Earthworm
It is slippery, soft and slimy, burrows in the moist soil and many just find it disgusting – the earthworm. Most of us know it when it comes to the surface in heavy rain and ends in puddles or, possibly, as fish bait; but earthworms are true natural wonders and extremely useful. Only a very small percentage of all animals are vertebrates. These animals, such as mammals, birds, reptiles, amphibians and fish, all have a vertebral column. Over 90% of our fauna are invertebrate animals.
Learn moreFish
This DVD offers a clearly structured overview of fish with an emphasis on the following aspects: The typical body build of fish and their adaptation to the water habitat are shown. The fish skeleton proves that they are vertebrates. Their sense organs (eyes, nose, barbels, lateral lines) are adjusted for survival in water. The skin is characterised by different kinds of scales. Free water fish, ground fish and surface fish are distinguished from each other by three typical mouth and body shapes. Locomotion in the water is made possible by different kinds of fins. Respiration through gills is a typical feature of fish. Herbivores possess typical characteristics distinguishing them from carnivores. Swarm fish and loners display different behaviour patterns. The film is divided into six menu items (chapters), which may be individually accessed and worked on. For this purpose, additional pictures, diagrams, texts or selected short film clips are offered, which can simply be called up by remote control.
Learn moreThe White Stork
People have always found the white stork fascinating. It is a large, conspicuous bird, which exposes itself to human curiosity by the choice of its nesting places, therefore people tend to assign meaning to its behaviour. Today, the white stork is still believed to bring good luck. The film covers the characteristics of white storks, their appearance and behaviour as well as the order of Ciconiiformes. The habits of the white storks, their habitats and migration routes are shown in the film, too. In the Reproduction Chapter, we can see interesting pictures of hatching chicks and their first attempts at flying. The DVD includes first-grade bonus material on the bird migration research carried out by the Max Planck Research Centre for Ornithology headed by Peter Berthold. The white stork’s cultural significance and myths told about it as well as the ties between countries, which are strengthened by the “European Stork Villages”, are covered, too. The bonus material is only available in German and adds approximately 14 minutes to the film.
Learn moreBasics of Biology II
In its first chapter, Basics of Biology II deals with the food chain. The producers as the basis of the food chain and the consumers, the herbivores and carnivores, are introduced /presented. Further focus points are the energy intake through food as well as the energy losses connected with it. The resulting energy efficiency of a herbivore is vividly illustrated in an experiment. Subsequently the carbon cycle is dealt with: its occurrence and the carbon cycle from producer to consumer, and last but not least the function of destruents. In the third chapter the next important cycle, the nitrogen cycle, is discussed. Special emphasis is put on the process of nitrification as well as the function of nitrogen-binding micro-organisms and their natural fertilisation of our agricultural soil. The importance of the nitrate for plants is shown in a laboratory test. Together with the extensive additional material the DVD is ideally suited for use in the classroom.
Learn moreBiotechnology I
Biotechnology is the application of science and technology to living organisms. Today, biotechnology plays an increasingly important role in everyday life. Very rarely, however, are we aware of it because you cannot tell the biotechnological origin of products of the medical, pharmaceutical and food industries by their look. For example, the enzymes needed for cheese production are formed by biotechnologically programmed mould fungi.
Learn moreDachs
Der Dachs ist ein nachtaktiver Bewohner der heimischen Wälder. In teilweise jahrzehntealten, bis zu 5m tiefen Bauen verbringt er den Tag und begibt sich nachts auf Nahrungssuche.
Learn moreHuhn und Ei
Erstaunliche Zahlen im Zeitalter der Vogelgrippe: Über 18 Milliarden Eier werden jährlich in Deutschland verzehrt und über 10 Kilo Geflügelfleisch landen durchschnittlich im Magen eines jeden Bürgers. „Schau Dich schlau!“ widmet sich heute einer der leckersten Erfindungen der Natur: dem Ei und dem Huhn.
Learn moreEye
The eye is one of our most important sense organs. It provides direct access to the world.
Learn moreBiotechnology II
The results of the fundamental research in genetics and genetic engineering are the basis for the further development of biotechnology, whose basics have already been covered in part I of the biotechnology series. In conjunction with findings in microbiology, biotechnology has made significant progress. In particular the identification of the genetic code has opened up new possibilities for numerous applications. It has enabled the genetic modification of organisms for a desired purpose. The close cooperation between different disciplines in biotechnology continuously generates new insights and possible applications. Moreover, in the so-called red biotechnology – which is medical biotechnology – biologists, medical scientists and pharmacists contribute, amongst other things, to the development of new medicines, thus creating a link between scientific fundamental research and its medical application. An important example of red biotechnology is the production of insulin.
Learn moreVertebrates
This DVD introduces the members of vertebrates group existing today, illustrated by various examples. The phyloge- netic development, which started in the primeval oceans, is shown in detail by means of homologous skeleton structures. The variations in the body’s basic structure in adaptation to the vertebrates’ respective needs, which resulted in today’s situation with vertebrates living in water, on land and in the air, are demonstrated by means of extant representatives of the class. The vertebrates group encompasses cartilage and bony fishes, amphibians, reptiles, birds and mammals. The modifications of those skeletal elements serving locomotion, from the fins of the fish to the wing span of the birds and the hands of mammals, are shown. This DVD is suitable for the topic of vertebrates for younger pupils or as a contribution to the topic of evolution illustrated by means of the development of vertebrates.
Learn moreTicks
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.
