Basics of BIOLOGY I
Basics of Biology examines general biological issues that help to expand and consolidate basic biological knowledge. The first film of this series deals with the structure of the plant cell. It centres around the structure and function of plant tissue such as the xylem, root cells and stomata as well as the functions of the chloroplasts. In the second chapter the issue of photosynthesis and the elements involved in it are dealt with. With tests and experiments impacts of light and CO2 on photosynthesis are demonstrated and explained. The third part explains human respiration. The rising oxygen consumption of a woman athlete brought on by physical effort on the moving walkway is shown. What happens when the physical stress becomes too strong and the amount of oxygen inhaled is no longer sufficient? The transition from aerobic respiration to anaerobic respiration is vividly illustrated. Together with the extensive accompanying material the didactic DVD is ideally suited for use in the classroom.

New Species in our Environment
More and more animal and plant species successfully spread far away from their original homes. They are organisms that with our assistance – or even alone – are disseminated further and further across the globe: they are called invasive species.

Bavaria
The free state of Bavaria is one of the most diverse states of the Federal Republic of Germany. Amidst the Alps with the Alpine Foothills and the Frankenwald and Lake Constance in the southwest, there are various regions that considerably differ from each other with regard to landscape as well as to economic basis. From a historical point of view, too, today’s Bavaria has evolved from individual states like the Duchy of Bavaria and several dioceses and free imperial cities like, for instance, Freising and Augsburg. Particularly interesting is the rise of the former agrarian state, which was to a large extent structurally weak, to one of the leading federal states in terms of economy and technology in the period from World War II until today. With its culture and numerous cultural treasures, Bavaria attracts tourists from all over the world, which contri- buted to the emergence of a service-oriented economy. Due to the modified, modular regional-studies approach, the DVD is suitable from the 5th to the 10th year of school.

Wine-Growing
The film starts with a short, simple overview of the importance of viticulture in Germany and Austria and the most famous wine regions in both countries. Then it goes on to discuss the most important conditions (soil, solar radiation) and forms of cultivation (terraces and vineyards on the plains) as well as the most widely spread types of grapes in Germany and Austria. In the main part of the film, pupils of a primary school accompany a wine-grower throughout the working year, watching him at work in the vineyard: form of the vine, work in winter (pruning, fruitbearing vines, substitute vines) turning cut-off vines into chaff, additional jobs (hammering in sticks, tightening wires, fastening fruit-bearing vines), removal of the earth from the grafting spots, pest control, cultivation of green manure crops, removal of surplus shoots, blossoming, weed removal, fighting nematodes (threadworms) biologically by cultivating daikon radish and, finally, harvesting. Apart from the manual harvest – where young and old people join in – also the use of harvesters is described.
