Bees, Bumblebees and Wasps

Our smallest domestic animals, the honey bees, belong to the insect order of hymenoptera just like bumblebees, wasps and ants. Many of these insects live in huge colonies with division of labour and a caste system. However, there also are less conspicuous small hymenoptera like, for instance, the mason- bee, which on its own builds complex nests for its offspring and supplies it with food. We haven’t even noticed that it has followed us into our human settlements and we don’t consider that we are taking away the habitats from these small interesting insects. This film pays attention to all these important plant pollinators, allows insights into the work of bees and wasps and shows how we can observe and protect them.

We learn that there are various hormones, where these are produced and how they work. We get acquainted with people whose lives have been influenced by a hormone deficiency or a hormone excess.

Kräuter und Gewürze

Das Wort Kräuter kommt von Kraut. Als Kraut bezeichnet man meist die oberirdischen Teile einer Pflanze, aber was ist mit den Wurzeln? Das Wort wiederum steckt in Gewürz. Blattgewürze werden nur als Gewürz bezeichnet, wenn sie getrocknet sind. Im frischen Zustand zählen sie zu den Kräutern. Fest steht, eine klare Abgrenzung gibt es nicht. Viel wichtiger ist es, ein paar Kräuter und Gewürze zu kennen, um sie im Alltag richtig einzusetzen.
