The principles of green chemistry can be communicated by means of didactically concise experiments and by relating them to a large variety of key terminology in chemistry. Here we report on innovative experiments in video tutorials, animations and other digital media in which light is involved as a form of energy. A tested and evaluated teaching module on the carbon cycle in animate nature applying several of these experiments and digital media is presented. All these materials enable the communication of basic concepts of chemistry didactics in Germany and contribute to the integration of green chemistry into the school curriculum.
