In History
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 410f However the Bible
does not state that the Earth is flat.

The Sun Facts

• 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 Sun Facts

• 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.

Shadows
Shadows are formed when light from a source is
blocked. When the Sun shines on an object it
forms a shadow on the ground.

From the position of the shadow you can see the
Sun rises in the East and sets in the West.

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.

Night 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 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.
