化学是一门以实验为基础的自然科学,它与社会环境十分密切,环境污染和环境保护往往都蕴含了一定的化学因素,在化学教学中渗透环保教育是每个化学教师义不容辞的责任。本文就如何在中学化学教学中渗透环保教育的问题从教材素材、实验要求、生活实际、第二课堂这四个方面进行了探索。
Chemistry is an experiment-based natural science. It is closely related to the social environment. Environmental pollution and environmental protection often contain certain chemical factors. It is the unshirkable responsibility of every chemistry teacher to penetrate environmental education in chemistry teaching. This article explores how to infiltrate the environmental education in chemistry teaching in secondary schools from the four aspects of teaching materials, experimental requirements, life reality, the second class.
