Chemicals in the Home
Properties, Functions, Labelling
Baking, washing up, cleaning, – quite ordinary activities in the household. For these purposes we mostly use various aids such as baking and cleaning agents. However, we are often not aware of the chemical reactions involved.

Solutions, Emulsions and Mixtures of Substances
Properties and Uses
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.

Periodic Table
System of the Elements
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.

Alkali Metals
Properties, Examples, Relationship
What do lithium batteries, table salt and firework rockets have in common? All of them contain compounds of alkali metals. Alkali metals are members of the first group of the periodic table of the elements. The metals in this group are lithium, sodium, potassium, rubidium, caesium and francium.

Halogens
The Chemistry of Fluorine and Chlorine
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.

Acids and Bases
In Everyday Products
We can find acids and bases in every supermarket, some of them in our food, others in cleaning agents. In everyday products, acids and bases as well as acidic and alkaline reacting salts have extremely different functions.

Basics of Chemistry II
Mixing and Separating Substances
When we take a closer look at substances, we discover that they consist of either one single element or of mixtures of several elements. Chemists therefore divide the world of substances into pure and mixed chemical substances.

Basics of Chemistry I
Examining and Measuring Substances
We are surrounded by objects and substances. We recognise objects that are to serve a specific purpose by their shapes. Similar objects may consist of different materials or substances. Substances, however, are independent of shapes and possess very specific properties. We are able to perceive many of these substances with our senses. For example, we can see, touch or smell them so as to be able to recognise them. Chemists are particularly interested in those substance characteristics that can be measured.

Aluminium II
Production, Processing, Recycling
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

Aluminium I
Properties, Reactions, Specifics
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.

C, CO2 and Associates in Everyday Life
From Carbon to Car
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.

Carbohydrates
Chemistry as Sweet as Sugar
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).

Noble Gases
A Family of Noble Disposition
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.
