Comments on Tiangong Classroom 13

# Experience # Introduction 65438+February 9 15: 40, the first lesson of Tiangong Classroom officially began. After eight years, Chinese astronauts once again taught in space. The following is.

1. Review of Tiangong Class

I watched the program "Tiangong Classroom" today, which made me know a lot of knowledge. In 20 13, China astronaut Wang Yaping really gave his first lecture in the sky, but eight years later, today's technology is very different from the past. Moreover, the quantity and quality of cameras have improved this time, which has also caused great pressure on astronauts. And she will hold the camera in her hand, which is no easier than holding it on land.

Teacher Zhang asked us a few questions. In the space station, the cube is sown on six sides. What are the directions of roots and buds? The answer is that the roots spread into the soil and the buds grow back to the planting surface, facing the sun. Because of the gravity of the earth, the roots of plants on the earth grow underground, but in the microgravity environment of space, their roots will grow everywhere, and their roots will bend and grow in the soil.

The second question is, what will happen if the water in the teapot is poured into the cup? The answer is that the water is in the teapot and can't be poured out. In light environment, water will float on it, so it is impossible to pour water.

The third question, can goldfish swim in the open fish tank of the space station? No, because water and fish are separated, and the water will swim for a while in a short time and then separate.

On the mechanical arm outside the cabin, the astronaut holds a small steel ball in one hand and a feather in the other, and throws it in the same direction with the same force in both hands. The predetermined distance is two meters. Who will arrive first? The answer is feathers. In vacuum microgravity, the mass is small, the acceleration is large, and the feathers arrive first.

After that, I learned some wonderful moments of space flight. After that, I visited the "space home" of some astronauts and learned about some equipment in space.

I also learned that on the ground, table tennis floats on the water, while in space, table tennis is immersed in water. On the space station, buoyancy almost disappeared. A water film, after adding water to the water film, put an artificial flower in the water film, and the flower becomes bigger in the air, just like blooming. After continuing to inject water into the water film, the water film will become a water ball. Inject a bubble into the water polo, and a positive image and a negative image are formed in the water polo. Inject the pigment into the water polo, then put the effervescent tablets into the water polo. After that, there will be many bubbles in the water polo, and the water polo looks more beautiful.

After this experiment, I learned a lot from this sky lecture, and I like this sky lecture very much.

2. The feedback from the Tiangong classroom

On February 9, 65438, today, China practiced the Tiangong religion that even Americans did not practice. It is really an amazing attempt! Shenzhou 13 astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu showed a series of space scenes to people all over the world, which once again made China people further in the space field and greatly enhanced China's international strength! The astronauts became teachers and told us about life in the space station. Due to the weightlessness of astronauts in space, things that seem very simple to us, such as walking and turning around, have become a big problem in space. However, astronauts can ensure their health from all kinds of instruments, which once again demonstrates the strength of contemporary China, and the language of space experiments is different on earth. For example, water in space loses its buoyancy and becomes something like a liquid. When the astronauts put the instrument into the water, the water immediately formed a water film. Adding air to the inside will also become a double lens, one positive and one negative. When effervescent tablets are put into water. The generated bubbles will expand in the water film, but will not leak out. These experiments are really interesting. They not only popularized space knowledge, but also showed the world the power of China.

Looking at this moment, I feel deeply. It is believed that China is only a "fat meat" in the eyes of the invaders, and there is a crisis of national subjugation and extinction at any time. However, the people of China are determined to move on. In order to realize the great rejuvenation of the Chinese nation, the people of China have regained their national dignity in one war after another, and achieved a leap of standing up completely! Only by creating a glorious nation can we understand the significance of rejuvenation. Today, China has become the largest country in the world, changed its international status, and stood proudly among the nations of the world!

The future motherland needs us, and we need to work harder.

3. The feedback from the Tiangong classroom

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 bubbles divide the water polo into two parts, so that they 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".

4. Feedback from the Tiangong classroom

This "Tiangong Classroom" is mainly for teenagers and adopts the interactive mode of heaven and earth. Wang Yaping, the astronaut of Shenzhou XIII, is the main teacher, and Ye Guangfu and Zhai Zhigang are the 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.

Flowers in full bloom in the water, like the prosperity of the motherland, are blooming with their own brilliance, warmth and beauty. 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!

5. Feedback from the Tiangong classroom

A vivid "space class" is enough for the "teenagers who love the sky" in No.1 Middle School to establish the spiritual coordinates of "looking up at the starry sky" and clarify the conclusion of "down-to-earth" methods, so that they can make a positive change from "knowledge" to "action". When "the sea of stars" becomes a popular hot word, we should know more about its struggle and the lofty aspirations inspired by it. In the "Tiangong Classroom", let's cherish the romantic secrets of the universe, cherish the hard-won achievements and dream of the future.

6. feedback from the tiangong classroom

Today, the teacher organized us to watch the Tiangong Classroom. I feel that the aerospace technology of the motherland is getting stronger and stronger, and I am really proud of the motherland. Now the astronauts on the Shenzhou 13 spacecraft have to work and live in the sky for six months, which is simply amazing! Moreover, there are many high technologies on the spacecraft, such as a space treadmill, a refrigerator that can store food in space, an electron microscope ... and a magical water dispenser that can give astronauts "draft" after squeezing out water. Everyone thinks that everything in space is weightless, but this is not the case. Table tennis will not lose weight when put into water. I think space is wonderful!

7. feedback from the tiangong classroom

Living in space is really not easy. First of all, you should carry out hard training, and you should live and work in a weightless environment with unbalanced blood. This requires not only regular exercise, but also a strong will to complete various experimental tasks of the space station. Great spirit and great action, let us plug in the wings of dreams and swim in the ocean of knowledge!

8. feedback from the tiangong classroom

What are the items in "Space Home"? How do astronauts live on the space station Before the "Tiangong Classroom" started broadcasting, many small question marks popped up in my heart. I learned a lot of scientific knowledge after watching the astronauts' demonstrations and various interesting experiments. For the first time, I deeply felt that science is really everywhere. Modern technology has quietly changed the world and made our life happier. I also want to learn and explore from primary school science and love science.

9. feedback from the tiangong classroom

Today, all the teachers and students in our school watched the "Tiangong Classroom" with excitement and gained a lot. This is the second aerial class after the Shenzhou-10 space lecture. While learning knowledge, I feel the power of science and technology. From the launch of China's first artificial earth satellite, Dongfanghong-1, to the implementation of the Shenzhou-13 mission, it is a good symbol of the country's scientific and technological development. Today, China has become a leader in scientific and technological innovation and is developing rapidly. I am extremely proud of the great achievements made by my motherland.

10. Review of Tiangong Class

Teacher Wang Yaping once said, "Dreams are like stars in the universe. They seem out of reach, but if you work hard, you will definitely be able to touch them." She is the first female astronaut in China to enter the space station. She saw the report that Yang Liwei went into space that year, which inspired her dream of exploring space. After that, she sweated profusely and ran towards the goal with all her strength. In the "devil" training day after day, she approached her dream step by step and went to space twice, becoming a dazzling star in China's space flight. Wang Yaping, a "space teacher", ignited my dream with her own experience. Now, I will follow the example of astronauts, make down-to-earth efforts, constantly stimulate my potential and vitality, and contribute to the Chinese dream of realizing the great rejuvenation of the Chinese nation.

1 1. Comments on Tiangong Classroom

Today, I watched a special "space science class" with the children. The students' surprise at the space experiment made me think. Although the experiment in science class can't be as magical as the space experiment, we should design diversified and intuitive inquiry activities to stimulate students' interest in scientific research. At the same time, as a science and technology counselor, I also realize that it is my responsibility to cultivate young people with scientific and technological innovation and contribute to the Chinese dream of realizing the great rejuvenation of the Chinese nation.

12. Comments on Tiangong Classroom

Gyroscope floats and rotates in the air, myocardial cells keep beating, and blue water polo bubbles ... Today, China Space Station teaches in space for the first time, bringing wonderful Tiangong courses to our audience on earth, and magical scientific experiments show various phenomena different from the earth in space. Intuitive, vivid and enlightening teaching attracted bursts of amazement and applause, which ignited students' enthusiasm for exploring scientific mysteries. While the students opened their eyes, they also realized the great efforts made by the astronauts, teachers and researchers behind them in the process of space exploration. In the future science class, I will guide students to keep learning and exploring, go forward bravely and create a more brilliant future!

13. Comments on Tiangong Classroom

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!
