Why is it dark at night? And why are there seasons?

The Sun doesn't move as much as we think: it's the Earth that turns!

🌗 Day and night

The Earth turns on its axis in 24 hours. When your side faces the Sun, it's daytime. When it's on the other side, it's night.

🍂 The seasons

The Earth also turns around the Sun in 1 year. It is slightly tilted: sometimes your country receives more light (summer), sometimes less (winter).

🤯 Did you know?

When it's summer here, it's winter in Australia! And near the North Pole, the Sun stays visible all night in summer: it's called the midnight sun.

The scientist's words

The Earth turns on its axis (rotation) in 24 h and around the Sun (revolution) in 365 days.

🔦 Experiment: in a dark room, a lamp = the Sun, a ball with a small sticker = your house. Spin the ball slowly!
