Basics of Biology III
Enzymes and Animal Cells
What is the importance and function of enzymes? The lock-and-key principle is explained and, based on amylase and katalase, the dependence of reaction speed and intensity of effect on temperature and pH-value can be seen. With microscopic pictures and graphs the structure of animal cells is explained. But their appearance is very different depending on their functions. Nerve cells differ from blood cells just like the latter from sperm cells. A tissue is a combination of many cells that perform specific functions in the body. Any kind of growth of an organism is only possible when new cells are created. The process of cell division is called mitosis. This is then differentiated from the multiplication of reproductive cells, as in them the number of chromosomes must be reduced to half. Impressive shots and graphs illustrate these processes. Together with the extensive accompanying material the DVD is ideally suited for use in the classroom.

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.
The Daily Newspaper
Every day, there is a surge of news reaching us via different news channels. In spite of TV and Internet, the daily paper still is one of the most important main sources of news. But how is a newspaper created? The film shows the production of a paper in the course of one day. Starting with the editorial meeting in the morning, in which the topics and deadlines are determined, the film accompanies a journalist during her research work. You can see how a journalistic interview is conducted and what the photographer must consider when taking a press photo. Back in the editorial office, the editor’s work is illustrated, which includes the page layout and the writing of an online article in today’s time. Impressive pictures from the printing centre depict the process from the digital page to the finished newspaper. Together with the comprehensive accompanying material, the DVD is perfectly suited for use at school
Internet Addiction
The film consists of two parts. The first part is the 15-minute short film “In the Net”. It describes the problem of excessive Internet use in a humorous way, in particular the risk of losing touch with reality when chatting. The second part illustrates with three real persons how Internet addiction can develop and the problems encountered by those who are afflicted. The authentic statements are commented by an experienced therapist. For many pupils, the issues addressed here are related to their everyday lives. What is a “sensible” use of the Internet, where does pathological addiction start? In contrast to addiction to alcohol, nicotine or drugs, the public seems to be largely ignorant of the problem of this addiction, which is not related to any substance abuse. The film provides material for discussion in the classroom (crossdisciplinary) and can be used as a basis for the formulation of prevention strategies.
