Structure of the Forest

Forests are more than an accumulation of trees. The individual tree is more than a valuable source of wood. From its roots to its crown, it offers habitats to a variety of the most different creatures. The older a tree, the more valuable it becomes to many forest inhabitants. And even in death it is still full of life. If you take a closer look at a forest, you notice that the plants grow to different heights. They form storeys like those of a house. At the top level there are only the big trees. From a bird’s perspective we see that the highest specimens in the forest form a closed canopy. In summer, the treetops resemble big parasols shading the forest floor. Depending upon how much sunlight filters into the depths, this has consequences for the forest vegetation.

The “Sugar” DVD covers the sugar beet and sugar produc- tion in detail. Simple and clear pieces of information allow the children to easily understand the individual stages from sowing the seeds to processing the beets in the sugar factory.
