Earth in Space

Earth takes a whole year to orbit the Sun, and its tilted axis is what gives us summer and winter — while moons and satellites circle around too.

I can explain how Earth's orbit and axial tilt cause the seasons, and describe moons and satellites.

Kavi Tilts and Travels

Kavi leans a little to one side and starts walking in a big circle 🔄. "Watch me — I'm Earth! I travel all the way around the Sun once a year, and I stay a bit tilted the whole time. When my tilted top leans toward the Sun ☀️ it is summer; when it leans away it is winter. And up above floats my friend the Moon 🌙. Come find out how the tilt makes the seasons — and meet the satellites that circle the Earth!"

What your child will learn

1One orbit, one year — and four seasonsEarth travels all the way around the Sun once a year. Its axis stays tilted the same way the whole trip, so each half leans toward or away from the Sun as the year goes on. Tap each step and watch it go round.

2Why summer and winter are differentSame planet, same Sun — but one half is tilted a different way. Tap each card.

3Earth in space: orbit, tilt, moons and satellitesA satellite is anything that orbits a bigger object. Some are natural (moons); some are built by people. Tap each part to learn what it does.

4Your turn: explain orbit, tilt and satellitesThink like a scientist — guess first, then tap to check! Tap Next test for more.

A peek inside

It is July, and it is hot summer where Kavi lives in the northern half of Earth 🌍. What makes it summer there and not winter?

Earth's axis stays tilted the same way all year. In July the northern half leans toward the Sun, so sunlight hits it straight and direct — long, warm days. It is the tilt, not the distance to the Sun.
