根据与实验相关的实验目的、实验仪器、药品 ,通常有以下几种化学实验设计方法。1　根据同一实验目的 ,进行多样性的实验设计。即根据现成的有限的仪器、药品 ,要求学生采用不同的实验方法 ,设计不同的实验方案来达到同一实验目的。例如 :在高三“铁的性质”复习中 ,我要求学生 According to experimental purposes, experimental instruments, and medicines related to experiments, there are usually several methods for designing chemical experiments. 1 According to the same experimental purpose, conduct a variety of experimental designs. That is, according to the limited available instruments and medicines, students are required to adopt different experimental methods and design different experimental programs to achieve the same experimental purpose. For example : In the third grade of “Features of Iron” review, I asked students
