Amphibians
More than 350 million years ago, the evolution of amphibians set in. Amphibians developed from fish – a first step towards life on land. Diverse reproduction strategies, manifold forms of appearance and a broad spectrum of sizes, ranging from the tiny Brazil litter frog to the giant salamander, constitute the special characteristics of the class of amphibians. The pupils learn about the different respiration techniques and the particularities of the amphibians’ circulatory system as well as about their defining characteristics and their repro- duction strategies. Moreover, the threat to amphibian species posed by environ- mental poisons and the climate change is also discussed. This DVD leads the pupils into the fascinating, unknown world of amphibians, which still remains to be fully researched.

Hormones
Hormones influence our lives. Just like our nervous system, they transmit information in our bodies. When our hormonal balance is disrupted, our behaviour changes and we may fall ill. But what are hormones? Why have they got such a big influence? Where are they produced? And how do they work? The film leads us inside the human body – into the world of hormones. We learn that there are various hormones, where these are produced and how they work. We get acquainted with people whose lives have been influenced by a hormone deficiency or a hormone excess.

Blood
One moment of distraction and the damage is done: Tim has slipped and has scraped his knee. The wound begins to bleed. Back home, Tim is comforted by his mother and a plaster is put on the knee. Actually, this is not necessary any more because Tim’s body has already started to help itself by forming a scab on the wound. A skin injury makes it possible for germs and dirt to enter the body. To prevent this from happening our organism repels all foreign substances, beginning at the same time to close the wound. This is done with the help of blood clotting, which starts directly when blood gets into contact with the outside world for example.

Magma
The face of our home planet is subjected to constant change. Mountains are created and eroded over time, oceans flood continental areas, glaciers assume gigantic proportions, modify landscapes and melt – all this happens mostly in very long geological periods of time. Far more spectacular and more comprehensible to humans in terms of time, however, are natural phenomena associated with magmatism, above all, when we encounter them in their most obvious manifestation, volcanism. These natural events that entail far-reaching changes on the surface of the earth, sometimes devastating destruction and high casualties, have impressed civilisations, inspired their imagination and often spread fear and terror from time immemorial. Let us look with wonder and awe at the following breath-taking pictures of volcanic eruptions. They spectacularly illustrate the huge, immeasurable forces hidden inside our earth. At the same time, these pictures make us aware how tiny and powerless we are ourselves.

Major EU Project
The Brenner Base Tunnel and the New Brenner Railway are a project of the Trans-European Networks – in short, TEN. The aim is to connect European countries optimally and to contribute to a more environmental-friendly and efficient organisation of traffic. The transportation of cargo is to be shifted to the railway and public passenger transportation is to become more attractive. The TEN Axis No. 1 runs from Berlin to Palermo.

Butcher
Food is the basis of human life. Its diversity and quality are decisive for our health and well-being, thus also providing the basis for a good quality of life. It is a positive challenge to take on that kind of responsibility by choosing a career in this sector. A butcher’s job is such a challenge, not only with respect to the handling of the food itself but also with respect to the contact with customers. Butchers don’t just sell their products but also give advice to their customers and, in addition, the contact to business partners and public authorities is of considerable importance. Hence, this job is extremely versatile and never boring. Some on-the-job training in an internship provides the opportunity to get to know this profession better and to find out whether you are suitable for the job and whether you feel comfortable with your choice. It is important that a job opens up good career prospects for young people, thus building a bridge to an economically secure future.

Artificial Intelligence
Intelligent machines not only carry out predefined work steps but also learn from experience thus developing their own problem solving strategies. In addition, they can pass on their knowledge to other machines and interact with them. Artificial intelligence is pure software which, combined with various sensors, takes further decisions from the data thus obtained. Artificial intelligences have already conquered our everyday lives. When we have bought something online, an artificial intelligence could have ensured that we receive the ordered product on time. Because in many large companies machine brains help with logistics, accounting and customer service. Even at the doctor’s or in hospital we may come across artificial intelligence. Because sometimes it assists physicians with the diagnosis of diseases or in selecting an appropriate therapy. An AI can also be helpful in prognosticating the chances of recovery.

Ways 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.

Great Disasters I
A disaster occurs when the balance inherent in a certain phenomenon is disturbed. This can happen either because a new powerful force comes into play which triggers the disaster or because a small – even tiny – causal factor interferes in a situation with an unstable equilibrium and manages to achieve an enormous effect.
