In this double lesson, the concept of obsolescence is introduced using the example of electronic devices. The students work in groups to analyse the forms of obsolescence and inform the group in short presentations. They discuss planned, functional and psychological obsolescence, as well as planned excess consumption and indirect wear and tear. This discussion of the extent to which each individual contributes to obsolescence and its consequences offers the opportunity to revisit the core topics of the teaching unit and place them in a wider context. The students then discuss together what options exist for reducing obsolescence.

For this double lesson, PCs/laptops are required for three groups. It makes sense to provide different rooms for the group work. The groups will receive Power Point presentation slides for preparation and presentation, which they can work on. A projector and loudspeakers are therefore required for the presentation.
