孩子：Mom, do you know what happened at school today? We were doing a science experiment and it unexpectedly exploded!
妈妈：Really? Are you okay? Will the teacher be angry?
孩子：I’m okay, just a little scared. The teacher was also surprised at that time, but then they re-did it with us, and the experiment was successful in the end!
妈妈：It seems that your teacher is patient and has a good recovery ability. What did you learn?
孩子：We learned how to control the temperature and intensity of the flame. It was really interesting!
