<![CDATA[Developing students' scientific literacy requires learning resources that are interactive, contextual, and relevant to their cultural environment. This study aimed to develop and evaluate a local-content-based interactive science e-book on the topic of matter and its changes for elementary school students. This study employed a Research and Development approach involving expert validation and classroom implementation at MIN 4 Banda Aceh. The developed e-book was evaluated by material and media experts, followed by implementation with fourth-grade students. Data were analyzed using descriptive quantitative analysis to determine the feasibility of the e-book and students' scientific literacy across five dimensions. The e-book obtained highly appropriate ratings from media experts (90%) and material experts (91%), indicating that it met the feasibility criteria for classroom use. During classroom implementation, students achieved an overall scientific literacy score of 78.9% (high category). The highest achievement was observed in scientific content knowledge (89.4%) and scientific attitude (81.9%), while comparatively lower scores in scientific process, reasoning, and application in real-world contexts indicate areas requiring further instructional support. The findings suggest that the developed interactive science e-book is a feasible learning resource that supports contextual science learning and the development of students' scientific literacy through the integration of Acehnese local content.]]>
