Composition Review of Hefei Science and Technology Museum1Aug15th, my mother took me to visit Hefei Science and Technology Museum.
When we entered the gate of the Science and Technology Museum, we saw a large physical model on the first floor. As long as it rotates, the ball will follow the trajectory, pass through various obstacles and return to its original place. I saw along the running direction of the ball that the obstacles were spiral elevators, Archimedes vortex, jumpers and so on. It's a pity that I didn't see the sign about this physical model, and I still don't know its name.
Passing through the first floor, we took the elevator to the second floor. According to my mother, this elevator is called induction elevator. As long as you put your hand on the handrail of the elevator, it will move If there is no one, the elevator will stop automatically. At first, I didn't believe it. I tried several times, and it was all true. Now the technology is really developed! On the second floor, I found a hut that looked as ordinary as possible from the outside, and it said "Tilting hut". It's strange, how can the hut tilt? I can't help but be curious, and I can't help pulling my mother into it. As soon as I entered, I felt that the hut was really tilted and I could hardly stand. I tried to control myself and rushed out. How exciting! Where's mom? "Judy, I can't!" I couldn't help laughing when I heard my mother's words outside.
Later, we visited the third, fourth and fifth floors. Video phone, passive water and maglev train opened my eyes. Modern technology is really amazing. Finally, I watched the dome movie!
The science and technology museum is not only fun, but also informative. I will definitely go there again when I have the chance.
This afternoon, my brother took my mother and me to visit Hefei Science and Technology Museum.
As soon as I arrived at the gate, I found that the shape of the Science and Technology Museum was very strange: the top floor was flat, with a depression in the middle and a big depression below. What a unique shape!
When I entered the Science and Technology Museum, I was first attracted by some drums with no cloth at the top or bottom. I raised my hand and beat the empty drum. I was so surprised that I read the instructions next to it. You can tell at a glance that there is an infrared sensor inside.
Then my brother and I were attracted by two big disks. There is something like a megaphone in front of the big disc. The two big disks are far apart, and my brother and I are standing in front of one. I said something into a megaphone, and my brother actually heard what I said in front of another big plate. I think this may be the same as the game I played when I was a child: the principle of wearing two paper cups into a phone is the same!
Later, we saw a big glass between the two chairs, and a lamp was installed on both sides of the glass. My brother and I sat in chairs and turned on the lights. As a result, I found that when the light was the weakest, I could see nothing. When the light is moderate, I see strange images of my brother and me overlapping; In the strongest light, I only see myself.
There are many strange things in the science and technology museum, which makes me puzzled. What a wonderful world!
