An inexpensive self-made apparatus for photochemical experiments was developed and has been tested to facilitate the inclusion of photoreactions in undergraduate teaching laboratories despite budget constraints. The core setup allowing the selection of defined wavelengths in the visible and UV regions is made of commercially available components for less than $500, including an enclosure providing a high safety standard. By choice of the reaction glassware, both reactions on micro scale as well as on preparative scale can be conducted easily in an appropriate time frame. In the Supporting Information, ideas for further optional equipment expanding the setup and enhancing its applicability are presented.

Summary Green hydrogen is a key player in the energy transformation. While the public discourse focuses on green hydrogen produced via photovoltaic or wind power and water electrolysis, this article informs about the state‐of‐the‐art in research on direct water splitting with light. It covers fundamental concepts and processes for water splitting, concrete implementations as well as current challenges for transferring this technology to large‐scale applications. In order to overcome the challenges that remain, it is also necessary to integrate this topic into chemistry education. Experiments, digital media, and teaching concepts developed for this purpose are pointed out. [ABSTRACT FROM AUTHOR]

Light and colour are an inseparable pair that belongs equally to our everyday experiences and to the most controversial concepts of natural philosophical considerations. In chemistry teaching, an experiment‐based approach and a pragmatic interpretation of these terms is necessary that is compatible with the "big five" basic concepts of chemistry education. In this sense, the article presents a panorama of experiments, didactically reduced concepts and teaching/learning materials for teaching chemistry in lower and upper secondary schools.

We present a demonstration involving the oxidative photobleaching of a raspberry juice dye under visible laser light irradiation using the semiconductor titanium dioxide. A plausible interpretation of the phenomenon is discussed that aids in the understanding of semiconductor energetics and the nature of light. (Contains 2 figures.)

In this article, the experimental lecture from the online symposium of the Educational Section of the German Chemical Society GDCh in September 2021 is reproduced in an abbreviated and digitally supported form. It mainly deals with the technical details of the main experiment, the photocatalytic production of hydrogen under school conditions. Based on the steps described, the development of a "school‐suitable" experiment can be prototypically reproduced. [ABSTRACT FROM AUTHOR]

This explorative study is designed corresponding to the principle of the used‐inspired basic research and was carried out with the participation of about 1000 teachers and students from grammar schools and universities. There were 84 lessons carried out at 18 grammar schools, focusing on the relationship between light and colour as well as energy conversions and storage, with special respect to the involvement of light. The collected and statistically evaluated data show a strong correlation between learning outcomes and identification with photochemical contents. Additionally, light energy is considered to be extremely significant for future in school chemistry and in teacher training. [ABSTRACT FROM AUTHOR]

In this paper we give an insight into results from our curricular innovation research which aims at integrating photochemistry in university and school curricula. We have been exploring experimental approaches and developing teaching materials for more than 20 years and most of our experiments and teaching materials have been digitalized and made available in German and English as open educational resources (OER) on our website. The addressed photochemical content can be connected to well‐established subject content at school and university level chemistry, but their theoretical interpretation and the understanding of their applications go well beyond this. However, primarily they should motivate learners to, even after they leave school and university, continue to work on the investigation and development of sustainable processes and materials based on the use of (solar) light.

The purposeful development of novel drugs for the treatment of disease, based on logical considerations of the molecular structure and the structure‐activity relationship, is an especially well suited topic for science classes preparing for the A‐levels. A novel laboratory experiment, reflecting the core principle of drug design by simple methods available in schools, is presented and proposed for integration in chemistry and biology classes.

Starting from A. F. Kekulé's definition regarding the object of research in chemistry, the metamorphosis of the model experiment Photo‐Blue‐Bottle is presented. This experiment has been developed in order to simulate the cycle of photosynthesis and respiration. Based on core concepts of chemistry and safety requirements as well as on commercially available chemicals and light sources, the experiment has optimized step by step. [ABSTRACT FROM AUTHOR]

Translation abstract: Following the principles of photochemical processes and designing clever devices, optical and chemical inputs can be combined according to the propositional logics of Boolean algebra using molecular switches. Doing so, photochromic functional dyes could found application, for example in medicine and in new materials. [ABSTRACT FROM AUTHOR]
