Seltene Erden
Gewinnung, Produktion, Wiederverwertung
Der technische Fortschritt versorgt die Menschheit zuverlässig mit innovativer Technologie. Dies hat die Nachfrage nach spezifischen Rohstoffen, etwa für Mikrochips, Rußpartikelfilter, und Dauermagneten sprunghaft steigen lassen. Metalle wie Lithium, Cer, Neodym und weitere gehören zu den sogenannten „Seltenen Erden“. Der Bedarf nach ihnen hat große geopolitische Auswirkungen, und hat zum Aufstieg Chinas, das den Großteil der Lagerstätten auf seinem Gebiet birgt, entscheidend beigetragen. Der Film geht der geopolitischen Bedeutung der Seltenen Erden ebenso nach, wie er deren Verwendung und Gewinnung zeigt. Abschließend werden Möglichkeiten gezeigt, den Bedarf an Seltenen Erden (und damit eine strategische Abhängigkeit von China) durch effektives Recycling zu reduzieren. In Verbindung mit dem umfangreichen Zusatzmaterial (Arbeitsblätter, interaktive Aufgaben, Glossar, Testfragen) lässt sich das Medium hervorragend im Unterricht verwenden.

Product Piracy
Counterfeiting takes place in almost all economic sectors – textiles, watches, car parts, machine parts, tools, accessories, software and medicines. Some counterfeits are easy to recognise, others are so well-executed that even experts have difficulty distinguishing between original and imitation. This DVD covers the development of a product from idea to manufacture. Once a product has become a trademark, product pirates appear on the scene.
Peer Mediation
Lena and Max attend the 7th form. Max is new in class. During a break, Max notices that Lena and her friend are laughing at him again. Max loses his temper! He slaps Lena in the face. That hurts and Lena runs back into the classroom with a red cheek. The growing conflict between the two has escalated. Just like Lena and Max, every day pupils all over Germany have rows with each other. At the Heinrich Hertz Gymnasium in Thuringia, pupils have been trained as mediators for years. At set hours, they are in a room made available by the school specifically for mediation purposes. The film describes the growing conflict between Max and Lena and shows a mediation using their example. In doing so, the terms “conflict” and “peer mediation” are explained in a non-technical way. The aims of peer mediation and its progress in five steps as well as the mediators’ tasks are illustrated. The art of asking questions and “mirroring”, which the mediators must know, is described and explained. Together with the comprehensive accompanying material, the DVD is a suitable medium to introduce peer mediation at your school, too.
