化学实验是学习初中化学的基础,是科学探究的主要方式,通过实验探究,可以学习化学基础知识,理解化学基本原理,研究化学常见问题,培养学生良好的科学态度。一、学生生活中的化学知识无处不在在进行系统的化学知识学习之前,学生在日常生活中就接触了大量的化学知识。例如学生早餐常吃的松软可口的馒头就是面团经过发酵制成的,而发酵过程中会产生乳酸,为了中和掉乳酸,需要加入一些纯碱与其反应。有些外地来的学生,刚开始
Chemistry experiments are the basis for learning chemistry in junior high schools. It is the main mode of scientific inquiry. Through experimental exploration, we can learn the basic knowledge of chemistry, understand the basic principles of chemistry, study common problems in chemistry, and develop students’ good scientific attitude. First, the chemical knowledge in student life is ubiquitous In the systematic chemical knowledge learning, students exposed to a large number of chemical knowledge in their daily lives. For example, students eat breakfast bread is soft and delicious bread dough is fermented, and the fermentation process will produce lactic acid, in order to neutralize lactic acid, need to add some soda reaction. Some foreign students, just started
