Chemical experiment is a window for students to know the objective world and an important means to learn chemistry.
The formation and development of chemistry stems from and depends on experiments.
Chemical experiment helps students to understand and consolidate knowledge, cultivate their practical ability and master scientific learning methods.
If a lot of chemistry knowledge is not based on experiments and is not taught by experimental means, it will be difficult for students to leave a deep impression on what they have learned, and they will feel that chemistry courses are abstract and boring, which will gradually make students lose their interest and motivation in learning chemistry.
