The three taikonauts (航天员) Zhai Zhigang, Wang Yaping and Ye Guangfu give a science lesson from China’s space station, Tiangong. The lesson is so different.
The class is about 45 minutes. 1,420 students have the class. It’s Wang’s first time having a space station tour. She shows the students how they live and work there. They can also do sports. In their kitchen, she takes out a fresh apple from a mini-fridge. After the tour, the three taikonauts do some fun tests.
They are so interesting. At the end of the class, the students make a video call in real time, and the taikonauts answer their questions.
The students like the special class and may fall in love with science. That’s cool!
