This definition of law, for teachers should be easy to understand, but also very reasonable. But for junior high school students, “Other Matter ” is a word that is difficult to understand. Because from small to large education, are telling children: different names, are different substances. This gives students to judge “physical changes ” “chemical changes ” caused great difficulties. Especially for junior high school students who have just come into contact with the discipline of chemistry, in the face of this
