化学是一门以实验为基础的学科,化学实验对于激发学生学习化学的兴趣,形成化学概念,巩固和理解化学知识,培养学生观察现象、分析问题、解决问题的能力。初步掌握一些常用的化学实验技能,培养学生实事求是、严肃认真的科学态度和科学方法。可见,化学实验既是化学教学的重要手段,又是学习化学的基本方法,也是激发学生学习化学兴趣的源泉。 Chemistry is an experiment-based discipline. Chemistry experiments are of interest in stimulating students ’learning chemistry, forming chemical concepts, consolidating and understanding chemical knowledge, developing students’ ability to observe phenomena, analyze problems, and solve problems. Preliminary grasp of some commonly used chemical experiment skills, develop students seeking truth from facts, serious and serious scientific attitude and scientific methods. Visible, chemical experiments both an important means of chemistry teaching, but also the basic method of learning chemistry, but also stimulate students to learn the source of chemical interest.
