SIMPLE MACHINES
Machines help us to save time and
energy. They make work easier.
Machines with no or few moving parts
are called SIMPLE MACHINES.
Some examples:

THE PHASES OF THE MOON
The Moon is a non-luminous body like
the Earth. It reflects light from the Sun.
We can only see the part of the Moon
that is illuminated by the Sun. This is why the Moon seems to change shape at
different times of the month.
THE SEASONS
The Earth orbits the Sun. This
causes the four seasons.
In the Northern Hemisphere the seasons
are:
THE EARTH´S MOVEMENTS
ROTATION: The Earth continually rotates on its axis. It takes 24 hours, or one day, to make one
complete rotation.
This movement
causes day and night.
The Earth rotates anticlockwise on its axis. This means
the Sun rises in the east and sets
in the west.
THE EARTH
To study the Earth, we can use world
maps. They show that most of the Earth´s surface is covered in water. The rest
of the Earth consists of large masses of land separated by oceans, called
continents.
There are six continents: Africa, America, Asia, Europe, Oceania and Antarctica.
