The Otto Engine
Changing Times
This DVD offers an insight into the historical birth of the Otto engine and also describes its latest version – the hybrid engine. In addition, other engines of the future are covered. The life and achievements of Nikolaus August Otto are dis- cussed, with all his successes and failures, from his first en- gineering attempts when reconstructing the Lenoir engine to the presentation of the “atmospheric gas engine” on the Paris World Fair through to his cooperation with Gottlieb Daimler and Wilhelm Maybach. The mode of operation of the Otto engine is explained to the pupils in detail, also with the help of a variety of animations and diagrams. The DVD goes into the four strokes of intake, compression, power and exhaust as well as the Otto engine as energy converter. Crude oil is one of our most important sources of energy. Besides outlining the evolution and processing of crude oil into fuel, this DVD puts emphasis on the increasing shortage of global crude oil resources. Alternative propulsion sources like hybrid engines as well as hydrogen-fuelled or gas-fuelled vehicles offer an environmental-friendly vision for the automobile’s future in times of global climate change.

Computer Games
This film covers the topic of computer games in a variety of ways and from many different angles. Apart from the fascina- tion of computer games for users, the historical development as well as the production of computer games are described. The established genres are introduced, the guidelines of the German BPjM are explained. In light of recent public discussions, a neutral overview of the pros and cons of playing computer games is given, and different kinds of player behaviour are outlined. In this film, the pupils will recognise many aspects of their favourite pastime that encourage an independent, constructive use of this medium and reinforce their media competency. The film and teaching material are very closely related to the real-life situation.
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.
