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>
