Comment on "Tiangong Classroom"

After carefully tasting a work, we can absorb new ideas from it. It's time to take the time to write it. Don't think you can handle feedback casually. The following is the feedback from the Tiangong class I collected for you. Welcome to reading. I hope you will like it.

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. 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 Class" is like a key, which has solved many mysteries for us. In space, Wang Yaping and three other 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 space necessities such as "penguin suit" and mini refrigerator. Interesting experiments have aroused our curiosity and imagination about space, and we are eager to acquire more mysteries of the universe.

After reading this lesson, our expectations for space are even greater, and my "space dream" is also stronger. 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 exciting. Our three astronauts in China, Zhai Zhigang, Wang Yaping and Ye Guangfu, brought us an interesting "Tiangong class". We have seen some wonderful phenomena such as "space turn", "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!

Reflections on No.4 Classroom in Tiangong There is a touch of gorgeous China red in that blue space, which is the pride of China people.

Today, we watched Aunt Wang Yaping's Tiangong Classroom. 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 of lower limbs will upwell, 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 of space, buoyancy almost disappears, so table tennis can't float. Space is amazing. I want to see more.

Reflections on Tiangong Classroom 5 We just watched the lecture video of Tiangong Classroom, and three teachers, including Wang Yaping, gave us wonderful lectures. We watched dynamic biological cells and beautiful water films. At the moment when blue is injected into the water film, the water polo becomes bigger and bigger. We seem to see a blue earth. We feel how lucky we are to live on the earth. At the same time, I think I should study hard and work hard to realize my dream!

At the same time, we also thank the school for providing us with the opportunity to learn this time. When we grow up, we must arm ourselves with what we 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 his body, and then opened his hands, so the speed slowed down. If he puts his hand on his shoulder, the speed will become 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 and our motherland are really great!

Thinking about Tiangong Classroom 7 We sometimes forget that besides the cities, villages, mountains and the earth where we live, there is also a 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 around. 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 the things on the earth that go against the common sense of the state of nature. The water polo made of spinning gyro and mirror let me know that I can do many things without gravity! In fact, the first lesson in the Heavenly Palace gave me two biggest feelings: shock and longing for knowledge of the universe, which really refreshed my understanding of the universe. I am really lucky to see the first lesson in Tiangong.

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 popular science class. The details of astronauts' life in space are open to the public, and the spacewalk, special spacesuit, cell observation in weightlessness ... one after another have opened my eyes. What impressed me the most was the various manifestations of water in weightlessness in space: without the constraint of gravity, water would become a small drop in space. Even more amazing is that if there is no gravity, buoyancy will disappear! Just like magic, the water in the hands of the astronaut's uncle becomes a water film, a thick water film or even a crystal ball. It's amazing!

After watching this live class, I felt the magic of space flight 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!

I watched it today, and 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. Put a cup on the ground, fill it with water and put it in a table tennis ball, and the table tennis ball will float on the water. In the universe, fill a cup 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 groundwater, 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, it will emit a lot of bubbles. 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.

Chinese astronauts have always been a very romantic group, and they are committed to turning the mythical sky into reality. The Goddess Chang'e flying to the moon, Yutu waits, Kuafu watches day and night, Beidou shows the way, and Zhu Rong follows. ...

Today, the aerospace course starts again after eight years. I was deeply shocked to see the whole course. Chinese sons and daughters 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 the 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 also answered the long-hidden unsolved mysteries of the students. This aroused the students' interest and felt that the questions in their hearts finally had the exact answer. Astronauts also demonstrated many interesting small experiments in microgravity, such as cytology experiment, object movement and liquid surface tension. 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 that they will be astronauts when they grow up.

Comments on Tiangong Classroom 12 Today, we watched the "Tiangong Classroom", which is the exclusive live broadcast in the world, and 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 popular 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 gave us a live lecture about Tiangong on the big screen, all about space.

It's interesting in a spaceship. The 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 of the Shenzhou XIII astronaut on the China Space Station. Teacher Wang Yaping showed us some wonderful phenomena in space, such as buoyancy disappearance experiment, water film tension experiment and effervescent tablet experiment in microgravity environment. When I saw the effervescent tablets injected with water polo, the bubbles produced were beautiful, and I couldn't help but sigh the magic of the universe!

After watching this lecture on space, I learned a lot, not only about the life of astronauts in space, but also about many principles. Science is everywhere, and interesting experiments have filled me with infinite yearning for space.

Comments on Tiangong Classroom 15 Tiangong Classroom. I benefited a lot and learned the mystery of space: in space, the human body is difficult to rotate, astronauts can't walk normally without gravity, and 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, which makes me amazed. I am very much looking forward to the next Tiangong class, and I don't know what it will bring us.
