This mediation exercise focuses on mediating from English to German, as it is required in the Realschulabschluss- und Hauptschulabschlussprüfungen in Germany. First, the students have to read an authentic national park warning sign about rattlesnakes and have to make sense of it. Second, they have to think about mediating it into German for their parents. The exercise offers German -English vocabulary help or English-English vocabulary help, so that you have a natural differentiation for your students.
