摘　　要：介绍了一种利用霍夫曼水电解器装置直接称量电解水前后反应体系的质量来验证“质量守恒定律”的创新实验方法。宏微观建立质量直观联系,初探质量守恒定律的宏观视角。相对于教材传统实验方法,新实验方法具有以下优点:前后单元知识融合度更高,知识链延续性更强,课堂更高效、节约药品、节省实验时间,提高了教学有效性和趣味性。This article introduces an innovative experimental method for verifying the“law of mass conservation”by directly weighing the mass of the reaction system before and after electrolysis of water using a Hoffman water electrolyzer device.A visual relationship between mass from macro and micro perspectives,and explore the macro perspective of the law of mass conservation were established.Compared with traditional experimental methods in textbooks,this method has the following advantages:higher integration of knowledge between the front and back units,stronger continuity of the knowledge chain,more efficient classroom,saving drugs,and experimental time,improving the effectiveness and interest of teaching.

关 键 词：课题融合 质量守恒定律 创新实验
