化学是以实验为基础的学科,化学实验对于化学课程目标的全面落实具有重要的作用,同时化学实验也是进行科学探究的主要方式,实验探究有利于培养学生的创新思维、创新精神、创新能力.在初中化学实验教学中,作者通过对“万能瓶”这种装置具有贮气、收集气体、干燥气体、气体除杂等多种用途的介绍既对学生进行绿色化学的教育(防止有毒物质污染环境),又拓展了学生的思维能力和资源建设的意识.《义务教育化学课程标准(2011年版)》中指出化学是以实
Chemistry is an experiment-based subject. Chemistry experiments play an important role in the full implementation of chemistry curriculum objectives. At the same time, chemistry experiments are also the main ways to conduct scientific inquiry. Experiments and experiments are conducive to cultivating students’ innovative thinking, innovative spirit and innovative ability. In the junior high school chemistry experiment teaching, the author introduces students’ green chemistry through the introduction of “gas cylinder”, gas collection, dry gas, gas impurity removal and other purposes (to prevent toxic substances Pollution of the environment), but also expand the students’ thinking ability and awareness of resource construction. “Compulsory Education Chemistry Curriculum Standards (2011 Edition)” pointed out that chemistry is based on solid
