Basics of Biology III
Enzymes and Animal Cells
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.

Product Piracy
Counterfeiting takes place in almost all economic sectors – textiles, watches, car parts, machine parts, tools, accessories, software and medicines. Some counterfeits are easy to recognise, others are so well-executed that even experts have difficulty distinguishing between original and imitation. This DVD covers the development of a product from idea to manufacture. Once a product has become a trademark, product pirates appear on the scene.
Peer Mediation
Lena and Max attend the 7th form. Max is new in class. During a break, Max notices that Lena and her friend are laughing at him again. Max loses his temper! He slaps Lena in the face. That hurts and Lena runs back into the classroom with a red cheek. The growing conflict between the two has escalated. Just like Lena and Max, every day pupils all over Germany have rows with each other. At the Heinrich Hertz Gymnasium in Thuringia, pupils have been trained as mediators for years. At set hours, they are in a room made available by the school specifically for mediation purposes. The film describes the growing conflict between Max and Lena and shows a mediation using their example. In doing so, the terms “conflict” and “peer mediation” are explained in a non-technical way. The aims of peer mediation and its progress in five steps as well as the mediators’ tasks are illustrated. The art of asking questions and “mirroring”, which the mediators must know, is described and explained. Together with the comprehensive accompanying material, the DVD is a suitable medium to introduce peer mediation at your school, too.
