Earthworm
Structure and Behaviour
It is slippery, soft and slimy, burrows in the moist soil and many just find it disgusting – the earthworm. Most of us know it when it comes to the surface in heavy rain and ends in puddles or, possibly, as fish bait; but earthworms are true natural wonders and extremely useful. Only a very small percentage of all animals are vertebrates. These animals, such as mammals, birds, reptiles, amphibians and fish, all have a vertebral column. Over 90% of our fauna are invertebrate animals.

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.
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.
Air Traffic
Being able to fly has been a dream of humanity from time immemorial. But it does not even date back a century that people actually started being able to travel through the air. Since the 1960s, the number of flight passengers has been constantly increasing. Thus, the airspace is no longer dominated by birds but by man-made flying objects.
