Basics 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.

Biotechnology 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.

Düngemittel
Pflanzen benötigen für ihr Wachstum, Licht, Wasser und Nährstoffe. Den Ausgleich für nicht vorhandene Nährstoffe schaffen Düngemittel. Doch welche Düngemittel gibt es? Welcher Dünger eignet sich für welchen Boden? Welche Konsequenzen bringt die Düngung mit sich?

Natur erleben
Die Naturwissenschaften gelangen zu ihren Ergebnissen durch präzise Beobachtung, durch fundierte Hypothesenbildung, deren experimentelle Überprüfung und Auswertung. Vermittelt werden die Ergebnisse in einem festgelegten Kanon der Darstellung, sei es durch Schaffung eines anschaulichen Modells oder einer detaillierten Zeichnung, sei es durch ein aussagekräftiges Diagramm.

Ducks
Ducks are our best-known water birds. You can watch them on almost any large body of water. Although we come across them frequently, most of us know very little about the lives of ducks. But it is worth our while to look at them more closely.

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.

Vertebrates
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.

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.

Mute Swan
Swans are an ornament to our waters. The majestic birds with their snow-white plumage are considered the very epitome of beauty and purity. Not every swan, however, is white. It is the Mute Swan that has inspired people’s imagination for ages. Seemingly an old acquaintance, it has nevertheless a great many unknown features for us to discover.

Vaccination
It is only in recent years that a vaccination has existed that is supposed to lower the risk of getting cervical cancer. This vaccination can protect against specific, sexually transmitted human papillomaviruses that are considered one of the causes for cervical cancer.

Lichtverschmutzung
Die Elektrifizierung bescherte der Menschheit einen technologischen Quantensprung. Insbesondere die Möglichkeit elektrischer Beleuchtung dehnte die Produktivitätszeiträume der Menschen aus. Dass künstliche Beleuchtung durchaus als „Lichtverschmutzung“ mit negativen Auswirkungen auf Menschen, Tiere und Pflanzen aufgefasst werden kann, ist eine vergleichsweise neue Erkenntnis.
