化学是一门以实验为基础的自然科学,以实验为基础是化学学科的重要特征.实验能为化学学习提供必要的感性材料,有利于学生理解化学概念和原理,形成科学的思想和观念;能为学生提供练习和实践的机会,有助于培养学生的观察能力和思维能力,提高实验操作技能;能激发学生学习化学的爱好,增强学习动机,调动其学习积极性;能帮助学生理解、把握、应用、检验和巩固有关的知识、技能,继续前人积累的最基本的经验,
Chemistry is an experiment-based natural science which is an important feature of chemistry based on experiments.Experiments can provide the necessary perceptual material for chemistry learning, help students to understand the concepts and principles of chemistry, and form scientific ideas and concepts. Can provide students with practice and practice opportunities, help to develop students’ observation and thinking skills, improve experimental skills; can stimulate students to learn chemistry hobbies, enhance learning motivation, to mobilize their enthusiasm for learning; can help students understand and grasp , Apply, test and consolidate relevant knowledge and skills, and continue the most basic experience accumulated by our predecessors,
