"When the water ball calmed down, Teacher Liu Yang threw a hollow iron ball into the water ball, and then used the same force to shoot air at the water ball. The water ball actually seemed to have become 'lazy' and remained motionless. It was so amazing!"

"When the water ball was calm, Liu Yang teacher threw a hollow iron ball into the water ball, and then used the same force to shoot air at the water ball. The water ball actually seemed to have become 'lazy' and remained motionless. It was amazing!" Yin Yixiao, a student of of Kaifeng Second Normal School Affiliated Primary School, watched " Tiangong Classroom ", recorded his feelings in words.

htmlOn the afternoon of October 12, the third lesson of "Tiangong Classroom" was taught in China Space Station . "Space Teacher" Chen Dong , Liu Yang, Cai Xuzhe brought a wonderful space science popularization class to young people. This is the first time that Chinese astronauts in taught in the Wentian Experimental Cabin.

"I learned that the 'Tiangong Classroom' was about to start, our school prepared early and organized all students to watch this special 'experimental class' together." A teacher from Kaifeng Second Normal University Affiliated Primary School told reporters.

During the course of about 50 minutes, astronauts of Shenzhou 14 flight crew, Chen Dong, Liu Yang and Cai Xuzhe, vividly introduced and displayed the working and life scenes of the space station question-and-day experimental cabin, demonstrated the capillary effect experiment in the microgravity environment, the experiment of "lazy" water balloon, interesting drinking water in space, and the wrench that can turn heads, and vividly explained the scientific principles behind the experiment. In addition, the astronauts also focused on the research on rice and Arabidopsis thaliana planting carried out on the Chinese space station, and demonstrated the operation of glove box plant shearing. During the lecture, the astronauts interacted with teachers and students in the ground classroom through video calls, and the ground classroom experts also carefully analyzed relevant scientific issues.

Yin Yixiao wrote in his review of "Tiangong Classroom" that through the online classroom, they "walking into" the Wentian Experimental Cabin and visited the sleeping area, small kitchen, and various experimental cabinets of the experimental cabin. "Today is really an eye-opening day. The experimental cabin is so rich." From the excitement words, it is not difficult to see the excitement of primary school student Yin Yixiao.

Lu Jingxian, who is also from Kaifeng Second Normal University Affiliated Primary School, wrote in his review of "Tiangong Classroom": "After the experiment, Uncle Chen Dong showed us the 'Xiao Nan' and 'Rice' in space. A huge droplet of water actually 'spited' from the leaves of the rice, which is really interesting!"

"Teacher Chen Dong put a few tubes into the water. A magical thing happened: the water actually walked up the tube! I have never seen this phenomenon before." Zhang Jiawei, an elementary school affiliated to Kaifeng Second Normal University, also expressed his excitement through the form of a short composition.

It is understood that during the construction and operation of the space station, "Tiangong Classroom" will continue to carry out space teaching activities to carry out aerospace science popularization education in various forms and rich content.
