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.

Podcasting
Today, the use of new media has become a matter of course not only in everyday life – schools and teaching, too, benefit from the new technologies and methods, which support active and independent learning. Especially in computer science, ethics and language courses but also in all other subjects, modern media are a valuable pedagogic and didactic asset. This DVD uses the example of podcasts to demonstrate how the possibilities opened up by new media can be applied in the classroom and how the pupils can be taught to handle them in a competent and target-oriented manner. The film is aimed at supporting the use of podcasts at school and encourages making them. This also requires the ability to find information on the Internet and assess it. The film informs on the functionality of podcasts and technical background as well as on the teaching and learning possibilities offered by podcasts – ranging from specific contents to superordinate learning targets such as the advancement of creativity and team spirit. The DVD is a useful support for teachers applying new media and wishing to show their pupils how to handle Running Time: 20:29 ms them in a sensible way.
