Abstract: This study investigated the effectiveness of Small-Scale Chemistry (SSC) in enhancing the learning outcomes of junior high school students, focusing on their conceptual understanding of chemical reactions. Utilizing the ADDIE model (Analysis, Design, Development, Implementation, Evaluation), the research addressed critical gaps identified through a needs assessment involving 150 participants, which revealed significant deficiencies in abstract topics like biomolecules and the mole concept (82% scored below passing, mean = 13.86). The implementation on needs assessment with 96 learners further confirmed SSC’s impact, as evidenced by a 22% increase in high achievers and reduced low-scoring students (38% to 22%). A pilot test with 45 learners demonstrated the efficacy of Small-Scale Chemistry interventions, with post-test results showing a statistically significant improvement in conceptual scores (mean increase: 10.64 to 15.93, p
