Abstract Based on the abstract knowledge teaching of atoms and molecules in high school chemistry, this paper discussed the application of modern analytical instruments in high school chemistry teaching by taking the experiments of sunscreen protection effect as an example. By using the modern analysis instrument UV-Vis spectrophotometer to explore the sunscreen protection effect, analyzed and mastered the chemical sunscreen mechanism combining with the ultraviolet discolor-changing ball experiments. The results showed that the greater the thickness of the sunscreen and the higher the SPF, the better the protection effect of the sunscreen, the sunscreen could last for a period of time, but there were some differences between different types of sunscreen products. The applications of modern analytical instruments in chemistry teaching would lay a solid foundation for students to further understand the chemistry discipline in changing the learning way, broadening the field of subject knowledge, and promoting their comprehensive and sustainable development.
