化学是一门以实验为基础的自然科学。化学实验的发展在化学学科发展和化学教学中占有相当重要的地位。初中化学实验教学可以激发学生对化学的兴趣,激活学习的内动力,也可以在某些程度上帮助学生降低对化学知识重点、难点的理解,促进学生认知和掌握化学知识,还可以在化学实验教学的过程中训练学生的科学实验操作技能和观察能 Chemistry is an experiment-based science. The development of chemical experiments occupies a very important position in the development of chemistry and chemistry teaching. Junior high school chemistry experiment teaching can arouse students ’interest in chemistry, activate the internal motivation of learning, and to some extent help students to reduce their understanding of chemical knowledge’s key and difficult points, promote students’ cognition and mastery of chemistry, Training students in the process of experimental teaching of scientific experiment skills and observation skills
