Aberglaube
Glücksbringer, Geister, Horoskope – Fast jeder dritte Europäer ist in irgendeiner Weise abergläubisch. Doch was fällt eigentlich alles unter Aberglaube? Und ist jeder Aberglaube tatsächlich Hokuspokus? Manch eine Bauernregel kann z.B. mit einer meteorologischen Wettervorhersage standhalten. Die psychologische Wirkung von Glücksbringern ist auch nicht zu unterschätzen. Ob diese jedoch einem objektiven Test standhalten, ist fraglich. Dubiose Wahrsager bieten mittlerweile nicht mehr nur auf Jahrmärkten ihre Künste an, wobei sie allein mit einer geschickten Fragetechnik den Kunden auf Glatteis führen können.

Human Liver
Normally you do not feel it, it does not beat like the heart, neither can we feel it like the lungs when we breathe in and out – nevertheless, it is one of our most important organs: the liver.

The Honey Bee
Untiringly, the honey bees fly from flower to flower, constantly in search of pollen and sweet nectar. These busy workers live together in a complex social system an insight into which is provided by this film. In vivid pictures, it describes the life of the honey bee in the bee colony and deals with the inhabi- tants of the beehive and their strict division of labour. It shows the worker bees foraging for food and communicating with each other in their characteristic way. The second part of the film illustrates how a new bee colony is formed and describes the course of a bee‘s year from the new queen to the mating flight and the brood cells and finally to the expulsion of the drones in the „slaughter of the drones“. The DVD and the didactically arranged worksheets are per- fectly suited for the classroom both as an introduction to the topic and as a tool for the pupils when working individually or preparing projects.

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.
