On the following pages you will find a digital learning unit to introduce the differentiated atom model.

There are two versions of the learning unit. One for use in lower secondary school and one for use as a revision unit in upper secondary school. The two versions differ only in a few places or in some building blocks in order to meet the expected performance level of the students of the corresponding grade.

The unit was created by Mark-Tilo Schmitt as part of his doctoral project and is based on the currently valid (01.08.2015) Lower Saxony core curriculum for the subjects of physics, chemistry and biology in grades 5-10 of the Gymnasium.
