In order to respond to 2022-2023 IYBSSD basic science to promote sustainable development of the international year, the Qing University Cross-domain Science and Education Center cooperated with Xiaoming Women's Middle School to jointly organize Tsinghua FUN scientific inquiry courses. Nitrogen -related scientific knowledge also hopes to trigger female students' interest in science through actual practical experience, with a view to being a shining star in the scientific field in the future.nAt the beginning of the course, Professor Dai shared the memories and experiences of his past studying women's schools with the students, closer the distance with the trainees, and then brought this course theme-liquid nitrogen. The liquid nitrogen experience is a very novel and interesting course for students, and it is also accompanied by danger. Therefore, Professor Dai and teaching assistants will explain the precautions of liquid nitrogen activities and their possible dangers before the course. After the trainees can understand it, I started today's experience activities. The trainees all felt very interesting, and the laughter and laughter continued.n
