Wang Yaping Tiangong Classroom 1 Comments on the Second Lesson
A "space lecture" touched the hearts of countless people in China. If we are more proud of the success of the launch and recovery of manned spacecraft in the past and in the past, what we are proud of now is the vivid and beautiful display of space technology and experimental details. What did the space class bring us?
The first is the influence on teenagers' scientific exploration spirit. Aerospace science and technology can strengthen the country, revive national prestige and bring national cohesion, which may be somewhat abstract in the past. However, in the face of the scientific demonstrations in the Tiangong class again and again, people will sincerely lament the strength and advancement of space technology, and national pride will arise. Tiangong classroom not only shows young people scientific principles and miracles, but also provides the most vivid opportunity for patriotism education.
The second is the impact on the scientific literacy of all citizens. Interesting "teaching in space" makes some boring physical formulas come alive, visible and tangible. A drop of water contains many scientific principles. The weighing of an astronaut involves simple application of science and technology, which not only interests young people, but also makes adult audiences like science better. Aerospace science and technology is not empty and difficult to solve, but ultimately serves scientific life, which is very beneficial to cultivating the scientific literacy of the people.
The third is the influence of space technology on changing life. There are many civilian technologies in space science and technology. Every progress and development of space science and technology will greatly promote the development of civil science and technology. Electronic thermometer, dried noodles, diapers, heart pumps and liquid supplements are all civilian products of aerospace science and technology. Nowadays, "space vegetables" are widely planted to serve human life, and space science and technology have contributed greatly.
The fourth is the influence on interesting education. I believe that after watching this lecture in space, even students who are unwilling to learn scientific knowledge will find science so interesting, vivid and practical, from water drops to weightless simple pendulum motion, from the axis motion law of gyro to the tension and capillary phenomenon of liquid. If we can have more fun, intuition and vividness like "teaching in space" in our usual educational activities, we can not only learn scientific knowledge from boring to interesting.
In short, in the face of the vast universe, we are all students and can't take it for granted. In the past, many of us thought that astronauts must think the sky was blue. Through this "space lecture", we know that the space seen by astronauts is a very bright black sky, and technology will always be a magic weapon for a country to be invincible. Space technology is not only powerful, but also related to the scientific and happy life of our family. The Chinese dream is down-to-earth, and the technological dream has unlimited tension!
Comment on the second lesson of Wang Yaping's Tiangong No.2 Classroom
In ancient times, people always wanted to launch some detectors into space. However, a single function cannot complete people's exploration of space. So, people began to think of ways: how to let people go to heaven! This time, the "Long March II rocket" and "Shenzhou XII spacecraft" were used.
Last time we went to space, we spent a lot of money. If we only go up for three or four hours and think it is not cost-effective, we want to build a place like a hotel where astronauts can live, that is, the space station.
According to the plan, Space Station 1 consists of five parts: the first part is a "manned spaceship", which mainly carries astronauts; The second one is the "Quest Experiment Module", which is used to do some experiments that cannot be completed on earth; The third is the "dream experiment module", which is similar to the "real experiment module" and is also used for experiments. The fourth is the "Tianhe core cabin", where Chinese astronauts live; The fifth type is "cargo ship", which is mainly responsible for transporting all kinds of materials. However, this plan has not been completely completed. At present, the space station has only two parts: Tianhe core cabin and cargo spaceship. It is said that in 2022, the space station will be completed.
Legend has it that there is a Guanghan Palace. On the moon, our space station floats in space. The sun radiates "energy" to the earth every day, but when we bask in the sun on the earth, the sun is far away from us and the danger is very small. Astronauts who spend too much sun in space may get cancer, so it is stipulated that the space station should not be higher than the earth 1000 km. After considering various factors such as funds and experimental results, scientists finally built a space station 400 kilometers away from the earth.
On the earth, everything you throw will fall to the ground. This is Newton's "gravity". If we stand on the flat ground and throw things, we will fall down; Then if we "throw" the spaceship at a very fast speed, it will fall to the same extent as the radian of the earth, and then the spaceship can fly along the earth. The space station flies very fast, and it can circle the earth in an hour and a half.
Since ancient times, it is impossible for people to see the whole sky on the earth. If you can see clearly from the space station, you can see far, because you stand tall.
In the space environment, we can do some experiments that we can't do on earth, such as finding some chips smaller than mobile phone chips, or things that can change color in some environments.
There are several small goals for astronauts to go into space this time: to live for about three months; Debugging all kinds of equipment; Do some incredible experiments; Get out of the cabin and see the whole picture of space and space station.
China's space station allows us to explore more mysteries of space.
Wang Yaping Tiangong Classroom Lesson 2 Review 3
I like the beautiful Chinese knot hanging on the Tiangong space station, facing the bright five-star red flag. Such a space station is the most beautiful scenery in space, and it also makes us feel more cordial.
In space, you should control your body to adapt to weightlessness and swim around like a fish. Food was originally prepared in advance on earth. Cultivating space plants is an important task in this mission.
In space, although you can't take a hot bath like on earth, there is no problem in washing your face and hair. Researchers have specially developed a decomposition shampoo-it can not only wash your hair clean, but also save water. The water in the space station is very precious, so we should save water as much as possible.
Sleeping in the space station is more interesting. As long as you have a sleeping bag, it is generally required to be fixed on the bulkhead, but you can sleep anywhere, such as the ceiling, as long as you like.
There are also many leisure activities in the space station, such as video calling with family members, enjoying the beautiful earth at sunset from the porthole and doing morning exercises. Morning exercise is a traditional fitness program in China-Tai Ji Chuan.
The most important and exciting thing is extravehicular activity. Put on your "flight suit" and go outside the cabin through the airlock. Through the joint efforts of the ground dispatcher and the cabin companions, the related tasks were successfully completed outside the cabin.
There are also many happy events in space: the rice planted is heading, the space courier is ushered in, and new partners are ushered in for work handover. After staying in space for three months, I will bid farewell to the Tiangong space station and return to Earth soon. I am very excited to meet my relatives on earth soon.
Space itself is fascinating. In the vast universe, every time there is a five-star red flag, every Chinese son and daughter feels cordial and proud!
Comment on the second lesson of Wang Yaping's Tiangong No.4 Classroom
Struggle is the wing of a round dream. Generation after generation of astronauts have worked hard in the "experimental field" of aerospace, their hearts are full of latitude and longitude, and their feet are embedded in the vast sky. They struggled hard on the basis of poverty, strove forward in repeated experiments and pursuits, pursued Excellence under the challenge of Excellence, dared to break through difficulties and bravely opened up new roads. Astronauts learn experience and excellent skills in strict, systematic and comprehensive training. Flying in the sky and getting out of the cabin requires a solid foundation, excellent psychological quality and strong physique. Hard training in summer and winter gives them super willpower and self-confidence. For the great aerospace industry, astronauts and astronauts regard hardships and twists as a "ladder" for their career development, forge their backbones with ambition, accumulate strength with backbone, and achieve higher-level innovation and breakthrough in the aerospace industry through continuous struggle.
From the successful launch of Shenzhou I to the space trips of Shenzhou 5, Shenzhou VI and Shenzhou VII ... China's manned spaceflight project has achieved fruitful results. On the road of "chasing dreams", every time is a brand-new journey, and every time is an unprecedented challenge. Of course, unprecedented challenges and difficulties have also created unprecedented heights. Mr. Lu Xun once said: "In fact, there is no road on the ground. If there are more people walking, it will become a road." The road comes from two feet and is developed step by step. Since the development of China's space industry from 65438 to 0956, self-reliance and independent innovation have been consistent in the development, which is the core competitiveness to promote the development of space industry. It is bound to take detours to take the road that predecessors have not taken, and it is bound to encounter setbacks to break through the hurdles that predecessors have not taken. Only by being a pioneer can you become a pioneer. Only by daring to break through can we break a new world and seize the "new highland".
Great cause breeds great spirit. Looking back on the development history of the aerospace industry, whether it is the successful launch of "Dongfanghong-1" or the great achievement of Shenzhou manned spaceflight project; Whether the Beidou satellite navigation system is completed in an all-round way, or the "Chang 'e" flying to the moon and "Tian Wen" exploring fire, from bold ideas to successful practice, China's space strength that keeps pace with the times has been demonstrated. China's space industry has gone from a difficult start to a arduous journey and then to brilliant achievements, leaving behind China and China in the vast space, China spirit and China strength in the development of space industry. This spirit and strength will surely lead the 65.438+0.4 billion China people to work hard with one heart and one mind, forge ahead on a new journey and dream of a new era.
On the second lesson of Wang Yaping's "Tiangong No.5 Classroom"
"Space teaching" has opened up a new way of face-to-face teaching of science and technology with students. This is a brand-new educational reform, which will inevitably inspire students to face more teaching methods in the social field. For example, writers and students teach face to face, for example, entrepreneurs and students teach face to face, and so on. Running education well is not only the responsibility of the school, but also the responsibility of all fields of society. We all know this responsibility, but it is not enough. Today, space teaching has taken a big step. I firmly believe that this great step will surely lead to more fields of social teaching, which will surely become a brand-new content of education reform in China, and the sacred duty of social education will surely be well implemented.
"Space Teaching" was successfully taught by a speaker and two people. This is a pioneering work, breaking the tradition of attending classes alone. In my opinion, this teaching method should be popularized in local interviews. On the one hand, there are many students in our class and the teacher is very tired. On the one hand, multi-person teaching is more vivid, three-dimensional and diverse, which will inevitably create a more substantial learning atmosphere for students. This is a pioneering work of educational reform.
"Space teaching" is unique in teaching with immersive feelings. Teachers are integrated with knowledge and environment. Teachers are immersed in teaching, students are immersed in learning, and the image synthesis of teachers, classrooms and knowledge is truly achieved. As a classroom for ground teaching, we should learn from it and create a classroom according to the on-site environment, current teaching content and teachers' personality. Only a good classroom is the most beautiful classroom.
"Space teaching" is the crystallization of high technology and the achievement of educational modernization, which will certainly inspire our educational Chinese dream to be more brilliant.
I hope there will be more such space lectures in our Chinese dream education, such as lectures in factories, shopping malls, warships and airplanes. The Chinese dream is a concrete dream of three-dimensional, socialized, modernized, visualized, diversified and networked education.
