This study aimed to develop a science module using the Problem Based Learning (PBL) model integrated with local wisdom for fourth-grade elementary school students that was valid and practical. This study employed Research and Development using a modified 4-D model consisting of define, design, and develop stages. The practicality trial involved one teacher and 23 fourth-grade students of SDN 10 Lambung Bukit. The module was validated by material, language, and design experts. Validity data were analyzed using Aiken’s V, while practicality data were analyzed using percentages. The results showed that the module obtained Aiken’s V scores of 0.80 from the material expert, 0.94 from the language expert, and 0.94 from the design expert, categorized as highly valid. The practicality scores were 90% from the teacher and 88.26% from the students, both categorized as highly practical. Therefore, the developed science module using PBL integrated with local wisdom was valid and practical as supplementary learning material for fourth-grade science learning, particularly on energy transformation.
