Hi there! Have you ever looked up and wondered why the sky is blue? Let me tell you a simple story.
The sun shines white light, and when this light comes to Earth, it meets the air. The air is like a big blanket of tiny invisible pieces called 'particles'. When sunlight hits these tiny pieces, it spreads out in many colors, but the blue color spreads out the most and lights up the whole sky.
So, the sky looks blue because the blue color from the sun spreads everywhere when the sunlight meets the air. That’s why when you look up, you see a big blue sky!
Isn't that fun to know?
