3D Printing
Methods, Materials, Future Prospects
Layer by layer, a three-dimensional form is being created here – a chess piece. Just like that, from a printer – however, a special one: a 3D printer. Thus, the dream of being able to manufacture three-dimensional pieces yourself at home becomes reality. In industry, professional 3D printers play an increasingly important part. Different methods and materials enable the production of a broad variety of objects. This ranges from workpieces to medical demonstration objects to model pieces and even foods, like marzipan in this example. The possibilities of application seem to be almost unlimited. As preferred materials, different plastics and metals are primarily used. With this method, a whole new kind of production becomes possible. Material that has so far been reduced or formed by processing is expanded here step by step. Therefore, this is also referred to as additive manufacturing, i.e. manufacturing by addition. But how exactly does a 3D printer work? What is it already able or still unable to do today? And will this technology have an impact on our work life?

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.
Rights and Obligations
Three girls of different ages: Anna is 17, Paula 15 and Lena 13. Before the law, their respective ages have consequences – because children and adolescents have different rights and also obligations.
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.
