Reflections on the second lesson of "Tiangong Classroom"

After watching a film and television work, I believe you will have many feelings. Why not write a review record? Then can you write it down? The following is my review of the second lesson of Tiangong Classroom. I hope it will help you.

Three astronauts took us to do many experiments: space ice and snow experiment, liquid bridge demonstration experiment, oil-water separation experiment ... and also took us to visit their experimental platform. Of course, what impressed me most was the experiment of water-oil separation. Astronauts are really great, rejuvenating the country through science and technology, and the road to self-confidence is successful. I praise China Aerospace and pay tribute to the hard work and selfless dedication of China astronauts!

Lesson 2 Review of Tiangong Classroom 2 Today, we watched the second issue of Tiangong Classroom. Three astronauts went into space to give us lessons. The difference is that there can be a dialogue between heaven and earth in the Tiangong classroom, which is really interesting!

I think, the science and technology of our motherland also found the answer in failure, so I know that there will be no bumps on the road of learning, and you can succeed only if you strive to cross it. The wisdom of young people leads to the wisdom of the country. We should study hard, pursue our dreams bravely, and try to solve the unsolved mystery that has been with us for a long time.

Today, I watched the second lesson in the Tiangong class, and I was very excited to feel the space life at close range again with great expectation. Among them, I think the most magical plot is that Teacher Wang Yaping made a very beautiful "ice hockey". I saw the water polo slowly turn into a "ice hockey", but the teacher said it felt very hot. I want to touch it, too But Wang Yaping said that "ice hockey" can't be done on land, and it can only be done in microgravity. Space experiments are really amazing and interesting. I really want to be as brave as them when I grow up to complete the sacred space mission of the motherland!

Comments on the second lesson of "Tiangong Classroom" 4 Today, our whole class watched the live space class together, and several astronauts' uncles and aunts gave us a very vivid science lesson. The details of astronauts' life in space are made public, including spacewalk, special spacesuit and cell observation in weightlessness. ...

All the piles opened my eyes. What impressed me the most was the various performances of water in the weightless environment in space: without the constraint of gravity, water would become a small drop in space. What's even more amazing is that without gravity, buoyancy will disappear! Like magic, the water in the hands of the astronaut's uncle turned into a water film, a thick water film, and even a crystal ball. It's amazing! After watching this live class, I felt the magic of space 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!

Comments on Lesson 2 of Tiangong Classroom 5 Through the detailed speeches of teachers Wang Yaping, Ye Guangfu and Zhai Zhigang, I watched interesting experiments of "ice and snow" in space, parabolic experiments in space and demonstration experiments of liquid bridge. Under the introduction of three astronaut teachers and hosts, I learned about space science facilities. Finally, the interaction between heaven and earth also opened my eyes. I also learned about the busy life of astronauts in space, which made me realize the hardships of being an astronaut. Although we can't travel in space like astronauts yet, as Mr. Zhai Zhigang said, "You should study hard now, and anything is possible!"

2000 years ago, Qu Yuan raised a question in Tian Wen: The sun and the moon are safe, and the stars are safe. It is precisely because we are the first to look up at the starry sky and ask how big the universe is, why the stars run regularly and what shape the earth is, that our human civilization can rise step by step.

After reading "Tiangong Classroom", I have more curiosity and questions about the magical universe. Space cytology research, space turn, buoyancy disappearance experiment, water polo optical experiment, etc. All of them have opened my eyes, not only broadened the boundaries of my thinking and cognition, but also gave me a new understanding of science.

Today, we started a new journey of asking for the sky. You and I, teenagers, are witnesses and participants in China's space exploration. Under the night sky, the stars are bright, waiting for us to explore.

Lesson 2 Review of Tiangong Classroom 7 Today is really lucky. I watched the mysterious "Tiangong Classroom" with my classmates. My uncles and aunts taught us a lot of scientific knowledge by giving lectures in space, and also took us to visit their space homes. The previously unreachable space can become within reach! The knowledge of space mysteries in the book has also been well proved under the operation of astronauts' uncles and aunts! If we hadn't seen it with our own eyes, we couldn't have imagined that technology was such a magical thing! Look, table tennis will float on the water on the ground, but in space, it will sink to the bottom with a touch!

The students cheered and shouted incredible! At this moment, I made up my mind that we should make greater efforts, study hard, learn more knowledge and explore more mysteries!

Lesson 2 Review of Tiangong Classroom 8 There are many interesting things in space life. Astronauts must live in space for six months. Maybe you think that living in space must be very happy and difficult. Let's take a look at how three astronauts-Zhai Zhigang, Wang Yaping and Ye Guangfu lived in space!

When it comes to life, I have doubts. What's the difference between sleeping on the earth and in space? Because there is no gravity in space, astronauts sleep in sleeping bags. Interesting!

Eating is no stranger to everyone. Water and rice lose their gravity in space and will float in the air. Astronauts can eat in the air. That's fun!

I like the universe and space. I wish the astronauts an early return, peace and health. We are all looking forward to your return! After this lesson, I understand that we should set up lofty ideals from childhood, serve the motherland in the future and work hard for our dreams!

Comments on Lesson 2 of Tiangong Classroom 9 Human exploration of space has never stopped, from Zhang Heng to Zu Chongzhi to the Wright brothers. Later, gatling became the first man to go into space. Stepping into the 2 1 century, Yang Liwei traveled in space, bringing China's space industry into a new era. Nowadays, crossing the atmosphere into space has become our dream.

Comments on the second lesson of Tiangong Classroom 10 I watched the live lecture of Tiangong Classroom this afternoon. In this class, I experienced the magical phenomenon of outer space, which amazed me. Teacher Wang Yaping showed us many amazing phenomena. For example, Teacher Wang Yaping gave a hard twist to a towel covered with water, but the water did not fall to the ground, but firmly wrapped her hand, like a pair of gloves, which was incredible.

Comments on the second lesson of Tiangong Classroom 1 1 The development of Tiangong Classroom gives us a good opportunity to "get out of the house" and let us know more about space during the epidemic. The interesting lectures given by three astronauts also aroused our interest in exploring the mysteries of space. I believe we will fly our dreams with the spacecraft with a vision for the future!

What fascinates me most is the experiment of water-oil separation. On earth, water and oil are separated quickly, but in space, water and oil can only be separated by centrifugal movement, which makes me interested in doing experiments in space. In the interactive session between heaven and earth, the astronauts answered some questions raised by the students on the spot, which made me more curious about space and proud of the strength of my motherland!

Lesson 2 Review of Tiangong Classroom 13 Today, under the guidance of the teacher, we watched Tiangong Classroom. I think the maglev balance and camera positioning function of the microgravity platform are great. In daily life, there are many such rigorous and scientific experimental phenomena and knowledge, which require us to make great inventions like Einstein, discover the law of gravity like Newton, and let others see our success!

Comments on the second lesson of "Tiangong Classroom" 14 "Tiangong Classroom" made me feel the power of my motherland again. This space trip not only created a new record for China people to stay in space, but also conducted many space science experiments and technical experiments, which produced high-level scientific achievements. "Flying dreams never lose weight, and scientific dreams have unlimited tension." As long as you dare to dream and pursue your dreams, you can build your own dream spaceship with wisdom and sweat and fly to the vast starry sky!

Lesson 2 Reflection in Tiangong Classroom 15 The earth is the cradle of human beings, but human beings cannot stay in the cradle all the time. China started late in space engineering, but with the unremitting efforts of generations of astronauts, China's space industry came from behind. This space lecture is interesting and informative, and the signal transmission is clear and smooth. This is a perfect demonstration of China's scientific and technological strength, and China's space flight is wonderful.
