初中物理教材,密度测量占有比较重的份量,本内容往往定位在应用与综合应用上;在近几年的中考物理试题中,密度的测量设计题频频出现·因此教师应该高度重视密度的设计与教学,从学生平时解答与考试效果来看,学生在这一问题上得分率很低,究其原因,有以下几点:首先密度测量设计题综 In junior high school physics textbooks, density measurement occupies a heavier weight, and this content is often positioned in applications and comprehensive applications; in recent years, in middle school physics test questions, density measurement design questions have appeared frequently. Therefore, teachers should attach great importance to the design of density and Teaching, from the student’s daily answer and test results, the student’s score rate on this issue is very low, the reason for the following points: First, density measurement design problem
