微型化学实验是用尽可能少的化学试剂获得比较明显、清晰的反应结果和化学信息的一种实验方法.其特点是实验药品微量化及实验仪器微型化,可以减少试剂用量,降低实验排废量,减少环境污染,缩短实验时间,并且安全可靠.在化学教学中引入微型化学实验,不仅能激发学生的学习兴趣,使学生更好地理解理论教学内容,而且能培养学生的实验、观察、思维、自学等多方面的能力,对提高学生素质起着重要作用.一、培养实验能力实验能力的培养是化学教学中最基本的内容之一.在
Micro-chemical experiment is an experimental method to obtain obvious and clear reaction results and chemical information with as few chemical reagents as possible, which is characterized by the miniaturization of experimental drugs and the miniaturization of experimental instruments, which can reduce the dosage of reagents and reduce the emission of experimental waste Reduce the environmental pollution, shorten the experiment time, and be safe and reliable.It is not only stimulating students ’interest in learning, but also enabling students to better understand the theoretical teaching content, and can cultivate students’ experiment, observation, Thinking, self-learning and other aspects of ability, to improve the quality of students plays an important role.First, to cultivate experimental ability Experimental ability of chemical education is one of the most basic content in
