Space
The Earth, Sun and Moon
What do we know?
• Draw a picture of the
Earth, Sun and Moon
as seen by a traveller
in space.
• Think about size,
shape, colour,
position.
What do we know about Earth?
• Is the Earth flat?
For centuries, people assumed the
Earth was flat……it looks flat………
It was the Ancient Greeks who first
started asking questions. They noticed
that ships crossing the horizon at sea
appeared to dip out of sight. Could the
Earth be round?
It is only in the last 40 years that we
have had photographic evidence from
Space to prove that the Earth is
spherical.
What do we know about the Sun?
• Is the Sun a planet? What is it?
• Does the Sun move?
• Is the Sun bigger than the Earth and
Moon?
The Sun is a star.
The Sun does not move around the planets. The Sun stays in one place.
The planets move around the Sun.
The Sun is over 1,000,000 times larger than the Earth

The Sun
The Sun is the most prominent feature
in our solar system. It is the largest
object and contains approximately
98% of the total solar system mass.
One hundred and nine Earths would
be required to fit across the Sun's disk,
and its interior could hold over 1.3
million Earths. The Sun's outer visible
layer is called the photosphere and
has a temperature of 6,000°C. This
layer has a mottled appearance due to
the turbulent eruptions of energy at the
surface. Solar energy is created deep
within the core of the Sun. It is here
that the temperature (15,000,000° C)
and pressure (340 billion times Earth's
air pressure at sea level) is so intense
that nuclear reactions take place.
What do we know about the Moon?
• Is the Moon a planet?
• How does the Moon move?
•
•
The Moon is simply a moon!
Moons move around planets.
The Solar System
• What other planets are in our Solar System
other than Earth?
• Write a mnemonic to help you remember the
order.

My Very Easy Method, Just Set Up Nine Planets!
Size and Distance in Space
• In groups create a ‘to scale’ model of the
distances between Sun and planets on the
field.
• Use the measurements provided to draw
the objects to scale and measure the
distances to scale.
The planets of our Solar System.
• Next week we are going on a journey into
space to visit each of the nine planets and
discover more about our Solar System.
• Do you know any fascinating facts? Bring
them to share with us next week.
