Koko learns the moon stays round but looks different as we see various lit-up parts.
The moon doesn't change shape We see different parts lit by the sun Observing the night sky
📖 Story Script
                    Koko:
                    Owlo, last night I looked out my window and saw the moon. It was round and bright like a big cookie.
                
                    Owlo:
                    That sounds beautiful, Koko. The full moon is wonderful to see.
                
                    Koko:
                    But the night before, it looked different. It was skinny like a banana. Does the moon change shape?
                
                    Owlo:
                    What a smart question, Koko. Many children wonder about that. The moon does not really change shape at all.
                
                    Koko:
                    It does not? But I saw it change with my own eyes.
                
                    Owlo:
                    I know it looks that way. Come with me to the science lab. I want to show you something special.
                
                    Owlo:
                    Look at this orange ball. This will be our pretend moon. Can you hold it for me?
                
                    Koko:
                    Okay! It is nice and round, just like the real moon.
                
                    Owlo:
                    Perfect. Now I will turn off the lights. Do not worry, I have a flashlight here.
                
                    Koko:
                    Ooh, it is dark in here now.
                
                    Owlo:
                    Good. Now I will shine the flashlight on one side of your orange ball. What do you see?
                
                    Koko:
                    I can see the bright side where the light hits. But the other side is dark and hard to see.
                
                    Owlo:
                    Exactly right. Now walk slowly around me in a circle. Keep holding the ball.
                
                    Koko:
                    Okay, I am walking around you now.
                
                    Owlo:
                    Do you see how different parts of the ball look bright as you move?
                
                    Koko:
                    Yes! Sometimes I see the whole bright side. Sometimes I only see a little bright part on the edge.
                
                    Owlo:
                    That is exactly what happens with the real moon. The sun shines on it like my flashlight.
                
                    Owlo:
                    As the moon moves around Earth, we see different parts that are lit up by the sun.
                
                    Koko:
                    So the moon is always round like my ball?
                
                    Owlo:
                    Yes, always. We just see different bright parts at different times. That makes it look like different shapes.
                
                    Koko:
                    Oh! So when I saw the banana moon, I was only seeing a little bit of the bright part?
                
                    Owlo:
                    Exactly right, Koko. You are thinking like a real scientist now.
                
                    Koko:
                    This is so cool. Can we turn the lights back on now?
                
                    Owlo:
                    Of course. Now, can you tell me what you learned today about the moon?
                
                    Koko:
                    The moon does not really change shape. It is always round like this orange ball.
                
                    Koko:
                    But the sun shines on it, and we see different bright parts as it moves. That makes it look like different shapes.
                
                    Koko:
                    Tonight I will look out my window again. I want to see what shape the bright part is.
                
                    Owlo:
                    That is wonderful, Koko. You can look at the moon every night and watch it change. Maybe you can draw pictures of what you see.
                
                    Koko:
                    I will do that. And I will show my drawings to you next time. Thank you for teaching me about the moon, Owlo.
                
                    Owlo:
                    You are very welcome, Koko. I love your curious questions. Keep looking up at the sky.
