This research aims to improve student learning outcomes through the application of the class VI Inkuri learning model at SD Negeri 064974 Medan Tembung for the 2024/2025 academic year. The subjects in the research were 20 class VI students. The techniques used by researchers in collecting data are observation and tests. The learning model used in this research is the Inquiry learning model. This research shows an increase in student learning outcomes in the science and science subject DEVELOPMENT OF LIVING CREATURES in class VI of SD Negeri 064974 Medan Tembung for the 2024/2025 academic year. This is evident from the results of research conducted on the pretest (initial test) which received a complete score of 6 students or 25%, while those who received an incomplete score were 15 students or 75%, with an average learning result of 56.7.
