States of Aggregation
Solid, Liquid, Gaseous
It is winter. Snow and ice transform the landscape into a fairy tale scenery. At sub-zero temperatures, ice crystals form on branches and other objects. The snow cover is not always uniform but sometimes shows varied structures of snow and ice crystals as well. Snow is frozen rain, that is, precipitation falling from the clouds. Clouds, in turn, consist of gaseous water vapour which transforms into precipitation in certain conditions. Where the sun shines and temperatures rise again, snow and ice begin to melt. Thaw sets in, and snow and ice change into water again. But snow and ice can also exist simultaneously. Even at high minus temperatures, streams and rivers still carry water. On their banks, exciting ice formations can develop as a result. Stagnant waters, such as lakes and ponds, however, tend to freeze because the water in them hardly moves. The solid, liquid and gaseous states are the three classic aggregate states. We encounter the interplay between water vapour, liquid water and ice in many situations. Complex physical processes lie behind it. Let us take a closer look at them now.

Pupils Practise Inclusion
When people come together, no matter under what concomitant circumstances – ultimately, it is about how these people meet and how openly they interact with one another.
Mobile Learning II
Oh, what’s that? Original soundtrack Thissen: “As our children grow up in a media world and naturally handle the media, they should also be a topic in school.“ An older child says the point is that they don’t just load down apps but create things themselves that haven’t existed so far. Hi, I’m Jana. A propeller hat. I’ll put it on. Now I’m no longer a simple rhino, but a flying rhino. Original soundtrack Thissen: “It’s exactly the great flexibility of tablets that promotes very personalised and adapted learning.” Original soundtrack Welzel: “It’s fascinating to see how the children grow with their products and how they always want to improve them.” The Westminster Abbey is a church in London for the royal family. Original soundtrack Welzel: “And?“ They think it is ok.
