After reading a work, it can give us a lot of inspiration, so we should seriously think about how to write a review. Let's refer to how to write feedback. The following is a 600-word model essay (6 general remarks) about the feedback from the second lesson of Tiangong class. For reference only. Welcome to reading.
The second lesson in the Tiangong classroom, 600 words, 1, "Flying dreams never lose weight, and scientific dreams are infinitely tense." The vast science is mysterious because it seems to soar in the universe; But it is kind, because it is always with us.
At 3: 40 pm on March 23, the exciting "Tiangong Classroom" began. The astronauts Zhai Zhigang, Wang Yaping and Ye Guang Fu of Shenzhou XIII gave us an interesting physics lesson. Space "ice and snow", liquid bridge demonstration, water-oil separation, space parabolic, these fantastic and mysterious experiments, which we have never touched before, think they are very fantastic things, but in their works, they are so wonderful and interesting that they deeply attract us and inspire our desire to further explore science. Their powerful language and the audience's earnest study highlight the new look of the country's prosperity. Science is not a very abstract and rigid thing, but also a very interesting and attractive activity. It is precisely because of people's fascination with science and constant exploration and pursuit that China has made brilliant achievements in the great space industry.
"Sit on the floor, travel 80,000 miles a day, and look at thousands of rivers." From "Two Bombs and One Satellite" to "the Goddess Chang'e flying to the moon", then to "Beidou", and from "Tiangong" to Range Rover, China's spacecraft pierced the sky again and again and flew to the vast universe. This is a successful exploration of cosmic science by human beings! I think, as China people, we are most proud of turning the romantic and beautiful myth imagined by the ancients into reality through science and technology, and turning "dare" into "breakthrough". We have to feel that the rapid development of science and technology in China has brought us convenience and pride. There is a red flame in the infinite universe, which is the most exciting and proud of all China people.
This "Tiangong Classroom" not only made me interested in scientific experiments, but also made me feel the "magic power" of science. The field of science is full of fantasy and mystery, just like space, which makes us full of yearning and curiosity; In daily life, science often brings us all kinds of conveniences and enjoyment; In repeated experiments and explorations, all the new discoveries are so delightful and fascinating.
We landed on the moon and explored Mars. There are more and more China people in space. As of February 3, 2022, the total flight mileage of Tianwen-1 probe has exceeded 450 million kilometers, which is about 65.438+700 million kilometers away from the earth. China's science and technology will get better and better. At the same time, we will continue to work hard, go forward bravely, and strive to leave a more brilliant mark in space!
The second lesson of the Tiangong Classroom is 600 words. 2 Compared with the previous Tiangong Classroom, I have a deeper feeling. This is the second interactive live broadcast of popular science between "Heaven" and "Earth". With this flexible and close interactive form and interesting and vivid content, Tiangong classroom has immersed every student in this visual feast, taught more scientific truths to students more effectively, and ignited the interest and enthusiasm of young people in exploring the universe and science.
We can see such a lively and interesting Tiangong classroom and appreciate the different mysterious world in space, which is completely supported by the strength of China University of Science and Technology. From the flying dream of the ancients to shenzhou spaceship soaring in the universe; From Chang 'e's lunar exploration to the completion of the space station. China's scientific and technological strength continues to advance, major scientific and technological achievements are constantly emerging, and scientific and technological innovation is increasingly active, which has injected new vitality into high-quality economic development and is second to none in the world. After watching the Tiangong class, my cultural self-confidence and confidence have been strengthened.
Great country, great and powerful. Science and technology take off and shine brilliantly. The five-star red flag in the space capsule makes the people of China feel extremely cordial, and the red flag inserted in outer space makes us feel proud and proud. However, in the boundless and vast universe, there are more unknowns waiting for us to explore and more mysteries waiting for us to answer. Every star in space and every drop of water in the sea carries the dreams of countless teenagers in China.
"The people have faith, the country has strength and the nation has hope." Young people in our new era should strive to improve their scientific literacy, strive to be the pillars of the country, contribute to the scientific and technological development of the motherland, and explore a more magical and magnificent world with the fighting spirit of youth!
Today, the space teaching in the Tiangong classroom officially begins, which is a feat of China's space industry. It not only indicates that China has been able to skillfully use manned space technology, but also means that China's space science and technology has once again extended an olive branch to the field of education. This time, China astronauts passed on scientific knowledge in distant space and showed the world the charm of the universe with various space experiments, which aroused my interest in mysterious space.
However, teaching scientific knowledge in person by giving lectures in space can only be a feat that human beings can accomplish in modern times. 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 "teachers are the most glorious profession under the sun", but Zhai Zhigang, Wang Yaping and others have sprinkled the glory of this profession into space, so that the whole universe is 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. And I also hope that this space exploration can take us to more distant places, so that more places can hear the "good voice of China."
I learned a lot from this space lecture. Let's be less careless in our daily study, be more attentive, and take the baton of China's space age with genuine talent and practical learning.
As we all know, China is now vigorously promoting the development of the space industry. That was not the case. The space station in our country was built and the Tiangong class began. Just today, another Tiangong class was held in Tianhe core cabin. I was deeply touched after reading it.
Today's Tiangong class starts at about 3: 40 and ends at 5: 00. The main contents are as follows: 1. There are experiments: liquid bridge experiment, "ice and snow" experiment, water-oil separation experiment, space parabolic experiment, introduction of two scientific facilities and students' questions. Among them, the "popular king" Bing Dundun also participated in the space parabolic experiment!
There are many experiments in this Tiangong class, but what I like most and am most interested in is the water-oil separation experiment and the liquid bridge experiment.
First of all, talk about the water-oil separation experiment. As we all know, on the earth, because the density of water is greater than that of oil, oil will float on the water surface. But space is a microgravity environment, so if it is still, water and oil will be evenly mixed together, which is amazing!
So, is there any way to separate water from oil in space? The answer is yes: yes! A student at the main venue in Beijing put forward a method: isn't it ok to spin the bottle quickly? It turned out that at the beginning of the Tiangong class, two hosts did an experiment: one put the bottle on the shelf, and then he quickly rotated the shelf, and there was not a drop of water in the bottle! Teacher Wang Yaping did it according to his method, and the result was separation of water and oil! It seems that an ordinary scientific conclusion can also work miracles!
Let's talk about the liquid bridge experiment first. Teacher Wang Yaping took out two glass plates, and then "poured" fresh water on them, and then the two were butted and separated to create a liquid bridge! It turns out that this is the dual function of microgravity environment and surface tension of water. This is amazing!
Yes, the Tiangong classroom is really wonderful, but if generations don't work hard and pay, what's the use of the best blueprint? I guess it's just a paper plane for fun. It is precisely because of the efforts and efforts of generations that this visual feast will be held. Look, because of their contributions, the dream of flying to the sky came as promised: "Chang 'e" to explore the moon, "Tian Wen" to explore the fire, "Tiangong" laboratory ... When the International Space Station refused to let us join, didn't we also set up our own space station? We can do what foreigners can do: we can do what they can't do!
Finally, with a sentence at the end of "Pilotage": The great China * * * production party is in its prime, standing on the journey of the new era, standing on the journey of the new era!
Last year, at 0: 23 on June, 202 1 Beijing time, the Shenzhou XIII manned spacecraft carried three China astronauts, Zhai Zhigang, Wang Yaping and Ye Guangfu, into space. They will work and live for six months. Now, Chinese astronauts are spreading scientific knowledge in 300 kilometers of space. After eight years, China astronauts once again taught in space. Today, the lecturer of Space is still Wang Yaping, but the difference is that the platform of this class is bigger. I am sincerely proud and happy for China's independent China Space Station and the development of China's space industry.
People often say: "Sit on the floor, travel 80,000 miles a day and look at thousands of rivers." China people have been dreaming of space for thousands of years. From the fairy tale of the Goddess Chang'e flying to the moon, to the meeting of cowherd and weaver girl on the magpie bridge, to the feat of flying, all of them show the Chinese nation's yearning for flying into space and roaming the universe. It indicates that China has been able to skillfully use manned space technology, and it also means that China's space science and technology has once again extended an olive branch to the field of education. It embodies the concept that the space station serves the national education, shows the strong national strength of China, and stimulates students' yearning for space and enthusiasm for learning scientific and technological knowledge. The great aerospace spirit and scientific spirit have taken root in more people's hearts.
In this space lecture, we carried out a series of experiments, which were very interesting and inspired my space dream again. I will always remember what Teacher Ye said, "The purpose of building the space station is to carry out large-scale scientific experiments, so more researchers will come to the space station for experiments, so students are very welcome to come to the space station for experiments in the future." I look forward to one day, I can stand in their team.
The second lesson in the Tiangong classroom, 600 words, stars flashing at 6 o'clock, gathered into a deep and vast sky. In the supreme place of the universe, there is a space station, which is full of bright light. A cosmic lesson will be held in that small space station. ...
"Please look at the water polo in my hand now ..." As Wang Yaping explained, a crystal clear water polo was instantly filled with snowflakes and turned into a small "ice hockey" with white light. This is the first activity in the course-the experiment of "ice and snow" in space.
Then there is the experiment of water-oil separation. Small transparent bottles filled with water and oil were also carried out in the China Science and Technology Museum on land. We found that water and oil are separated slowly, but in the space station, water and oil are still mixed together and only separated by centrifugation. I can't help but sigh: it's amazing! There are so many mysteries in the universe that we will explore them one by one.
Finally, the ice mound, which is now a household name, did not fall vertically as it did on land, but moved in the original direction at a constant speed and slowly reached Mr. Ye's hand.
Now that we have our own space station, astronauts share some strange things that we don't know. The exploration of space has proved the strength of a country, and I have seen the strength of our motherland's science. I will also contribute to our motherland in the future, because this is my Chinese dream, and this is also the space science dream of all China people. We should study harder and become the pillars of the motherland.
Looking up at the night sky, the stars are embedded in the dark blue night. The Milky Way, like a faint white belt, spans the starry sky, and one of the stars shines especially brightly. I know I am one step closer to my dream. ...
