Explain why the sky is blue
The sky looks blue because of something called scattering. When sunlight hits the air, it scatters in all directions. Blue light scatters more than other colors because it travels in shorter, smaller waves.
Real-life example
Think of a glass of water with blue dye. When you stir it, the blue spreads everywhere, just like light spreads in the sky.
Step-by-step
1. Sunlight travels through space. 2. It hits the Earth's atmosphere. 3. Blue light scatters more than other colors. 4. We see the blue light all around us in the sky.
