Today Mika and I wanted to play outside , but then we saw that the sky was completely dark, even though it was still the middle of the day. There were really dark grey and even black clouds in the sky.

I'm so excited that it's finally winter and it will soon be snowing. Earlier, I was thinking about the snowman that Mika and I built last year.

Mika and I are currently visiting (AC)³ researcher Sofie Tiedeck at the Alfred Wegener Institute in Potsdam.

Today I went to the playground with Mika. It was great fun. First we went on the swings, then we had a few goes on the roundabout.

Today, Dad drove me and Mika to the park near our house. On the way there, we saw our friend Fathima riding her bicycle to the park.

Today was a beautiful sunny fall day. Mika and I went to the park and had ice cream. There was a little snowflake on the ice cream cup, which got me thinking. I have noticed that drawings of snowflakes often have six corners. But is this also the case in nature?
