化学是以实验为基础的学科,因此要想理解化学现象,离不开对实验的开展和观察。初中生刚接触化学,只单纯依靠教师的讲解和课本的描述很难理解到化学的实验现象,在教学中,教师可以针对课本,为学生准备较为基础的实验教具来帮助学生更好地学习化学。一、初中化学实验准备化学教师是实验的主要引导者,在实验的准备阶段必须先了解实验内容,根据实验过程和实验目的列出实验所需要的仪器和药品。在部分实验过程中,为了达到完美的
Chemistry is based on the experimental discipline, so to understand the chemical phenomena, can not do without the experimental development and observation. Junior high school students just access to chemistry, relying solely on the teacher’s explanation and textbook description difficult to understand the chemistry of the experimental phenomenon, in teaching, teachers can target textbooks for students to prepare more basic experimental teaching aids to help students better learn chemistry . First, the junior high school chemistry experiment preparation Chemistry teacher is the main guide of the experiment, in the experimental preparation phase must first understand the experimental content, according to the experimental process and experimental purposes to list the required instruments and medicines. In some experiments, in order to achieve the perfect
