Science practice is a process of establishing new relationships with 'foreign things' such as learning objects or tools for observation and measurement. Since the practice of science in major subjects has been increasingly emphasized, we sought to understand the meaning co-created by students and numerous materials who have experienced astronomical observation as a Deleuzian experience of "becoming". We collected activity logs and photographic data written by 17 students participating in astronomical observation activities at "A" High School, and conducted in-depth interviews with the students. We assessed the collected data by reconstructing a situation analysis. The main research results include the students' existential-epistemological 'becoming' process: 1) discovering newness through repetition, 2) becoming an 'explanation machine' to convey the affect of astronomical observation activities, 3) breaking out of a stabilized territory, and crossing a threshold. Based on the results, we suggested the need for follow-up research on the practices and new experimental approaches of teachers in earth science education.
