Under the background of the new curriculum reform, the education of physical science methods is of great significance in cultivating students' core literacy. However, whether it is in the presentation of textbooks or in teaching activities, scientific methods often exist in an implicit way. This article takes the Cavendish torsion scale experiment, one of the "Top Ten Most Beautiful Experiments", as an example for teaching innovation. Through a review of the history of physics, the application of scientific methods is guided by the problem driven approach of "substituting questions, setting questions, exploring questions, and explaining questions" to guide students to explore the scientific methods in the experiment, develop their scientific thinking and exploration literacy, and provide new ideas for the visualization teaching of scientific methods in physics experiments.
