Learning outcomes are an important aspect in education, because student learning outcomes are used as a starting point for learning activities during students at school. This study was motivated by the low or lack of science learning outcomes of grade IV students of SDN Kembangan Selatan 03 on the material of forces around us. The purpose of this study was to improve students' science learning outcomes on the material of forces around us by using one of the approaches in learning, namely the Scientific Approach. The data analysis technique used was Classroom Action Research which in each cycle includes design, implementation, observation and reflection activities. The results of this study indicate that the application of learning strategies using a scientific approach can improve students' science learning outcomes, as evidenced by the increase in the completion of learning outcomes in each cycle, the completion of students' learning outcomes in cycle 1 meeting II was 83.8% with the number of students' completion whose scores were above the KKTP as many as 26 students. Meanwhile, the completion of the science learning outcomes of students in cycle 2 meeting II was 93.5% with the number of students whose scores were above the KKTP as many as 29 students. After the calculation in cycle I, the results of the science learning of students in meeting 2 were 72% and the average results of teacher activity observations in cycle 1 meeting II were 80%. Meanwhile, the average for cycle 2 meeting 2 was 91% and the average results of teacher activity observations in cycle 2 meeting 2 were 92%, where there was an increase in each cycle. Thus, the increase in the learning process can be seen from the enthusiasm of students to learn which became active after the teacher introduced the scientific approach.
