Abstract: This research presents the development and validation of a Supplemental Instructional Material (SIM) in Science for Grade 6, specifically focused on the Biology component of the curriculum. Prompted by the pressing need for contextually relevant and pedagogically sound instructional resources, especially in light of challenges experienced during the COVID-19 pandemic, the study employed a descriptive-developmental design. The SIM was evaluated by science education experts and top-performing students from elementary schools within the Borongan City Division, using established validation criteria such as usability, consistency, clarity of objectives, content quality, curriculum alignment, presentation, and evaluative effectiveness. Quantitative analysis utilizing weighted mean and paired t-tests revealed high levels of validity across all dimensions assessed. The results affirm the material's potential as a quality-assured learning tool that enhances concept retention and engagement in science learning. This study underscores the importance of localized, research-based instructional materials in improving science education outcomes.
