I. DIALOGUE
B: Joe asked me something about science just now. But I didn’t know the answer.
G: I’m good at science. Ask me.
G: I’ll explain it in a simple way. Light comes through the air from the sun in waves.
B: The light is in many colors, right?
G: Right. Blue light waves are smaller than air molecules. They sometimes get absorbed by these molecules.
G: Then the blue light waves scatter in many directions. Your eyes see this blue light from above you, after it leaves the air molecules.
B: So that is what makes the sky blue! What happens to the other colors?
G: They reflect off the things that they hit. Your shirt is red because our eyes see the red light reflected from it.
B: Now I understand why the sky is blue!
