Ecosystem Lake
Freshwater Fascination
Lakes are stagnant waters that look quite peaceful to us. But the quiet is deceptive: above and below the water surface, life is anything but peaceful. Phytoplankton and zooplankton are eaten by small predators such as polyps or hydrachnidiae. Toebiters, dragonfly and beetle larvae are food for the water scorpion. As every animal feeds on different prey and in turn is eaten by various predators, a food web is created. The amount and variety of the lake inhabitants depends on the concentration of nutrients. In clear lakes, aquatic plants may spread down to a depth of 10 metres. Different zones with particular plant species are clearly visible. Also animals above the water profit from the rich underwater life, for example the waterfowl. Ever since the lake was formed, wind and waves have been carrying dead plants and animals to the shore, where they have sunk down and decomposed. At the same speed at which the lakeside grows, the water surface of the lake shrinks. With its extensive additional material the didactic DVD is ideally suited for use in the classroom.

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.
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.
