化学实验作为化学教学的重要组成部分,担负着对学生进行环保教育和培养学生严谨的科学态度的重要职责,并且较之课堂教学更具有直观性。因此,要求教师身体力行,无论在演示实验还是分组实验时,都要注意减少污染,厉行节约。一方面,严格按照实验操作的要求,节约用量,减少耗材,现象明显,废弃物品不随意丢弃、排放,另一方面,尽量创造条件,改进实验方法。我本着节约药品、操作简单、避免不必要的浪费,在实践 As an important part of chemistry teaching, chemistry experiment plays an important role in carrying out environmental education and cultivating students’ rigorous scientific attitude, and is more intuitive than classroom teaching. Therefore, requiring teachers to practice, both in demonstration experiments or group experiments, we must pay attention to reduce pollution, strict implementation. On the one hand, in strict accordance with the requirements of experimental operation, saving consumption, reducing supplies, the phenomenon is obvious, discarded items are not discarded, emissions, on the other hand, try to create the conditions to improve the experimental methods. I am in the saving of drugs, simple operation, to avoid unnecessary waste, in practice
