Wang Yaping s impression of space teaching is 500 words

At 10 a.m. on June 20, this is an exciting moment when China will conduct its first space lecture on the Shenzhou spacecraft. This is unprecedented in our country and the second time in the world. Therefore, the Shen 10 Space Teaching is not only a prosperous era for the whole country, but also a prosperous era for scholars and friends in the fields of astronomy and physics around the world.

When was the first space lecture? In fact, as early as 1985, NASA proposed the idea of teaching in space, and trained two female teachers for this purpose, one is McAuliffe and the other is Morgan. Sadly, however, McAuliffe and the spacecraft died together in the space of the spacecraft when the spacecraft lifted off the following year – 73 seconds after liftoff, the spacecraft Challenger suddenly shattered.

However, Morgan did not give up on this dream of teaching in heaven, and she prepared for this for another 22 years. Finally, in 2007, she conducted the world's first space lecture on the International Space Station, giving students a 25-minute lesson and showing how astronauts exercise in space and how to drink water in space.

Coincidentally, this time my country is also taught by female astronauts, but the difficulty of teaching is much greater than that of Morgan - this time Wang Yaping mainly shows some physical phenomena in a weightless environment, and the demonstration is no longer drinking water, exercising and other things that we have already been more clear, but physical concepts with higher scientific and technological content.

In this lecture, Wang Yaping mainly demonstrated five experiments, namely mass measurement, single pendulum motion, gyroscopic motion, water film and water balloon and other five basic physics experiments, mainly to let young people understand the characteristics of object motion under weightlessness conditions, what is the role of liquid surface tension, and at the same time deepen the understanding of basic physical concepts such as mass, weight and Newton's laws. These five experiments may not seem simple, but the physics behind them is surprising and profound!

Did they delineate this experiment themselves in advance? Not really. Some of the problems in this experiment were collected by the China Manned Space Engineering Network, and this is not only a breakthrough in aerospace, but also a breakthrough for the young people themselves.

Because only questions with demonstration value can be solicited, this requires us teenagers to supplement more relevant knowledge, so that we can enrich ourselves from the inside out, and not be strong from the outside and empty in the middle.

Some people ask if the domestic water in space is recycled. I'm also interested in this issue. Commander Nie Haisheng told us that the water in the spacecraft is brought from the earth, but it is not yet recyclable, because it requires more advanced technology and complex equipment.

Hearing this, I couldn't help but feel a little sad, how hard their life in space must be.

Perhaps, whether the recycling of domestic water in space can be realized depends on our young generation. I believe that in the near future, there will be more people who are interested in the mysterious space and are willing to exert greater strength for our aerospace industry, and move closer to the realization of our "Chinese Dream and Space Dream"!

On June 16, 2013, Tiangong-1 and Shenzhou-10 successfully achieved automatic rendezvous and docking, and three astronauts will then enter Tiangong-1 and carry out relevant space science experiments and technical experiments, and carry out space teaching activities.

In the space capsule, Wang Yaping showed us a series of small details of astronauts' lives in space, as well as some small questions about space for primary school students across the country. It gave me an understanding of the motion of objects in a microgravity environment, the action of surface tension in liquids, and a deeper understanding of basic physical concepts such as mass, weight, and Newton's laws.

Although the space lecture was only 40 minutes, I felt that I learned more in these 40 minutes than I learned in one day, and it also gave me a better understanding of space. I really wish there were more similar space teaching activities like this.
