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. On the basis of these measurable properties they can distinguish between substances, identify a specific substance or test it for special use. Models help us to understand phenomena. They depict only specific elements of our reality, thus presenting the world in a simplified way. The spherical particle model, for example, helps us to understand how a scent spreads all over the room or substances disperse in water.

Podcasting
Today, the use of new media has become a matter of course not only in everyday life – schools and teaching, too, benefit from the new technologies and methods, which support active and independent learning. Especially in computer science, ethics and language courses but also in all other subjects, modern media are a valuable pedagogic and didactic asset. This DVD uses the example of podcasts to demonstrate how the possibilities opened up by new media can be applied in the classroom and how the pupils can be taught to handle them in a competent and target-oriented manner. The film is aimed at supporting the use of podcasts at school and encourages making them. This also requires the ability to find information on the Internet and assess it. The film informs on the functionality of podcasts and technical background as well as on the teaching and learning possibilities offered by podcasts – ranging from specific contents to superordinate learning targets such as the advancement of creativity and team spirit. The DVD is a useful support for teachers applying new media and wishing to show their pupils how to handle Running Time: 20:29 ms them in a sensible way.
