From Tiangong-1 to the China Space Station, the development of China's manned space project has always been closely connected with science education. "Tiangong Class" has become an important way to spread space knowledge to students in China.

On December 9, 2021, the first lesson of" Tiangong Class" began. Astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu of the Shenzhou Ⅷ flight crew showed how they lived and worked inside the space station. In a buoyancy(浮力)experiment, Wang put a table tennis ball into a glass of water. Instead of floating(漂浮)to the surface like on Earth, the ball remained in the middle of the water. Buoyancy almost disappeared in the microgravity(微重力) environment. |
On March 23, 2022, the astronauts of the Shenzhou Ⅷ brought us the second lesson of" Tiangong Class". In an experiment, WangYaping and Ye Guanglu threw Bing Dwen Dwen to each other. Bing Dwen Dwen did not land as quickly as on Earth, but moved along the same direction in a nearly straight line. In the microgravity environment of the space station, the action of objects is hardly influenced by gravity. |

On October 12, 2022, the third lesson of" Tiangong Class" was given in the China Space Station. Astronauts Chen Dong, Liu Yang and Cai Xuzhe from the Shenzhou XV flight crew brought a wonderful space science lesson to the young people.. This time, a new space classroom was" unlocked"—Wentian Lab Module. On the ground, we all use a short straw(吸管) to drink. If the straw is too long, it will be very difficult to use. But in" Tiangong Class", LiuYang successfully drank juice with a 2-meter long straw. |
