In this study, visually impaired secondary students’ conception of “changes of state of water” was explored. Science inquiry activity for students with visual impairments was implemented to 16 middle school students and 15 high school students from school for the blind. 14 of them were totally blind, 13 had low vision and the others were not identified. Inquiry activities were conducted by communicating with the researcher while students were individually exploring the molecular models of water and ice developed for the study. After the exploration, students were asked to explain the concept of changes of state of water with the model they explored. Opinion on the need and the usability of this kind of tactile model was also asked to them. All conversations were recorded, transcribed, and analyzed. As a result, students with visual impairments answered exactly about the materials used for the model and their numbers. However, they didn’t know what the model stood for. They had experiences of learning molecule of water and changes of state of water, but it was a phenomenon and superficial understanding. Students got to understand the molecular structures of water and ice, and had a positive perception on the need and the usability of the model. Based on these results, educational implications were discussed.
