Acids and Bases
In Everyday Products
We can find acids and bases in every supermarket, some of them in our food, others in cleaning agents. In everyday products, acids and bases as well as acidic and alkaline reacting salts have extremely different functions. In food, acids are either present or added as flavouring agents such as citric acid, tartaric acid and acetic acid, as antioxidants such as ascorbic acid or generally as acidifiers, sequestrants (citric acid and tartaric acid) and preservatives (acetic acid). In baking powder acidic salts (phosphates or tartar) react with soda as a raising agent – by means of a chemical reaction, carbon dioxide is formed as a gas. The film shows where we find acids and bases in our everyday life and what functions they have. The acid-base theory of the physico-chemist Arrhenius is explained just as Brønsted’s definition. Simple and interesting experiments encourage the pupils to perform their own tests. The comprehensive accompanying material includes information for further or in-depth discussion of the subject of acids and bases at school. The DVD was compiled in cooperation with the well-known professor of chemistry Georg Schwedt.

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.
Inclusion
Madita is eleven and blind. She does not want to go to a special school but to a regular grammar school. She says she feels "normal" there. Jonathan is eight and has a walking disability. He likes going to the school where he lives. Here, his best friend sits next to him. Max Dimpflmeier, a teacher who is severely deaf, explains that school life is not easy. Quote Max Dimpflmeier: "You don't want to attract attention, you want to avoid saying that it is necessary for you that 70 people adjust to your situation." People on their way to inclusion.
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.
