400 words of thoughts after visiting Beichuan Station of Mobile Science and Technology Museum

Last Thursday afternoon, we visited the Mobile Science and Technology Museum. I have never seen anything in the mobile science and technology museum. They have solar generators, bubble machines, sound control machines, and 3D stereoscopic movies. Intellectual puzzles, etc.

I held the human-powered generator, put my hand on the electric board, grabbed the manual lever with my right hand, and turned it hard in a circle. I felt numbness in my hand. I turned it a few more times, and it turned slightly. I felt a little better. After playing with the human-powered generator, I came to the voice control machine again. It was so fun when I played with it. Sometimes I felt like I was singing, sometimes I felt like I was laughing, and sometimes I felt like I was crying. I went to play with the bubble machine again, and when I pulled it and released it, a big bubble came to the surface. I pulled it again, and another big bubble came out. Two big bubbles came to the surface, followed by a small bubble. , like a family. I came to the three-dimensional cinema again, and I saw the three computers, but they were all people, so I had to give up and go play with the solar generator. I pressed the button and the generator started working. There were four small airplanes on it. It flew up all of a sudden, spinning around the pole, and there were two dummies riding bicycles next to it. Of course, they were also solar-powered. The time passed by, "ding---" class was over, and I returned to the classroom.

This visit taught me that we should save resources and cherish everything around us.

============================================ ==============================

On May 6, the "China Mobile Science and Technology Museum" opened in ancient China Area B of Song 1st School has opened. The students were all excited because this was our first time to participate in such an event. The students stood neatly on the playground. There were many leaders on the stage. They also came to participate in the opening ceremony with the students.

The opening ceremony was over, and the commentator took us towards the Science and Technology Museum. Standing at the gate of the Science and Technology Museum, I looked up and saw the words "Science and Technology Exhibition Hall" written in big white on a long bright red cloth. Then, when we walked into the science and technology museum, the commentator told us about the operations and functions of the "obedient ball", "square wheel car", "drawing five-pointed stars" and "color handprints". Among them, I am very interested in a piece of machinery. Its name is "Skinless Drum". When you look at this skinless drum from the side, you can see that it is similar to an ordinary drum, but when you look down from above, you can see that its upper layer There was no skin. I was curious and wanted to figure it out, so I reached out and patted the air in the upper layer of the "skinless drum". Then I heard a "pop" and "dong" sound. I was confused. I figured it out, so I looked up and looked at the instructions for the skinless drum. It turns out that the sound produced by the skinless drum is emitted by the red threads inside the skinless drum. As long as my hand passes over the threads, the sound will be made. I finally Understood. Just when I was preparing to take part in the next machine, the teacher called the students to gather at the gate of the "Science and Technology Exhibition Hall". I realized that the 20 minutes of free activity I had spent all on the "skinless drum", but I I don't regret it, because I know how to operate this "skinless drum". Although I only watched this one machine, I will have the opportunity to watch it in the future and learn more about the exhibits.

I left the "Science and Technology Exhibition Hall" reluctantly. I learned more in the exhibition hall today than I learned in my own science books. I felt that the "Science and Technology Exhibition Hall" had Machines were invented by scientists. The machines invented by these scientists have been praised by everyone. I am determined that from now on, I must study science well and invent various machines. Like the machines invented by scientists, they will be used in all walks of life. It is widely used in various industries.
