On March 23rd, 2022, at 15:40, the second class of Tiangong Classroom officially started. "Space teachers" Zhai Zhigang, Wang Yaping and Ye Guangfu brought a wonderful space science lesson to the teenagers of China Space Station.

This time, China astronauts passed on scientific knowledge in 300 kilometers of space, showed the charm of the universe to the world with various space experiments, and inspired countless students' interest in mysterious space. Teacher, preach and teach. However, teaching scientific knowledge in person by giving lectures in space can only be a feat that can be accomplished in modern human history. When Confucius was studying in Xinglin, how could he think that one day, his descendants would rush to space like Chang 'e and preach and dispel doubts in space? It is said that "teacher is the most glorious profession under the sun", but Morgan and Wang Yaping spread the glory of this profession into space, and let the whole universe be bathed in the glory of human nature. If the vast universe is a book, then the powerful comprehensive national strength and solid space technology are undoubtedly the wisdom keys to open this book.

China astronauts' teaching in space has opened a magical space journey for us, and their Voice of China is also infecting and touching everyone around us. However, the unknown vastness and far-reaching educational significance of space also put forward higher requirements for China's manned space flight. If we want to absorb more nutrition from the universe, we must vigorously develop manned space flight and education. This space teaching has aroused students' inner love for learning, which can be transformed into simple feelings of loving the motherland, learning and science. Let us teach less in our daily work and encourage and train future successors more attentively.

Comments on the Teaching of Class Two in Tiangong

I watched the "space-class" teacher's lecture with the children and experienced the real zero-delay air class! This kind of learning materials that shocked the whole world and the unique interactive teaching between heaven and earth made us feel different from the science classroom on land. When the sound of nature came back to the big classroom on the ground from the experimental cabin of the space station, everyone held their breath and stared, and from time to time they gave out bursts of wonder. As a science teacher for children, I know that these frank eyes are full of curiosity, shock and pride. I think this is the strength of science and technology in China, the children's most natural interest in science, and our national confidence in science and technology in China. I believe that the seeds of today's space flight have been successfully sown, and the bright star of the future, China Space Youth, will relay the voyage!

Today's lecture on space in China Space Station opened my eyes, and I saw something that I couldn't do on earth. For example, if you put a ping-pong ball in the water, you can only float on the water. When the astronaut teacher put the ping-pong ball into the water and fell on time, the ping-pong ball was immersed in the water and could not float. To my great surprise, buoyancy disappeared in space. It is so magical that it shows the mysterious side of science and leaves a deep impression on me. Also, when Teacher Yaping told us that they could see the sunrise at 16 on the China Space Station, I suddenly felt a little envious. Seeing such a beautiful scenery is also a kind of spiritual enjoyment. When Teacher Yaping showed us one wonderful experiment after another, I thought of not only the fun brought by scientific exploration, but also the spiritual quality of astronauts who are not afraid of sacrifice, hard-working and brave in dedication, as well as the unremitting efforts and hard work of researchers. All these make me admire very much, and they are also worthy of our teenagers to study hard and contribute to the prosperity of the motherland.

The second lesson of "Tiangong Classroom" will be held at China Space Station on the afternoon of March 23rd. The astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu of Shenzhou XIII will cooperate in teaching. This space teaching activity will continue to be conducted in the form of dialogue between heaven and earth. Astronauts will demonstrate space "ice and snow" experiment, liquid bridge demonstration experiment, water-oil separation experiment and space parabolic experiment in orbit, and introduce and display space science facilities. The second lesson of "Tiangong Classroom" aims to spread the knowledge of space science and stimulate the enthusiasm of young people to pursue "scientific dreams" and realize "space dreams".

As we all know, after several generations of unremitting efforts, China's space industry has made brilliant achievements. China astronauts are not afraid of hardship, but dare to climb and fight. They strive for perfection in their work, and are a team that can bear hardships, fight and tackle key problems, thus forming the "aerospace spirit." If we want to inherit the aerospace spirit, we must rely on the vast number of young people to give good lessons. Therefore, the "Tiangong Classroom" is the place where young people's space dreams begin and a good platform to show their space spirit.

"Tiangong Classroom" gives teenagers a close and in-depth understanding of space knowledge and intuitively feels the great mysteries of science through vivid explanations by three astronauts. After reading the second lesson of Tiangong Classroom, I benefited a lot. I not only realized the importance of the space industry, but also became more enthusiastic about learning science. "Tiangong Classroom" has set up lofty ideals since childhood, planted scientific seeds in my heart, and inspired my endless desire to explore!

On March 23rd, my classmates and I watched the second lesson of China Aerospace Tiangong Classroom. The astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu of Shenzhou XIII once again became "space teachers" and gave us a very lively and interesting lesson.

202165438+On February 9th, the first lesson of "Tiangong Classroom" officially started. The astronauts Zhai Zhigang, Wang Yaping and Ye Guang Fu of Shenzhou XIII cooperated with each other to give lectures, which were splendid in China Space Station and broadcast live to the whole world. This is the first time that China astronauts have taught in space after eight years, and it is also the first time that China Space Station has taught in space. Their speeches were wonderful, successful and popular. After the first class, the second class of "Tiangong Classroom" is even more exciting.

This space teaching activity will continue to be conducted in the form of dialogue between heaven and earth. Astronauts will demonstrate space "ice and snow" experiment, liquid bridge demonstration experiment, water-oil separation experiment and space parabolic experiment in orbit, and introduce and display space science facilities. For example, the space "ice and snow" experiment demonstrated the crystallization of saturated liquid under weightlessness. The second lesson of "Tiangong Classroom" aims to spread the knowledge of space science and stimulate the enthusiasm of young people to pursue "scientific dreams" and realize "space dreams".

I still remember the space experiment in the first lesson of "Tiangong Classroom": "space fitness", "cell culture" and "buoyancy disappeared". Among them, what impressed me was a series of experiments on water made by Wang Yaping astronauts. Due to weightlessness, water presents a wonderful phenomenon completely different from the ground. In the second lesson of Tiangong Classroom, what impressed me the most was the water-oil separation experiment. As we all know, water and oil are separated in normal environment. However, the phenomenon of water-oil stratification disappears in weightlessness environment, and the experiment also demonstrates the phenomenon of stratification through the centrifugal force generated by rotation. It's incredible!

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 took us to watch the Shenzhou 13 course, and people from all regions were watching it, including Beijing, Jinan and Shandong. Shenzhou 13 created many firsts. The most impressive thing is the water film, because there is no gravity of the earth, which can float in the air and become a round water polo after being washed with water. The most interesting thing is that the astronauts dropped a few drops of paint in it and put an orange effervescent tablet from the water polo. After a while, it was like eating a lot of bubbles. It soon became bigger and bigger, bigger and bigger. It used to be as big as a ping-pong ball, but now it is as big as a palm.

Uncle Ye Guangfu showed us how to turn around in space. He first tried to turn around directly, but as soon as he turned around, he floated up. Then he took a deep breath. He chose to take a deep breath and turn around. As a result, he just jumped up and did not turn around. He showed us how to turn around in space. 1 is turned with tools. The second is to spread out your hands. Wait until you turn around and put your hands back. The third is turning with the right hand and turning around.

This experiment is amazing, salute to all astronauts. This is the dream of many people, hoping that the motherland will become stronger and stronger. We were born under the red flag and grew up in the spring breeze. The people have faith, the country has strength, and the nation has hope. Our eyes are all on China, and five-star shining is faith.
