Electrodes (or half cells) are easy to understand with our unique model that shows how electrons and ions behave in them.
Your students first build their easy to make paper models of electrodes. They use these to see how electrical potential is formed by different electrodes and how this is measured using a hydrogen electrode with voltmeter. The differently coloured electrons make it easy to see how the electrons behave.
The model can be used to show zinc electrode, copper electrode and standard hydrogen electrode. It explains the concept of electromotive force (E or emf) and the need for standard conditions.
Optional - you can use the model to introduce the electrochemical series.
