Electrolysis of Water

We did this activity today. I was a bit concerned as we had very limited time but am glad to say that they got it done and saw it work!!! YAY!!! We saw a video that showed the splint test and explained combustion of the gas. We did not do the splint test in class but they did see the gas bubbles and were able to grasp that there was more hydrogen than oxygen.
