Our Solar System
Know that there are other planets besides Earth and that our group of planets orbiting the Sun is called the solar system, and that space is the vast area beyond Earth's sky
What a learner can do afterwards
- State that Earth is a planet and there are other planets too
- Use the term 'solar system' to describe the Sun and the planets that orbit it
- Explain that space is the area beyond the Earth's sky, where the planets and stars are

Earth is a planet. It is not the only one. Many other planets exist too. All of them circle around the Sun.
Leo asks his dad a question. 'What do we call the Sun and its planets?' Dad says, 'That group is called the solar system.'
Space is very big. It is beyond Earth's sky. That is where planets and stars are.
Earth and other planets circle the Sun in our solar system.

The Search for Life
Earth is one of eight planets that travel around the Sun. Together with the Sun, they make up our solar system. Space is the huge, dark area beyond Earth's sky where the planets and stars live. Scientists look at other planets to see if anything alive might be there. So far, Earth is the only planet we know with life. But we keep looking because the building blocks for life exist in clouds between the stars.
1.6 A Tour of the Universe
Imagine a spaceship leaving Earth. First you pass the Moon, then the other planets: Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune. Beyond them are icy dwarf planets and comets. The Sun is a star, and there are billions of other stars in our galaxy. Galaxies are huge groups of stars. The universe is everything there is: all the galaxies, all the space between them, and all the stuff inside them.
How to Make a Solar System Model
You can build a model of the solar system to see how the planets line up. Use a big ball for the Sun and smaller balls for the eight planets. Mercury, Venus, Earth, and Mars are rocky and small. Jupiter, Saturn, Uranus, and Neptune are gas giants and much bigger. Hang them in order from the Sun.
