Especially when teaching abstract and microscopic physical phenomena such as heat conduction, the influence of different materials on heat transfer efficiency, the traditional teaching method, that is, simply relying on teachers' oral explanation and book description, often makes it difficult for students to establish intuitive and deep understanding. Under this teaching mode, students often can only passively accept knowledge, lack of active exploration and practice opportunities, thereby affecting learning interest and learning effect. In order to overcome this teaching problem, the application of teaching aids in physics teaching is particularly important.
