Baden-Wuerttemberg
Baden-Wuerttemberg – The Federal States Baden-Wuerttemberg, the third largest federal state, is located in the southwest of Germany. Its landscape structure is highly diverse and offers such different nature areas as the Odenwald, the Spessart, the Upper Rhine Plain, the Black Forest and the Swabian Jura. Baden-Wuerttemberg, formerly divided into Baden and Wuerttemberg, has a long and turbulent history, which can be traced far back into the past. The federal state itself is not very old, it is the youngest federal state in Germany. Baden-Wuerttemberg counts among the economically strongest and most competitive regions of Europe. It is the exporting country number one among the federal states and is considered the most innovative region of the EU as far as high technology, research and development are concerned. Of particular interest for tourism are Baden-Wuerttemberg traditions, among them the typical Black Forest houses and the costumes with their ”Bollenhut“ hats. Together with the extensive additional material the DVD is ideally suited for use in the classroom.

Banana
Bananas can be bought at any supermarket today. We eat them raw or make them into cakes, shakes and ice-cream. But where do bananas come from? How have they got to the supermarket? On plantations in Costa Rica bananas are cultivated in an elaborate process. It is most important that bananas always have enough heat, sun and water. When the bananas are harvested, the workers carefully cut them off with machetes and take them to the packaging station. From there they are transported to the container ships by lorry. In the process the fruits undergo constant quality control. Storage temperature is important as well. After about three weeks the bananas are ready for sale at our supermarkets. The film illustrates the development of the banana from planting to harvest and the subsequent transport until they are finally sold at our supermarkets. Why does the banana not rot on the journey? Why is the banana bent? These and more questions are vividly answered. With the extensive accompanying material the didactic DVD is perfectly suited for use in the classroom

Basics of BIOLOGY I
Basics of Biology examines general biological issues that help to expand and consolidate basic biological knowledge. The first film of this series deals with the structure of the plant cell. It centres around the structure and function of plant tissue such as the xylem, root cells and stomata as well as the functions of the chloroplasts. In the second chapter the issue of photosynthesis and the elements involved in it are dealt with. With tests and experiments impacts of light and CO2 on photosynthesis are demonstrated and explained. The third part explains human respiration. The rising oxygen consumption of a woman athlete brought on by physical effort on the moving walkway is shown. What happens when the physical stress becomes too strong and the amount of oxygen inhaled is no longer sufficient? The transition from aerobic respiration to anaerobic respiration is vividly illustrated. Together with the extensive accompanying material the didactic DVD is ideally suited for use in the classroom.

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.

Basics of Biology III
What is the importance and function of enzymes? The lock-and-key principle is explained and, based on amylase and katalase, the dependence of reaction speed and intensity of effect on temperature and pH-value can be seen. With microscopic pictures and graphs the structure of animal cells is explained. But their appearance is very different depending on their functions. Nerve cells differ from blood cells just like the latter from sperm cells. A tissue is a combination of many cells that perform specific functions in the body. Any kind of growth of an organism is only possible when new cells are created. The process of cell division is called mitosis. This is then differentiated from the multiplication of reproductive cells, as in them the number of chromosomes must be reduced to half. Impressive shots and graphs illustrate these processes. Together with the extensive accompanying material the DVD is ideally suited for use in the classroom.

Basics of Chemistry I
We are surrounded by objects and substances. We recognise objects that are to serve a specific purpose by their shapes. Similar objects may consist of different materials or substances. Substances, however, are independent of shapes and possess very specific properties. We are able to perceive many of these substances with our senses. For example, we can see, touch or smell them so as to be able to recognise them. Chemists are particularly interested in those substance characteristics that can be measured. On the basis of these measurable properties they can distinguish between substances, identify a specific substance or test it for special use. Models help us to understand phenomena. They depict only specific elements of our reality, thus presenting the world in a simplified way. The spherical particle model, for example, helps us to understand how a scent spreads all over the room or substances disperse in water.

Basics of Chemistry II
When we take a closer look at substances, we discover that they consist of either one single element or of mixtures of several elements. Chemists therefore divide the world of substances into pure and mixed chemical substances. A pure substance is of homogeneous composition. Substance mixtures, however, consist of two or more pure substances. The many mixtures are subdivided not only into homogeneous and heterogeneous mixtures but depending on the respective aggregate states of their components, are classified into various groups of mixtures.

Bats
Bats are the only mammals that can fly actively. In mythology they represent the dark element and were the inspiration behind the invention of vampire stories. On account of their nocturnal way of life and their dark appearance, they are considered scary by many people. But the nocturnal hunters are by no means keen on human blood. They mainly hunt insects, thus assuming an important role as natural pest controllers.
