Learning Natural and Social Sciences (IPAS) in elementary schools requires a concrete and contextual understanding of concepts. However, classroom learning practices are often dominated by textbooks and lecture methods, resulting in students being less actively involved in the learning process. This community service activity aims to implement cardboard media as an alternative learning medium for ecosystem material in grade III of SDN Cibening 03, Bogor Regency. The implementation method includes the preparation stage, group-based learning implementation, and observation and reflection on student and teacher responses. The results of the activity show that the use of cardboard media can increase active student engagement, foster enthusiasm for learning, and help students understand the concepts of biotic and abiotic components more easily. Teachers also gave a positive response to the use of this media because it is considered practical and effective. This activity shows that concrete learning media can be a simple solution to improve the quality of IPAS learning in elementary schools.
