Mammals 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.

Ticks
Already the dinosaurs, which populated the Earth some 90 million years ago, were familiar with the tiny, dangerous pests, and the Greek poet Homer attributed healing and potency-enhancing effects to them in the late 8th century BC – however, only in pulverised form. The animals described are those clingy, blood-sucking mini-vampires – the ticks. In fact, they are parasites dangerous to us humans; not because of the amount of blood they extract but due to the diseases they can transmit in doing so. This film invites you to visit the family of the small parasites of the phylum Athropoda belonging to the class of Arachnida.

Migratory Birds
Wenn Vogelarten die Jahreszeiten an unterschiedlichen Orten verbringen, werden sie als Zugvögel bezeichnet. Mehrere Milliarden von ihnen sind jährlich unterwegs. Alljährlich machen sie sich von ihren Brutplätzen auf den Weg in ihr Winterquartier und zurück. Dabei fliegen manche Arten Tausende Kilometer. Sie überqueren Gebirge, Ozeane und Kontinente. Es ist eine Reise voller Hindernisse und Gefahren. Wie finden Zugvögel punktgenau ihr Ziel? Sie haben mehrere Möglichkeiten: Mit ihrem inneren Kompass können sie das Erdmagnetfeld wahrnehmen. Wie sie das genau machen, weiß man noch nicht. Sie können sich aber auch am Stand der Sonne, der Sterne und anhand der Landschaften orientieren. Den Sonnenstand erkennen sie selbst bei bedecktem Himmel, da sie UV-Licht wahrnehmen. Durch Meeresbrandung entstehen tiefe, für uns unhörbare sogenannte Infraschalltöne. Auch danach können sich einige Vogelarten orientieren. Gemeinsam mit dem umfangreichen Unterrichts- und Begleitmaterial auf dem Datenteil der DVD ist der mehrsprachige Unterrichtsfilm bestens für den Einsatz im Unterricht geeignet.

Mass Coaching
It has long been generally recognised that the modern working world often pushes people to the limits of their stress resistance. In many professional fields and enterprises all work and efforts are dominated by the maxim: “success“. Cheerful, motivated, vigorous and full of youthful energy employees are to engage themselves in their companies or present themselves in job applications. But what happens when the success in life, the motivation and the joy of work fail to materialise fort the most various reasons?

Earthquakes
For millennia, people have been afraid of earthquakes. A force of nature that regularly devastates whole regions and claims thousands of lives. One reason for the fear of earthquakes may be that so far people have not succeeded in predicting these natural phenomena. Therefore, earthquakes still hit people unprepared in most regions of the world.

Alpine Glaciers
Melting alpine glaciers are the most conspicuous indication of global warming, and in the wake of the climate discussion, the public has become increasingly aware of their fate. Besides the structure and function of the glaciers, the film describes their role in the ecosystem and for the economically active human. In this respect, primarily the role of the glaciers for the water balance of the Alps and neighbouring regions and above all, their effects on summer and skiing tourism as well as the energy generation from water power are of major importance. The dwindling of the glaciers is illustrated with the help of historical comparisons. The Pasterze in Austria – the largest glacier of the eastern Alps – and the Bavarian Zugspitze are given as detailed examples. The film addresses younger pupils in the context of the topic of the Alps as well as older secondary school students in the context of climate issues.

Sicherheitspolitik
Nach Ende des Zweiten Weltkriegs wuchsen rasch die Spannungen zwischen den beiden Weltmächten USA und UdSSR, die zur Schaffung der beiden Militärbündnisse NATO und Warschauer Pakt führten. Nach Ende des Kalten Krieges und der Auflösung des Warschauer Paktes veränderte sich die weltweite Sicherheitsarchitektur. Wie wichtig die NATO noch heute ist, zeigt die Bedrohung, die für Westeuropa nach dem russischen Einmarsch in der Ukraine entstanden ist.

The European Parliament
The European Union is a union consisting of 27 European states. Currently its population comprises about 500 million inhabitants. 17 of these states have a common currency. Its aim is a pan-European area of freedom, security and justice. The European Parliament is elected every five years by the EU citizens and is thus the only directly elected body. The European Parliament shares its legislative function with the Council of the European Union, wherein the governments of the individual member states are represented, and the European Commission, which represents the interests of the EU as a whole. These three institutions together develop the political strategies and legislative provisions which are applied throughout the EU. The European Parliament ensures uniform pan-European regulations. Citizens profit from them for example for data protection, for mobile tariffs, for working and living in Europe and much more besides! Together with the extensive accompanying material the DVD is ideally suited for use in the classroom.

The Otto Engine
This DVD offers an insight into the historical birth of the Otto engine and also describes its latest version – the hybrid engine. In addition, other engines of the future are covered. The life and achievements of Nikolaus August Otto are dis- cussed, with all his successes and failures, from his first en- gineering attempts when reconstructing the Lenoir engine to the presentation of the “atmospheric gas engine” on the Paris World Fair through to his cooperation with Gottlieb Daimler and Wilhelm Maybach. The mode of operation of the Otto engine is explained to the pupils in detail, also with the help of a variety of animations and diagrams. The DVD goes into the four strokes of intake, compression, power and exhaust as well as the Otto engine as energy converter. Crude oil is one of our most important sources of energy. Besides outlining the evolution and processing of crude oil into fuel, this DVD puts emphasis on the increasing shortage of global crude oil resources. Alternative propulsion sources like hybrid engines as well as hydrogen-fuelled or gas-fuelled vehicles offer an environmental-friendly vision for the automobile’s future in times of global climate change.

Solar Energy
80 % of our current energy needs are covered by fossil fuels (coal, oil, gas). Their supply may soon lead to severe problems as worldwide stocks will be exhausted one day. That is why the future belongs to renewable energy from sun, wind, water, and biomass. The Sun as an inexhaustible energy source is estimated to be available to us for another 4.5 billion years to come. It supplies us with “clean energy“ that is available everywhere on earth and that exceeds worldwide energy needs many times over. The film presents the pupils with the long history of solar energy use. The functioning of solar collectors, solar cells and solar power plants is explained, the current operating ranges of solar technology are dealt with and an outlook for the future is provided. With the act on the phasing-out of nuclear energy Germany has taken over a pioneering role worldwide in the field of renewable energies. Together with the extensive accompanying material the DVD is ideally suited for use in the classroom.
