When Christopher Columbus set
sail on his journey in 1492, he
encountered stiff opposition – it
is thought many people feared
he would fall off the edge of the
Earth (which many people
thought to be flat).

The Bible
Many early Christians believed the Earth was flat
because of references found in the Bible. For
example:
“I looked, and there before me stood a tree in the
middle of the land. Its height was enormous. The
tree grew large and strong and its top touched the
sky; it was visible to the ends of the Earth.” Daniel
4:10f
However the Bible does not state that the Earth is
flat.

The Sun is the largest object in the solar
system.
It is our closest star and is believed to be
over 4 billion years old.
There are storms on the surface of the Sun.
These storms are known as ‘sunspots’,
because they look like spots on the sun.

The centre (or core) of the Sun is very hot.
A process called ‘nuclear fusion’ takes
place there. Nuclear fusion produces lots
of energy. Some of this energy travels out
into space as heat and light. Some of it
arrives at Earth.
It is very dangerous to look directly at the
Sun.

ShadowsShadows
Shadows are formed when light from a source
is blocked. When the Sun shines on an object
it forms a shadow on the ground.
NextIndex
Shadows change during the day.
NextIndex
From the position of the shadow you can see
the Sun rises in the East and sets in the West.
NextIndex
The Sun appears to move through the day but,
in fact, the Sun does not move. It is the Earth
rotating on its axis, which makes it seem that
the Sun is moving.
As the Sun appears to move and gets higher in
the sky, the shadows get shorter. In the
morning and evening the Sun is lower in the
sky so the shadows are longer.
NextIndex
Night and DayNight and Day
As the Earth spins on its axis the part that is
facing the Sun will be in the light (day).
The part of the Earth not facing the Sun will
be in darkness (night).

The Earth – Facts
The Earth is one of nine planets in the
Solar System.
It is over 149 million miles away from the
Sun.
The Earth spins around a line which goes
through it from the North Pole to the South
Pole. This is known as the Earth’s axis.
NextIndex
The axis does not
point straight
upwards. It is tilted
slightly.

The Moon orbits the Earth
It takes 28.3 days for one complete orbit
(lunar month)
The Moon does not make its own light.
You only see the Moon because it reflects
light from the Sun.
NextIndex
The amount of the Moon seen changes from
day. These changing views are called the
phases of the Moon.
