化学是以实验为基础的学科,初中生学习化学知识能够加深对大自然现象和运行规律的认识,丰富知识结构。在我国,实验在初中化学教学中占有重要地位,通过化学实验学生加强了对知识的印象,有效地将理论与实践结合起来。实验是化学学习的重要组成部分,是化学学科不断发展的基础,初中生加强实验教学,是学好化学的重要步骤,也是加深理解的有效途径。所以每个学校都非常重视实验教学,花大力气完善实验药品和器材,在教学内容中也加入了许多有趣又贴近生活的实验。因 Chemistry is based on the experimental discipline, junior high school students to learn chemical knowledge can deepen the understanding of nature phenomena and operating rules, enrich the knowledge structure. In our country, the experiment occupies an important position in chemistry teaching in junior middle school, strengthens the impression of knowledge through chemistry experiment students, and effectively combines theory with practice. Experiments are an important part of chemistry learning and the basis for the continuous development of chemistry. Strengthening junior high students’ experimental teaching is an important step to learn chemistry and an effective way to deepen their understanding. Therefore, each school attaches great importance to experimental teaching, make great efforts to improve the experimental drugs and equipment, teaching content also joined many interesting and life-like experiments. because
