This afternoon, I watched the Tiangong classroom with excitement. In the Tiangong classroom, I learned that "space turn", "buoyancy disappearance experiment", "water film tension experiment", "water polo optics experiment" and "effervescent tablet experiment" can only float in the space station because there is no gravity. In space, astronauts can also exercise in space, and bicycles in space can exercise upper and lower limbs. In the past, astronauts could only be carried when they returned to earth. Now there are penguin suits to deal with muscle atrophy and cardiovascular function decline.
I believe that in the future, we will be able to create more space miracles and leave more wonderful China marks in the vast universe.
Looking up at the twinkling starry sky, we can't help but sprout countless question marks. Can people walk normally in the universe? What strange sight will happen when water and effervescent tablets collide in space? Today's Sky Classroom is like a key, which has solved many mysteries for us. In space, Wang Yaping and other three astronaut teachers, like magicians, showed us magical experiments with their hands. Their humorous language and clear context often arouse our admiration. They also showed us "penguin suits", mini refrigerators and other space necessities. Interesting experiments have aroused our curiosity and imagination about space, and we are eager to get more mysteries of the universe.
After reading this lesson, we are more looking forward to space, and my "space dream" is more intense. With the encouragement and blessing of Aunt Wang Yaping, we also understand the great responsibility of contemporary teenagers. We must study hard and make contributions to China's space dream in the future.
The reflection on Tiangong-3 is really wonderful. Our three astronauts in China, Zhai Zhigang, Wang Yaping and Ye Guang Fu, gave us an interesting "Tiangong class". We have seen the wonderful phenomena of object movement under the condition of weightlessness in space, such as "space flip", "table tennis buoyancy disappearing", "water film tension experiment" and "effervescent tablet experiment". Seeing these experiments that can't be completed on earth, I can't help but sigh: space technology has endless mysteries! Our motherland is really great!
Reflection on Tiangong Classroom 4 In that blue space, there is a touch of gorgeous China red, which belongs to the pride of China people.
Today, we watched Aunt Wang Yaping's Tiangong class. Do you know why astronauts' faces look fat? That's because the weightless environment will make their blood distribution different from the ground, and the blood in the lower limbs will swell, so this will happen. There are more amazing things in space! Put ping-pong in a cup full of water. Ping-pong doesn't float on the water like it does on the ground, but stays in the water. This is because buoyancy is produced with gravity. In the weightless environment in space, buoyancy almost disappears, so table tennis can't float. Space is amazing. I want to see more.
Reflection on Tiangong Classroom 5 We just watched the lecture video of Tiangong Classroom, and Wang Yaping and other three teachers gave us wonderful lectures. We watched vibrant biological cells and beautiful water films. At the moment when the blue color is injected into the water film, the water polo becomes bigger and bigger. We seem to see the blue earth. We feel how lucky we are to live on the earth. At the same time, I think I should study hard and try to realize my dream!
At the same time, we also thank the school for providing us with an opportunity to learn. When you grow up, you must arm yourself with what you have learned and serve the motherland! Powerful country has my good boy!
Reflections on Tiangong No.6 Classroom Today, astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu introduced their life in the space capsule to us.
Teacher Ye Guangfu showed us how to turn around in the space capsule. He turned around with his right hand, turned around, and then opened his hands, so the speed slowed down. If he puts his hand on his shoulder, the speed will be faster. After the speech, he introduced us to the difference between the expansion and movement of cells in space and on the earth. Finally, Teacher Wang Yaping made us a transparent water polo. Teacher Wang Yaping first dyed the transparent water polo blue with blue pigment, and then made small bubbles with effervescent tablets.
Teacher Wang Yaping said, "These bubbles are like a person".
Through this class, I found that there are many interesting things in this space. Our astronauts, our motherland, are really great!
Thinking about Tiangong Classroom 7, we sometimes forget that besides the cities, villages, mountains and rivers, the earth where we live, there is also the world in the sky-space.
The world is beautiful. You can see the scenery and phenomena you have never seen before here. You can feel the wonder of floating all over. After watching the Tiangong class, I saw the charm of the space station, and I began to be curious about more things in the universe. I am surprised at things that go against common sense in the natural state of the earth. The spinning gyro and the water polo made of a mirror let me know that I can do so many things without gravity! In fact, the first lesson in Tiangong gave me two biggest feelings: shock and desire for knowledge of the universe, which really refreshed my understanding of the universe. I'm really lucky to see the first lesson in the Heavenly Palace.
Comments on Tiangong No.8 Classroom Today, our whole class watched the live space class together, and several astronauts' uncles and aunts gave us a very vivid science class. The details of astronauts' life in space are public, and the spacewalk, special spacesuit and cell observation in weightlessness … one after another have opened my eyes. What impressed me the most was the various performances of water in the weightless environment in space: without the constraint of gravity, water would become a small drop in space. What's even more amazing is that without gravity, buoyancy will disappear! Like magic, the water in the hands of the astronaut's uncle turned into a water film, a thick water film, and even a crystal ball. It's amazing!
After watching this live class, I felt the magic of space and the charm of science and technology, and made up my mind to study hard and join in the construction of the motherland when I grow up!
Today, the Tiangong class learned how the astronauts of Shenzhou 15 lived in the universe. The daily life of astronauts in the sky. It's completely different from the ground. Take a cup on the ground and fill it with water and put it in a table tennis ball. The table tennis ball will float on the water. In the universe, take a cup and fill it with water. If you put it in a ping-pong ball, it will sink into the cup. It seems that buoyancy is gone. The water that astronauts drink is not ground water, but recycled pure water. The water they drink is actually the same as the water we drink on the ground. Finally, they did an effervescent tablet experiment. Put effervescent tablets into water, whether in the air or on the ground, a lot of bubbles will be released. Astronauts say this water polo is like the earth, it is a cradle.
After watching the astronauts' daily life in the air. Let me understand the hardships and difficulties of astronauts. We should learn more from astronauts.
China astronauts have always been a very romantic group, and they are committed to turning the myth of heaven into reality. The Goddess Chang'e flying to the moon, Yutu is waiting, Kuafu is watching day by day, Beidou is leading the way, Heaven asks fire, and Zhu Rong follows. ...
Today, eight years later, the space class begins again. I was deeply shocked to see the whole course. Children in China have always yearned for space, from the moon to Mars, and from Mars to the sun. I believe that one day, the universe will be full of red flags.
Comments on Tiangong Classroom1120xx65438+At 3: 40pm on February 9th, all the students in Cuiwei Primary School watched a space lecture given to us by three astronauts, Zhai Zhigang, Wang Yaping and Ye Guangfu.
The three astronauts showed their working scenes in the space station, and solved the long-hidden unsolved mysteries of the students one by one. This made the students interested and felt that the questions in their hearts finally had the exact answer. Astronauts also demonstrated many interesting small experiments such as cytology experiment, object movement and liquid surface tension in microgravity environment. Many students sighed when they saw those incredible experiments.
This space lecture not only let us know about the wonderful phenomena in space, but also stimulated students' interest in science and space. Many students say they want to be astronauts when they grow up.
Tiangong Classroom 12 Comments Today, we watched the exclusive live broadcast of Tiangong Classroom in the world, which took us to see the earth from space and appreciate the vastness of the starry sky with an exclusive perspective. Looking at the N opening ways of aerospace science courses, I feel the strong development of science and technology in the new era of the motherland, and feel the mission of my uncles and aunts to integrate patriotism and patriotism into scientific and technological innovation in scientific and technological work. The horn of the new era has sounded, and we are braving the wind and waves in the sea of stars. We should study harder to lay a solid foundation for serving the motherland.
Tiangong Classroom 13 Comments Today, the teacher told us about Tiangong on the big screen, all about space.
It's interesting in a spaceship. Astronauts' uncles and aunts floated around on the spaceship, and the squeezed water swayed from side to side in the spaceship, just like a bright gem. They also told us that our country would launch more rockets to explore the mysteries of the universe. I want to ask: "The astronauts in the Tiangong classroom are floating in the spaceship, but what will they look like when they sleep"?
On the afternoon of February 9th 14 15: 40, my classmates and I watched the space lecture given by the Shenzhou XIII astronaut on the China Space Station. Teacher Wang Yaping showed us some wonderful phenomena in space, such as buoyancy disappearance experiment in microgravity environment, water film tension experiment, effervescent tablet experiment and so on. Seeing the effervescent tablets injected into the water polo, the bubbles produced are so beautiful that I can't help but sigh the magic of the universe!
After reading this lecture on space, I learned a lot, not only about the life of astronauts in space, but also a lot of truth. Science is everywhere, and interesting experiments have filled me with infinite yearning for space.
Comments on Tiangong Classroom 15 after watching Tiangong Classroom. Let me benefit a lot and know the mystery of space: in space, the human body is difficult to rotate, there is no gravity, astronauts can't walk normally, water can float in the air, and even become a "ball" ... The teacher's language is humorous and interesting, which makes me more interested in space, increases the topics to discuss with my classmates, and makes me feel the greatness of my motherland and amaze me. I am very much looking forward to the next Tiangong class, and I don't know what it will bring us.
