Zwei Erkenntnisbereiche, die zueinander gehoren Wie das Verhaltnis zwischen der Makro- und der Mikrowelt in der Schule thematisiert werden kann

摘要

The existence of molecules, atoms and elementary particles can be viewed as a fi rmly and permanently grounded fact. As science historian Ernst-Peter Fischer has said, whoever claims to be scientifi cally literate must have learned the “lesson on atoms”. In this presentation we place these statements in an instructional context. First, we look at the relevance of the Einstein mass-energy equivalence relation to chemistry. Then we look at the aspects of quantum physics that can infl uence chemistry instruction, as they span the divide between the portions of matter that one sees on a lab bench and the quantum-physical units from which our models say they are built (that is, atoms, elementary particles etc.), or into which our models say that they can be separated into. We will show two classroom scenarios that can be used to introduce the particle concept.
