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.

The Daily Newspaper
Every day, there is a surge of news reaching us via different news channels. In spite of TV and Internet, the daily paper still is one of the most important main sources of news. But how is a newspaper created? The film shows the production of a paper in the course of one day. Starting with the editorial meeting in the morning, in which the topics and deadlines are determined, the film accompanies a journalist during her research work. You can see how a journalistic interview is conducted and what the photographer must consider when taking a press photo. Back in the editorial office, the editor’s work is illustrated, which includes the page layout and the writing of an online article in today’s time. Impressive pictures from the printing centre depict the process from the digital page to the finished newspaper. Together with the comprehensive accompanying material, the DVD is perfectly suited for use at school
Copyright
Copyright is subject to constant change to keep up with technological advances. This film enables the viewer to grasp the basic principles of this extremely intricate matter. By way of introduction, the film defines what an author is, what kinds of works there are and how long a work is protected on principle. Then the fundamental rights of an author are cited and it is shown how these are exploited in our times. In the third chapter, the respective rights are illustrated by way of practice-oriented examples of books, photos, music and films. Here, of course, an emphasis is laid on the field of education, taking into account the latest case law within the EU and Austria in particular. A further chapter highlights the problems arising with the Internet and goes into the citation law and pirate copies. All in all, in this way the viewer is made familiar with the most important basic terms and their meanings. Comprehensive worksheets and additional accompanying material invite us to deepen our knowledge of the subject.
