Electrolysis of Sodium Chloride (Brine)

This is a learning mat to get the students to understand the electrolysis of sodium chloride for themselves. The students work in pairs to go through the storyboard, writing on post-it notes what they see. They then complete the worksheet which can be self assessed. I have found that it gives them a better understanding of what happens at the electrodes and helps them to understand half equations much more easily.
