Recently, a number of in-service seminars for teachers have been held to re-educate teachers. It is important to develop an experimental program for teacher education in which the program is consistent with a curriculum and applicable in a wide range of institutions from elemental to high school. We developed a package program with a series of experiments related to table salt. The program includes four chemical concepts; a solution, structure of atom and ion, state of matter, and weight and volume. The program was tried at a workshop for elementary school teachers and evaluated by a questionnaire. The trial program and the results of the survey indicated that the program is appropriate for teacher education.
