The problem in this research is whether there is an increase in students' critical thinking skills in science subjects regarding the human respiratory system using the problem based learning (PBL) learning model for class V at SD Negeri 2 Margorejo for the 2022/2023 academic year. The problem that often arises in science learning is students' low critical thinking skills which have an impact on student learning outcomes. When students do not have critical thinking skills, it is very difficult for students to solve problems or problems in science learning. The aim of this research is to determine the increase in students' critical thinking skills in science subjects regarding the human respiratory system using the Problem Based Learning (PBL) learning model for class V at SD Negeri 2 Margorejo for the 2022/2023 academic year. The method used in this research is classroom action research which was carried out over 2 cycles. Data collection techniques in this research are through observation, tests, interviews and documentation. The results of classroom action research which was carried out for 2 cycles at SDN 2 Margerejo showed an increase in students' critical thinking abilities in learning using the Problem Based Learning learning model. Based on the student worksheet scores, it is known that of the 17 students who worked on the LKS in cycle II, there were 9 students (52%) with very good information, 5 students (29%) with high information, 3 students (18%) with medium information. Meanwhile, seen from the observation data on students' critical thinking skills in cycle II, there were 9 (52%) students for very critical criteria, 5 (29%) students for critical criteria, 9 (18%) students for moderately critical criteria and no students for the less critical and uncritical categories.
