STEAM education method helps students connect learned knowledge with practice. This article aims to design a STEAM-based lesson titled Specialized vinegar fermentation barrel within the theme of "Substances and their transformations" focusing on enhancing the representative competency of students in Grade 8 Natural Sciences. The study involved conducting a survey and implementing pedagogical experiments based on a cross-sectional survey method and a pre-and-post-intervention experimental design with randomized groups. After the intervention, the proportion of students achieving the highest competency level (Level 3) increased significantly, from below 20% to 40-50%, and the average representative competency score improved from 6.06 to 7.44 on a 10-point scale. The results of the pedagogical experiment demonstrated positive development in learners’ competencies and highlighted the feasibility and necessity of integrating STEAM themes to foster representative competency.
