An experiment simulating the natural cycle of photosynthesis and respiration-and dealing with both matter and energy conversion-is presented and theoretically elucidated. Teaching recommendations concerning the integration of the Photo-BlueBottle experiment into lower chemistry and biology education according to the 5E Instructional Model are provided as well as supplementary materials.

<p>Five open access video tutorials concerning photochemistry for science education are presented. They address especially teachers and students, but can serve also for making photochemistry accessible to the wide public. The common format of the five tutorials is a dialogue between the young   layman   Niklas   and   a   young   scientist   who   introduces   him   into   different   topics   of photochemistry. These topics correspond to three common core concepts in worldwide chemical education: <em>structure/property-relationships</em>, <em>equilibria</em>, and <em>energy</em>. Teaching recommendations are given, as to how the tutorials can be beneficial for science lessons.</p>

This paper underlines the ongoing necessity of innovating school chemistry curricula in Germany, while acknowledging that both regular chemistry and CLIL chemistry lessons rely on the same governmental guidelines. In order to achieve curricular innovation successfully, cutting-edge curricular innovation research should be combined with participatory action research (PAR). There is no network of collaborating bilingual chemistry teachers. Therefore, a database of CLIL chemistry in Germany is created and a needs analysis is conducted to identify possible topics serving as starting points for innovation. The needs analysis focusing on the teachers’ demands as regards bilingual teaching materials addressed teachers of bilingual chemistry throughout Germany. The questionnaire comprises an open and a closed part. Additionally, CLIL biology teachers from North Rhine-Westphalia were included. The research reveals the respondents’ great demand in many key topics in chemistry and/or biology curricula. There is a particular interest in material for photosynthesis/respiration. A topical database of bilingual chemistry provision in Germany and bilingual biology provision in NRW was created. The survey helped select one innovative topic. Based on this, teachers will be recruited for PAR. Moreover, the teachers’ answers have reaffirmed current efforts into the development of bilingual chemistry teaching materials.
