There must be a lot of feelings after reading a certain work. It's time to write a review and record it. So what should we write? The following is my feedback on the Tiangong class for your reference only. I hope I can help you.

Review of Tiangong Classroom 1 "Astronaut", a great and sacred career, must be completed by an extraordinary person! The teacher on TV showed us that their movements in the space capsule were very light. One of the male teachers sat in the air with his feet up. As long as his hands are open, his whole body will rotate. But once the hand is closed, the speed of body rotation will slow down. I wonder, if he holds a fan and fans it to one side, will it speed up the rotation? How do astronauts drink water in the air? Is their water the same as that on our earth? In fact, they drank the same water in space as we did. However, the way they drink water is completely different from that on our earth. They have a special bag for drinking water. When he pinched it with his hand, several big water polo balls would slowly emerge and float in the air. At this time, they just need to eat these big water polo like snakes and drink water. Astronauts need to overcome all kinds of difficulties in space. Their persistent spirit and positive and optimistic attitude deserve our study and praise!

Looking forward to it, looking forward to it, the "Tiangong Classroom" will finally meet us. The program moved the class to China people's own space station, and three astronauts in the core module of the sky gave us a unique "space lecture".

I want to be a people's teacher when I grow up, because my classmates have too much homework now, and I cry silently because of my homework where my parents can't see it. It is said that people have three sufferings: studying, driving horses and grinding bean curd. Now reading is more bitter than before, so in the future I want my classmates to really "lighten the burden" and make the flowers of the motherland smile more brightly.

In spring, I will take them out for a spring outing, enjoy flowers and play games. In summer, we sit under a tree and talk. In autumn, let's go and see how the leaves fall. In winter, we have snowball fights and make snowmen together.

Students, the ideal is not a fantasy, we need to pay practical actions, come on, let's create a better tomorrow together!

My speech is over, thank you.

Comments on Tiangong Classroom 3 Today, I watched the first space class on my mother's mobile phone, which was particularly interesting. Let me tell you about it! The first one is a young astronaut, uncle. He taught us how to keep stability in space. First of all, when we are unstable, there are many handrails on the spacecraft. What are these handrails for? They are when you are unstable, you can grab them casually, so you won't fall back and forth!

The second is an aunt, who picked up a small stick like two drops in the water. On a nail, he became a round and big water drop, and the astronaut's aunt dropped many drops in it. It's getting lower and lower, and it feels like it's breaking. Then, a miracle appeared. Aunt, holding a beautiful flower in the center of the water drop, suddenly the water drop came over, like a windmill, so beautiful! Then the astronaut's aunt put the blue pigment in the water and covered it with yellow leaves. It's strange that he suddenly became like the earth!

The space world is really interesting! what do you think? I want to be an astronaut in the future.

On Thursday, my classmates and I watched the China Aerospace Tiangong Class. The astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu of Shenzhou XIII turned into "space teachers" and gave us a very lively and interesting lesson. Astronauts have conducted many space experiments: "space fitness", "cell culture" and "buoyancy loss". Among them, what impressed me was a series of experiments on water made by Wang Yaping astronauts. Due to weightlessness, water in space presents a wonderful phenomenon completely different from that on the ground. In the water film tension experiment, the folded paper flowers rotate on the surface of the water film and slowly bloom, which is simply beautiful! In the optical experiment of water polo, air is injected into the water polo to form a round bubble, and the mirror image in the water polo and the round bubble is actually a positive and a negative! In the experiment of effervescent tablets, after pigment and effervescent tablets are added to the water polo, many bubbles are quickly generated in the water polo, which gradually becomes a "blue water polo", just like our earth. How amazing!

Through the Tiangong classroom, I not only learned wonderful scientific knowledge, but also felt the power of science and technology. The rapid development of China's space industry, the establishment of space station and the realization of flying dreams all depend on advanced space science and technology. Looking up at the starry sky, I will work harder to learn scientific knowledge and contribute to the future development of science and technology in China.

Today, the teacher organized us to watch the Tiangong classroom. I went to see the Tiangong classroom with great expectation and felt the space life for the first time. I'm very excited.

First of all, I saw that they didn't use our ordinary cups when drinking water, but used a bag with a straw on it. I also found that they didn't drink it at first, but squeezed the water out first. Water can float in the air, and you can drink it into your stomach with only one mouth. I learned that everything is floating, because there is no gravity in space.

Subsequently, they used the tension of water to make water in the water film into water balloons. The experiment of convex lens imaging was explained to us, which made us understand the imaging principle of convex lens inversion.

Through the study of this Tiangong class, I learned a lot of space knowledge. Their spirit of daring to explore deserves our admiration! I will study hard and use my scientific and cultural knowledge to contribute to the aerospace industry of the motherland in the future!

I heard that Shenzhou 13 has returned, and it will be broadcast live to us today.

In the live broadcast, we were told many scientific principles. For example, put a bottle full of water on the table, then put the ping-pong ball in it and stick it in with a straw. It's amazing that the ping-pong card didn't pop out inside. Then he opened the bottle full of water. It didn't spill, but floated up without leaking a drop of water.

There is also a magnifying glass on the table, and then the water is squeezed up with a water squeezing bag. The squeezed water does not overflow, but solidifies on it, as if living on it. In this way, it becomes a big crystal ball. Then I made a circle on it. You can see there are two astronauts on the circle. One is straight and the other is upside down. It's amazing.

After watching this live broadcast, I feel the magic of science and the strength of my motherland, so I will study hard so that I can contribute to my motherland.

Comments on Tiangong Classroom 7 Shenzhou 13 returned to Earth, bringing us a live broadcast.

I learned a lot of useful scientific tips during the live broadcast.

In space, put a cup full of water on the table, then put the ping-pong ball in it and insert it into the water with a straw. Table tennis is really great. It doesn't pop up, it's fixed. Pour out the cup full of water. The water and ball in the cup didn't pour out, but not a drop leaked out.

Another scientific coup is to put a magnifying glass on the table and then squeeze water from the squeezing bag. The squeezed water will not overflow, but solidify on it, like a big crystal. Then form a circle on it. You can see two astronauts on the circle. One is straight and the other is upside down. It's amazing.

After watching this interesting video, I felt the magic of science. We should study hard and try to be a scientist.

Comments on Tiangong Classroom 8 I watched Tiangong Classroom broadcast by China Space Station. Strange scenes and wonderful experiments made me feel at a loss. When the ping-pong ball in astronaut Wang Yaping's hand no longer floats on the water surface but melts in the water, when the water film slowly turns into a water polo and air is injected into it to become a double ball, it makes me feel wonderful! The buoyancy knowledge I just learned in science class, through a vivid and interesting comparison experiment between heaven and earth, let me know that there are more wonderful knowledge waiting for me to discover in the world, which makes me have a strong interest in aerospace science.

Watching the "Tiangong Classroom" ignited my space dream and curiosity to explore the mysteries of science, and stimulated my interest and enthusiasm in learning science. Let's get close to space, understand space and love space, and further stimulate our yearning for space and enthusiasm for learning scientific and technological knowledge. By studying hard and mastering scientific knowledge, I will make my own contribution to the scientific and technological development of the motherland in the future.

On February 9, I watched the Tiangong class. During the 60-minute course, the astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu of Shenzhou XIII explained the knowledge about space to the people of the whole country in the space station in China. This is the first teaching activity of China Space Station, and it is a feat of China's space industry, which indicates the superb manned space technology of China and that we can learn a lot of unprecedented knowledge about space.

Astronauts in the space station introduced their usual residence, space cytology research, space turn, table tennis buoyancy disappearance experiment, water film tension experiment, water polo experiment and so on, and explained the scientific principle behind the experiment.

Behind every step of innovation and breakthrough in space travel, it is inseparable from the hard struggle of generations of astronauts, which is what we call "space spirit."

"Flying dreams never lose weight, and scientific dreams have unlimited tension." Just as Wang Yaping, a female astronaut, said before going out to war, as long as we dare to dream, pursue dreams and build our own dream spaceship with wisdom and sweat, we will certainly be able to greet the launch moment of our dreams and fly to our own vast starry sky! As a middle school student in the new era, I should cherish the present, seize the opportunity, study hard and make unremitting efforts for a better tomorrow from now on! Add luster to the future development of the motherland!

Comments on Tiangong Classroom 10 This afternoon, students in this campus of Cuiwei Primary School had a special "live class"-"Tiangong Classroom".

Today, the teachers teaching in the "Tiangong Classroom" are three special-grade teachers. They are three astronauts in Tiangong-1-Wang Yaping, Zhai Zhigang and Ye Guangfu. Three astronaut teachers showed us the magical experiments in space, which was refreshing. In space, the phenomenon that used to be very common on the earth has completely changed: the floating ping-pong ball is no longer floating, but quietly immersed in the water, and the origami flowers are completely adsorbed on the water film. ...

The students were deeply attracted by these strange phenomena. Why do these phenomena happen in space? What is weightlessness? What is it like to walk in space? This spectacular Tiangong class aroused heated discussion among the students and made them interested in space exploration and scientific experiments. What a touching lesson!

1On the afternoon of February 9th, we watched a "live teaching" recorded by China Space Station, which was explained by Shenzhou XIII astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu.

Astronauts introduced us a lot of equipment they needed for their lives and answered many questions in this regard. There are "penguin suits" to prevent weightlessness, cardiac muscle cells that beat in weightlessness, and turning around in space without the help of handles. Of course, among them, I am most interested in the experiment of effervescent tablets.

As we all know, effervescent tablets will produce a lot of bubbles if they are put into water, so what will happen in space?

In this class, "space teacher" Wang Yaping will solve this problem. First, she took out the weightless water polo she had prepared before. To be more obvious, Miss Wang added blue ink to the water polo. As half an orange effervescent tablet was stuffed in, a wonderful phenomenon appeared: the water polo became swollen, full of bubbles and gave off a charming fragrance. I am deeply immersed in this wonderful experiment.

But time is always short, only a short time, astronauts will say goodbye to us, but I still have many problems to explore, so I must study hard and try to put on my spacesuit to study when I grow up!

Comments on Tiangong Classroom 12 I was greatly shocked by this watch. I know my motherland is very strong, but I didn't know there were so many countries in the world. It is no longer a rocket but a space station, no longer a trip to the moon, but a space exploration. Teacher Wang Yaping said, "The future belongs to us and our generation."

In the process of teaching, I was fascinated by the experiment of effervescent tablets and water polo. Teacher Wang made a water polo first, and then added blue paint to it. Water polo became romantic in an instant. Isn't this the earth where we live? Then add effervescent tablets and the water polo will boil slowly.

"Do the stars you see when you sleep blink?" A little girl asked innocently. This little problem, I feel every child's desire for space. Many years ago, our ancestors became interested in the universe and wanted to travel in space. Now this dream has been realized by people in the new era.

I can't help sighing in my heart: our motherland is no longer the sheep that is slaughtered by others, but the eagle that flies between heaven and earth!

Tiangong Classroom 13 Comments Do you know anything about astronauts? Maybe you don't understand, there is a video showing the life of astronauts in space. Let's walk into this video!

In this video, three astronaut teachers showed us the magic of space. They did an experiment, which was amazing. On earth, it will float into the water, but space is different. First, press the ping-pong ball to the bottom of the water with a pipe, then release it, and the ping-pong ball will sink to the bottom. Another astronaut teacher threw the bucket of table tennis on it, and didn't drop a drop of water.

The astronaut teachers did another experiment, which was even more magical. First, they took out a mold. Then they filled the mold with water. An astronaut teacher added more water, and it turned into a big ball. The most amazing thing is that when another astronaut teacher took a syringe and injected small water droplets into it, the small water droplets were completely intact after entering the big water droplets, and none of the water in the big bubbles fell.

Space is really amazing!

What is the reason for reviewing in the Tiangong class? 14 failed. Light and dark, who can be the best? Feng Yi just likes it. How did you know?

Man has begun to explore the universe. Today, we watched the astronauts of Shenzhou 13 give us a space lesson. What they said was vivid and lifelike, and we listened with relish.

They told us some space experiments, and we also know that space is buoyant. If you squeeze a drop of water, it will float around in the air. Besides, if you turn the cup upside down, not a drop of water will flow down.

They did an experiment. They put a ping-pong ball into the water. Then it's time to surprise us. They are holding a tube with a ping-pong ball in front of it. First, they press it, and then they quickly take it away. "Wow!" The students were all surprised. It turned out that table tennis actually sank into the water, and he was still tightly attached to the cup. If it is on the ground, then table tennis should float and not sink! The students were surprised from ear to ear. This experiment is really amazing!

Although this is a simple lesson, I feel the magic of the universe from it. I must be an astronaut in the future and drive a rocket to distant space! But I know I must study hard now and serve my country when I grow up!

Review of Tiangong Classroom 15 I watched the first lesson of Tiangong Classroom today and learned a lot of knowledge. The teacher of this lecture is not an ordinary "teacher" They are actually teaching in space! They are Mr Zhai Zhigang, Mr Wang Yaping and Mr Ye Guangfu. They are astronauts of Shenzhou XIII.

In this class, Mr. Yaping introduced us a lot of space science knowledge, including "demonstration of astronauts' working and living scenes in orbit", "experimental demonstration of space cytology research", "buoyancy disappearance experiment", "water film tension experiment", "water polo optical experiment" and "effervescent tablet experiment".

Among them, I am most interested in "water film tension experiment". Teacher Yaping showed us the experiment. I see a metal ring on the table. Teacher Yaping carefully took a drinking bag and injected water into the metal ring, so that the water could be adsorbed on the metal ring, and then continued to inject water slowly, and the water film became a bulging water ball. At the end of the experiment, Teacher Yaping put a flower cut by her daughter on the water polo. I was surprised to find that the flower kept spinning in the water polo. How interesting!

Teacher Yaping also took us to visit the interior of Shenzhou XIII. "Space Kitchen", which has a simple microwave oven and water dispenser, and a lovely small refrigerator with fresh fruits.

Teacher Ye also performed a space turn for us. I know that blowing and swimming are not feasible. You can only turn around with your arms around your chest. It's amazing!

My dream is that I want to be an astronaut, travel in the universe and explore more mysteries of the universe in space!
