Electricity
From Turbine to Socket
How is the electricity generated with which we power our appliances in everyday life? The magic words are ‘charge‘ and ‘voltage‘. Electricity is created when bodies have different charges. If you rub a balloon with a cloth and hold it close to your hair, the hair is attracted by the balloon. By friction the balloon is charged, thus a voltage is generated between the balloon and the hair. Objects that are differently charged attract each other and the voltage tends to balance itself. As a rule, matter is neutral. That means the atoms bodies consist of have an equal amount of positive and negative charges. But if you rub specific materials like the balloon and the cloth here, the charges are separated. The electrons with their negative charge are transferred to one object, whereas the other object is charged positively. However, as matter seeks a balance and wants to equalise the charges, the opposites attract each other. And the greater the separation of the charges, the higher the voltage, and the higher the voltage, the more objects are attracted and seek a balance. You realise how important and self-evident electricity has become in our everyday lives only when it is no longer there. At home, household appliances run by electricity would not work anymore. The refrigerator would not cool anymore, the heater would not heat anymore. No washing machine, no telephone, no television, no game consoles – and, of course, we would suddenly be plunged into darkness if the light went out. Even a flashlight would not help because it works with electricity as well even though this electricity does not come from the socket but from a battery. Without electricity we would actually be in the dark.

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.
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.
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.
