On a sunny day in winter vacation, my parents took me to Baotou Children's Science and Technology Museum, which was crowded with people. I thought to myself: there are so many people who like technology!
When I entered the Science and Technology Museum, the first thing I saw was a very large kaleidoscope. I walked a few steps forward and saw a robot playing the piano. It was lovely. There is a maze of thousands of mirrors next to the robot. Suddenly, a few big characters on a sign caught my eye. "Why is there only life on the earth in the solar system?" That's what I've always wanted to know. Is there a home on earth called the solar system? Doesn't the earth exist alone? Is there only life on earth? I walked into the mysterious little room with strong curiosity.
Aunt, a very beautiful commentator, smiled and explained to us the origin of life on earth. It turns out that life cannot exist without water, air, sunshine, proper temperature and nutrients needed for life. In the solar system, the distance between the earth and the sun is moderate, so the light received by the earth and the temperature of day and night are suitable for life, while other planets are either too close to the sun, too far away, or not attractive enough for life. After listening to the introduction of the commentator's aunt, I suddenly realized that the earth belongs to one of the eight planets in the solar system. Because the earth is in a moderate position from the sun, there are important factors suitable for the existence of life on earth. They are water source, suitable temperature and sufficient sunshine, so there is life only on earth.
The universe is really amazing. I must come to the Science and Technology Museum more often to explore the mysteries of the universe. Study hard, become a scientist when you grow up, and continue to explore some unknown secrets in the universe.

When we arrived at the Science and Technology Museum, before the teacher showed us to the new exhibition hall, we rushed in shouting as soon as the teacher announced the dissolution. I didn't visit blindly, but read the tour introduction first and learned what was on each floor before I went to visit.
First, I visited the first floor. The main building on the first floor should have four exhibition areas: machinery, materials, transportation, energy and aerospace technology. We know about nano-nano technology and arranging atoms in the first layer. Then I came to the second floor. There are modern communication technology, virtual human reality, display technology, microelectronics technology, sensors, electronics and computer application technology on the second floor. Later, I went to the third floor. The third floor is the most interesting one. I am very interested in the third floor, because there are several exhibition areas on the third floor, such as environment, life, high voltage discharge, sound, light, electromagnetism, brain science and mathematics, which are similar to the knowledge mentioned in our textbooks, so I am very interested. One of the exhibition projects is called. Peep into infinity? . I think it's good. This is an optical phenomenon. I can see endless repeated images in the mirror. I gently turned the frame by hand and found that the positions of all the images changed accordingly. I didn't understand what was going on, so I asked the science teacher who was visiting. The science teacher told me that this is a reflective imaging optical system composed of two flat mirrors. The front is semi-transparent and semi-reflective, and the back is totally reflective. When two mirrors are in parallel position, they have the characteristics of multiple reflection imaging. For example, if an object is placed between them, many images can be reflected. When the included angle between two mirrors is changed by rotating the mirror frame, the incident angle of light changes, so the position of the reflected image also changes. ?
After listening to the science teacher's explanation, I suddenly understood the reason for this phenomenon. I'm glad I understand a physical phenomenon.

Not long ago, I went to Xiamen for two days and went to many places. But the most impressive place is Xiamen Science and Technology Museum.
Walking into the hall, the water bell is on its way. There is a water supply box above the water clock, and there are a group of containers on both sides. The large container on the left represents 1 hour, and the small container on the right represents 2 minutes. It uses the 12 hour timing method. The whole Science and Technology Museum is divided into five theme pavilions. In the ocean and cradle exhibition hall, I learned about the mysterious ocean. In the exhibition hall of Creation and Civilization, those lifelike robots and interesting virtual worlds are amazing. The most unforgettable and exciting thing for me is that when I stepped into the exhibition hall of exploration and discovery, I found a circle of model planets, standing on the scale of the Mars model, ah! My weight is only 3. Six kilograms! Only one-tenth the weight of the earth; There is also a magical hut, which looks very flat, but the people inside are crooked and can't walk the right path; There is also a strange bucket filled with water. There is a handle on the bucket. When I shake the handle, many bubbles fly out of the water and dance like a dancer, huh? When you shake this handle, why does it fly out of the dancing bubble? It turns out that when the handle is shaken, it will drive a vertical rod with a short cross bar across it. When the handle rotates and the vertical rod rotates, the water pressure produces bubbles. I also played a game called Mirror Maze, in which there is a white tube, so that you can see that there is no mirror there, so as not to hurt your forehead. As soon as I entered, it was everywhere. I didn't know where to go, which made me dizzy. I entered from the entrance and left from the entrance. also
Science is the source of human happiness, and technology is the ladder of human progress. Xiamen Science and Technology Museum, I will definitely come to experience your scientific power again! Goodbye, Xiamen Science and Technology Museum.

As soon as I entered the Science and Technology Museum, I saw a dazzling array of high-tech products there. There are wonderful, thrilling and educational games such as stepping on hamsters, escaping from danger, playing saxophone by robots and feeling earthquakes. Among them, I like the robot that plays saxophone best. A tall robot, with a gorgeous saxophone in his hand, is playing solemnly, and the beautiful melody is fascinating. There is a screen in front of it with many famous China songs on it. You can listen to any song you want, just press the button. How's it going? Interesting and magical!
What else is unforgettable there? Feel the earthquake? . We walked into a special house, and as soon as the staff there turned on the switch, the whole house shook. At first, I was a little afraid of the scene of the river turning over the river, but I got used to it immediately. However, this exciting scene made me personally feel the harm of the earthquake to human beings, especially reminded me of the way people panicked and fled around during the Sichuan earthquake, and thought of how many people were separated, how terrible it was!
I still like to play? Escape? Games. We sat on the simulated bicycle, pressed the button and the game began. We pedaled our bicycles quickly, swinging from side to side, almost struggling with all our strength. Maybe you'll die if you're not careful? Tiger? Caught and eliminated. Two minutes later? Flying pedal? I finally escaped from the jaws of death, exhausted and panting. From this game, I learned that facing the difficulties and dangers in life requires not only perseverance, but also wisdom.
This visit to Nanjing Science and Technology Museum made me secretly admire: the development of science and technology is really advancing by leaps and bounds! Aroused my enthusiasm for loving and learning science.

During the summer vacation, my father took me to visit the China Science and Technology Museum. I was very excited.
In the early morning of August 4th, we arrived at the Science and Technology Museum by bus. There are many scientific and technological products on display in the Science and Technology Museum, such as recoverable satellite recovery cabin, modern family style controlled by computer, air-powered robot music conductor, dancing robot and so on. There are also many scientific experiments that can be operated by hand, such as billiards, nail beds, stealth, bulletproof vests, stealth planes and so on. Among them, my favorite is the robot stage, directing robots and walking a tightrope.
The music robot that can command is transparent. Can talk, can command the following small robot solo and ensemble, whatever it commands, what instrument will make a pleasant sound. When the music stops, it will introduce itself. It is said that it uses only air as power instead of electricity.
There are two robots on the robot platform. They perform once in a while. They do aerobics first, and then perform unique skills. One robot can tai chi sword, and the other can spin the gyro, and put the high-speed gyro on the blade without falling off.
Another activity I like is tightrope walking. I'm just tall enough to ride. Riding on it, I was not afraid at first. When I ride in the middle of the wire, I always feel that I am going to fall. Later, I rode over without looking down. Why doesn't a bicycle fall when walking on a thin steel wire? That's because there is a heavy object hanging under the bike.
I really want to have fun, but time doesn't allow. I reluctantly left the China Science and Technology Museum. I think if I come to Beijing next summer vacation, I will also go to the Science and Technology Museum. The Science and Technology Museum is really a good place to learn scientific knowledge!

The teacher took us to visit today? China Mobile Science and Technology Museum? . There are many machines in it, such as the one we visited? A little ball trip? ,? Barbie who can dance? ,? Visible electricity? Wait, all kinds of interesting machines.
But what impressed me most was. Laser harp? .
Is it small and exquisite? Electronic harp? Ten strings of red lasers are emitted by laser. I had a strong curiosity when I first saw it. I walk fast, okay? Laser harp? Can't wait to touch the red strings. Suddenly, it made a wonderful, beautiful and long sound, just like the beautiful notes made by playing the piano. It's really nice!
There's another one called. Finger static electricity? what's up Little guy? There are many dots on the screen. I tried to put my hand on it, and the electrostatic index on it was very small, and there was not much reaction. Maybe my fingers are not static. So, I quickly put my hand on the clothes and rubbed it quickly, and then put my hand on it. Static electricity is really getting bigger. It's amazing!
I saw another one? Safety knowledge treadmill? I was about to give it a try when the teacher told us to gather together and left reluctantly because time was limited? Science and technology museum? .
This visit? China Mobile Science and Technology Museum? Although a little sorry, I am still very happy. Those magical machines seem to have brought me into the vast ocean of science. Although I don't quite understand some scientific principles, it makes me interested in exploring science. I am determined to study hard, master more scientific knowledge and make my own contribution to the progress of mankind!
I will never forget this visit.
