A teacher walked into a classroom. 【小题1】 As he pointed the wand (手杖) at a hanging light in the classroom, an electric arc (电弧) appeared from the top of the wan d and lit up the light. This wowed (博得……称赞) the whole class.

【小题2】 No. It was a physics class. The teacher is Xia Zhendong, a 31-year-old physics teacher. He works at a middle school in Jingdezhen, Jiangxi Province. Xia has won the hearts of millions of people online with his creative classroom experiments (实验) that make physics easy to understand and interesting.

Xia’s journey to bringing creative experiments into his teaching began six years ago. His idea came from a wish to interest his first students in 2017, who had difficulty learning physics. 【小题3】 Since then, Xia has started bringing experiments into his physics classes. “A year later, I noticed a great improvement in their grades,” he shared.

Over the years, Xia has done over 200 experiments in his classes, nearly one experiment a week. At first, he put up his videos online just for sharing. In February 2021, one of his videos unexpectedly became popular, bringing him over 10,000 followers. 【小题4】 As a result, this ordinary (普通的) teacher found himself becoming an Internet star with over a million fans.

Now, Xia is trying to do more than sharing videos. He wants to help with science communication by offering meaningful and valuable lessons. “【小题5】 I will keep going,” he says.
