Comments on tiangong classroom

After watching a film and television work carefully, what did you learn from this movie? The most important feeling at this time is that you can't forget. How to write a good book review? The following are my collected essays (8 selected essays) about feedback from Tiangong class, for reference only. Let's have a look.

On the afternoon of February 9th, 200212002, I watched the space lectures given by astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu of China Space Station with excitement.

On TV, space teaching has begun, and astronauts have brought us into a brand-new space environment through interesting experiments. Gentle tone, humorous language, let me open my eyes in front of the screen and concentrate. I was also very moved after watching this space lecture.

Teacher Wang Yaping showed us around their space home. Through some experiments, we witnessed the wonderful difference between the weightless environment of the earth and space. All kinds of experiments are the result of careful preparation and close cooperation between astronauts and ground staff, and are guaranteed by advanced space technology.

Looking up at space, we are concerned, because there are our dedicated China astronauts in the space station; We are confident, because the purpose of China astronauts is to turn the myth of heaven into reality, and the "China Star" shines all over the world! In the vast space, there are more and more China astronauts, expressing the romantic feelings of the Chinese nation for the vast starry sky, from "two bombs and one satellite" and "the Goddess Chang'e flying to the moon" to "Beidou" to guide the way, "Tiangong" to range rover and "Tian Wen" to explore the fire, and then to "Shenzhou" series to roam the sky and "xi River" to chase the sun. As far as the eyes of China people are concerned, what they look up to.

After this class, I will be proud of China's space technology, and I am proud of our motherland! As a primary school student, I should study hard now, master more scientific knowledge and explore the mysteries of space in the future.

Reflections on the Tiangong Classroom 2 This "Tiangong Classroom" is mainly aimed at teenagers and adopts the mode of interaction between heaven and earth. Wang Yaping, the astronaut of Shenzhou XIII, is the main teacher, and Ye Guangfu and Zhai Zhigang are teaching assistants, giving lectures on the spot.

Three "space teachers" showed three interesting scientific experiments for teenagers: table tennis experiment, water film experiment and effervescent tablet experiment. The students also carried out the above experiments on the ground. Because the weightlessness environment in space is completely different from the gravity environment on earth, they present completely different experimental phenomena, which arouse people's deep thinking.

For example, if students immerse table tennis in water, the ball will float on the water because of buoyancy. But in space, after the table tennis is immersed in the water, the ball is suspended in the water and will not fall even if it rotates back and forth in the air. According to Wang Yaping, this is because the buoyancy will disappear in the space station, so the ball will not be affected by buoyancy.

Let me start with the experiment that impressed me the most-the interesting water film experiment. Wang Yaping poured water into the metal ring to form a large water polo like a convex lens. When the origami flowers were put in, the flowers in the water polo opened, which was amazing. This is because the surface tension of water in weightless environment shows great strength, so water will not flow downwards, thus forming water polo. Inject bubbles into the water polo, which will divide the water polo into two parts, forming a positive image and a negative image. But Wang Yaping didn't tell us directly, but caused us to think, let us actively explore and discover the mysteries of science.

This lecture in the space station has greatly shocked me, greatly increased my interest in science and planted the seeds of exploring the universe in my heart.

Flowers in full bloom in the water, like the prosperity of the motherland, are blooming with their own brilliance, warmth and beauty. In the live broadcast, we not only learned a lot of knowledge, but also saw the beautiful scenes of the earth's surface and space. Every star roaming in space and every drop of seawater in the sea carries the dreams of countless teenagers in China.

This is the second time that "Sky Class" has been held in China Space Station. We firmly believe that in the future, China Space Station will continue to use the unique and rich resources in space to guide and encourage young people to actively explore and carry forward the great scientific spirit. Let's continue to look forward to the next course with a heart that loves science and explores the future!

Reflections on Tiangong Classroom 3 I watched the first lesson of Tiangong Classroom today and learned a lot. 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!

Reflections on Tiangong Classroom 4 Today, we attended the first space lecture in Tiangong Classroom of China Space Station. The astronauts Zhai Zhigang, Wang Yaping and Ye Guang Fu of Shenzhou XIII gave us a lively and interesting physics lesson.

First of all, Mr. Wang Yaping showed us the main structure of Tianhe core cabin, and successively showed us the residential area, sanitary area and space kitchen. Later, the teacher also introduced the use of space treadmills, space bicycles, "penguin suits" and other sports equipment, and explained the importance of exercising in space: the space station has almost no gravity, and the microgravity environment will make people's blood swell, bones loose and muscles atrophy, so it is necessary to keep exercising to stay healthy. Teacher Ye Guangfu also showed us how to walk and turn around in space, which made us better understand the life of astronauts in space.

Then, the most exciting space experiment. Three teachers demonstrated the space cytology experiment, buoyancy experiment and effervescent tablet experiment, among which the water polo imaging experiment impressed me the most. Teacher Wang Yaping made a water film first, and then slowly filled it with water. Due to the strong surface tension in microgravity environment, the water film has become a crystal clear water ball. When the teacher injected another bubble into the water and put his face close to the water polo, two images appeared in the water polo, one positive and the other negative. The teacher explained that this is because the bubble divides the water polo into two parts, so that it can be imaged separately. After such a unique "Tiangong Classroom" ended, I finally understood the sentence "Space teaching is the most vivid practical case in physics classroom".

Just as Teacher Wang Yaping sent a message to our teenagers at the end of the course, "We are flowers in bud in the motherland, and we hope our dreams will bloom in the vast space", our task now is to study hard scientific and cultural knowledge, serve the motherland in the future, and make our modest contribution to the aerospace industry and scientific and technological development of the motherland!

Reflections on Tiangong No.5 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!

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!

78 years ago, astronaut Wang Yaping gave his first space lecture with the help of Nie Haisheng and Zhang, and planted the seeds of space and science in the hearts of countless children. Now, she has once again embarked on a trip to space, bringing us the unforgettable first lesson of "Tiangong Classroom" today.

In the "Tiangong Classroom", teachers Wang Yaping, Zhai Zhigang and Ye Guangfu showed us the experiments of space turning, buoyancy disappearance, water film tension, water polo optics and effervescent tablets in the space station, which made people feel endless fun and mystery. Among so many interesting experiments, my favorite is the optical experiment of water polo. When Miss Wang Yaping stands in front of the water polo, we can see that her appearance is the other way around, because the water polo is equivalent to a convex lens, and Miss Wang Yaping presents a handstand through the water polo. Then, when Miss Wang Yaping injected a big bubble into the water polo, she stood in front of the water polo again. At this time, we can see that she shows a positive and a negative look. This phenomenon is really amazing. The students who watched in class kept exclaiming and expressing their yearning for science with warm applause. There are many amazing experiments, so I won't explain them one by one. Every experiment is wonderful and makes people feel incredible.

I have benefited a lot from this study. A strong teenager makes a strong country. I will also study hard and strive for the opportunity to travel in space when I grow up. "Tiangong Classroom" shows our confidence to the world and wishes the motherland more prosperity and strength!

At 3: 40 this afternoon, Cui Zhigang, Wang Yaping and Ye Guang Fu of Shenzhou XIII gave us a lesson about living in outer space. After listening to it, I found it very interesting and gained a lot.

At first, what you see is a floating top. Then, three teachers appeared in succession. The first appearance was Wang Yaping, who introduced us to some things in the space capsule, such as the space runway, space cabinets, water dispensers and so on. I think space is really wonderful. The space kitchen in the capsule is fully functional, and they can eat fresh apples. Teacher Wang Yaping also told us that if we look fat in space, it's because of the surge of blood caused by microgravity, which also let us know that if we don't exercise in space for a long time, it will affect our health.

Under the leadership of Mr. Wang, we met Mr. Ye Guangfu and Mr. Ye step by step. They introduced Mr. Ye's clothes-penguin suit. It has some braces in many places, and it can also fight against muscle atrophy and cardiovascular function decline. Amazing, isn't it? Behind the little clothes are the whimsy of scientists. After that, Teacher Ye introduced us to the space cytology experiment. It is equivalent to their research on cell growth and development under weightlessness. Of course, the microscope is taken out from the "medical sample microscopic observation and recording device". Put the sample under the lens of a microscope, and then use software to observe and detect the cells. Cells in space are different from those on earth. The cells in space are very active, which is really an eye-opener. It seems that this lesson will also help our biology. In the table tennis experiment, the teacher taught us that buoyancy appears with gravity and almost disappears in the space station. You have gained a lot here.

What impressed me most in this course was a series of experiments on water polo. When a bubble is injected into the water polo, two images will be formed in the water polo, one is positive and the other is negative. If it is on the earth, water polo is impossible to exist, and it will directly turn into liquid and disappear, not to mention this phenomenon. Another experiment is to put an effervescent tablet in a water polo. As we all know, effervescent tablets form a series of small bubbles when they meet water. Three teachers dyed the water polo blue first, and then put the effervescent tablets there. At that time, I felt that this water polo was very similar to the earth, so I felt intimate.

This "Tiangong Classroom" made me feel that China's development technology is really first-class. China was trampled and bullied in the past, but now China has finally stood up! Won't be bullied again! Moreover, I admire these three "teachers" They can't even go home for the holidays, but continue to study outer space for the world. I am deeply moved by this spirit of self-sacrifice. I really hope that the "Tiangong Classroom" can have a second class and a third class, so that we can learn more knowledge!
