Halogens
The compounds of halogens are - with the exception of astatine - widespread, can be encountered in nature and are versatile substances. This fact is taken up on this DVD in order to teach the students the chemistry of the halogens by illustrating their special qualities and explaining the correlation of their structure with their chemical properties. In the first part, an overview of the element group of halogens lays emphasis on the common as well as on the distinguishing characteristics of fluorine, chlorine, bromine and iodine. In a second part, the specific properties of bromine and iodine are presented. This topic is linked to the students‘ everyday experience on the one hand (bromine as a catalyst for reactolite sunglasses, iodine as an agent in medicine, etc.) on the one hand. As a rule, they are of a kind that can only be realized with difficulty, or high expenditure in the chemistry classroom. With the help of these experiments, students are introduced to the chemistry of the halogens in a way that enables them to draw conclusions on the basis of their observations.

This topic is linked to the students‘ everyday experience (fluorine as a protection against caries, chlorine as a disinfectant, etc.) on the one hand. On the other hand, the DVD presents carefully selected experiments. As a rule, they are of a kind that can only be realized with difficulty, or high expenditure in the chemistry classroom. With the help of these experiments, students are introduced to the chemistry of the halogens in a way that enables them to draw conclusions on the basis of their observations.

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.

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.
