X-Radiation
Discovery, Properties and Applications
They are enormously rich in energy and easily penetrate the body but in spite of this, we can neither see nor feel them: X-rays work in secret.
Because of their physical properties we owe important advances in medicine to them. Their ability to see through the body and make bone and tissue structures visible allows us to diagnose fractures or diseases without opening the body.
X-rays, artificially generated in an X-ray tube, are ionising like radioactive radiation and can impair the functions of body cells.
Therefore, the use of X-rays is subject to strict regulations because benefits and possible harmful effects, above all of X-ray examinations and radiotherapy, must be carefully weighed up.

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.
