Abstract Based on STEM education, this paper introduced a simple and efficient method to prepare manganese dioxide-loading sodium alginate microcapsule, and guided students to inquire the optimum conditions for decomposition of hydrogen peroxide catalyzed by these microcapsules with handheld technology. This experiment was simple to operate, non-pollution, with obvious phenomena and less reagents, through which students not only observed the experimental process more clearly but also deepened understanding of quantitative research.
