Learn moreSharks
The enormous size of the jaws and the frightening teeth of sharks have always attracted people's interest. Horrifying news of attacks on humans did the rest – "Jaws“: Steven Spielberg turned this best seller by Peter Benchley into a world-famous film. The story, published in 1974, is based on true events. In the 1960s, sharks were often spotted off America's coasts and the press was generous with reports often so scary that fear was fuelled. One day, as a shark stranded, it was a unique opportunity for the crowd of perplexed swimmers to observe the supposedly terrible monster at close range. Watching living sharks from special protective cages is a popular albeit expensive tourist attraction. It is an unforgettable experience to watch and photograph a shark swimming freely and gliding gracefully.
Learn moreReptiles
This DVD offers a clearly structured overview over reptiles with an emphasis on the following aspects: The origin of reptiles is proven by fossil finds from all over the world. The skeletons are proof that reptiles were not confined to life on land but were also adapted to water and the air. The typical common characteristics of reptiles, such as the coat of scales and a poikilothermic body temperature, as well as the extremely different appearances of poisonous snakes and constrictors, turtles, lizards and crocodiles are discussed in detail. The different methods of finding food both as a herbivore or as an ambush predator with the use of poison or with the help of a pit organ are shown. The “invention” of the amnion made the reptiles’ reproduction independent from water and enab- led them to lay their eggs on land.
Learn moreThe Eurasian Eagle Owl
With a body length of 60 to 75 cm and a wingspan of up to 170 cm, the Eurasian eagle owl is the largest owl in the world. It is also referred to as “king of the night skies”. After being hunted and almost exterminated by humans, the population of the Eurasian eagle owl has started rising again since the middle of the 20th century. Nevertheless, according to experts, it is not secured yet. Destroyed habitats and disturbances at the breeding sites, for instance by climbers, as well as dangers from power poles still threaten the population of the Eurasian eagle owl today.

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 moreKirchen
Kirchen haben eine lange Tradition und von außen sind sie heute meistens gut erkennbar. Aber wie sehen Kirchen eigentlich von innen aus? Denn egal ob alt oder neu, groß oder klein ─ so unterschiedlich sie auch aussehen, die meisten Gegenstände findet man in jeder Kirche. Der erste Blick, wenn man eine Kirche betritt, fällt meist auf den Altar und auf das über ihm hängende Kreuz. Für die Hostien, die den Christen so wertvoll sind, gibt es in der Kirche einen ganz besonderen Platz ─ den Tabernakel. Im Tabernakel werden die geweihten Hostien nach dem Abendmahl aufbewahrt. In der Nähe des Tabernakels hängt das ewige Licht.
Learn moreSeltene Erden
Der technische Fortschritt versorgt die Menschheit zuverlässig mit innovativer Technologie. Dies hat die Nachfrage nach spezifischen Rohstoffen, etwa für Mikrochips, Rußpartikelfilter, und Dauermagneten sprunghaft steigen lassen. Metalle wie Lithium, Cer, Neodym und weitere gehören zu den sogenannten „Seltenen Erden“. Der Bedarf nach ihnen hat große geopolitische Auswirkungen, und hat zum Aufstieg Chinas, das den Großteil der Lagerstätten auf seinem Gebiet birgt, entscheidend beigetragen.

Lignite, or brown coal, is an important energy carrier for providing Germany with electric power. In 2017 some 23 % of the country’s electricity was still obtained from lignite. German mining activities are centred in the Rhenish lignite fields to the west of Cologne. In the new eastern states, lignite is mainly extracted in the mining areas of Central Germany and Lusatia.
