Gummi
Der flexible Alleskönner
Heutzutage einen Industriezweig zu finden, der ohne Gummi auskommt, ist denkbar schwierig. In dieser Folge gehen Joey Grit Winkler und Fero Andersen der Frage nach: Was ist Gummi eigentlich und wie wird er hergestellt?
Die unentbehrliche Grundlage für Gummi ist Kautschuk, der weiße Saft des Kautschukbaumes. Dieser Baum kam ursprünglich nur in Südamerika vor und so waren es alte, südamerikanische Hochkulturen, die vor über 800 Jahren Kautschuk nutzbar machten, indem sie ihn zu einem Ball formten, um einem rituellen Ballspiel nachgehen zu können. Auch heute ist Kautschuk die Grundlage schlechthin für Gummi. Kautschukbäume werden allerdings nicht mehr nur in Südamerika, sondern in tropischen Gebieten rund um den Globus angebaut: Die Nachfrage nach Gummi auf dem Weltmarkt ist enorm.

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.
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.
