Optics
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.

Wind Energy
Our future lies in renewable energies. The fossil fuels coal, oil and gas will be used up within the next 50 to 300 years and are ecologically questionable just like nuclear energy, too. The sun, however, provides more energy than we need. Besides water power, sun light and bio mass, WIND ENERGY, most crucially, belongs to the renewable energies that have been used already for centuries. But what is wind? How was its energy generated, transformed and used in the past and how is this done today?

Halogens
The compounds of halogens are - with the exception of astatine - widespread, can be encountered in nature and are versatile substances. This fact is taken up on this DVD in order to teach the students the chemistry of the halogens by illustrating their special qualities and explaining the correlation of their structure with their chemical properties. In the first part, an overview of the element group of halogens lays emphasis on the common as well as on the distinguishing characteristics of fluorine, chlorine, bromine and iodine. In a second part, the specific properties of fluorine and chlorine are presented. This topic is linked to the students‘ everyday experience (fluorine as a protection against caries, chlorine as a disinfectant, etc.) on the one hand. On the other hand, the DVD presents carefully selected experiments. As a rule, they are of a kind that can only be realized with difficulty, or high expenditure in the chemistry classroom. With the help of these experiments, students are introduced to the chemistry of the halogens in a way that enables them to draw conclusions on the basis of their observations.

The 14th Dalai Lama
He is considered one of the best-known personalities of our time and has been the Tibetans’ spiritual leader for more than 50 years. The Dalai Lama – His views are inspiration to many. The tradition of the Dalai Lamas reaches back to the 15th century. Dalai Lama is a Mongolian title of honour and was first bestowed on a Tibetan Buddhist monk in 1578 by the Mongol ruler at the time. This monk was called Gyatso, which means sea of wisdom. Dalai is the Mongolian translation of this name and lama is a Tibetan word for monk. Up to now the title has been conferred on 14 Tibetan monks, to the first two only posthumously.
