Produkte des Alltags
Gut verpackt ist halb verkauft. Je kreativer, bunter und ansprechender Produkte verpackt sind, desto besser lassen sie sich verkaufen. Laut aktuellen Studien trifft ein Käufer seine Entscheidung in nur 1,6 Sekunden. Und dabei lässt er sich meistens von Größe, Farbe, Design und dem Namen des Produkts leiten. Der Inhalt wird bei der Kaufentscheidung oft zur Nebensache. In dieser neuen Folge von "Schau Dich schlau!" erklären Joey Grit Winkler und Fero Andersen neben psychologisch präzise ausgefeilten Verkaufsstrategien auch die Herkunft der bekanntesten Markennamen. Psychologen haben herausgefunden: Sehen wir etwas Rotes, Gelbes oder Orangenes, bekommen wir automatisch Appetit. Fällt unser Blick auf etwas Grünes oder Blaues, denken wir an Sauberkeit und Frische. Von einem Experten wird Joey Grit Winkler in die Geheimnisse der Verpackungswelt eingeführt und lässt sich erklären, woher die bekanntesten Markennamen kommen. Währenddessen taucht Fero Andersen in die Materie ein und analysiert, ob in den Verpackungen auch immer das drin steckt, was drauf steht. Muss Schwarzwälder Schinken aus dem Schwarzwald stammen? Oder genügt es, wenn der Schinken lediglich im Schwarzwald geräuchert wurde, das Fleisch aber aus Dänemark stammt? "Schau Dich schlau!" klärt über diese und andere wichtige und interessante Verbraucherfragen auf.

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.

Aluminium I
In the modern world, we encounter aluminium at every turn. This is due to the particular properties of the metal. Increasingly, aluminium is about to edge iron and steel out of engineering, as aluminium allows energy-saving lightweight construction of aircraft and vehicles of all kind. Aluminium is weather-resistant, does not rust and is therefore well suited as building material for house facades, window frames or simply for all parts that are exposed to wind and weather. At the same time, aluminium has a noble-looking surface recommending it as material for interior design.

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.

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.

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.

Solutions, Emulsions and Mixtures of Substances
Be it milk in a cereal bowl, tea in a glass or the air around us. We constantly come across mixtures of substances in our everyday lives. As the name suggests, they are mixtures – mixtures of several so-called pure substances.

Noble Gases
Xenon, Helium, Neon, Argon, Krypton and the radioactive Radon belong to the noble gases. These form the family of noble gases as the elements of the eighth group of the periodic table. All of them are colourless and odourless, non-inflammable and non-toxic. Their most striking chemical property is their inertness. This can be explained by their electron arrangement, termed noble gas configuration and represents a particularly stable and therefore low-energy state. The noble gases are to be found in scant amounts in our air from which they are also distilled. Helium is mainly extracted from natural gas. In everyday life, we encounter noble gases for example as shielding, filling or buoyant gases and in fluorescent tubes. The shell model describes the structure of the atoms. It is based on the distribution of electrons in restricted areas at a fixed distance around the core of the atom.

Periodic Table
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.

Fascination Lime
Many products used in everyday life are impossible without lime. These are, among others, glass, sugar, paper as well as pharmaceutical and cosmetic products. The raw material is also indispensable in the construction materials industry. Iron and steel producers need limestone, in environmental protection it is used, for example, for air cleaning and drinking water purification.
