Hydrological Cycle

Water is the source of life because life on our Earth originated in, more precisely, under the water. Water is essential for animals, plants and for us humans. Without water survival is impossible. Pure water is transparent, it smells and tastes of nothing. But where does the water come from? Where does it flow? And what happens to the water we do not use?

Water

This DVD offers an insight into the correlation between life and water. In simple terms that are easily understandable to primary school pupils, the film outlines the significance of water for the lives of humans, animals and plants. The DVD covers the following aspects of the topic: Water is Everywhere (deposits and utilisation), Drinking Water (journey of the water, role of the waterworks, water consump- tion), Wastewater (water pollution, processes at a wastewater treatment plant, purification of wastewater), the Water Cycle in Nature (groundwater, evaporation, formation of clouds, rain, infiltration), States of Water (transition between the states, easy-to-perform experiments, occurrence in nature), Properties of Water (what water can do, percentage of water in animals and plants, water as nourishment). The film is divided into five menu items (chapters). Each chapter can be individually accessed and worked on.

Postal Service

The postal service as an organisation for the delivery of news and retail goods through letters, postcards, parcels and packages is considered a part of the pupils‘ life experience and thus dealt with at primary school. This film is meant to illustrate this important procedural part of the children‘s lives and to make it intelligible to them. It deals with the writing, addressing, stamping and sending of a letter, with the importance of stamps, with the letter box and its emptying and the journey of a letter or a package from the sender to the addressee. Both as an introduction to the topic and as a tool in the hands of the pupils when working individually or preparing projects, the DVD and the didactically arranged accompanying material are perfectly suited for the classroom. A short excursus on the history of the stamp and a glance behind the scenes of a letter centre as well as a sorting centre, which usually cannot be visited, complete this informative DVD on the postal service.

Marine Mammals

The oceans are the home of whales, which look like fish but, in fact, are mammals like we humans and breathe with their lungs. The film shows the peculiarities of whales, which are divided into two main groups: baleen whales and toothed whales. Baleen whales, among which there is also the blue whale, the biggest of all whales, feed on tiny crustaceans called krill. Toothed whales feed on fish, crabs and other marine animals. One of the best known representatives is the killer whale, which is the fastest marine mammal with a speed of up to 55 km/h. With their leaps they delight the audiences in sea life aquariums. Whether they should be kept like that is a highly controversial issue, however. Whales are also much coveted because of their fat, meat and oil. Having been ruthlessly killed, whales have amost been wiped out and today are subject to international protection. Whale watching boosts people’s interest in these formidable animals. Another threatened animal species lives in the warm and shallow waters of Central America: the sea cows, which feed exclusively on plants and surface for breathing every 2 to 5 minutes. With the extensive accompanying material this DVD is perfectly suited for use in the classroom.

Chimpanzees

They are many children’s favourites. And expert gymnasts in their realm. Dexterously they make their way hand over hand from branch to branch or skilfully climb the long ropes. And in many respects they are quite similar to us – the monkeys, in particular the great apes. These here live in a zoo. But – where, actually, is their true homeland? Apes such as the orangutans, gorillas, chimpanzees and bonobos originate from the tropical rainforests.

Wind Energy

Our future lies in renewable energies. The fossil fuels coal, oil and gas will be used up within the next 50 to 300 years and are ecologically questionable just like nuclear energy, too. The sun, however, provides more energy than we need. Besides water power, sun light and bio mass, WIND ENERGY, most crucially, belongs to the renewable energies that have been used already for centuries. But what is wind? How was its energy generated, transformed and used in the past and how is this done today?
