本单元实验较多,操作比较简单。教师在教学中,应根据学校的具体情况,尽量创造条件,采用“边讲边实验”的教学方法。这样既便于学生的观察,又可以增强学生对化学的兴趣。1演示实验分析与教法建议[实验10-1]酸、碱指示剂实验分析在初中,我们只要求学生掌握石蕊和酚酞两种指示剂。 This unit has many experiments and the operation is relatively simple. In teaching, teachers should try their best to create conditions according to the specific conditions of the school, and adopt the teaching methods of “talking while experimenting”. This will not only facilitate students’ observation but also increase their interest in chemistry. 1 Demonstration Experiment Analysis and Teaching Suggestions [Experiment 10-1] Experimental analysis of acid and alkali indicators In junior high school, we only required students to master the two indicators of litmus and phenolphthalein.
