This afternoon, our whole class went to Xidu Primary School to visit the exhibition of the Mobile Science and Technology Museum. The students talked and laughed all the way, and I was very excited. I didn't know there would be those interesting things.
We arrived after a short walk. As soon as I entered the gate of the Science and Technology Museum, I was shocked by what I saw-it was so mysterious! I think the strangest thing is the "ball screen cinema". It's very big, bigger than two elephants combined. It's a hemisphere, gray, and inflatable! At this time, what films will be shown in the dome theater has become a hot topic for everyone. Some say they will show horror movies, some say they will show comedies, and some say they will play back animations ... Everyone is talking noisily. After a while, Ceng Laoshi said, "OK, let's go in." As soon as the voice fell, we squeezed in one by one, sat down in a random place and started watching movies. The name of this film is: the mystery of dinosaur extinction. No sooner had the movie started than a fierce dinosaur rushed at us with its jaws open. The timid students began to scream, and the courageous ones dared not look directly at the big dinosaur. Then, the film introduces us: pterosaur, brachiosaurus, long-necked dragon and Mamenxi dragon. But at this moment, the camera suddenly turned to outer space. What's going on? It turns out that an asteroid is about to hit the earth! After the asteroid hit the earth, it produced the force equivalent to 1, atomic bombs, and the dinosaurs disappeared from the earth.
After the movie, we went to watch the robot show.
The first robot is called Xiaoyou. It can both sing and dance. It danced briskly to the music. After the performance of "Xiaoyou", the students were amazed again and again. Next is the performance of a small humanoid robot. It's very capable, it can stand upside down, the eagle spreads its wings, the golden rooster is independent, and it can also tune the machine dance! After its performance, the students were full of praise for its performance.
after watching the performance, we went to play with some machines and models. I played: acoustic standing wave, symmetrical face, light path ... After playing, we reluctantly left.
This visit has taught me a lot of knowledge. I am so happy that the technology of my motherland is really developed!
2. An interesting film composition
I have long heard that 4D movies are very interesting. I have been asking my father to take me to see them. Today, my father finally granted my wish.
as soon as I walked into the 4D cinema, I felt it was different from other cinemas. Its hall is smaller than the ordinary cinema, and it is semicircular. There is a 18-degree circular metal screen in front, and there are many small holes in the ceiling for spraying water.
There are not many seats in the hall. They are arranged in pairs, and they are also made of metal. Each seat has a seat belt and a pair of handrails on both sides. If you hold it with your hands, it will be like flying an airplane. There are also several small holes in the handrails, which are specially used for air jet, and there are two plastic wires under the seat. The name of this 4D film is A Journey to the Cretaceous.
I was nervous and excited when the film was about to show, so I struggled to climb into my seat, fasten my seat belt, put on my three-dimensional glasses and hold the armrest with both hands. The movie started, and several huge dinosaurs came to me. Every step of them was powerful, and the ground was shaken, and I swayed from side to side.
after a while, a pterodactyl flew in the air with a dinosaur egg in its mouth, and I rocked up and down with it, as if I were also a flying pterodactyl. Inadvertently, the dinosaur egg fell into the deep sea from the pterosaur's mouth, and immediately some water really spilled, just like I fell into the sea myself.
Suddenly, two big pythons came. They spit out terrible tongues, "Boo, Boo", and my hand was sprayed with real gas, just like the pythons really came. At this time, the asteroid hit the earth, all the dinosaurs fled around, and I was shocked, as if the end of the earth was coming ... The movie was over, and my father and I left the 4D cinema with reluctance. Alas, such a beautiful and interesting movie was a little short, but I haven't enjoyed it yet.
3. Write a composition of 6 words about visiting Dongguan
Today is Friday, and we finished the mid-term exam on Thursday and Friday, so the school organized us to travel.
There are two tourist routes: Chimelong Happy World and Dongguan Science and Technology Museum. I heard that Dongguan Science and Technology Museum has ball screen movies and 3D
movies to watch, so I decided to go to Dongguan Science and Technology Museum.
After three hours' running, we finally came to the spectacular Dongguan Science and Technology Museum.
In Dongguan Science and Technology Museum, the first thing that caught our eye was the 3D cinema, so we wanted to see the 3D movie, but the movie had already started playing
. Well, we'll have to see it ourselves next time.
let's go down to the first floor to see the enlightenment technology. There is a glass ball like a crystal ball with electricity in it,
but the electricity is harmless to human body, so when you put your hand on it, the electricity will be concentrated in your hand
without hurting you. Then we went to play with a square wheel car. As the name implies, a square wheel car is a car with square wheels.
While we were having fun, we suddenly heard a loud noise, and then heard the creaking of high-voltage electricity, and then
a lot of smoke came out. Is it because the machine there is out of order and is about to explode? I can't help thinking, the
thought of "run for your life" flashed through my mind. Where is the exit? I can't find it! This is a dead man! At this time, I found that others not only
did not run for their lives, but also gathered in one place motionless. Did aliens control them? So, I also
walked over there. Oh, it was an experiment. What a false alarm. They put a magnet
the size of a computer mainframe in the middle of a power grid full of high voltage electricity, and all the electricity was absorbed by the magnet, haha! That's funny.
Then we went to see many interesting experiments and played many interesting things.
finally, we took the bus and went home.
4. Adventure of Orient Mountain Water Theme Park in Shaoxing World Ballscreen Cinema Composition 45 words
6 words of swimming in the water park
Today is the third day that my two brothers and I came to Chengdu. The three of us had planned to go to the beautiful water park the night before. I chose water because it was too hot, and I went there to feel the coolness of the water. I didn't sleep well all night for this matter, so I woke up my brother from his sleep early in the morning. After breakfast, we went straight to the water park. When I arrived at the "National Scenery", I saw it. Wow, it's so beautiful and bright! A castle comes into view. The blue pool, clear water and rippling streams are the "river protection" of this castle, which surrounds the castle and makes me dizzying. We first came to "Huhe", rented a rubber raft and floated down the running water. At this moment, the walls on both sides had water outlets, and the raft was almost knocked over by the current at this end. Fortunately, my brother grasped the balance in time, otherwise it would fall on all fours, which made us laugh.
further inside, we found the wave pool and couldn't wait to walk in. I took my two brothers by the hand and walked over. At the beginning, the pool was shallow. The deeper the water went, the deeper it became. We stopped at the chest-high water. At this time, the pool was already crowded and yellow. Do you know why it was yellow? Because we're all wearing protective clothes. The host began to count down
"1. 9。 8。 7。 6 ..... ",suddenly a wave came in and knocked me upside down. Before I stood firm, another bigger wave threw me up, and then a small wave came running towards me. After about < P > ten seconds, an imposing wave came. It came straight to the shore like an aggressive army, and many people could not resist being washed to the shore. How exciting! With the surge of water, people in the pool cried and danced happily. This is really interesting. We feel the coolness of the water here and get a good harvest.
One day has slipped away quietly, and we should say goodbye to this place, goodbye to the water park!
5. How to write an autumn tour composition of Jurassic dinosaur park in Nanjing Science and Technology Museum
Last Friday, the school organized us to go to the Science and Technology Museum for a spring tour.
Nanjing Science and Technology Museum is located in the south of Yuhuatai, covering an area of about 3, square meters. The main pavilion is a dome-shaped building surrounded by a small pond, which looks like an island. There are two hemispherical buildings in its southeast, namely the ball screen cinema and the 4d cinema.
we first came to the dome theater, whose screen is 21 meters in diameter and tilted 3 degrees. It seems to make people feel floating in it. Here, we watched a film called African Elephant Kingdom. This paper mainly tells the story that the matriarch in the elephant kingdom led everyone to find food and water during the drought, and finally ushered in heavy rain. Because most of the walls of the ball screen movie are screens, everyone is there when they are lying on it. Especially when two male elephants were fighting, one rushed to the other, but I clearly felt that he was rushing towards me, scared and hugged Jiang Hongyu, but his eyes were still "glued" to it. At this time, I only heard screams around me. The movie is over, and I'm still immersed in that wonderful feeling.
then, we went to the main hall. There are many interesting things: Holography, time tunnel, Labyrinth, virtual soccer. . However, my favorite is the maze. Seeing this, you may think: What's interesting about the maze? Don't worry, the maze I'm playing is made up of mirrors. When I first entered, I thought to myself: What's so difficult? ! I'll be out in a minute. But when I took a few steps, I found that it was not that simple: I walked a few times, and I couldn't understand the southeast and northwest at once, and I didn't even know where I came from. I often walk and bump into the mirror. I hurried back and walked for a while, and I was happy at once, because there was a road ahead, so I could take a closer look. Alas, it was still a mirror. Finally, I finally came out. Looking back at the maze, he sighed, "This little mirror is so big. Afterwards, we played many interesting things. I didn't leave until I had dinner.
I want to come here again next time!
6. Introduction of the dome movie
The dynamic dome movie hall adopts 7mm projection equipment, and the diameter of the hemispherical screen is 18m. When the audience watches the movie, the whole picture is covered with spheres, but they can't see the edge of the screen. The transmission metal screen and six-channel stereo effect make the audience enjoy the varied and vivid weather. The dynamic platform in the cinema is a high-tech system engineering integrating hydraulic pressure, electrical automation control and computer animation. When you sit on the platform carrier, the whole carrier can lift up and down, tilt left and right, pitch back and forth, so you can simulate a spacecraft to invite you to visit space, or a submersible to enjoy the strange scene of the underwater world. With the vivid pictures and the activities of the platform carrier, people can't help but enter the role, resulting in a very real and thrilling special feeling.
Dome film is a kind of film with dome screen, also called "dome film". Its dome-shaped screen is developed to the limit of wide screen and then to the sky. It covers the audience like a big iron pot. This dome-shaped screen was originally semi-dome-shaped. In 1939, at a World Expo held in new york, people used five projectors to project huge composite pictures on the dome-shaped screen. At that time, people who saw this kind of film were amazed. In World War II, some countries once projected the image of enemy planes on this dome screen for air defense training. It only developed into a full dome shape in the 197 s. Dome-screen movies mostly adopt single-camera shooting and single-camera projection. A 65mm or 35mm camera with fisheye lens is used for shooting, and a 7mm projector with fisheye lens is generally used for projection. There is a cinema dedicated to this kind of film. The screen is shaped like a dome, with a diameter of 25 meters and a height of about 18 meters, which extends to the back of the entire audience, as if half a huge ball cover was on the ground. The audience went to the "ball" to see the movie through a special tunnel. On this peculiar screen, movies about interstellar travel and Apollo spacecraft landing on the moon have been shown, and the effect is particularly good. There are several dome-screen cinemas in China, the most representative of which is the dome-screen cinema of China Science and Technology Museum, which was completed in August 1995 with a screen diameter of 27 meters and 5 seats. The films that have been shown are American 7mm films "Grand Canyon" and "Flying into Space".

I took a bus to the Science and Technology Museum again. Last time, we went to the Science and Technology Museum and saw many interesting things. This time, we went to the Science and Technology Museum and saw many interesting things. I saw dinosaur fossils, which are dinosaur bones. I saw dinosaur fossils. The dinosaur's head is small, its body is big, and it has bones. Its body is as thick as an elephant, and its bones are very sharp. Our children are all born.

The narrator uncle explained to us the composition of dome screens, and there were six of them.
The movie begins. It says that there are a group of sharks on cocos Island, and there are many migrating fish. Sharks only eat injured fish and fishy fish. Once, sharks were going to eat fish. They herded the fish together, and the school of fish hung like a tornado. The sharks ate all the small fish effortlessly, leaving none.
