During the winter vacation this year, my parents went to Jinan and took me to visit the Jinan Science and Technology Museum.

Arriving at the Science and Technology Museum, ah! Much more fun than I expected. The entire science and technology museum is divided into four floors, each floor has exhibition halls with different contents. Those related to natural science, such as: the gravity of the earth, the eruption of volcanoes, the generation of thunder and lightning, the characteristics of major planets, etc.; those related to mechanical power, such as: models of trains and airplanes, principles of power generation, and principles of wind power generation. etc.; related to high-tech aspects, such as; robot models, video phones, satellite navigation, submarine cables, etc.; and our student paradise, which has computer demonstrations of idiom stories such as "The mantis stalks the cicada, the sparrow follows behind", etc. , very vivid and interesting.

But what excites me most about this trip to the Science and Technology Museum is watching the simulated launch of a manned spacecraft. The entire launch process is the same as the official launch, from the spacecraft taking off, speeding up, and rushing out of the atmosphere. , entering orbit, and returning to the ground, the whole process is like being on the ground. It is also accompanied by photos taken by astronauts in space and some plots of the astronauts' work and life in the spacecraft. They are in almost zero gravity. Do all activities. One of the uncles threw up the flight record book and the pen in his hand. These small objects floated in the spacecraft under zero gravity, unlike the rapid landing on the earth. It was really fun. The aunt who gave the explanation also told us some aviation knowledge, which made us feel that space flight is really amazing. Especially through the explanation of the aunt, I learned that from the "Shenzhou 1" in 1999 to the "Shenzhou 7" in 2008, China has finally achieved the ancient And the dream of the romantic mythical story "Chang'e Flying to the Sky", our country is so great! Our astronauts are amazing! But the launch of the "Shenzhou 7" spacecraft and the Chinese astronauts' spacewalk will serve as a new starting point for our space exploration. I think that by then this beautiful dream will be realized by us!
