化学是一门与生活息息相关的学科,在许多学生眼里,化学似乎带有一种神奇的色彩,化学现象其本身变化多端,而且还需要用“分子”“原子”理论来力求解释,因此学生们就会有这样的感慨:化学抽象难学。化学是以人们周围存在的物质为研究对象。化学在生活和生产中能使无用变有用,一用变多用,化害为利。掌握了化学知识,就可使自然资源更好地为人类服务。 Chemistry is a discipline closely related to life. In the eyes of many students, chemistry seems to have a miraculous color. Chemical phenomena are themselves varied. They also need to be explained by the theory of “molecules” and “atoms” , So students will have such a feeling: chemical abstract difficult to learn. Chemistry is based on the material that exists around people as the research object. Chemistry in the life and production can make useless useful, one with more use, damage for the benefit. With chemical knowledge, natural resources can serve humanity better.
