The ability to research the natural world is a core competency of the group of natural science competencies that need to be formed and developed in learners. With regard to students in high school, the ability to research the natural world from a chemical perspective belongs to the specific competence of chemistry subject, which plays an important role in exploring, researching chemistry and discovering the world around, natural phenomena in reality, practical in daily life. From the background of the chemical science knowledge of sulfur and sulfur dioxide content in the high school curriculum, students have the opportunity to observe and relate in nature, pose problems and hypotheses that need to be investigated, explored and discovered through analysis, conduct experiments, collect data, process information, etc in order to research the nature of science and explain problems in nature. In this article, We intend to investigate the reality of our ability to research the natural world, organize teaching activities in the direction of exploring and discovering the natural world, linking knowledge learned from chemistry with natural world knowledge in order to develop the ability to research the natural world, contributing to innovating teaching methods.
