化学学科是离不开化学实验的,化学实验能让每一个学生以轻松愉快的心情去认识多姿多彩、与人类生产生活密切相关的化学,积极探究化学的奥秘,形成持续的化学兴趣,增强学好化学的积极性和主动性;也能让每一个学生得到平等的动手机会,逐步学会分析和解决与化学有关的一些简单的实际问题;更能让每一个学生有更多的机会主动地去体验探究性学习的过程。本文以“实验室制取氧气”为例,谈谈初中化学实验的重要作用。 The science of chemistry is inseparable from chemical experiments. Chemistry experiments enable every student to understand the chemistry that is closely related to human production and life in a relaxed and happy mood, actively explore the mysteries of chemistry, and form a continuous interest in chemistry. Learn chemistry enthusiasm and initiative; also enable every student to get equal opportunities for mobile phones, and gradually learn to analyze and solve some simple practical problems related to chemistry; better enable each student to have more opportunities to actively experience The process of inquiry learning. In this paper, “Oxygen in the laboratory” is taken as an example to discuss the important role of junior high school chemistry experiments.
