Aluminium II
The metal aluminium is growing in importance because of its specific properties and manifold application possibilities. This DVD deals with the industrial production of aluminium as a raw material, its processing and the manufacturing of alloys for the finished product. Starting with the raw material aluminium oxide the functioning of an electrolytic cell is demonstrated and explained. Alumina, white and powdery, is melted with great expenditure of energy, and by means of electrolysis converted into aluminium with a degree of purity of 99.9%. As aluminium oxide would not melt before a temperature of over 2,000°C is reached, the mineral cryolite is used as a solvent. The various alloys change the properties of aluminium and are produced according to precise formulations. The alloy is cast into blocks and bars that serve as primary material for processing plants. The responsible handling of resources underscores the importance of recycling. Aluminium is resilient and versatile.
Fire and Flame
Fire – one of the most important human discoveries. It gives us warmth and light, conveys security and fascinates us with its dancing flames.
Carbohydrates
The term carbohydrate or saccharide is a collective name for all substances with the chemical formula Cn(H2O)n. Carbohydrates are the basis of nutrition. They are part of our diet as starch, glucose (grape sugar), fructose (fruit sugar), lactose (milk sugar) and saccharose (beet, cane or table sugar). Important suppliers of carbohydrates are potatoes and cereals such as rice, wheat, maize, millet, rye and oats. The various carbohydrates in our foods are introduced to the pupils. The characteristics of polysaccharides, disaccharides and monosaccharides are explained to them and in which foods these substances occur and how they are structured. In addition, the different origins of starch, starch degradation products, gelling agents as well as sugar alcohols in confectionery are dealt with. The DVD shows how various substances can be detected with the help of chemical processes. Together with the extensive accompanying material the DVD is ideally suited for use in the classroom.
