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.

Peer Mediation
Lena and Max attend the 7th form. Max is new in class. During a break, Max notices that Lena and her friend are laughing at him again. Max loses his temper! He slaps Lena in the face. That hurts and Lena runs back into the classroom with a red cheek. The growing conflict between the two has escalated. Just like Lena and Max, every day pupils all over Germany have rows with each other. At the Heinrich Hertz Gymnasium in Thuringia, pupils have been trained as mediators for years. At set hours, they are in a room made available by the school specifically for mediation purposes. The film describes the growing conflict between Max and Lena and shows a mediation using their example. In doing so, the terms “conflict” and “peer mediation” are explained in a non-technical way. The aims of peer mediation and its progress in five steps as well as the mediators’ tasks are illustrated. The art of asking questions and “mirroring”, which the mediators must know, is described and explained. Together with the comprehensive accompanying material, the DVD is a suitable medium to introduce peer mediation at your school, too.
