It is bedtime. Ama is in her moon pyjamas. Turtle is ready for bed too. Outside her round window, the sky is dark and full of stars.
Good night, Ama. Good morning, Kwame!
At bedtime, Ama says good night to her cousin Kwame, who is just eating his breakfast far away. With a torch and an orange, Papa shows her why.
Papa holds up the tablet. There is Kwame, her cousin, far away! “Good night, Kwame!” says Ama. Kwame laughs. “Good morning, Ama! I’m eating my breakfast.” Sunshine fills his kitchen.
Ama blinks. “Good morning? But it’s night!” She looks at her dark window. Then she looks at Kwame’s sunny window. “How can it be night here and morning there?”
Papa smiles. “Let’s find out.” He switches off the big light. He brings a little torch and an orange. “The torch is the Sun,” says Papa. “The orange is our Earth.” Ama sticks on a star for her home. Papa sticks a star on the other side for Kwame’s home.
Click! Papa shines the torch at the orange. Ama’s star faces the light. “That’s daytime at our house,” says Papa. Kwame’s star is on the dark side. “And night at Kwame’s house!” says Ama.
“The Earth keeps turning, like a spinning top,” says Papa. Ama turns the orange slowly, slowly. Her star slides into the dark. Kwame’s star slides into the light. “Now it’s night for me and morning for Kwame!” Ama whispers.
“Does the Sun go to sleep at night?” asks Ama. “No,” says Papa gently. “The Sun keeps shining. Our Earth turns us away from it. It takes about one day to turn all the way round.” Ama smiles. “So the Sun is shining on Kwame now,” she says.
Ama snuggles under her blue blanket with Turtle. She waves. “Good night, Kwame! Enjoy your breakfast.” Papa puts the tablet away. Ama whispers, “Good morning, Sun. Shine bright for Kwame.” The Earth keeps turning. Soon it will be Ama’s turn for morning.
the end
let’s play: day and night with an orange
- In a dim room, shine a torch at an orange or a ball. Point it at the orange, never at anyone’s eyes.
- Put a sticker on the orange for your home.
- Hold the orange top and bottom, and turn it slowly.
- Say “day” when the sticker is in the light and “night” when it is in the dark.
- Put a second sticker on the other side. When one sticker has night, what does the other one have?
talk about it
- Why was Kwame eating breakfast when Ama was going to bed?
- What did Papa use for the Sun, and what did he use for the Earth?
- Does the Sun go to sleep at night?
- What would you say to someone far away who is just waking up?
for grown-ups
What this story helps with: The Earth keeps turning. The side facing the Sun has day and the side turned away has night, so when it is night where we live, it is daytime far away on the other side of the world.
This story shows that day and night happen because the Earth keeps turning: the side facing the Sun has day, and the side turned away has night. So while we sleep, it is daytime for people on the other side of the world. The Sun doesn’t go to sleep; it only looks that way because we turn away from it. At bedtime, you could wonder together what someone far away might be doing right now. Then try the torch-and-orange game in a dim room, keeping the torch pointed at the orange and not at anyone’s eyes.
