Reflections after watching Tiangong Classroom

Tiangong Classroom aims to disseminate and popularize space science knowledge and inspire the enthusiasm of young people to continuously pursue the "scientific dream" and realize the "aerospace dream". Do you know what your impressions of Tiangong Classroom are? The following is my carefully compiled impressions of Tiangong Classroom. Welcome to read and collect. Reflections after watching Tiangong Classroom 1

When the astronauts taught us in space in "Tiangong Classroom", have you ever understood the efforts they put in for their dreams? They are celebrities, and they are just a Ordinary people who keep fighting for their dreams insist on making their lives special. Although dreams are beautiful, if there is no courage and action to persevere, then that beauty can only stay in a dream and will not become today's reality.

This reminds me of the days when I studied in the Children's Palace. I like to invent very much. Although my father supports it, my mother believes that "inventions cannot be eaten for a living" and does not approve of my learning to invent. I still remember my father saying: "Don't worry, son, you can study if you want to. This is your dream. Even if 10,000 people oppose it, just stick to it." What my father said really coincides with what Teacher Wang said. It made me more determined to learn painting. I think everyone has their own dream. I dream of becoming a painter, but sister Fu Lijuan has a pair of wings to fly. I admire her courage to jump in the blue sky - because I am afraid of heights.

Their deeds all tell us one truth - if you have a dream, you have motivation, and if you have motivation, you can succeed in your dream; if you have a dream, you must persevere, and only perseverance can lead to success; if you have a dream, you can excel, and only if you excel can you be considered successful. success.

Dreams will not abandon us, only we can abandon ourselves. No one can succeed casually, so although there will be various hardships and multiple tests on the journey to realize our dreams, which may even make us cry in discomfort and bring us a lot of pain, but if we give up, then There is nothing left. Therefore, no matter how painful, painful and tiring it is, we must persevere. Because persistence is the best way to achieve your dreams.

I also have my own dream - to be an inventor. Although this dream seems ridiculous, because more and more people are playing with inventions and thinking that inventors are nothing more than that. Some people may think that inventors are just redundant, unable to keep up with the times, and unable to create social value, but I don’t think so.

I like to appreciate those useful inventions with appreciative eyes and a happy mood, to understand what happened in past history, to listen to the voices of the ancients, and to trace the traces of their journeys. Although there are many difficulties to overcome, I will persist as always, just like them.

A dream is a key. It cannot open all the locks, but it can open our own locks. But there is a problem. This key may need to be polished by ourselves to make it more suitable for opening the lock of our dreams. A life that has not been carved is incomplete, so, my friend, let dreams shape our lives and let dreams lead us to success!

If you want to give up, please hold on to your hands. Key, strengthen my belief - I must open that lock! Reflections on watching Tiangong Classroom 2

The China Manned Space Engineering Office released news that in order to give full play to the comprehensive benefits of the China Space Station, China The first space science education brand "Tiangong Classroom" will be officially launched soon, and the first space teaching event on the China Space Station will be broadcast live to the world in the near future.

I was extremely excited to see this news, because we can once again see a series of wonderful phenomena of object movement in the microgravity environment of space. This reminds me of the space lecture in 2013.

In only 40 minutes, the astronauts only used five simple experiments to let everyone better understand the changes of objects and the principles of their changes in a weightless environment.

There were water film experiments and gyro experiments respectively... which made me realize that many incredible things can be done in a weightless environment. Among them, the one I am most interested in is the water polo experiment! First, use a ring similar to the size of a magnifying glass and put it into the drinking tap water bag. When you take it out, it turns into a water film. Then keep pouring water drops into it, and slowly the water film turns into a crystal clear water bag. water polo. If you insert a needle into a water balloon on the ground, it goes without saying that the water balloon will explode. However, in space, we can use a needle to inject ink into a water balloon, and the water balloon remains "unscathed". This is simply a miracle for us! This left the audience stunned.

The first man to go to the moon - Armstrong once said this: One small step for man, one giant leap for mankind. Although we can only watch space lectures on TV screens thousands of miles away now, I believe that one day we can go to space in person, communicate face to face with teachers, and experience the fun of being in space.

In the afternoon of December 9th, under the organization of the teacher, students in our school sat in the classroom and watched the first lesson of "Tiangong Classroom" through multimedia. The first lesson of "Tiangong Classroom" was in Chinese space. To elaborate, Tiangong Classroom allows us to experience the joy of exploration, perceive the mysteries of the universe, and interact between heaven and earth.

"Tiangong Classroom" started, space is really wonderful, it told about the food, clothing, housing and transportation of Chinese astronauts on the space station, and introduced us in detail to the internal design and function of the space suit. The function of the penguin suit is to reduce muscle atrophy. , cardiovascular function declines. Then he talked about the research on cell growth and development in the luminous suit of cell biology under weightless conditions, and explained in detail the myocardial cells. Cells are very magical in space. They beat under the fluorescence microscope, and the flashes are very shocking. The pieces of myocardial cells make contraction movement.

When it came to the question-asking session, the questions they raised were also unique. The first student asked Teacher Ye Guangfu and Teacher Wang Yaping in the space station, "In the space station, you can walk as freely as on the ground. "Teacher Wang Yaping gave us the answer. Because there is no help from gravity in the space station, people in the space station cannot walk like people on the ground. They always float around, and during the rotation process, the upper body turns to the right, the lower body turns to the left, the upper body turns to the left, and the lower body turns to the right. Actions such as blowing air cannot make them turn around on the space station. This is what Teacher Ye Guangfu showed us, but when the arm is rotated greatly, it can be turned around. The second student asked Teacher Wang Yaping, "Can the domestic water in the space station be recycled?" Teacher Wang Yaping answered us that because they used treated raw water, it cannot be recycled. And water has buoyancy on the ground. If you put a ping-pong ball in a water cup and press it down, the ping-pong ball will continue to surface. However, on the space station, the ping-pong ball does not surface. Instead, it sinks to the bottom of the water after being pressed. Teacher Wang Yaping explained to us that that is because the buoyancy force almost disappears in the space station.

The water film experiment was completed by Teacher Wang Yaping and Teacher Ye Guangfu *** together. This experiment made the flowers made by Teacher Wang Yaping and his daughter *** bloom in space. Then, Teacher Wang Yaping poured water into the water film to form a large water polo. Viewed through the water polo, Teacher Wang Yaping is an inverted image, which is formed by the image of a convex lens. Later, Teacher Ye Guangfu removed the small bubbles in the water polo and injected a large bubble into the water polo. Looking through the water polo, Teacher Wang Yaping could see two images, one positive and one negative. Teacher Wang Yaping took this opportunity to ask us, "Why are there two images, one positive and one negative? That's because the water polo is divided into two parts by the bubbles." Teachers Wang Yaping and Ye Guangfu also conducted an effervescent tablet experiment, and the picture was very spectacular. Later, several students from Nanning, Guangxi, Wenchuan, Sichuan, and Beijing asked Teacher Ye Guangfu and Teacher Wang Yaping unique questions. Teacher Ye Guangfu and Teacher Wang Yaping also answered their questions one by one.

Finally, three students expressed their feelings. The first student felt that the lens imaging was very shocking; the second student suggested that when the space station wants to turn around, it would be appropriate to fan it with a fan. You can turn around; the third student said that astronaut teachers have to overcome many difficulties on the space station and how difficult it is for them with heavy responsibilities, and he hopes that he will be as great as astronaut teachers in the future.

In this regard, the first space teaching session of the China Space Station was successfully completed.

My ideal is blue, but with a bright red added to it, which is the color of the national flag. I wore blue on my body and embroidered red on my chest. Reflections after watching Tiangong Classroom Part 3

This time, the "Tiangong Classroom" teaching targets mainly young people. It adopts an interactive method of collaboration between heaven and earth. Wang Yaping, astronaut of Shenzhou 13, serves as the main teacher. Ye Guangfu and Zhai Zhigang served as assistants and gave live lectures to everyone.

Three "space teachers" demonstrated three interesting science experiments for teenagers: table tennis experiment, water film experiment and effervescent tablet experiment. The students also conducted the above experiments on the ground. Since the weightless environment of space is completely different from the gravity environment of the earth, completely different experimental phenomena were presented, which aroused people's deep thoughts.

For example, if students immerse a table tennis ball in water, the ball will float on the water due to the influence of buoyancy. But in space, after immersing a table tennis ball in water, the ball hangs in the water and will not fall even if it spins back and forth in the air. According to Wang Yaping's explanation, this is because the buoyancy force will disappear inside the space station, so the ball will not be affected by the buoyancy force to float up.

Let’s talk about 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 ball that resembled a convex lens, and then added origami flowers. The flowers bloomed in the water ball, which is breathtaking. This is because the surface tension of water shows its power in a weightless environment, so the water will not flow downward, thus forming a water ball. Then inject bubbles into the water polo, and the bubbles will divide the water polo into two parts, forming two images, one positive and one negative. However, Wang Yaping did not tell us directly, but made us think and let us actively explore and discover scientific facts. Mystery.

I was greatly shocked by this lecture on the space station, which greatly increased my interest in science and planted the seeds of exploring the universe in my heart.

The blooming flowers in the water are like the prosperity of the motherland, blooming with their own brilliance, warm and beautiful. During 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 flying in space and every drop of seawater in the ocean carry the dreams of countless teenagers in China.

This is the second time that "Sky Classroom" has been held on the Chinese Space Station. We firmly believe that in the future, the Chinese 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 greatness. The scientific spirit, let us continue to look forward to the next course with a heart that loves science and explores the future!

Today, the teacher organized us to watch the Tiangong Classroom. I went to see the Tiangong Classroom with great anticipation. It was my first time to experience space life up close, and I was very excited.

First of all, when I saw them drinking water, they did not use our ordinary cups, but used a bag with a straw on it to drink water. I also noticed that instead of drinking from the beginning, they squeezed out the water first. Water can float in the air, and you can drink the water floating in the air into your stomach just by opening your mouth. I learned that things float because there is no gravity in space.

Then, they used the tension of water to make water balls from the water film. He explained to us the convex lens imaging experiment and let us understand the principle of the inverted image formed by the convex lens.

Through this Tiangong classroom study, I learned a lot of space knowledge.

Their courage to explore deserves our admiration! I must study hard and use my scientific and cultural knowledge to contribute to the aerospace industry of the motherland in the future! Reflections after watching Tiangong Classroom Chapter 4

Currently, we are facing major changes unseen in a century and embarking on a new journey of comprehensively building a modern socialist country. Opportunities and challenges coexist, and difficulties and hopes coexist. On the one hand, young cadres must take up the "baton" of the revolutionary cause, refine experience, enlighten wisdom, and forge ahead in the party's history of struggle. They must learn to be old scalpers, develop a spirit of dedication that does not care about gains and losses, a conscientious sense of responsibility, and worry about assume the important task of creating a new era. On the other hand, we must have a "positive youth" fighting attitude and mental state, study hard, increase our skills, take active actions, answer the "responsibility" of youth well, and run out of the "relay race" of national rejuvenation that belongs to youth. A generation of good results. The majority of scientific researchers should further carry forward the spirit of aerospace, climb to the peak of science and technology, and embark on the long march of the new era.

Carry forward the patriotic spirit of "I grew up here to serve the country." In the early days of the development of my country's aerospace industry, many successful and talented scientists gave up the favorable conditions abroad and returned to their motherland without hesitation. Many R&D workers are willing to be unknown heroes, hiding their names and making silent contributions. Some even sacrificed their precious lives. They used their blood and lives to compose a moving poem in which they devoted themselves to the motherland and the people and died. Scientific research talents in the new era must learn from the older generation of scientists, firmly believe in scientific and technological innovation and serving the country, integrate the pursuit of their careers into the needs of the country, inherit the tradition of patriotism and dedication of their predecessors, and take the needs of the country and nation as the research orientation. On the road to serving the country scientifically and strengthening the country through science and technology, we will achieve the perfect integration of individuals, careers, and the country.

Carry forward the spirit of struggle of “resulting in perseverance despite repeated hardships”. In the vast Gobi desert, in the sparsely populated mountains and canyons, sleeping in the open air and working tirelessly, the older generation of scientific researchers have overcome all kinds of unimaginable difficulties and obstacles. They used limited scientific research and experimental means, relied on science, worked hard, worked hard, and innovated to overcome technical difficulties one after another, and achieved great victory in the cause of "two bombs and one satellite". In this era, we are undoubtedly lucky. Both the living environment and scientific research conditions are far better than those of the older generation of scientists. Contemporary scientific researchers follow the example of the older generation of scientists, vigorously promote the spirit of self-reliance and hard work, work hard in their respective fields, and create new achievements.

Carry forward the spirit of unity that “everyone adds fuel to the flames.” In the extraordinary process of developing "two bombs and one satellite", thousands of scientific and technical personnel, engineering technicians, and logistics support personnel from all regions and departments across the country worked together and worked together to form a team that marched towards the peak of modern science and technology. A mighty team. With their brilliant achievements, they have added a dazzling page to the history of civilization creation of the Chinese nation. Scientific research is a complex and arduous group labor. The interaction between people in scientific research activities directly affects scientific research collaboration and the completion of scientific research plans. The majority of scientific research workers must firmly establish a sense of the overall situation, a sense of collaboration, and a sense of service, keep an eye on common goals, and coordinate with each other while giving full play to their respective strengths.

At 0:23 on October 16, Beijing time, the Long March 2F Yao-13 carrier rocket carrying the Shenzhou 13 manned spacecraft was ignited and launched from the Jiuquan Satellite Launch Center. The manned spacecraft successfully separated from the rocket and entered the predetermined orbit, successfully sending the three astronauts Zhai Zhigang, Wang Yaping, and Ye Guangfu into space. The three astronauts rushed to the sky with the expectations and blessings of all Chinese people, heading for China's space home in the vast universe.

Although the launch time was in the early morning, as soon as the news of the "complete success" came out, the Internet was filled with joy. Countless netizens were waiting for this moment, and their hearts were surging for the success of the launch.

According to China’s aerospace industry’s never-ending “practice”, Shenzhou 13 will also achieve multiple “firsts”: achieving radial rendezvous and docking with the core module; staying in orbit for 6 months for the first time. It is also the normal residence period of the astronaut crew during the operation of the space station; it is the first time that the rescue ship has been transferred to the official mission ship.

In addition, compared with Shenzhou 12, Shenzhou 13 also has many special features. For example, after docking at the Chinese Space Station, the space station will have a core module, 2 cargo spacecraft, and 1 manned spacecraft. ***Four aircraft are combined to operate; and the spacecraft and rockets carrying out the mission are also directly converted from emergency standby backup status to launch status at the launch site.

Moreover, after the Shenzhou 13 mission, all on-orbit verification of all functions of the standard manned spacecraft for the space station mission will be completed, fully capable of supporting the subsequent construction and operation needs of our country’s space station, and also marking the key milestone of the project. The technical verification stage has officially transferred to the on-orbit construction stage, which is of extremely important significance.

As netizens said, "You can always trust China Aerospace." China Aerospace is always surpassing, achieving technological breakthroughs bit by bit, and refreshing the scale in outer space at an increasingly faster frequency. After several generations of hard work and dedication, we can proudly say today that China has become an important "player" in the world's space exploration, and there will be more and more human footprints from China in space.

Putting aside the shock brought to us by the technical aspects, the overall temperament of China's aerospace industry today is becoming more and more calm, confident, warm and romantic, and has increasingly unique Chinese charm.

For example, the flight crew of Shenzhou 13 included China’s first female space station astronaut—Wang Yaping. Before departure, she posted on WeChat Moments “Business trip for half a year”, with a light and gentle sense of humor. The expression exudes confidence. At the expedition site, Wang Yaping's daughter came to see her mother off and shouted "Come on, Mom". This scene moved countless people, and "Mom is going to pick the stars for you" quickly became a hot topic on the Internet.

The mission of Shenzhou 13 will last for half a year, and will span the Chinese Lunar New Year. The first time astronauts celebrate the Spring Festival in space also attracts much attention. Earlier, when the Tianzhou-3 cargo spacecraft delivered "space express" to the space station, it had already prepared Spring Festival supplies for the astronauts. The astronauts will also stay awake with all Chinese people and send New Year blessings from space to the Chinese people as soon as possible. These meticulous and ingenious arrangements give the hard-core "technological narrative" of aerospace a strong sense of humanity.

Now, Shenzhou 13 has officially started its space journey. We wish the astronauts a successful completion of the mission, and believe that China’s aerospace industry will bring us a steady stream of surprises, and will bring our great country’s aerospace industry to the forefront. The dream takes you further. Reflections after watching Tiangong Classroom Part 5

Today, we participated in the first space lecture of the Chinese Space Station’s “Tiangong Classroom” in the classroom. The astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu of the “Shenzhou 13” gave us I had a lively and interesting physics class.

First of all, Teacher Wang Yaping showed us the main structure of the Tianhe core module, and took us to visit the living area, health area and space kitchen. Later, the teacher also introduced the use of space treadmills, space bicycles, "penguin suits" and other exercise devices, and explained the importance of exercise in space: the space station has almost no gravity, and the microgravity environment will cause blood to surge and weaken bones. Looseness and muscle atrophy require consistent exercise to stay healthy. Teacher Ye Guangfu also demonstrated for us how to walk and turn around in space, which gave us a better understanding of the life of astronauts in space.

Then comes the most exciting part of the space experiment. The three teachers demonstrated space cytology experiments, buoyancy experiments, effervescent tablet experiments, etc. Among them, the most impressive one was the water balloon imaging experiment. Teacher Wang Yaping first made a water film, and then slowly poured water into the water film. Due to the strong surface tension in a microgravity environment, the water film turns into a crystal clear water ball. The teacher injected another bubble into the water, and when he put his face close to the water balloon, two images, one positive and one negative, appeared in the water balloon.

The teacher explained that this is because the bubbles split the water ball into two parts, making them imaged separately. After such a unique "Tiangong Class" ended, I finally understood the statement that "space teaching is the most vivid practical case in the physics classroom."

Just as Teacher Wang Yaping gave us young people a message at the end of the course, "We are the flowers of the motherland waiting to bloom, and we hope that our dreams will bloom in the vast expanse of space." Our task today is to work hard to learn science Cultural knowledge, serve the motherland in the future, and contribute my own modest efforts to the motherland's aerospace industry and scientific and technological development!

"Tiangong Classroom" finally meets us. Today the school organized us to watch this exciting program. This time the class was moved to the Chinese own space station, hosted by three people in the Tianhe core module. An astronaut brought us a special "space lecture".

At 0:23 on October 16, 2021, the Long March 2-13 carrier rocket carrying the Shenzhou-13 manned spacecraft was accurately ignited and launched at the Jiuquan Satellite Launch Center according to the scheduled time, about 582 seconds Later, the Shenzhou 13 manned spacecraft successfully separated from the rocket and entered the predetermined orbit, successfully sending the three astronauts Zhai Zhigang, Wang Yaping, and Ye Guangfu into space. The astronauts were in good condition and the launch was a complete success.

“The dream of flying never loses weight, and the dream of science has infinite tension.” Eight years ago, “space teacher” Wang Yaping’s space lectures left a deep impression on everyone, and now she has set foot in space again During the journey, she will become China's first female astronaut stationed on the space station, and China's first female astronaut to leave the spacecraft. Wang Yaping is in space, facing the earth and teaching people on earth. He is the first space teacher in China, demonstrating the demeanor and magnificence of a major space country.

This space teaching activity was conducted in an interactive way between space and earth. A main classroom on the ground was set up at the China Science and Technology Museum, and sub-classrooms on the ground were set up in Nanning, Guangxi, Wenchuan, Sichuan, Hong Kong, and Macao. Three astronauts introduced and displayed the working and living environment of the Chinese space station on the space station, demonstrating cytology experiments in a microgravity environment. Cells were beating continuously under a fluorescence microscope; microgravity environments are difficult to obtain on the earth and cannot be completed on the ground. Moving to space makes the experimental phenomena more direct and intuitive. The liquid surface tension test makes water turn into a water film in space; after continuing to inject water, a water sphere is formed; after injecting bubbles into the water sphere, two images, one positive and one negative, are formed; deepen the understanding of basic physics such as mass, weight, and Newton's law Understanding of conceptual laws. There are also phenomena such as astronauts moving in a state of zero gravity, communicating with ground classes in real time, disseminating manned spaceflight knowledge, and stimulating our interest in science.

Wang Yaping said: "Facing the vast universe, we are also students. I am looking forward to being able to perceive and explore the magical and wonderful space with the majority of young friends, and gain knowledge and happiness." The universe is The universe is vast, magical, complex and changeable. There are many mysteries in the universe that are worth exploring.

The old ambition of "reaching the moon in the sky" is no longer a dream. Chinese astronauts want to turn the myth of the sky into reality. Indeed, more and more Chinese aerospace figures in the vast space are turning the Chinese nation's romantic feelings for the vast stars into a realistic poem of space exploration. It is reported that the astronauts of Shenzhou 13 will stay in space for 6 months, and Chinese astronauts will spend the Spring Festival in space for the first time. We look forward to being able to hear the astronauts’ blessings from space as soon as we stay awake on New Year’s Eve.

I believe that in the future, we will create more aerospace miracles and realize newer and larger "aerospace dreams". We will eventually write a wonderful stroke in the starry sky and make our way into the vast universe. Leave a more wonderful mark on China.
