📖 Story Script
                    Koko:
                    Owlo, look at the clouds! They are so fluffy and white today.
                
                    Owlo:
                    Yes, Koko, they look like cotton candy floating above us.
                
                    Koko:
                    The sky behind them is so pretty and blue. Why is the sky blue, Owlo?
                
                    Owlo:
                    What a wonderful question, Koko! Let me show you something special.
                
                    Owlo:
                    Come with me to the art room. I have colorful prisms there.
                
                    Koko:
                    Wow, this room has so many colors everywhere!
                
                    Owlo:
                    This clear triangle is called a prism. Watch what happens when sunlight shines through it.
                
                    Koko:
                    Oh my goodness! I see a rainbow on the wall!
                
                    Owlo:
                    Yes! Sunlight looks white, but it is actually made of many colors mixed together.
                
                    Koko:
                    Like red, orange, yellow, green, blue, and purple?
                
                    Owlo:
                    Exactly right, Koko! Those are all the colors hiding in sunlight.
                
                    Koko:
                    But why does the sky show only blue? Where do the other colors go?
                
                    Owlo:
                    Great thinking! The air above us is full of tiny, tiny bits we cannot see.
                
                    Owlo:
                    These tiny bits are called air molecules. They are super small.
                
                    Koko:
                    Smaller than a grain of sand?
                
                    Owlo:
                    Much, much smaller than that! You need a special microscope to see them.
                
                    Koko:
                    Wow, that is really tiny!
                
                    Owlo:
                    When sunlight travels through the sky, it bumps into these tiny air molecules.
                
                    Owlo:
                    The blue light bounces and scatters all around the sky.
                
                    Koko:
                    Like when I throw a ball and it bounces everywhere?
                
                    Owlo:
                    Yes, just like that! Blue light bounces the most because it is special.
                
                    Koko:
                    What about red and yellow? Do they bounce too?
                
                    Owlo:
                    Red and yellow travel straight through without bouncing as much.
                
                    Owlo:
                    That is why we see blue all around us in the sky.
                
                    Koko:
                    So the sky is blue because blue light likes to bounce everywhere!
                
                    Owlo:
                    Perfect, Koko! You understand it wonderfully.
                
                    Koko:
                    What happens when the sun goes down? The sky turns orange and pink.
                
                    Owlo:
                    Excellent observation! We can explore that mystery another day.
                
                    Owlo:
                    Now, can you tell me what you learned about the sky today?
                
                    Koko:
                    Sure! Sunlight has many colors mixed together, like a secret rainbow.
                
                    Koko:
                    When sunlight goes through the sky, it bumps into tiny air bits.
                
                    Koko:
                    Blue light bounces all around the sky, so we see blue everywhere.
                
                    Koko:
                    Next time, I want to learn why sunsets are orange!
                
                    Owlo:
                    That sounds like a perfect plan, Koko. You are becoming quite the scientist.
                
                    Koko:
                    Thanks, Owlo! Learning with you is so much fun.
