The purpose of the study was to classify scientific models in the seventh grade science textbooks of the 2007 revised science curriculum. The three chapters of ‘three states of material’, ‘motion of molecule’, and ‘change of state and energy’ were investigated. There were two types of the scientific model as ‘mode of representation’ and ‘attribute of representation’. The mode of representation was composed of ‘action model’, ‘analogical model', 'symbolic model’, and ‘theoretical model’ and the attribute of representation was composed of ‘static model’ and ‘dynamic model’. The results showed that the action model and the analogical model were used primarily in mode of representation. The dynamic model were widely used in attribute of representation. Area of matters dealt with conception of molecules and aimed for students to understand the arrangement and movement of molecule microscopically about macroscopic state in a daily life. Tis study could help to recognize the limitations of scientific models on current textbooks and offer more useful information in planning lessons and organizing textbooks for the future.
