　　(原创)BEIJING, June 20(Xinhua)—Over 60 million students and teachers at China’s 80, 000 middle schools experienced a special class delivered by China’s first teacher in space from more than 300 kilometers above the Earth’s surface.

　　“Hello, everyone. I am Wang Yaping. I will host the lecture today. ”Female astronaut Wang Yaping, one of the three crew members of Shenzhou-Ⅹspacecraft, greeted about 330 students at a Beijing high school, through a live video feed system. The students on her class included children from migrant workers’ families, of ethnic minorities and from Hong Kong, Macao and Taiwan.

　　In this space class, Wang carried out some physics experiments about motion(运动)and surface tension(张力)of water in a micro-gravity environment(微重力环境), which can help students better understand weight, mass and Newton’s Laws. The most amazing one is“a water ball”, Wang Yaping makes a water film(水膜)with a water bag and a metal ring. She explained to students that the surface tension of water enlarges in space because of zero gravity. Then she made a second water film turn into a water ball.
