This is what I wrote before I researched how day and night happens:
Then I made a clip with my partner showing what I know now:
Something I didn’t know is the the earth has an axis. It is an imaginary line going through the middle of the earth. I thought that the world is straight. That is not true!! The world is actually on a 23.5° angle.
Over the time of making the clip, I learnt not just how day and night happens but how the seasons change to. We get seasons because the earth does not just spin around but it goes in a circle around the sun.
