A "research box" is an interactive exhibit comprising the implementation and evaluation of experiments, where visitors (here mostly pupils from 9-12 years) are not only encouraged to activity but also to reflection. The development is done with regard to design and suitability as learning environment. Evaluation of the exhibit is done by participant observation of pupils. Thereby a prolonged cognitive engagement with the physical content of the exhibit becomes apparent.
