Abstract
matter properties and matter changes divided into physical change and chemical change. In the science historical view-point, the general ideas of the base that represent matter properties has been variously revised the 5types. The definitionof the mater change have also changed the 3 types. From the analysis of the definitions in secondary school science text-books and general chemistry textbooks, we found that a lot of confusion of eras in the contents that define the concepts.Sometimes, the definition presented in one textbook was contradictory to the definitions in other textbooks. This ten-dency has been sustained in the textbooks from the 4th to 7th science curriculum.
