Blogging

The weblog or blog, for short, as a medium is not much older than this century. Blogs came into being in the World Wide Web as ’messages from below’, as web pages from web creators who wanted to share their view of the world with the world. They are short notes, long texts, pictures, videos, which are posted loosely and at random intervals to the world for an undefined public.

Blood

One moment of distraction and the damage is done: Tim has slipped and has scraped his knee. The wound begins to bleed. Back home, Tim is comforted by his mother and a plaster is put on the knee. Actually, this is not necessary any more because Tim’s body has already started to help itself by forming a scab on the wound. A skin injury makes it possible for germs and dirt to enter the body. To prevent this from happening our organism repels all foreign substances, beginning at the same time to close the wound. This is done with the help of blood clotting, which starts directly when blood gets into contact with the outside world for example.

Blossoms

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.

Breakfast

Breakfasting – this morning ritual exists in almost every country, every culture and every century. However, food, time, process and duration vary from country to country, family to family, person to person. The first meal of the day is of particular importance. It allows us to fully wake up. Around the table, the day's schedule is planned. Here is where the family meet. Above all, breakfasting is important for children. When they get up, the energy storage from the previous day is empty because the body consumes energy also during rest and sleep. A healthy, substantial breakfast helps us to gather new strength.
