在学习导体和绝缘体时,老师让找们用实验研究盐水能否导电.课堂上许多同学实验成功了,小灯泡亮了,可我们却失败了,小灯泡没有亮,每个小组的器材是一样的,为什么我们的小灯泡不亮,影响盐水导电的因素到底有哪些?我们决定课后对盐水导电这个问题进行深入研究. When learning conductors and insulators, the teacher asked them to use experiments to test whether the saltwater could conduct electricity. Many students in the classroom experimented successfully. The light bulbs were bright, but we failed. The light bulbs did not light. The equipment of each group was the same. Why do we have a small light bulb that does not light, what are the factors that affect the conductivity of salt water? We decided to conduct an in-depth study on the issue of salt water conduction after class.
