摘　　要：增加趣味性在化学实验中的比重,能够提升教学效果,巩固和加深学生对化学知识的理解。以"五水硫酸铜晶体的制备及表征"实验为例,把观察实验结果变为观察实验过程,将刻板的书本知识变为动态实验过程,极大地激发了学生的好奇心和积极性。让学生自主选择观察的样品,提升学生的参与度,使其变为课堂主体,充分发挥学生的主观能动性。趣味性元素的加入提升了学生主动获取知识的能力,让学生了解化学与生活不可分割的关系,培养其科研探索精神和创新能力。Increasing the proportion of interesting can improve the effect of teaching,can consolidate and deepen students'understanding of chemical knowledge.In this paper,this effect is demonstrated by using the experiment of the preparation and characterization of copper sulfate pentahydrate crystals.Observation of the experimental results is changed into observation of the experimental process to display the book knowledge visually,which heavily activates the curiosity and enthusiasm of the students.The students can choose simples to observe using microscope by themselves,this teaching method improves the participation and initiation of the students and let them become the center of class.The interesting element is introduced into class to improve the ability to acquire knowledge of the students.Therefore,the students can know the relationship between chemistry and life,their spirit of scientific research and innovation are also developed.
