I have been to many places since I was a child. Today is my first visit to Shaanxi Science and Technology Museum. My classmates and I went straight to Xincheng Square in the morning. The air in Xincheng Square is particularly fresh, the flowers are particularly gorgeous against the green lawn, and the leisurely pigeons are scattered everywhere in the square, giving people a quiet and peaceful feeling. The Science and Technology Museum is located in the east of Xincheng Square. When I walked into the Science and Technology Museum, I was immediately attracted by this magical world. Its first floor is a model aircraft exhibition hall, and the second floor is an electromagnetic induction exhibition hall; On the third floor is the machinery exhibition hall, with sloping huts, square wheels riding and so on. The fourth floor is the optical exhibition hall; The fifth floor is the do-it-yourself experiment exhibition hall; It's really getting better and better.

Among them, I like riding square wheels best. When you sit in a chair, you seem to be in a virtual world. It's easy to ride with your feet. I see: the ground is flat and you can ride on round wheels. If the wheel is square, you can ride it in an arc. It's amazing!

I also like the inclined cabin, because the cabin is inclined, so it is called the inclined cabin. As soon as I walked in, I felt dizzy and uncomfortable. This is because your brain realizes that the hut is tilted, because the lines you see with your eyes tell your brain that the house is positive, while our other sensory organs feel that the real hut is tilted, which reflects the contradiction of information in the brain, which makes our balance system at a loss and makes us feel dizzy.

In addition, I also did a very interesting little experiment-eggs and salt water. First, I put the eggs in a bottle with half a glass of water. What do you think has changed? It was found that the egg not only sank, but also doubled in shape. Isn't it wonderful? Put half a glass of water into another B cup of the same size, drop a few drops of red ink, and then add salt to the red water. When the water in the B cup does not melt, take a funnel and slowly pour it into the A bottle. At this time, the water is half white and half red, and the red water is below. Put the eggs in because of the salt. A wonderful thing happened: the egg floated, and then stirred with a wooden stick, and the egg floated higher.

After visiting Shaanxi Science and Technology Museum, I understand that there are many miracles in the world, and there are many things waiting for you to discover and explore. Now I will study hard, lay a good foundation and solve the mystery of this unknown world when I grow up.
