Groundwater
When we open the tap, it gushes out: drinking water – clear and clean. It is our most important victual and can be replaced by NOTHING. On average every inhabitant of Germany consumes 125 litres every day! But where does our drinking water come from?

Hairdresser
Today regular appointments with the hairdresser are a matter of course for our individual styling. The aim is no longer to simply cut the hair so that it looks well-groomed but the hairdo is an expression of personality and thus intended to contribute to the overall look of a person. A good hairdresser knows about trends and lifestyle and what’s fashionable, and is able to give competent advice on how to complement the customers’ style. The job of a hairdresser is a positive challenge for everyone interested in fashion, lifestyle and creative work with other people. Apart from the technical knowledge and practical workmanship, primarily giving advice to customers as well as an understanding of the customers’ needs are key qualifications for this crisis-proof job. A traineeship is a possibility of getting familiar with a hairdresser’s work environment. An important aspect is that this career choice offers good prospects for young people on the job market, thus building a bridge to an economically secure future.

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 fluorine and chlorine are presented. 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.

Hands-on Biology
To perform the experiment with beans you need first of all the seeds, of course. Runner beans are well suited for it. Watch out! Eaten raw, bean seeds are poisonous! For the germination experiments you need one plant pot per experiment. You need a waterproof pen for labelling the pots. Moreover, a watering can and water are required to keep the plant soil moist which is also needed. Some of the plant soil should be dried beforehand. To exclude the light you need a carton, to exclude the air a solid, transparent plastic bag and to exclude the soil cotton wool. In addition, scales, a glass and a protractor are required.
