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.
Mobile Learning II
Oh, what’s that? Original soundtrack Thissen: “As our children grow up in a media world and naturally handle the media, they should also be a topic in school.“ An older child says the point is that they don’t just load down apps but create things themselves that haven’t existed so far. Hi, I’m Jana. A propeller hat. I’ll put it on. Now I’m no longer a simple rhino, but a flying rhino. Original soundtrack Thissen: “It’s exactly the great flexibility of tablets that promotes very personalised and adapted learning.” Original soundtrack Welzel: “It’s fascinating to see how the children grow with their products and how they always want to improve them.” The Westminster Abbey is a church in London for the royal family. Original soundtrack Welzel: “And?“ They think it is ok.
Ceramic
Ceramics are indispensable in our everyday lives. We eat from ceramic plates, drink from ceramic cups, use tiled ceramic bathrooms. But how is ceramic manufactured? The film reveals the secrets of this fascinating material! We get to know more about the beginnings of ceramic in the Old World of Egypt and Mesopotamia, about Greece, China and Rome. We gain interesting insights into the valuable earthenware and are also shown the exquisite further development of the "white gold". Today this versatile material is irreplaceable in industry, too. Whether in space or as an easily compatible substitute in medicine, ceramic is applied in many places.
