Abstract In view of the teaching experiment on the nature of sodium, some examples of analysis had problems such as unclear experimental videos and difficult observation of phenomena for students in the middle and back rows, and the poor visualization effect of the experiment led to students’ inability to deeply understand the properties of sodium. The observation method of macro photography and thermal imaging was used to visualize the experimental process and phenomena. The macro lens clipped on the rear camera of the mobile phone captured the reaction of sodium metal with oxygen and water, realized the macro photography function, and used the “Capcut” video editing software to set the “Playback Multiple” as needed, and added the “Beautiful Chemistry” thermal imaging video, and used teaching multimedia to present the experimental phenomenon. The results showed that the experimental phenomenon was intuitive and shocking, which could effectively help students implement the core literacy of evidence reasoning and scientific inquiry, and this method had good promotion value.
