After watching the Tiangong classroom, 1 When the astronaut taught us space in the Tiangong classroom, did you know her efforts for her dreams? They are celebrities. They are just ordinary people who struggle for their dreams and insist on making their lives different. Although the dream is beautiful, if there is no courage and action to persist, then that kind of beauty can only stay in the dream and will not become a reality today.
This reminds me of the days when I was studying in the Children's Palace. I like inventions very much. Although my father supports it, my mother thinks that "invention can't be eaten as a meal" and doesn't approve of my study of invention. I still remember my father saying, "don't worry, son, you have to learn." This is your dream. Even if 10 thousand people object, it is right to stick to it. " This sentence of my father really coincides with what Mr. Wang said, and it also strengthened my heart to learn painting. I think everyone has their own dreams. My dream is to be a painter, but Sister Li Juan has a pair of flying wings. I admire her courage to jump bravely under the blue sky-because I am afraid of heights.
Their deeds tell us a truth-dreams are motivation, and dreams with motivation can succeed; If you have a dream, you must stick to it. Only by sticking to it can you succeed. Only when you dream can you be brilliant, and only when you are brilliant can you succeed.
Dreams will not abandon us, only we can abandon ourselves. No one can succeed casually, so, although there will be all kinds of hardships, multiple tests and even tears in the journey to realize our dreams, it will bring us a lot of pain, but if we give up, there will be nothing. Therefore, no matter how hard, painful and tired you are, you must persist. Because persistence is the best way to dream.
I also have my own dream-to be an inventor. Although this dream seems ridiculous, because more and more people are playing with inventions, they think that inventors are so much. Or some people think that inventors are just redundant, unable to keep pace with the times and create social value, but I don't think so.
I like to appreciate those useful inventions with appreciation eyes and happy mood, to understand what happened in the past history, to listen to the voices of the ancients, and to pursue the traces they have traveled. Although there are many difficulties to overcome, I will stick to it as always, just like them.
Dream is a key. She can't open all the locks, but she 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 dreams. Life without carving is incomplete, so, my friend, let dreams carve our lives and lead us to success!
If you want to give up, please hold the key in your hand and keep your faith-I must open that lock!
China Manned Space Engineering Office announced that in order to give full play to the comprehensive benefits of China Space Station, China's first space science education brand "Tiangong Classroom" will be officially launched, and the first space teaching activity of China Space Station will be broadcast live to the whole world in the near future.
I am very excited to see this news, because I can see a series of wonderful phenomena of object movement in space microgravity environment. This reminds me of the 20 13 space lecture.
In just 40 minutes, the astronauts only used five simple experiments to let everyone know more about the changes of objects and their principles in weightlessness. There are also water film experiments and gyro experiments, which let me know that I can do many incredible things in weightlessness, among which water polo experiment is the one I am most interested in! First, put a ring about the size of a magnifying glass into a drinking tap water bag, and it will become a water film after taking it out. Then, water drops will be continuously injected into it, and slowly the water film will become a crystal clear water ball. If you insert the needle into the water polo on the ground, it goes without saying that the water polo will explode. However, it is a miracle that we can inject ink into the water polo with a needle in space, but the water polo is "unscathed"! This made the audience dumbfounded.
Armstrong, the first man to land on the moon, once said: One small step for me, one giant step 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 lecturers and feel the fun of space.
On February 9th, 65438, organized by teachers, students in our school sat in the classroom this afternoon and watched the first lesson of Tiangong Classroom through multimedia. The first lesson of "Tiangong Classroom" was in China Aerospace. Tiangong class allows us to experience the fun of exploration, perceive the mysteries of the universe and interact with the world.
"Tiangong Classroom" begins with wonderful space. This paper describes the basic necessities of China astronauts in the space station, and introduces the internal design and functions of the spacesuit to us in detail. The role of penguin suit is to reduce muscle atrophy and cardiovascular function. Then the research on cell growth and development under weightlessness is described, and the myocardial cells are explained in detail. Cells are amazing in space, jumping and flashing under fluorescent microscope are very shocking. Cardiac muscle cells are contracting.
When students ask questions, they ask different questions. The first student asked Mr. Ye Guangfu and Mr. Wang Yaping in the space station: "Can you walk freely in the space station 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 can't walk like people on the ground. They always float around. In the process of rotation, the upper body turns right, the lower body turns left, the upper body turns left, and the lower body turns right. Blowing and other actions can't make them circle in the space station. This is what teacher Ye Guangfu showed us, but when the arm rotates greatly, we can make them turn around. The second classmate asked Mr. Wang Yaping, "Can the domestic water in the space station be recycled?" Teacher Wang Yaping gave us the answer. Because they use treated raw water, they cannot recycle it. Water is buoyant on the ground. If you put a ping-pong ball in a glass and press it down, it will keep coming to the surface. But in the space station, table tennis did not surface, but was crushed and sank to the bottom. Teacher Wang Yaping explained to us that buoyancy almost disappeared in the space station.
The water film experiment was completed by Mr. Wang Yaping and Mr. Ye Guangfu. This experiment opened the flower space made by Mr. Wang Yaping and his daughter. Then, Teacher Wang Yaping poured water into the water film to form a big water polo. Looking through the water polo, Mr. Wang Yaping is an inverted image, which is formed by convex lens imaging. Later, Teacher Ye Guangfu removed the small bubbles from the water polo and injected a big bubble into the water polo. Through the water polo, Teacher Wang Yaping can see two images, one is right and the other is wrong. Teacher Wang Yaping took this opportunity to ask us: "Why are there two images, one positive and the other negative?" ? That's because the water polo is divided into two parts by bubbles. "Teacher Wang Yaping and Teacher Ye Guangfu also conducted effervescent tablet experiments, and the pictures were spectacular. There are several students from Nanning, Macau, Wenchuan, Sichuan, Beijing and so on. They asked teachers Ye Guangfu and Wang Yaping different questions, and teachers Ye Guangfu and Wang Yaping also answered their questions one by one.
Finally, three students expressed their feelings. The first student thought the camera imaging was very shocking. The second classmate suggested that when the space station wants to turn, it should be possible to turn it with a fan; The third classmate said that astronaut teachers have to overcome many difficulties in the space station and how difficult it is to shoulder heavy responsibilities. I hope they can be as great as astronaut teachers in the future.
In this regard, the first space lecture of China Space Station was successfully concluded.
My ideal is blue, but I added a bright red, which is the color of the national flag. I put blue on my body and embroidered red on my chest.
Reflections on Watching the Tiangong Classroom Part 3 This "Tiangong Classroom" is mainly for teenagers and adopts the interactive mode of heaven and earth. Wang Yaping, astronaut of Shenzhou XIII, served as the main teacher, while Ye Guangfu and Zhai Zhigang served as teaching assistants, giving lectures on the spot.
Three "space teachers" showed three interesting scientific experiments for teenagers: table tennis experiment, water film experiment and effervescent tablet experiment. The students also carried out the above experiments on the ground. Because the weightlessness environment in space is completely different from the gravity environment on earth, they present completely different experimental phenomena, which arouse people's deep thinking.
For example, if students immerse table tennis in water, the ball will float on the water because of buoyancy. But in space, after the table tennis is immersed in the water, the ball is suspended in the water and will not fall even if it rotates back and forth in the air. According to Wang Yaping, this is because the buoyancy will disappear in the space station, so the ball will not be affected by buoyancy.
Let me start with 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 polo like a convex lens. When the origami flowers were put in, the flowers in the water polo opened, which was amazing. This is because the surface tension of water in weightless environment shows great strength, so water will not flow downwards, thus forming water polo. Inject bubbles into the water polo, which will divide the water polo into two parts, forming a positive image and a negative image. But Wang Yaping didn't tell us directly, but caused us to think, let us actively explore and discover the mysteries of science.
This lecture in the space station has greatly shocked me, greatly increased my interest in science and planted the seeds of exploring the universe in my heart.
In full bloom Flowers in the water are like the prosperity of the motherland, blooming their own brilliance, warm and beautiful. In 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 roaming in space and every drop of seawater in the sea carries the dreams of countless teenagers in China.
This is the second time that "Sky Class" has been held in China Space Station. We firmly believe that in the future, China 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 the great scientific spirit. Let's 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 expectation and felt life in space for the first time. I'm very excited.
First of all, I saw that they didn't use our ordinary cups when drinking water, but used a bag with a straw on it. I also found that they didn't drink it at first, but squeezed the water out first. Water can float in the air, and you can drink it into your stomach with only one mouth. I learned that everything is floating, because there is no gravity in space.
Subsequently, they used the tension of water to make water in the water film into water balloons. The experiment of convex lens imaging was explained to us, which made us understand the imaging principle of convex lens inversion.
Through the study of this Tiangong class, I learned a lot of space knowledge. Their spirit of daring to explore deserves our admiration! I will study hard and use my scientific and cultural knowledge to contribute to the aerospace industry of the motherland in the future!
At present, we are facing a great change that has never happened in a century and have begun a new journey of building a socialist modern country in an all-round way. Opportunities and challenges coexist, and difficulties and hopes coexist. On the one hand, young cadres should take over the "baton" of the revolutionary cause, refine experience, enlighten wisdom, forge ahead, learn to be an old ox, carry forward dedication and conscientious sense of responsibility, and shoulder the heavy responsibility entrusted by the new era. On the other hand, we should study hard, increase our skills, take active actions, do a good job in the "relay race" of national rejuvenation, and achieve good results for the younger generation. The vast number of scientific research workers should further carry forward the aerospace spirit, climb the peak of science and technology forever, and take the long March in the new era.
Carry forward the patriotic spirit of "serving the country when you grow up". In the early days of the development of China's space industry, many successful and talented scientists gave up the favorable conditions abroad and returned to the motherland without hesitation. Many developers are willing to be unsung heroes, unknown, silent dedication, and some even give their precious lives. They wrote touching poems with their own blood and lives, dedicated them to the motherland and the people, and sacrificed them. Scientific research talents in the new era should learn from the older generation of scientists, strengthen the idea of scientific and technological innovation and serving the country, integrate the pursuit of career into the needs of the country, inherit the tradition of patriotic dedication of predecessors, take the needs of the country and the nation as the research orientation, and realize the perfect integration of individuals, careers and the country on the road of serving the country through science and technology.
Carry forward the struggle spirit of "tempering" In the vast Gobi and sparsely populated ravines, the older generation of researchers overcame all kinds of unimaginable difficulties and obstacles. They used limited scientific research and experimental means, relied on science, worked hard and innovated, broke through one technical difficulty after another, and achieved great victory in the cause of "two bombs and one satellite". In this era, we are undoubtedly lucky, both living environment and scientific research conditions are far better than the older generation of scientists. Contemporary researchers follow the example of the older generation of scientists, vigorously carry forward the spirit of self-reliance and hard struggle, work hard in their respective fields and create new achievements.
Carry forward the unity spirit of "everyone gathers firewood and the flame is high". In the extraordinary process of developing "two bombs and one satellite", thousands of scientific and technical personnel, engineering and technical personnel and logistics support personnel from all regions and departments across the country have United and cooperated, and Qi Xin has made concerted efforts to form a mighty team to March to the peak of modern science and technology. With their brilliant achievements, they have added a dazzling page in the history of Chinese civilization creation. Scientific research is a complex and arduous group labor, and the interaction between people in scientific research activities directly affects the scientific research cooperation and the completion of scientific research plans. The majority of scientific research workers should firmly establish the awareness of the overall situation, cooperation and service, focus on the same goal, and cooperate with each other while giving full play to their respective strengths.
At 0: 23 10 on June 6th, Beijing time, the Long March II F- 13 carrier rocket carrying the Shenzhou XIII manned spacecraft was launched at Jiuquan Satellite Launch Center. The Shenzhou XIII manned spacecraft was successfully separated from the rocket and entered the scheduled orbit, and three astronauts, Zhai Zhigang, Wang Yaping and Ye Guangfu, were successfully sent into space. Three astronauts rushed to the sky with the expectations and blessings of all China people, and went to China Space House in the vast universe.
Although the launch time was in the early hours of the morning, the news of "complete success" came out, and the Internet was full of jubilation. Countless netizens were waiting for this moment and were full of feelings about the success of the launch.
According to the "convention" that China Aerospace never stops, Shenzhou 13 will also achieve several "firsts": radial rendezvous and docking with the core module; The first stay in orbit is 6 months, which is also the normal stay period of astronauts during the operation of the space station; For the first time, it was transferred from a rescue ship to a formal mission ship.
In addition, compared with Shenzhou 12, Shenzhou 13 has many special features. For example, after the docking of China Space Station, the space station will realize the combined operation of core module, two cargo spacecraft,/kloc-0 manned spacecraft and four aircrafts. Spacecraft and rockets carrying out missions are also directly transferred from the backup state of emergency standby to the launch state at the launch site.
Moreover, after the Shenzhou-13 mission, all the functions of the space station mission standard manned spacecraft will be verified in orbit, which fully meets the needs of supporting the subsequent construction and operation of China's space station, and also marks the official transfer of the project from the key technology verification stage to the on-orbit construction stage, which is of great 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 of outer space at an increasingly fast frequency. After several generations of efforts and dedication, we can proudly say today that China has become an important "player" in world space exploration, and there will be more and more human footprints from China in space.
Despite the technical shock, today's China Aerospace has become more and more calm, confident, warm and romantic, and has a unique Chinese charm.
For example, the flight crew of Shenzhou XIII included Wang Yaping, the first female astronaut of China Space Station. Before leaving, she specially sent a circle of friends who had been on a business trip for half a year, and her humorous expression revealed a sense of confidence. At the scene of the war, Wang Yaping's daughter came to see her mother off and shouted "Come on, mom". This scene touched countless people, and "Mom started to pick stars for you" quickly became a hot topic on the Internet.
The Shenzhou XIII mission will last for half a year and will span the China Lunar New Year. The astronauts' first Spring Festival in space has also attracted much attention. Previously, when the Tianzhou-3 cargo spacecraft sent a "space express" to the space station, it had already prepared Spring Festival supplies for astronauts. At that time, astronauts will also celebrate the Lunar New Year in space with all China people. These meticulous and ingenious arrangements make the "scientific narrative" of aerospace hardcore reveal deep humanistic feelings.
Now, Shenzhou XIII has officially started its space journey. We wish the astronauts a successful mission, and we also believe that China Aerospace will bring us endless surprises and go further with our dream of becoming a great country.
Today, we attended the first space lecture in the Tiangong classroom of China Space Station. The astronauts Zhai Zhigang, Wang Yaping and Ye Guang Fu of Shenzhou XIII gave us a lively and interesting physics lesson.
First of all, Mr. Wang Yaping showed us the main structure of Tianhe core cabin, and successively showed us the residential area, sanitary area and space kitchen. Later, the teacher also introduced the use of space treadmills, space bicycles, "penguin suits" and other sports equipment, and explained the importance of exercising in space: the space station has almost no gravity, and the microgravity environment will make people's blood swell, bones loose and muscles atrophy, so it is necessary to keep exercising to stay healthy. Teacher Ye Guangfu also showed us how to walk and turn around in space, which made us better understand the life of astronauts in space.
Then, the most exciting space experiment. Three teachers demonstrated the space cytology experiment, buoyancy experiment and effervescent tablet experiment, among which the water polo imaging experiment impressed me the most. Teacher Wang Yaping made a water film first, and then slowly filled it with water. Due to the strong surface tension in microgravity environment, the water film has become a crystal clear water ball. When the teacher injected another bubble into the water and put his face close to the water polo, two images appeared in the water polo, one positive and the other negative. The teacher explained that this is because the bubble divides the water polo into two parts, so that it can be imaged separately. After such a unique "Tiangong Classroom" ended, I finally understood the sentence "Space teaching is the most vivid practical case in physics classroom".
Just as Teacher Wang Yaping sent a message to our teenagers at the end of the course, "We are flowers in bud in the motherland, and we hope our dreams will bloom in the vast space", our task now is to study hard scientific and cultural knowledge, serve the motherland in the future, and make our modest contribution to the aerospace industry and scientific and technological development of the motherland!
"Tiangong Classroom" finally met us. Today, the school organized us to watch this exciting program. This time, the class moved to China people's own space station, and three astronauts in Tianhe core cabin brought us a unique "space teaching".
202 1, 10 At 0: 23 on June 6, the Long March II carrier rocket carrying the Shenzhou XIII manned spacecraft was accurately ignited and launched at Jiuquan Satellite Launch Center according to the scheduled time. About 582 seconds later, the Shenzhou 13 manned spacecraft was successfully separated from the rocket and entered the predetermined orbit, and three astronauts, Zhai Zhigang, Wang Yaping and Ye Guangfu, were successfully sent into space. The astronauts are in good condition.
"Flying dreams never lose weight, and scientific dreams have unlimited tension." Eight years ago, Wang Yaping, the "space teacher", left a deep impression on everyone. Now she is once again on a trip to space, and will become the first female astronaut in China and the first female astronaut in China. Being in space, facing the earth and teaching the people of the earth, Wang Yaping is the first space teacher in China, showing the demeanor and demeanor of a space power.
This space teaching activity is conducted in a way of interaction between heaven and earth. The main classroom on the ground is located in China Science and Technology Museum, and the sub-classrooms on the ground are located in Nanning, Guangxi, Wenchuan, Sichuan and Macau. Three astronauts introduced and demonstrated the working and living environment of the China Space Station on the space station, and demonstrated the cytological experiment in microgravity environment. The cells kept beating under the fluorescence microscope. The microgravity environment is hard to get on the earth, and the experimental phenomenon is more direct and intuitive when things that cannot be done on the ground are moved into space. Liquid surface tension test makes water become a water film in space; After water injection is continued, water polo is formed; After bubbles are injected into the water polo, a positive image and a negative image are formed; Deepen the understanding of basic physical concepts such as mass, weight and Newton's law. There are also phenomena such as astronauts moving in zero gravity, communicating with the ground class in real time, spreading manned space knowledge and stimulating our interest in science.
Wang Yaping said: "Facing the vast universe, we are also students. I look forward to being able to perceive and explore the magical and wonderful space with the vast number of young friends and gain knowledge and happiness. " The universe is vast, magical and complex, and there are many mysteries worth exploring.
The grand plan of going to the moon for nine days in the past is no longer a dream. Chinese astronauts will turn the myth of the sky into reality. Indeed, in the vast space, more and more China space figures are composing the romantic feelings of the Chinese nation for the vast starry sky into realistic poems to explore space. It is reported that astronauts of Shenzhou XIII will stay in space for six months, and Chinese astronauts will spend the Spring Festival in space for the first time. Looking forward to the New Year's Eve, we can hear the blessings of astronauts from space for the first time.
I believe that in the future, we will create more space miracles and realize a newer and bigger "space dream". We will eventually write a wonderful stroke in the starry sky and leave a more wonderful China mark in the vast universe.
