Human Lung

Only rarely do we notice that we need them: our lungs. Mostly, we breathe unconsciously and shallowly – especially if we have a sitting job.

Horses

They are the epitome of power and elegance. Man domesticated them long after dog and cat, they provided meat, were strong agricultural helpers pulling ploughs and other implements. These hard times are over for the animals – their range of service has changed. The most favourite animal of many children and grown-ups, it has changed from former working animal to today’s companion for sport and leisure. The horse breeds known today are descended from a primeval horse. It lived about 50 million years ago – that is fifty with six zeros after it!

Contraception

In view of a considerable number of teenage pregnancies and commencement of sexual activities at an average age of 15, the topic of contraception is extremely important in lower secondary school. This DVD offers a complete film as well as working materi- al that allows for a discussion of the topic according to the requirements of the respective type of school as well as to the socio-cultural circumstances. Apart from the film itself, which outlines the most important contraceptive methods, selected animations can be accessed via the menu. They illustrate complex content such as a woman’s cycle, structure and function of the male sexual organs and the effects of different contraceptives in terms understandable to pupils. The film is suitable for an entire series of lessons, with the teachers deciding themselves on the basis of the menu struc- ture what content is appropriate for a class.

Microcosm

We perceive the world we live in with our sense organs. However, perception with our senses represents only a limited part of the cosmos we live in. There is a world eluding the perception of our eyes. It exists hidden away for its cosmos is extremely small. The world of microcosm. This world is full of fascination and surprises. Up to the 1930s a deeper penetration into the microcosm was impossible. Only the invention of a new technology enabled us to render still smaller details of the microcosm visible to the human eye. A magnification of up to a thousandth millimetre has become possible. This film provides a profound insight into the microcosm. Rare pictures of mites, water bears and other creatures, made visible by means of various microscopes make the film an extraordinary experience. In addition, the DVD includes bonus material explaining the functions of the different microscopes with the help of diagrams. Due to the combination of the subjects of microcosm and microscopes, this DVD is perfectly suited for biology classes as well as physics lessons.

Penguins

Most people know penguins only from the zoological garden. There they arouse many visitors’ interest. This is, on the one hand, because of their peculiar black-and-white colouring, which reminds you of a tail coat, on the other hand, because of their upright walk. We find penguins amusing or funny; but if we knew more about their extraordinary skills, we would not laugh about them but gaze at them in wonder and reverence.
