In this study, we aimed to clarify how particle concepts are acquired and changed through a teaching method based on the building process of theory. We analyzed the concepts and processes learned by elementary school students by examining and analyzing lesson content (totaling 6 units from the third grade level “material and weight” to the fourth grade level “the destination of water”) over a period of 53 hours. As a result, the students acquired the following concepts (a to e) and the process of change in these concepts was clarified: a) Materials are composed of invisible small particles. b) Particles do not disappear. c) The size of the particles does not change. d) Particles move in all directions when heated. e) The difference in state occurs due to the difference in the size of the gap between the particles and the movement of the particles.
