Abstract By changing the observation method to visualize the experimental process and phenomena. Macro photography function was achieved by clamping macro lens on the rear camera of mobile phone, the reaction of sodium silicate solution and mung bean big metal salt in a test tube was captured by video, the video editing software "master" was used to set play times, and multimedia teaching showed the experiment phenomena. Results show that this method can capture the reaction process, get clear and enlarged pictures, and the experimental phenomena details are obvious.
