The Beaver
Natural river and lake areas are becoming increasingly rare. With expensive measures to restore them to their natural state, efforts are being made to recreate them. Here, an animal may be helpful: the beaver. After it was exterminated in Germany in the 19th century, today about 15 000 specimens live here again thanks to the reintroduction of the beaver during the 1960s. Many people, however, have never caught sight of this shy nocturnal rodent, yet. The DVD first describes the beaver (in particular its adaptation to life in water) and zoologically classifies it. Then the beaver family and their social behaviour and habitat are introduced. The beaver constructions (beaver dam and beaver lodge) are illustrated as well as its territory and its purely vegetarian diet. Subsequently, both its extermination and its reintroduction as well as present-day problems are looked into. But primarily the film shows the beaver to be a valuable, natural architect of landscapes.
Learn moreBiodiversity
The exact numbers of plant and animal species on earth are unknown. What we do know, though, is that there is a dramatic decline in the variety of species mainly triggered by man. The "threats to biodiversity" as well as their causes are the topics of this film. It illustrates the reckless exploitation of the resources of the earth on land and in the oceans.
Learn moreFish Farming
Lakes, rivers and streams are the natural habitats of our freshwater fish. Some of them, such as carp, trout and char, are eaten as food fish. But where do the fish come from and why have our lakes and rivers not been fished dry yet? Since the Stone Age people have been catching fish for subsistence. Fish is an important source of protein. With a wide variety of methods, such as fishing rods or nets, we hunt them successfully.
Learn moreKräuter und Gewürze
Das Wort Kräuter kommt von Kraut. Als Kraut bezeichnet man meist die oberirdischen Teile einer Pflanze, aber was ist mit den Wurzeln? Das Wort wiederum steckt in Gewürz. Blattgewürze werden nur als Gewürz bezeichnet, wenn sie getrocknet sind. Im frischen Zustand zählen sie zu den Kräutern. Fest steht, eine klare Abgrenzung gibt es nicht. Viel wichtiger ist es, ein paar Kräuter und Gewürze zu kennen, um sie im Alltag richtig einzusetzen.

Ein vermeintlich gewöhnliches und billiges, weißes Gewürz gilt im Altertum als Göttergabe, in unserer Zeit kann man es kiloweise im Supermarkt kaufen. Die Rede ist von Salz, der chemischen Verbindung aus Natrium und Chlorid.
Learn moreStarling
In general, male and female starlings look very much alike. In spring, starlings assume their nuptial plumage, in autumn, after moulting, they wear their eclipse plumage.
Learn moreHare and Rabbit
How do we distinguish between a hare and a rabbit? At first sight, both look confusingly alike for both have long ears and a stumpy tail.

They are slow, really slow ... they are soft, they are slimy ...and greedy.
Learn moreMammals I
When we talk about animals in everyday conversation, we mostly talk about mammals. Mammals live in water, on land and in the air. Countless species of the most diverse sizes and appearances populate our earth. A clear classification is not always possible because of their adaptation to their different habitats.
Learn moreThe Honey Bee
Untiringly, the honey bees fly from flower to flower, constantly in search of pollen and sweet nectar. These busy workers live together in a complex social system an insight into which is provided by this film. In vivid pictures, it describes the life of the honey bee in the bee colony and deals with the inhabi- tants of the beehive and their strict division of labour. It shows the worker bees foraging for food and communicating with each other in their characteristic way. The second part of the film illustrates how a new bee colony is formed and describes the course of a bee‘s year from the new queen to the mating flight and the brood cells and finally to the expulsion of the drones in the „slaughter of the drones“. The DVD and the didactically arranged worksheets are per- fectly suited for the classroom both as an introduction to the topic and as a tool for the pupils when working individually or preparing projects.
Learn moreBats
Bats are the only mammals that can fly actively. In mythology they represent the dark element and were the inspiration behind the invention of vampire stories. On account of their nocturnal way of life and their dark appearance, they are considered scary by many people. But the nocturnal hunters are by no means keen on human blood. They mainly hunt insects, thus assuming an important role as natural pest controllers.
Learn moreHunters and Hunted
The African night is not for sleeping. A lot is going on there. The hunters are lying in ambush and the preys are on alert. Predators are mammals. Scientifically they are called carnivores. But other predatory vertebrates such as cats, jackals, hyenas and crocodiles are colloquially termed »predators«. They feed on meat but are not very selective in doing so. As they are not specialised in one type of animal but eat all vertebrates as well as carrion, they are called opportunistic feeders, which means they target the food that is easiest for them to catch, in the shortest time and with minimum energy input.
