Earth and Space for Kids: Solar System, Moon & More

Tap your way round labelled science diagrams: the planets going round the Sun, the layers of the Earth, the water cycle, the atmosphere, the Moon's phases, the seasons and a volcano. Every planet has its own fact sheet. After exploring, answer 8 questions and put things in order. Useful for the Earth and space topic in primary science (Year 5 in England).

How to play

  1. Choose a topic: the solar system, Earth's layers, the water cycle, the atmosphere, the Moon's phases, the seasons, a volcano, a mix, or Put it in order.
  2. Explore the labelled diagram first: tap any part to learn about it. The solar system's planets turn and go round the Sun (pause them to look closely), and each one has a fact sheet.
  3. Then answer 8 questions by tapping the part that is named or described. Most topics end with a Put it in order puzzle: tap the planets from the Sun outwards, the Moon's phases from the new moon, and so on.

What kids learn

The Sun and the eight planets in order, with each one's size, distance, day, year, moons and temperature; the four layers of the Earth; the water cycle; the five layers of the atmosphere; the eight phases of the Moon; why we have seasons and day and night; and the parts of a volcano.

Tips for parents and teachers

Questions from grown-ups

What age is this for?

About 6 to 12. It matches what primary EVS and science books teach about space, the Earth, water and volcanoes.

Are the diagrams to scale?

No. Everything is drawn so it's easy to see and tap; the real Sun would be far bigger and the planets much farther apart. The fact sheets give the real numbers.

Why are the Moon phases and seasons 'for the northern half'?

The Moon looks lit on opposite sides, and the seasons are opposite, in the two halves of the world. The diagrams show the northern half, and the questions say so.

Why is Pluto missing?

Since 2006 scientists call Pluto a dwarf planet, so the solar system has eight planets.

Can it be played without sound?

Yes: every question is written above the diagram.

Does it work for a whole class?

Yes: put it on the projector, show the labelled diagram, then let children call out or come up and tap.

Is it free? Does my child need an account?

Yes, it's free, with no sign-up, login, or download, and it never asks for personal details. It runs in the browser on phones, tablets, and computers.
