fetched some solution(溶液 ) from the cupboard, including oil of vitriol(濃硫酸 ), and put them on the table. Wang Hua and Ding Ding were in the front row. Xiao Ming and I were in the second row.

Soon a hole was burned in Xiao Ming’ s coat. And his hand was burned to black. He screamed. We were so worried. The teacher ran over to send Xiao Ming to the nearest hospital. Fortunately, nobody else was injured in the incident. However, it taught us a good lesson. Never leave a bottle uncovered on the table. S2: I’ d like to tell you about one of the incidents in our chemical experiment. In the experiment, we used Bunsen burner. After the experiment, one of my classmates fot to cover it. About ten minutes later, a teacher passed the laboratory and smelt the odd smelling. She immediately entered the lab and put out the fire. Fortunately, no further incident was caused. After that all the teachers and students were gathered to have a meeting. The headmaster gave a talk to emphasize the importance of safety in lab. That’ s a good lesson. T: Yeah, if the teacher didn’ t notice the incident, it would have been a terrible fire. We often think it’ s impossible to make an accident. But as a saying goes, “ It’ s not too careful to do a thing.” We should always keep the saying in mind. Step Ⅴ Cultural Corner T: In this Module, we’ ve learned many things about scientific experiment. Maybe some of you find it interesting, because you are interested in science。整體來說,這是一節(jié)成功的課,因?yàn)槲易龅搅艘詫W(xué)生為主體并創(chuàng)造了讓每個(gè)學(xué)生都有機(jī)會(huì)證明自己“我行”的教
