Periodic Table
System of the Elements
With the help of the periodic system chemists can predict properties of chemical elements and derive chemical reactions. But you need not be a chemist to understand the periodic system. First of all the question arises: What is a chemical element? Chemists of the past noted here: “A chemical element is a chemical substance that cannot be further broken down into other substances.“ All known substances are formed by these elements. At present (2017) we know 118 elements. The elements 113, 115, 117 and 118 were added most recently in 2016. They belong to the so far 27 elements which cannot be found in nature but are man-made. Many of the remaining 91 elements are found only in the form of chemical compounds in nature, not in their pure form.

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.
Blogging
The weblog or blog, for short, as a medium is not much older than this century. Blogs came into being in the World Wide Web as ’messages from below’, as web pages from web creators who wanted to share their view of the world with the world. They are short notes, long texts, pictures, videos, which are posted loosely and at random intervals to the world for an undefined public.
