化学实验是化学教学不可缺少的重要组成部分,它对于帮助学生认识物质的性质及变化规律、掌握物质组成和结构等知识具有十分重要的意义。实验的改进能使实验易操作、更直观、更安全,达到探究活动的目标。
Chemistry experiment is an indispensable part of chemistry teaching. It is of great significance to help students understand the nature and variation of matter, and grasp the knowledge of matter composition and structure. The experimental improvement can make the experiment easy to operate, more intuitive and safer, and achieve the goal of exploring activities.
