化学是一门建立在实验基础上的自然学科,化学实验是中学化学教学中一个非常重要的环节.随着素质教育理念的不断深入,化学学科培养学生综合素质方面的优势越来越受到广大教师的关注.相较于以往,化学实验在化学教学活动中的比例越来越高.然而,随时实验数量的增加,有关实验的污染问题也变得越来越突出了.一、中学化学实验污染现状与其它的实验相比,化学实验在污染性方面往往较强,据了解,中学阶段所做的化学实验中,有毒实验要占到一半以上.
Chemistry is a natural subject based on the experiment.Chemical experiment is a very important link in the chemistry teaching of middle school.With the continuous deepening of the philosophy of quality education, the advantages of chemistry in cultivating students’ comprehensive qualities are more and more accepted by the majority of teachers Of the concern.Compared with the past, the proportion of chemical experiments in chemistry teaching activities is getting higher and higher.However, with the increase of the number of experiments at any time, the pollution problems about the experiments also become more and more prominent. Compared with other experiments, chemical experiments tend to be more polluting. It is understood that more than half of the toxic experiments in secondary chemistry experiments are conducted.
