The short explanation of photosynthesis was created during a workshop week at the Fachhochschule St. Pölten. The title of my workshop was: Visualisation of teaching and learning videos without narration. My fellow student and I wrote a text about photosynthesis in the course of this workshop in order to create an explanatory video from it. I was under time pressure because the project had to be finished within the week and had to be presented to the other workshop participants and teachers.
