This research aimed to investigate the students’ constructing scientific knowledge about diffusion and osmosis with analogy approach. The subjects were selected by purposive sampling method including 30 Grade 7 students in Yasothonpittayakom School, Muang District, Yasothon Province, Thailand, in second semester of 2014 academic year. Gathering data by semi-structured interviews and open-ended questionnaire. The data analyses were qualitative analytical techniques. The results of study revealed that almost students held the concept of dissolve to mention diffusion and held the concept of the particulate and the movement of particulate. Their explanations of diffusion and osmosis mentioned various phenomena.
