在四季中漫步
Do you know that our planet is tilted? This means that sometimes we are closer to the Sun. Sometimes we are further away. And sometimes we are somewhere in between. This is why we have spring, summer, autumn and winter.

When the Sun shines in spring, plants begin to grow. Can you see the new shoots and leaves everywhere?

In the middle of summer, the day is very, very long. There is daylight when you wake up. It might still be light when you go to bed.

In autumn, we move away from the Sun. This means that the day grows shorter and that the weather grows cooler.

In winter, the Sun rises late and sets early. Winter days are the shortest and coldest of all. This is because we are furthest from the Sun.
