Title: Salinization of the Werra
Driving question: Would you allow the disposal of salty wastewater in river Werra?
Scenario: “Salty wastewater is a by-product in the potassium salt mining process. The company K + S discharges it to the local river Werra. This procedure of disposal is a controversial issue for public discussions. Imagine a public discussion where you have to decide about the problem. After voting you will be interviewed. Give reasons for your personal decision and discuss the arguments.”
Students will look for two kinds of information. First, they will look for information about the pollution of the river and for background information to understand this issue: underlying chemical concepts (e.g. particle model or concentration concept). Second, they will look for different statements concerning the pollution issue: statements for example given by the company or by NGO spokesmen. Based on this information students should form their own decision. Afterwards students will prepare for a whole classroom discussion to finalize their decision.
