The Sun stays still. Our Earth spins all the way round once every 24 hours — that's one whole day. The side facing the Sun has day; the side turned away has night. Spin the Earth and watch the little house move from day into night!
The Earth is tilted as it travels round the Sun all year. When your part of Earth tilts towards the Sun you get summer — longer, warmer days. Tilted away, it's winter — short, cold days. Step through the seasons!
1. Is it the Sun moving or the Earth spinning that makes day and night? The Earth spinning! The Sun stays still.
2. When it's daytime here, what is it on the other side of Earth? Night-time — that side is turned away from the Sun.
3. Why is summer warmer than winter? Our part of Earth tilts towards the Sun, so days are longer and the sunlight is more direct.
4. How many seasons are there, and what's the order from spring? Four: spring, summer, autumn, winter.
The Earth spins once every 24 hours to make day and night. And because the Earth is tilted as it circles the Sun each year, we get the four seasons. It was never the Sun moving — it was us all along!
