A hands-on lab for explorers, age 6–9
Someone far away is eating breakfast while you eat dinner. Penguins in Australia are sliding into winter. Grab the planet, turn it, find out why.
Any order. Collect ✦ for every discovery.
👆 Drag the Earth — turn it any way you like
So… what is really making day and night?
The single most important idea: the Sun stays put and the Earth turns. The Earth completes one full spin in about 24 hours, which is why we have a day. Ask your child, out loud, "If Pip keeps turning, when will he see the Sun again?" Let them predict before dragging. Night is not "no Sun" — it is "the Sun is on the other side of the Earth, where you cannot see it."
👆 Drag the world to spin it
Loading mission…
Time zones are the day/night idea turned into a clock: noon is wherever you happen to face the Sun. The final mission is a trick — it is impossible to have all five cities in daylight at once (they span 15 hours apart). That is the wonder: on this planet, it is always morning somewhere. Note: these are standard-time offsets; daylight-saving time can shift a city by one hour.
👆 Drag the Earth around its year
Drag the Earth and watch the two poles fight.
Mission 1 — Slide the Earth so the NORTH has summer. (Watch the red pole!)
Same sunlight, two different landings. Drag the Sun along the sky from low to high, or tap the buttons.
Two ideas do all the work: (1) the axis keeps a fixed direction in space (pointing near Polaris), so half the year the north leans sunward; (2) a leaning surface gets the Sun lower in its sky, and low light spreads over more ground — the torch-on-paper trick. The real cause is the angle of sunlight, not distance. Have your child answer "who has winter when we do?" — the other hemisphere, always.
You can explain day and night, you can read the world like a clock, and you know what the tilt really does. That is astronomy most grown-ups never got to play with.
1. The Sun holds still. The Earth spins, so each place gets its turn in the light — that's day and night.
2. Because of that spin, noon is different everywhere. The world is one big clock face.
3. Seasons come from the lean, not the distance. The north leans toward the Sun while the south leans away — so we get summer and winter at the same moment, on opposite halves of the Earth.
