Plastic
Plastic has been around for not longer than roughly 100 years, and the synthetic material is a brilliant invention. Its production is cheap, it can take almost any possible form, it is light-weight, versatile and, above all, inexpensive.
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.
C, CO2 and Associates in Everyday Life
All organic matter contains carbon. Coal is deposited in the Earth's interior. It developed about 300 million years ago from plants in a geological period which is also called Carboniferous. During the combustion of organic matter, carbon turns into the gas carbon dioxide. Dissolved in water, it becomes the so-called carbonic acid. Carbon dioxide is an incombustible, colourless and odourless gas that is easily dissolved in water. With various metal oxides or hydroxides it forms two types of salts: the carbonates and the hydrogen carbonates. As calcium carbonate it is contained in natural products such as chalk and egg shells. Specific forms of carbon, called modifications, are graphite and also the particularly valuable diamond.
