This study intends to describe the attitudes, interests, and learning outcomes of students' science and also to find out the influence of students' attitudes and learning interests on student learning outcomes. The research method was in the form of mixed methods with explanatory design. By doing a comparison test or t test, the results show that there are differences in student interest in learning in the two classes; there are differences in student attitudes in the two classes; and student learning outcomes indicate that there are differences in learning outcomes in the two classes. The results of the regression test of student interest in learning, student attitudes, and student learning outcomes in science subjects in grades VIIA and VIIB have an effect on student interest in learning, student attitudes, and student learning outcomes. The novelty of this research lies in the variables used in this study, namely three variables that were studied directly consisting of students' interests, attitudes and science learning outcomes. The implications of this research function as a reference for teachers and students in improving students' science learning outcomes.
