Polizei
Mit ihrer Körpergröße von 1,70 Metern würde Joeys Karriere als Polizistin nichts im Wege stehen. Denn um sich der Spezialausbildung in Kampfsport, Fahr- und Klettertraining sowie einer umfassenden Schießausbildung auf der Polizeischule unterziehen zu dürfen, muss man strenge Vorgaben erfüllen. Neben einer entsprechenden Körperlänge, sind das Gewicht sowie sportliche Fähigkeiten entscheidend. Wer die Aufnahmeprüfung übersteht – in Deutschland sind das jährlich ca. 1.500 Männer und Frauen – durchläuft eine drei Jahre lang harte Schule mit einem einzigen Ziel vor Augen: die grüne Uniform! Doch neuerdings geht der Trend zu blau. Hamburg macht es vor und schickt seine Gesetzeshüter statt in waldgrün in enzianblau auf den Kiez. Doch die Hansestadt ist auch in einer anderen Disziplin ganz weit vorne: Im Verteilen von „Knöllchen“. Ob Falschparken, Temposünden oder Ruhestörungen, den Hamburger Polizisten entgeht fast nichts. Aber was kostet es, wenn man am Steuer zu viel Promille im Blut hat, einen Beamten beleidigt oder bei rot über die Ampel geht? Die Antwort darauf findet man im so genannten Bußgeldkatalog. Muss man diesen zu häufig konsultieren oder macht man sich anderer Vergehen schuldig, droht dem Delinquenten irgendwann der Gang ins Gericht.

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.

Evolution
Of all mammals existing today, the primates have the oldest phylogenetic tree. This film shows on the basis of extant species of the order of primates, which we humans also belong to, the phylogenetic tendencies in evolution from the treeshrew to prosimians, monkeys and apes to the genus homo. Special emphasis is laid on the visible outward characteristics of the skull and its sense organs, changes in the position of the spinal column as well as the development of extremities and their adaptation to various habitats. Changes in the anatomy of the skull, the development of the eye socket and also the shifting of the eyes from the sides to the front position, the dental structure and development of the jaw bones and the changing proportions of the mandible skeleton and the brain case are demonstrated on genuine skulls. The film analyses in detail the evolutionary tendencies of primates and convincingly answers the question on the origins of their development.

Ecosystem Lake
Lakes are stagnant waters that look quite peaceful to us. But the quiet is deceptive: above and below the water surface, life is anything but peaceful. Phytoplankton and zooplankton are eaten by small predators such as polyps or hydrachnidiae. Toebiters, dragonfly and beetle larvae are food for the water scorpion. As every animal feeds on different prey and in turn is eaten by various predators, a food web is created. The amount and variety of the lake inhabitants depends on the concentration of nutrients. In clear lakes, aquatic plants may spread down to a depth of 10 metres. Different zones with particular plant species are clearly visible. Also animals above the water profit from the rich underwater life, for example the waterfowl. Ever since the lake was formed, wind and waves have been carrying dead plants and animals to the shore, where they have sunk down and decomposed. At the same speed at which the lakeside grows, the water surface of the lake shrinks. With its extensive additional material the didactic DVD is ideally suited for use in the classroom.

Blood
One moment of distraction and the damage is done: Tim has slipped and has scraped his knee. The wound begins to bleed. Back home, Tim is comforted by his mother and a plaster is put on the knee. Actually, this is not necessary any more because Tim’s body has already started to help itself by forming a scab on the wound. A skin injury makes it possible for germs and dirt to enter the body. To prevent this from happening our organism repels all foreign substances, beginning at the same time to close the wound. This is done with the help of blood clotting, which starts directly when blood gets into contact with the outside world for example.
