Batteries
From Production to Recycling
A battery is a portable source of chemical energy, which is converted to electrical energy as soon as the battery is placed in a circuit. The main principle is the same in almost all batteries. A metal that forms the negative terminal is opposite a positive terminal. The positive terminal is also called anode, the negative terminal cathode. Between the two terminals there is an electrically conductive liquid, the so-called electrolyte. As soon as a battery is placed in a circuit, positive and negative terminals are connected via an external contact and electrolysis takes place. On the way, a current flows from anode to cathode

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.

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.
