Supplementing reality with non-visible information using the Augmented Reality (AR) technology offers many potentials and opportunities for education [1]. In this way, physical processes can be visualized and explained through an interactive three-dimensional model, e.g. by showing the reaction which takes place in an experiment on a submicroscopic level. For the electrolysis of zinc iodide, we created an AR experience using the Unity engine [2] which visualizes the reaction in such a way. The goal of the app is to provide a model that promotes understanding about electrolysis and facilitates the formulation of the electrochemical half-cell reaction equations. By exploring the app, the electrolysis can be studied interactively, and the animations can be paused, rewind or fast-forwarded as needed. Moving the camera allows users to view the model in overview or detail. In addition, detailed information about the ions, molecules or electrodes can be retrieved via touch input. The development was supported by interviewing ten teacher training students, which feedback helped us to improve the design and usability of the AR app.
