: what's the point of just playing? Like Newton when he was a child, what's the use of making things yourself when you don't even know the principles?
The teacher asked us to gather to watch this once-in-a-century Faraday cage. Before the experiment began, an adult was needed to cooperate, and under our strong offense, the teacher was finally willing to step into the Faraday cage. Entering, closing and energizing. At this time, a staff member brought a long stick, and when the stick touched the cage, an electric light appeared immediately. The teacher began to reach out and put his hands inside the cage. There was a burst of astonishment. It turned out that the person inside the cage was unharmed, but outside the cage there was still a lot of electricity, which had to make me very surprised. Subsequently watched an experiment called angry hair. In fact
is to rely on static electricity to make people's hair stand up.
After the show was over, the teacher led us into a place called "Gene Gate", where we saw the fertilized egg at each stage of the form. There we also saw a "vascular man" - a model of the distribution of blood vessels in the human body. We also watched a talk about how viruses attack our bodies.
When the teacher finished, we began to visit the entire Museum of Science and Technology, a friend and I from the physics hall of the interesting laws to the optical hall of the strange vision, and then to the electrical hall of the wonderful power. When the tour came to an end, we ended it with a 4D movie.
In the seat of the car back to school, I feel a burst of shock in my heart: noise can also generate electricity; a cage with electricity, from the outside to touch is high-voltage electricity, from the inside to touch but safe and sound; light through the oil, water, air three kinds of substances, the direction of change is also different; in the different mirrors, the presentation of the appearance of the object is also different. This write all let me feel incomparable shock, but in the shock and let me puzzled is: how the light is converted into electricity? Why do we need magnets to generate electricity? Why does light travel through different objects at different angles? All of this I do not know, I can only say that their knowledge is too shallow,
But know that their knowledge is shallow and what to do? I'm not sure if I'm a good person, but I'm a good person, and I'm a good person. I'm not sure if I'm going to be able to do that, but I'm going to be able to do it," he said.
Now we are learning time, so do not be afraid to learn bitter, learning tired. When the day of learning comes, it will realize that their previous efforts are worthwhile.
Today, I found the treasure, I know that learning is for their own learning, learning is not just learning textbooks, I also know that learning is interesting is not memorizing the concept of memorization. I believe this treasure will benefit me for the rest of my life.

The world is colorful and wonderful, science and technology is ever-changing, omnipotent. Today, the sun shines brightly, in the company of my brother, I came to the Tengzhou Han Picture Stone Museum to visit the Science and Technology Museum with great excitement.
The exhibition is divided into "electromagnetic mystery", "the laws of motion", "mathematical charm", "sound and light experience These include more than 50 popular science exhibits, educational toys, robot performances and digital science and technology museum.
There are so many interesting and fun experiments in the Museum. Among them, I was most impressed by the "dancing sound" and "Bernoulli levitation ball". In my brother's explanation I understand the dancing sound needs horn carton, reflector, vibrating membrane, white and so on to complete. The principle is: when the speaker carton with the sound vibration vibration, the carton over the air vibration state also changed, transferred to the carton above the vibration membrane on the mirror so that the mirror jump. Laser light reflected through the mirror to the white screen will produce a jumping spot graphics, with the sound changes to produce colorful images. In front of the "Bernoulli levitation sphere", my brother told me, "This is mainly a demonstration of the Bernoulli phenomenon. When the air at the exit to lift the ball, the air flow space will be compressed, when the same amount of air through this ever-smaller space, the flow rate will accelerate, when the flow rate is accelerated when the air pressure drops, the ball above the high-speed, low-pressure air and the ball below the combined effect of high air pressure will push the ball upward, this upward force is the air outlet out of the downward air flow and the ball's own gravity offset, when the two forces are in When the two forces are in balance, the ball can be suspended in the air. "Visited the Museum of Science and Technology, hands-on operation of so many scientific instruments, understand a lot of scientific reasoning, I was y attracted by the Museum of Science and Technology. In fact, the amazing science is on our side, it is our human progress ladder. I want to be a scientist when I grow up, invent more and more strange scientific supplies, so that people can enjoy the convenience and fun of science.

Since the steam engine was invented, mankind has entered the industrial age; since the electric light bulb was invented, mankind has led a bright life; since the modern network is developed, mankind has used computers, cell phones, TV ... ...
Ancient times, now, because of technology, people's lives are very different!
Years ago, people buy to carry heavy goods to the road to barter. And decades ago, there are kiosks, supermarkets, with a light pile of money to buy things. Now it can be good, in the cell phone can be online shopping, as long as the finger point a little can buy things.
In the primitive era, people wanted to go wherever they wanted, they could only go on foot. Gradually, people have boats, sedan chair these simple transportation. And now, many novel transportation is rising ...... cars, trains, high-speed rail, airplanes and other transportation has been flat.
Technology benefits mankind and expands his horizons.
The primitive era, human beings want to know: what is on the other side of the mountain? Slowly, knowing what is on the other side of the mountain, they wondered: what is on the other side of the sea? Now, we already know what is on the other side of the mountain? What's on the other side of the sea? Also have a certain understanding of the ancient people full of yearning for the universe!
From the sedan chair to the car, and then to the high-speed rail, there are changes everywhere; from barter to the emergence of money, and then to online shopping, there are changes everywhere; from the sundial to the clock, and then to the electronic clock, are changes everywhere ......
Albert Einstein said: "Science is never-ending, it is an eternal mystery." In the future, we will certainly live up to our expectations, as long as there is technology, the future will be even better.
There is no need to talk about spaceships in outer space, or the depths of the sea went to the detector, the single change in lifestyle, technology, can create the future!

In 86 years ago, Xiantao is still just a somewhat backward small county. In 86 years after the abolition of the county to become a city, this small city changed into a new type of city, there is a "Xiantao" this energetic name.
Just from the transportation, you can see how much Xiantao has changed. In the days of mom and dad, you had to walk everywhere. If you want to go to the farther town or city, you have to take the "bus" - there is no bus at that time. But what about going out of town?
Of course, bicycling was a good way to get around, but not many people had bicycles. Then everyone got on a bike, and the road was full of cars. It's not convenient to have a bunch of bikes sideways, diagonally or even upside down. After all, there are still people walking, the problem is still there.
Now it's not the same, with all the SUVs and 4S stores popping up all over the place. The traffic lights on the sidewalks repeat the message of no passing or safe passage. The prominent electronic screens at intersections broadcast a scrolling propaganda message that traffic is no small matter, and that safety is the only way to be happy at home. The road is crowded with cars, but it's also very organized.
In the past, when traveling to distant places, people could only go to the neighboring city of Xiantao to take the train. Every time before going, but also an hour or two in advance. The spirit of the child is not good, how can play well?
But now Xiantao people do not have this trouble. People in their hometown can also get on the train to the other side of the country. Xiantao station has been opened, not to mention the Xiantao West Station. Foreigners again asked about Xiantao there is no train station, we can also proudly answer a sentence: "We have, there are several!"
Not only that, Xiantao airport also appeared in front of people. I even had the honor of visiting it!
Once in Shinyang, now in Xiantao, the transportation has changed dramatically. In the planning of Hubei Province, Xiantao will soon become a regional center city!

Science and technology festival ended with a bang. It was as if we had just finished a festive holiday, and as if we had finished attending a rich learning program.
The design of the competitions in the Science and Technology Festival, our students conceptualization bold, innovative, but also take into account the beauty of the design! This is in the courtyard before the elementary school dared to be first, the first environment of the breeding, students slowly formed a kind of self style. In the "Egg Crashing" project, the students' designs were novel and strange, and they were able to skillfully use lightweight materials to protect the eggs from damage. In the environmental fashion design, students acted as both designers and models, and the materials used to make these beautiful fashions were all unremarkable and discarded items that we usually consider waste products, which surprised me with the ingenuity of the students and each designer's ingenuity! The students applied their knowledge to their own creations! In the Science and Technology Festival, students usually hidden in the bones of the potential to show out, as if it is a fire like dazzling!
I personally participated in the "Chinese volleyball never fall", in the game I understand that teamwork is very important, to complete a job, often need many people to work together, each person to complete the task of the different parts, in these seemingly fragmented parts together, in order to succeed. It is often impossible to achieve good results with just one person working alone. Science and Technology Festival teaches us rational thinking methods, develops our environmental protection ability, but also develops our scientific literacy, the ability to cooperate with others, really benefited a lot!
Gratitude to teachers for our careful guidance and help, thanks to the school to provide us with this big stage so that we can freely play the imagination, free to let the talent show, free to learn and grow. Thank you!
