Abstract In the movie and scientific research of Mars, water is a hot research topic. The latest literature in Science reported that liquid water exists beneath the Antarctic ice cap on Mars. Combining the phase diagram of pure water in Physical Chemistry, the difference between water triple-point and freezing point, the Clapeyron equation, freezing-point depression and other knowledge points, we can understand the contents of the research report well. The combination mode of research hotspots and teaching knowledge points is beneficial to cultivate students' interest and the comprehensive scientific thinking ability of high school students.
