化学是一门实验性很强的学科。以化学反应为基础的实验统称为化学实验。它在化学教学中占有十分重要的地位,是化学教学中不可分割的组成部分。通过化学实验可以帮助学生熟悉化学概念,理解和巩固化学知识,正确掌握实验的基本方法和操作技能,培养学生求实的科学态度、严谨的科学作风,辩证的科学方法,训练学生的观察、思维和独立操作能力 Chemistry is a highly experimental discipline. Chemical reaction-based experiments are collectively referred to as chemical experiments. It occupies a very important position in chemistry teaching and is an integral part of chemistry teaching. Through chemical experiments, students can be familiar with the concept of chemistry, understand and consolidate knowledge of chemistry, correctly master the basic methods and operational skills of experiments, cultivate students’ scientific attitudes for seeking truth, and rigorous scientific style, dialectical scientific methods, and train students’ observation and thinking.
