Vertebrates
Development and Diversity
This DVD introduces the members of vertebrates group existing today, illustrated by various examples. The phyloge- netic development, which started in the primeval oceans, is shown in detail by means of homologous skeleton structures. The variations in the body’s basic structure in adaptation to the vertebrates’ respective needs, which resulted in today’s situation with vertebrates living in water, on land and in the air, are demonstrated by means of extant representatives of the class. The vertebrates group encompasses cartilage and bony fishes, amphibians, reptiles, birds and mammals. The modifications of those skeletal elements serving locomotion, from the fins of the fish to the wing span of the birds and the hands of mammals, are shown. This DVD is suitable for the topic of vertebrates for younger pupils or as a contribution to the topic of evolution illustrated by means of the development of vertebrates.

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.
