Kavi's Backyard Planets
Kavi tips out a bag of balls — a huge one and eight little ones ☀️🪐. "I'm making a Solar System model! The big ball is the Sun, and it goes right in the middle. Then the planets circle around it in order: tiny Mercury closest, then on and on to far-away Neptune. Come on — let's build it, sized and spaced just right!"

What your child will learn
1What's in a Solar System modelA good model shows the Sun and all 8 planets. Tap each part to see its job in the model.
2Small rocky planet or big gas giant?The 4 planets closest to the Sun are small and rocky. The 4 farther out are huge balls of gas. Tap the right box!
3Build it the right wayUse what you know to predict, then tap to check! Tap Next test for more.
4A good model, or a muddled one?Two children build a Solar System model. Tap each card — which one is built sensibly?

A peek inside
Kavi starts the model with one big ball. Where should the Sun go?
The Sun sits in the centre, and all the planets circle around it.
