The Sun is a star and is at the centre of our solar system.

Our Moon is an object that travels around planet Earth.

We can compare the relative size of objects to help us understand how big they are.

We can use scale to help us understand the size of very big or very small things.

The relative sizes of the Earth, Sun and Moon (non-statutory)

Science

In the Earth, Sun and Moon unit, pupils learnt about the cause of day and night. In the Solar system and beyond unit they will build on this knowledge to learn about the motions that cause days and seasons on the Earth.

In the Seasonal changes units, pupils learn that day length varies throughout the year. In this Earth, Sun and Moon unit, pupils will build on this knowledge to use the idea of the Earth's rotation to explain day and night and the apparent movement of the sun across the sky

Physical activity and equipment requiring safe use

Use of equipment that may require supervision for safety, e.g. scissors in KS1, needles, paint, knives, cooking.

Starting with the largest, put these objects in order of size.

Match the object in space with its approximate diameter.

What do we mean when we talk about the relative size of objects in space?

It is helpful to know how much each object weighs

They are too big to draw or model in their actual size.

It makes it easier to understand smaller numbers.

Why is it useful to use a scale when drawing or modelling the sizes of objects in space?

We use secondary sources of information when we do {{}} to find out more about something.

How many times could Earth fit into the Sun?

If something has been divided into four equal parts, how much is each part?

What is the name of this object in space?

If we wanted to find out facts about something, which of these would **not** be a good place to look for information?
