5、2013年6月20日在中国各地，剧估计60万儿童和他们的老师观看了有宇航员(astronaut)王亚平在距离地球300公里的上空所讲授的科学课。王亚平与两个同事乘坐天宫一号实验舱(the Tiangon-1 laboratory module) 执行为期两周的任务。她在课上进行了一系列太空的物理演示。在有些演示中还对比了在地球上重力(one-gravity)环境下同样的实验。这堂物理课不仅让孩子们享受了一堂知识与乐趣兼具的物理课，也显示了我国通信科技的前进。

On June 20, 2013, an estimated 600 thousand school children and their teachers across China watched a science lesson taught from 300km above the Earth by astronaut Wang Yaping. Wang is aboard the Tiangong-1 laboratory module with two crewmates, for a two-week mission. Her lessons were a series of physics demonstrations in the space. In some demonstrations,she compared with the same experiment under the one-gravity environment on Earth. The lesson has not only offered children a physics lesson with knowledge and interest, but also shows the advance in communication technology of China.
