The Otto Engine

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.

This DVD offers a clearly structured overview of the field of optics with an emphasis on the following main topics: All three models, i.e. the ray theory, the wave theory and the quantum theory of light, are explained by means of selected phenomena. The pupils learn about the conditions, the principles and appearances regarding reflection and refraction and are encouraged to perform easy experiments themselves. Optics are introduced to the pupils with the help of examples from nature, road traffic and the environment. Simple optical instruments such as a magnifying glass, a camera, a microscope, an astronomic telescope and the eye are described. Further, the visible part of the electromagnetic spectrum, a line spectrum, a solar cell and a radiometer are explained in selected sections. The film is divided into six menu items (chapters), which may be individually accessed and worked on. For this purpose, additional pictures, texts or selected short film clips are offered, which can simply be called up by remote control.

Gravity is the force that pulls something to the ground. It ensures that everything falls downwards. Like every force, it has a direction, namely towards the centre of the celestial body. The film vividly shows the development of the law of gravity from Isaac Newton through the further development by Albert Einstein, who described that gravity not only causes bodies to attract each other, but also causes space to curve around a body. Space and time are no longer absolute, fixed quantities, but changeable.

Photovoltaics is the direct conversion of light energy into electrical energy. This principle is increasingly being used as a regenerative energy source - for this purpose, large-scale solar collectors are being installed on house roofs and on open spaces.

Laws of Nature

Die Physik hilft uns zum Beispiel zu verstehen, warum Dinge fallen, wie sie fallen, wie Kräfte wirken und was sie bewirken. Warum manche Dinge schweben und andere nicht und wie wir mit diesem Wissen das Leben viel einfacher machen können.
