In daily study, work or life, everyone will come into contact with composition more or less. Composition is a narrative method that expresses the meaning of a theme through words through human thought consideration and language organization. So how to write a good composition? The following are 7 compositions from the fourth grade of the Shanghai Science and Technology Museum that I collected. Welcome to read and collect them. Shanghai Science and Technology Museum Fourth Grade Composition Part 1
The heat is unbearable, but it still cannot resist my yearning for the Shanghai Science and Technology Museum. On July 20th, our family took the high-speed train to visit the famous Science and Technology Museum in Shanghai.
The exhibition halls in the Science and Technology Museum are dazzling, including the Earth Hall, Spider Exhibition, Animal World, etc., but the one that makes me linger the most is the science and technology exhibition.
The science and technology exhibition mainly explains the changes, reforms and modern high technologies of human science and technology. I looked at the "Human Technology Change Zone" carefully. My body remained motionless, as if my soul had left my body. After reading it, I was shocked. It turns out that human technology changes so slowly! From the initial clothes made of animal fur to the current clothes made of elastic fiber, there have been several evolutions in between! I quickly took a photo. Record this "significant discovery".
Going further back, we saw the words "Modern Technology Exhibition Area", and we knew we were in another area. Here we mainly talk about 3D printing technology. However, this 3D printer cannot print 3D things out of thin air! 3D printing requires layout, and the layout must be completed on a computer. The computer and the large screen need to be connected by a data cable, and then a conductive cable is used to connect the machine. How to do it? To make a template in the computer, the large screen is decomposed three-dimensionally to deduce the effects on other surfaces. Finally, the materials are prepared and wait for the 3D printer to produce it.
After a general understanding, my father discovered another activity: "3D polishing", which is to 3D print photos in glass. We thought it was quite interesting, so we gave it a try. I took a photo first, and the staff uploaded the photo to the big screen. I was surprised to find that there were many more lines on my face! The staff member said to herself: "The degree of completeness is pretty good." Then she pressed another button, and the machine next to her started working. It fired many lasers and carved little by little. Before long, it was done.
In the afternoon, I was going to the Old City God Temple, so I had to leave. This time, I "returned with a full load". Shanghai Science and Technology Museum Fourth Grade Composition Part 2
Last week, my aunt and cousin and I went to the Shanghai Science and Technology Museum.
Wow! The Science and Technology Museum is so big, with a large square in front of it. There were many people selling things in the square, most of them selling novel small toys. I was immediately fascinated by the chickens, birds and other toys woven from bamboo splinters. A few bamboo splinters could enchant the little animals. The editing was so lifelike, so amazing!
My aunt took us to the ticket office quickly. There were several long lines of people waiting in line to buy tickets, and my aunt became the tail of the dragon. My cousin didn't want to waste this time in vain. He was playing and waiting in the pool in front of the door. I picked up the water with my hands and threw it at my cousin. Not to be outdone, he picked up the water and hit me back. Haha, we both became drowned rats! At this moment, my aunt bought the tickets. We quickly dried our hands and ran into the Science and Technology Museum impatiently.
We went to the animal area first. There were lifelike animal statues of different shapes. I didn’t dare to blink for fear that I would miss something if I blinked. Suddenly, my cousin screamed. I followed his gaze and saw, ah, a huge spider web was above our heads! A black spider looked at us eagerly. I was startled and pulled my brother forward. run. Then we came to the Bat Cave, where hundreds of bats were lying quietly on the walls of the cave. All visitors walked slowly and slowly for fear of shocking them. After carefully walking through the bat cave, a colorful world greeted us! Butterflies with bright colors, some were about to fly, some were about to dance, and some were resting... I happily walked over, opened the video, and watched Introduction, then I know: Don’t be attracted by the bright colors of butterflies. The brighter the colors, the greater the toxicity.
Oh! These are some "poisonous beauties"!
The Shanghai Science and Technology Museum opened a window to the palace of science for me. My scientific dream will start from here. Shanghai Science and Technology Museum Fourth Grade Composition Part 3
It’s holiday, and we came to the Shanghai Science and Technology Museum with great joy. Go see the advanced and advanced science and technology and learn rich knowledge.
In the Science and Technology Museum, there are robots built with wonderful computers. For example, the smart robot that can play backgammon. When I had three pieces connected together, the robot hurriedly blocked it, and its intelligent mind made me ultimately fail. Another inconspicuous robot has developed a "good arrow" skill, and every shot hits the target with perfect accuracy. Not to mention the robot "Robert", who is the famous host of the robot theater. It has witty lines and is very popular with the audience.
After talking about electronic technology, next is the interesting genetic technology. In order to create more animals and plants, scientists extracted the reproductive genes from animals and plants, and successfully cloned cloned sheep and cloned plants.
The animal world is children’s favorite place. In the bat cave, we learned that bats rely on ultrasonic waves to catch bugs. Once the ultrasonic waves bounce back, it means there are bugs in front, and the bats will fly over and eat the bugs. In the animal exhibition hall, there are also beautiful butterfly specimens, huge and heavy tortoises, lizards living in the tropics, and colorful, varied and colorful birds. The variety of animals here is really dazzling.
The Shanghai Science and Technology Museum has brought us knowledge and joy. This time I came to the Science and Technology Museum, I gained a lot, and I look forward to coming again! Fourth grade composition of the Shanghai Science and Technology Museum 4
Today, we are going to the Shanghai Science and Technology Museum, although the weather is cloudy It was heavy and drizzling, but we did not let the sudden change in weather ruin our mood
Early in the morning, I happily ran to school carrying a bag of snacks. At around eight o'clock, we set off. Along the way, the students were talking and laughing, some were singing, some were guessing riddles, and some were playing games. They were all very excited! At nine o'clock, we arrived at the Shanghai Science and Technology Museum. As soon as we got off the bus, we saw a modern building standing, which was very spectacular. The building is concave in shape, with a large sphere with a transparent glass curtain in the middle. The entire architectural style is unique, with an asymmetrical structure that is low in the west and high in the east, which is eye-catching. "This is the Shanghai Science and Technology Museum, so majestic!" Everyone couldn't help but admire it. Entering the museum, we first entered the animal world. As soon as we entered, we saw huge elephants and ferocious leopards. Look, a group of small Tibetan antelopes were eating grass with relish. When we stepped on the elevator, we entered Spider Exhibition, this is, I thought: Spiders are so scary, so disgusting. However, as soon as I entered the door, I saw a spider. It had round eyes and a small mouth. It was so cute. This way my fear of spiders disappeared. Then, we went to explore the earth's crust and saw many unknown things, including pearls, seismometers... We also walked on the rope bridge, which was shaky and thrilling! At around 2:10, we reluctantly left the Shanghai Science and Technology Museum!

The winter vacation has begun, and my mother took my aunt and my family to the long-planned trip to the Shanghai Science and Technology Museum. In the early morning, my aunt drove to pick us up. I was very excited along the way. When I arrived at Ningbo Railway Station, I bought the high-speed rail tickets and we set off. The high-speed train is so fast. It only took us two hours to arrive at Shanghai Hongqiao Railway Station.
We checked into a hotel near the Bund and had a rest. The night view of the Bund outside the window was so beautiful, with bright lights, numerous high-rise buildings, and the eye-catching Oriental Pearl Tower was particularly bright. Early the next morning, we took Metro Line 4 to our destination—Shanghai Science and Technology Museum. I saw that the Shanghai Science and Technology Museum was like a huge crystal castle, which greatly attracted my attention. I couldn't help but exclaimed: "Wow, it's so big!" I couldn't wait to hold the hand of my good friend Zhang Haojie and ran quickly into the science and technology museum.
We first went to the Robot World exhibition area. As soon as we entered the door, a red and white robot like "Optimus Prime" came into my eyes. It is mighty and majestic, as if it is ready to fight the "Decepticons" at any time. "Wow!!" Following Zhang Haojie's exclamation, I immediately ran over and saw three mini and cute little robots dancing together. They stretched out their hands to say hello to us, and twisted their waists to show us With its flexible and soft body, I deeply feel the progress of science and technology.
Then we went to the zoo again. What intrigued me the most was the spider exhibition. There were many spider specimens of different shapes which opened my eyes. I saw a huge Tarantula spider weaving a web quickly. I looked at the introduction to the knowledge section next to it and learned that this spider likes open, dry places where it can bask in the sun, and it is very cunning. It likes to hide itself in some grass, and when the prey passes by, it can unexpectedly give the prey a fatal blow. At this time, Zhang Haojie shouted: "Tingting, come here and take a look, there are real spiders here!" I looked out curiously! Wow, I saw only a few real bird spiders placed in a breathable glass box. I excitedly opened a corner of the drawer, and a small bird spider crawled over alertly. Its legs were covered with fine hairs. , a pair of eyes the size of sesame seeds looked at me maliciously, as if ready to break through the box and pounce on me to bite me. We went to the third floor to visit Crust Quest, Light of Wisdom and Rainbow Paradise. We saw cloned sheep and enjoyed the food tour. We had a great time!
Unknowingly, it was afternoon and we reluctantly left the Shanghai Science and Technology Museum. I learned a lot of knowledge during this visit and broadened my horizons. It was such a happy day! Shanghai Science and Technology Museum Fourth Grade Composition 6
This morning, my parents took me to visit the Shanghai Science and Technology Museum. When we arrived at the Science and Technology Museum, we first went to the Animal World on the first floor. There are so many animals in the Animal World. Eagles, lions, leopards, sea lions, tigers, and polar bears are so much fun. In the spider world on the second floor, there is a microscope. Through the microscope, you can see a very small spider. There are many spiders shut in glass cabinets. When I was about to look, I suddenly saw a spider on the spider web in the sky. The moving fake spider scared me.
We are in the robot world on the third floor again. The robots there can play the piano, some can compete with people in archery, and some can also do exercises and dance. Among them, there is a person singing a chorus next to the robot playing the piano. We also looked at how to make a robot, who invented the robot, what other acrobatics the robot can perform, and what other uses it has. On the third floor, I also queued up to play boxing and cycling.
On the fourth floor, we visited the aerospace technology exhibition, which contained artificial satellites and rockets. I also watched a giant-screen movie and learned about the planetary world, how the earth was formed, how the sun was formed, how the Milky Way was formed, and that there are more distant universes outside the Milky Way. We must study hard now and explore when we grow up. Shanghai Science and Technology Museum Fourth Grade Composition 7
The Shanghai Science and Technology Museum is a place I will never get tired of playing. There is a wonderful light of wisdom, a childlike rainbow paradise, and a mysterious world of robots. ...What I like most is all the living things.
When I first entered the gate, my eyes were lush and lush, as if I had entered a primeval forest. A huge creature stood there. It turned out to be an African elephant. I saw its ears like cattail leaf fans, sharp teeth like daggers, and a long gray and white nose that stretched all the way to the "sky". An adult standing next to it only occupied one-third of the space. There are also ferocious cheetahs and lions hidden in the forest. They open their bloody mouths as if they want to swallow the whole world. Looking over there, a tiger is bending over, eyes wide open, extending its sharp front paws, about to catch the deer in front of it, while the deer is curled up and trembling... Everything in this primeval forest shows the nature The most realistic aspect of , but also daunting.
Look here again, what a lovely and harmonious animal world! Our national treasure pandas are living a peaceful life.
Some of them are carefully walking in the bamboo forest, some are chewing bamboo with relish, and some are sitting on the ground and sunbathing... On the hillside, sika deer, goats, and baby zebras are all enjoying the beautiful days freely. Going further, we arrived at the North Pole unknowingly. Everything was white, and under the heavy snow, polar bears and little snow foxes were squatting on the icebergs and looking into the distance!
After watching all the biological phenomena, I also watched a dome movie, tried to play chess with a robot, and learned about the methods of information transmission. The rich game projects and unique scientific principles of the Science and Technology Museum opened my eyes!
