Marine Mammals
The oceans are the home of whales, which look like fish but, in fact, are mammals like we humans and breathe with their lungs. The film shows the peculiarities of whales, which are divided into two main groups: baleen whales and toothed whales. Baleen whales, among which there is also the blue whale, the biggest of all whales, feed on tiny crustaceans called krill. Toothed whales feed on fish, crabs and other marine animals. One of the best known representatives is the killer whale, which is the fastest marine mammal with a speed of up to 55 km/h. With their leaps they delight the audiences in sea life aquariums. Whether they should be kept like that is a highly controversial issue, however. Whales are also much coveted because of their fat, meat and oil. Having been ruthlessly killed, whales have amost been wiped out and today are subject to international protection. Whale watching boosts people’s interest in these formidable animals. Another threatened animal species lives in the warm and shallow waters of Central America: the sea cows, which feed exclusively on plants and surface for breathing every 2 to 5 minutes. With the extensive accompanying material this DVD is perfectly suited for use in the classroom.

They are many children’s favourites. And expert gymnasts in their realm. Dexterously they make their way hand over hand from branch to branch or skilfully climb the long ropes. And in many respects they are quite similar to us – the monkeys, in particular the great apes. These here live in a zoo. But – where, actually, is their true homeland? Apes such as the orangutans, gorillas, chimpanzees and bonobos originate from the tropical rainforests.

Learn moreWind Energy
Our future lies in renewable energies. The fossil fuels coal, oil and gas will be used up within the next 50 to 300 years and are ecologically questionable just like nuclear energy, too. The sun, however, provides more energy than we need. Besides water power, sun light and bio mass, WIND ENERGY, most crucially, belongs to the renewable energies that have been used already for centuries. But what is wind? How was its energy generated, transformed and used in the past and how is this done today?

Learn moreWays to Democracy
This film shows the most important stages on the way to the development of democracy in Germany. It begins with the foundation (1792) and quick end (1793) of the Republic of Mainz in the course of the French Revolution, gives an account of the Hambacher Fest in the pre-March era and the failed revolution of 1848/49, contemplates the democratic development in the German empire and the late realisation of the first German democratic national state in the Republic of Weimar. Other important steps are the erosion of the Weimar constitution after 1933, Germany’s transformation into the national socialist dictatorship and World War II as well as the formation of different democratic models in West Germany and East Germany after 1945. Finally, it is described where the rules of democracy can be explained and practiced today and what current dangers there are to the democratic system of government. The aim is to make pupils aware of the fact that democracy must not be taken for granted – it is a historical legacy that we always have to safeguard.
