According to the China Manned Space Engineering Office, the second lesson of the "Tiangong Classroom" will be held tomorrow (March 23) at 15:40 on the China Space Station, and the astronauts of Shenzhou 13, Zhai Zhigang, Wang Yaping, and Ye Guangfu, will cooperate with each other to teach. This is also the third time that Chinese astronauts have taught space.
What is this lesson about? Take a look at the curriculum: At that time, astronauts will demonstrate space "ice and snow" experiments, liquid bridge demonstration experiments, water and oil separation experiments, space parabolic experiments, introduce and display space science facilities, and there is also a space-earth interaction link, astronauts sincerely invite all sectors of society, especially the majority of young people, to try to carry out relevant experiments on the ground. In this lecture activity, CCTV will broadcast live to the world.
The Star Sea Boy said
For the upcoming second lesson of the "Tiangong Classroom", teenagers across the country are full of expectations.
What are you most interested in about the space station?
Shen Zhouren, a student at The Wuzhou Chinese School of Zhejiang Normal University: We have gravity on Earth, so food can enter the esophagus and digestive tract smoothly, but I am not quite sure what will happen to this food entering the digestive tract in space, whether it will float up or go down as smoothly as the earth, so I want to know the answer to this question.
Cai Donglin, a student at Longhu School in Huizhou City, Guangdong Province: I want to know if seeds can sprout and grow like they do on Earth without sunlight on the space station?
Deng Zhensen, a student at Zhongzhou Experimental Primary School in Huizhou City, Guangdong Province: What I am most interested in is whether there is WiFi in the space station, how is it connected to the earth, and where does the oxygen supply of the space station come from?
Yu Qiwen, a student at The Wuzhou Foreign Chinese School of Zhejiang Normal University: Resources are limited in space, so I am very curious about how to collect garbage and dispose of it again, and once again be able to generate some new resources.
Lin Qihan, a student at Zhongzhou Experimental Primary School in Huizhou City, Guangdong Province: I am most interested in the system of reusing their water, because they (systems) regenerate water, and then filter out all the impurities and bacteria in the water.
Student of Shanglin Junior High School in Cixi City, Zhejiang Province Ying Kamzhi: As a stargazing enthusiast, if you observe the starry sky on the space station, will there be any convenience? Will this be of any benefit to our scientific experiments?
If you could get into the space station, what would you most like to do?
Fang Ruo, a student at Wuzhou Wai Chinese School of Zhejiang Normal University: What I most want to do is to look at the stars of the universe through the porthole of this space station, because we are affected by various environmental factors on the earth, and we often don't see very really, so I think in the space station, it will be very beautiful.
Xiao Xiang, a student at Deai School in Jiangdong New District, Heyuan, Guangdong: I just wanted to drink water on the space station, because the water floats up on the space station, granular, and very interesting. I wanted to put this stuff in my own mouth and experience the feeling.
Deng Zhensen, a student at Zhongzhou Experimental Primary School in Huizhou City, Guangdong Province: If I have the opportunity to enter the space station, I would like to light a match on the space station to see how the flame on the match is different from that on Earth.
Zhang Nuosi, a student at Deai School in Jiangdong New District, Heyuan, Guangdong: What I want is to take a pot of plant up to observe its growth direction, to see what is different from the (growth) direction of this plant on the earth, in that kind of space environment, whether it can grow exactly the same as on earth.
Zheng Yutong, a student at Sichuan Zigong Bancang Experimental School: I would like to be able to lift weights on the space station, and I wonder if if there is no gravity barbell that will be lifted because there is no gravity.
Zhu Yuxuan, a student at the Wuzhou Foreign Chinese School of Zhejiang Normal University: I most want to observe the direction of the compass in space and the deflection of the compass in space.
What experiment would you most like to do on the space station?
Yu Xinying, a student at the Baohu Campus of Tanglai Muslim Middle School in Yinchuan City, Ningxia: I hope to put a piece of feather and an iron ball at the same height and fall at the same time to see if they will fall to the ground at the same time.
Fang Ruo, a student at The Wuzhou Chinese School of Zhejiang Normal University: The experiment I most want to do is the cultivation of rice, because on earth, the growth of this rice is affected by the alternation of seasons, so I wonder if there will be some new varieties on the space station without the alternation of seasons?
Students of Shanglin Junior High School in Cixi City, Zhejiang Province: If I can grow food every month through space station experiments, then human beings around the world will not have to worry about food problems.
Chen Junxi, a student of Shanglin Junior High School in Cixi City, Zhejiang Province: I want to do the radiation of outer space, the impact on human brain power, we all know that now human brain power has not been fully developed, so is it possible that after the influence of outer space radiation, human brain power can be developed to a new height?
Li Boxian, a student at Jiaojiang No. 5 Middle School in Taizhou, Zhejiang: What is the difference between the growth and development of the human body in a weightless environment compared to the growth and development under normal gravity? Is it inhibitory or promoting? I want to do experiments like this.
