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

Energy-saving lamps are energy-efficient illuminants which will step by step replace energy-intensive illuminants. This replacement has been laid down in an EU framework directive. This directive has resulted in two laws, according to which, for example, conventional light bulbs are to be replaced by energy-efficient lamps such as compact fluorescent or halogen lamps.

Learn moreBasics 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.
