Photo processes, which are indispensable for sustainable development, have not yet been adequately represented in educational policy guidelines (KMK and state guidelines on ESD). Although the principles of "green chemistry" and sustainability are increasingly being addressed in chemical education publications, light as the most sustainable form of energy and chemistry with light remains underrepresented here as well. In this paper, freely accessible digital resources produced by the Didactics of Chemistry are presented for the development of ESD‐relevant teaching/learning content that focuses on light as a form of energy. In it, photochemical expertise and pedagogical principles are brought together in scientifically consistent and didactically concise formats. It can be accessed via established teaching contents. Its use by learners should definitely be guided or at least moderated by teachers, whereby in the sense of systemic thought processes, the contents dealt with should not only be considered in isolation, but should be brought into larger contexts. [ABSTRACT FROM AUTHOR]

Presents an experiment on photogalvanic cells for classroom investigation. Principles to be used in teaching photochemistry. List of chemicals used during the experiment; Hazards involved in the experiment.

The article focuses on a demonstration that involves the oxidative photobleaching of a raspberry juice dye under visible laser light through the aid of semiconductor titanium dioxide. It explores the plausible interpretation of the phenomenon that supports the understanding of nature lights and semiconductor energetics.

The article presents a laboratory experiment to help first-year undergraduate analytical chemistry students understand the concept of simultaneous electrochemiluminescence (ECL). It describes the phenomenon of ECL using an electrochemical cell to illustrate the reaction of luminol with hydrogen peroxide. Information on equipment and materials used, procedure, safety considerations, and discussion topics is provided.
