硫酸铜溶液与铁钉的反应是教科版六年级下册第二单元第6课“化学变化伴随的现象”中的一个案例。在实际教学中,通过材料铁钉,循环利用硫酸铜溶液和铁钉等,实现实验过程的可循环,从而使改进该案例与所属单元前后教学衔接顺承,同时实验更具可操作性、实验材料可回收,实现了实验教学的科学性。
The reaction of copper sulfate solution with nails is a case in Lesson 6 of the second unit of the sixth grade undergraduates in the textbook, Phenomena of Chemical Change. In the actual teaching, the experimental process can be recycled through the material nails, the recycling of copper sulfate solution and the nails, so that the improvement of the case with the teaching of the unit before and after the succession, at the same time the experiment is more operable, the experiment Material can be recycled, to achieve the experimental teaching of science.
