Fish 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.

A girl paints her idea of heaven. Angels welcome the dead people to paradise. There, near to Jesus, you can live and play. You also meet deceased relatives again.
Learn moreFloods
Most of our earth is covered in water. Without water, no life. The water on our earth is in a constantly renewed global cycle. By evaporation the water gets into the atmosphere, by atmospheric circulation the evaporated water is further transported across long distances and returns to the earth as precipitation. Climate change, however, alters this hydrological cycle. Climate change intensifies the disparities in the global water supply and increasingly causes droughts and floods, respectively.

“To be brought back down to earth” is an expression we use when someone needs to come back to reality. Just like the air to breathe, the soil is taken for granted and simply there – we do not need to think about it. However, it is an extremely complex, sensitive structure and not only the crucial production factor for farmers but their basis of their existence. Ultimately, the soil is the vital basis of life for plants and, directly or indirectly, for animals as well as us humans. Starting from the relevance of the soil, the film clarifies the diverse, mutual relations with other elements of the landscape. In this cinematic exploration, the manifold, soil-forming factors and processes such as, for instance, decomposition and humus formation are explained just like the geographical basic terms “soil profile”, “horizons” and “soil type”. Over the past 150 years approximately, a profound change has taken place in agricultural production, which was essential to provide a stable, high-quality sustenance of the growing population in the industrial states. The DVD also shows that heedless human interference into the soil ecosystem has brought about irreparable consequences.

Learn moreButcher
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.
Learn moreArtificial 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.

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.
Learn moreGreat 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.
Learn moreCarbohydrates
The term carbohydrate or saccharide is a collective name for all substances with the chemical formula Cn(H2O)n. Carbohydrates are the basis of nutrition. They are part of our diet as starch, glucose (grape sugar), fructose (fruit sugar), lactose (milk sugar) and saccharose (beet, cane or table sugar). Important suppliers of carbohydrates are potatoes and cereals such as rice, wheat, maize, millet, rye and oats. The various carbohydrates in our foods are introduced to the pupils. The characteristics of polysaccharides, disaccharides and monosaccharides are explained to them and in which foods these substances occur and how they are structured. In addition, the different origins of starch, starch degradation products, gelling agents as well as sugar alcohols in confectionery are dealt with. The DVD shows how various substances can be detected with the help of chemical processes. Together with the extensive accompanying material the DVD is ideally suited for use in the classroom.
