Alkali Metals
Properties, Examples, Relationship
What do lithium batteries, table salt and firework rockets have in common? All of them contain compounds of alkali metals. Alkali metals are members of the first group of the periodic table of the elements. The metals in this group are lithium, sodium, potassium, rubidium, caesium and francium. The word “alkali“ is derived from the Arab “al-qalya“ for potash, the colloquial term for potassium carbonate. In this film we want to take a closer look at the representatives of this family of elements, compare their properties, investigate the chemical behaviour and see where we encounter their chemical compounds in everyday life. Alkali metals and alkaline solutions – also called basic solutions – are noxious for the skin. Therefore, additional protective gloves should be worn – apart from the obligatory protective goggles required in laboratory work.

Inclusion
Madita is eleven and blind. She does not want to go to a special school but to a regular grammar school. She says she feels "normal" there. Jonathan is eight and has a walking disability. He likes going to the school where he lives. Here, his best friend sits next to him. Max Dimpflmeier, a teacher who is severely deaf, explains that school life is not easy. Quote Max Dimpflmeier: "You don't want to attract attention, you want to avoid saying that it is necessary for you that 70 people adjust to your situation." People on their way to inclusion.
