Earthquakes
Origin and Consequences
For millennia, people have been afraid of earthquakes. A force of nature that regularly devastates whole regions and claims thousands of lives. One reason for the fear of earthquakes may be that so far people have not succeeded in predicting these natural phenomena. Therefore, earthquakes still hit people unprepared in most regions of the world. No earthquake is like the other, they are distinguished by their duration as well as their strength. Based on measurements of so-called seismographs or seismometers at monitoring stations, earthquakes can be registered and ground motions recorded as so-called seismograms.

Magma
The face of our home planet is subjected to constant change. Mountains are created and eroded over time, oceans flood continental areas, glaciers assume gigantic proportions, modify landscapes and melt – all this happens mostly in very long geological periods of time. Far more spectacular and more comprehensible to humans in terms of time, however, are natural phenomena associated with magmatism, above all, when we encounter them in their most obvious manifestation, volcanism. These natural events that entail far-reaching changes on the surface of the earth, sometimes devastating destruction and high casualties, have impressed civilisations, inspired their imagination and often spread fear and terror from time immemorial. Let us look with wonder and awe at the following breath-taking pictures of volcanic eruptions. They spectacularly illustrate the huge, immeasurable forces hidden inside our earth. At the same time, these pictures make us aware how tiny and powerless we are ourselves.
Podcasting
Today, the use of new media has become a matter of course not only in everyday life – schools and teaching, too, benefit from the new technologies and methods, which support active and independent learning. Especially in computer science, ethics and language courses but also in all other subjects, modern media are a valuable pedagogic and didactic asset. This DVD uses the example of podcasts to demonstrate how the possibilities opened up by new media can be applied in the classroom and how the pupils can be taught to handle them in a competent and target-oriented manner. The film is aimed at supporting the use of podcasts at school and encourages making them. This also requires the ability to find information on the Internet and assess it. The film informs on the functionality of podcasts and technical background as well as on the teaching and learning possibilities offered by podcasts – ranging from specific contents to superordinate learning targets such as the advancement of creativity and team spirit. The DVD is a useful support for teachers applying new media and wishing to show their pupils how to handle Running Time: 20:29 ms them in a sensible way.
