Blossoms
Structure and Pollination
In impressive pictures several interesting biological topics are conveyed by this film: knowledge of the structure of blossoms, their variety of forms as well as significance and purpose of their colours and scents. Thus it becomes comprehensible why blossoms are so differently structured, how self pollination is avoided and which evolutionary achievement is behind the symbiotic interaction between blossoms and pollinators. Pollination is a “deal“: the plant offers the insects nectar in exchange for the transport of the pollen. Prerequisite for this is the mutual adaptation process of the blossom to the mouthparts of the insect and vice versa. That cheating goes on during this “business relationship” between plant and animal is illustrated with the example of flower mimesis. The perfect way in which blossoms succeed in attracting insects without offering them nectar in return is another highlight of this film. Together with the extensive accompanying material the DVD is perfectly suited for use in the classroom.

Air Traffic
Being able to fly has been a dream of humanity from time immemorial. But it does not even date back a century that people actually started being able to travel through the air. Since the 1960s, the number of flight passengers has been constantly increasing. Thus, the airspace is no longer dominated by birds but by man-made flying objects.
