A multi-solution can inspire and guide students from different perspectives and different ideas to analyze and answer the same exercises. It can fully mobilize the enthusiasm of students’ thinking, improve students’ skills and abilities to use the learned knowledge to answer physics problems, exercise the flexibility of students’ thinking, broaden the students’ thinking, and guide students to have a flexible grasp of the vertical and horizontal links between the knowledge and develop and develop students’ knowledge. Creativity, development of intelligence, and ability to solve problems. The following is a description of exercises in a textbook. Title: (Shanghai Science Edition 2nd P115) When measuring the liquid density, one classmate measured the volume of the liquid, the total mass of the container and the liquid, and the experiment was done twice. The record is as follows:
