The sun, the moon and the sky for the youngest scientists: study cards a grown-up can read aloud, the tricky ones, a practice quiz at three levels — Foundation, On-Level, and Challenge — and a lab where you order a day from sunrise to sunrise, sort day sky from night sky, label a sunset, and graph the daylight in each season. Work here, or print it and use a crayon — both count.
Morning. The sun is low in the east, so the shadow stretches out long.
Short shadow means the sun is high, so it is near noon. Long shadow means morning or evening. The sky does the same thing every day, so you can read it.
Two things people get wrong
⚠️People often think…
The stars go away during the day.
They are right where they always were. The sun’s light is so bright it washes them out, the way a flashlight beam hides a candle. Nothing moved.
The sun hides them. It does not send them away.
⚠️People often think…
The moon changes shape — sometimes it is a sliver and sometimes it is round.
The moon is a round ball the whole time. Half of it is always lit. What changes is how much of the lit half we can see from here.
Always round. We just see less of the lit side.
Read the sky
1Watch one
A kid’s shadow is very short. What time is it?
Look at the shadow: short or long?
Short. A short shadow means the sun is high up.
The sun is highest in the middle of the day.
So it is about noon. ✓
2Do one with me
Fill in what the sky does.
A short shadow means it is about
In the day the stars are still
The shape of the moon is always
💬One sentence, then you move on
Why can you not see stars in the daytime?
3Try one
Which season has the longest days?
I want a hint first
It is the hot one, when school is out and it stays light late.
Where this goes
Where this lives
Knowing when it gets dark, when to bring a coat, when the days start getting longer again. The sky keeps the same schedule every year.
What this feeds
Next unit is what living things need to stay alive.
Name one thing in the sky you have watched change.
One card at a time — tap “Show me” to check yourself, then Next. Start at Foundation; when those feel easy, climb.
Helpful Hints
🪜 Day, month, year — the ladder
The sun comes up in the east and goes down in the west, every day → the moon changes shape, sliver to full to sliver, every month → the stars come out when it’s dark and each season has its own → summer days are long, winter days are short, every year.
Sun for the day, moon for the month, seasons for the year.
🤝 The whole idea
The sky does the same things over and over. If you watch and count, you can tell what it will do next.
Watch, count, predict.
⚠️ Tricky ones
The sun does NOT move — Earth spins. It only looks like the sun moves.
The moon is always round. We just see different amounts of its lit side.
The stars are up in the day too. The sun’s light hides them.
The moon can be out in the day. The sun is never out at night.
Short shadow = noon. Long shadow = morning or evening.

🎯 How the test will ask
Pictures of the moon — “put them in order” (sliver, half, full).
A picture of a kid and a shadow — “what time is it?” (short = noon).
“Which season has the most daylight?” (summer).
“Where do the stars go in the day?” (nowhere — the sun hides them).
✅ Can you…
Say where the sun comes up and goes down?
Draw the moon three ways?
Tell noon from morning by a shadow?
Name the season with the longest days?
Explain why we don’t see stars in the day?

Lab
Work like a scientist: label the diagrams, turn the table into a graph, then write a claim with evidence and reasoning. Every lab checks itself on the spot, and hints are free.

This is your record of the module on screen — it stays here and goes nowhere. Independent means you got it right on the first tap; supported means you got it after the explain-and-retry, or marked ‘I had it’ on a revealed answer. Both count, and neither is a grade. If your teacher asks, copy the row or show them this screen.
