Nevertheless, it is often taught in science lessons at primary schools. The following article analyzes a teaching sequence on the subject of "swimming and sinking" in 2nd grade, available as video recording, as well as accompanying material and transcripts. The analysis of the implementation practice serves to examine the realities that result in practical consequence. A sequence from the lesson is analyzed using objective hermeneutics. The method of objective hermeneutics is a reconstructive method in contrast to a subsuming approach. It aims to decipher the typical, i.e. characteristic, structures of phenomena to be investigated and to "bring to light the objective laws operating behind the phenomena". In the case analysis there was maximum transparency: each sequence passage is available as a transcript and as an interpretation, each reader can try to replace the existing interpretation by an even more plausible interpretation using arguments and thereby increasing their knowledge. The case study concludes that the standardized form of knowledge transfer and the schematic view of science overtax children and teachers. The present study provides indications that it must be doubted whether standardized schematic teaching of scientific theory is capable of supporting the development of a researcher's habitus. It provides clues that it should at least be examined whether science education can instead be seen as applied science logic or science pedagogy for children and as science education with the aim of promoting the development of a researcher habitus in children.enAnalysis of science education lessonsswimming and sinkingmethod of objective hermeneuticsquality of teaching370 - Erziehung, Schul- und Bildungswesen01A - Beitrag in wissenschaftlicher Zeitschrift14-22
