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.

Vivid pictures illustrate the difference between low hedges, hedges of middle height and high hedges. The structure of the hedge is explained in detail. The DVD shows the hedge in the course of a year with the accompanying changes in flora and fauna. Here, an emphasis is put on introducing the most common shrubs, trees, flowers and animal species associated with the biotope of a hedge.In addition, the pupils learn to distinguish between poisonous and edible fruit from indigenous shrubs, illustrated by the examples of elder bush, blackthorn and the spindle tree. Blooms, fruit, spiders, insects and other hedge-dwellers are presented in close-ups of superior quality. The learning target “from the bloom to the fruit” is illustrated with the help of an animation.
