This study examined secondary school science teachers’ thinking on physical and chemical change. For this research, we analysed the answers of 80 secondary school science teachers. According to the result of the analysis,teachers had various opinions when they classified phenomena of dissolving ionic compound or diluting acid into phys-ical change and chemical change. Many teachers tended to classify similar phenomena into different change when those were represented with different focus. It means that teachers’ opinions were not consistent.
