The Egyptian Pyramids are colossal structures used by
the ancient world for religious purposes. The largest and most
remarkable of the pyramids occur in several groups on the west
side of the Nile extending for a distance of twenty five miles reaching
as far as Cairo (the capital city). The are built from hard limestone
and large blocks of limestone, especially on the outside surface. They
date from 3000 BC to 2300 BC. Great skill was needed to quarry these
large blocks, transport them and then place them in position. The
Ancient Egyptians were very well organised and they required a good
understanding of technology,
science and
mathematics to enable them to build what has become known
as one of the wonders of the ancient world.

THE THREE PYRAMIDS OF
CHEOPS (the Great Pyramid) , CHEPHREN AND MICERINUS

One of the first tasks of the pyramid builders who
constructed the three pyramids shown above, was to build a track on
which they could drag the large blocks from the quarry in the Arabian
Hills to the River Nile where they were ferried up to the construction
site. The work went on in three monthly shifts with one hundred thousand
men in a single shift. It took ten years to build the track It took the
same number of men twenty years to complete the Cheops pyramid.
Originally the pyramids were smooth on the outside but through the
thousands of years since construction this has disappeared revealing the
tiers or steps underneath. Each tier is about a metre in height.

The pyramids
we built by kings as tombs or memorials of themselves and it is thought
that they were started at the beginning of each reign and that the
height corresponded with the length of each reign.
The pyramid
of Cheops was originally 146 metres high and the technology for lifting
the blocks into position was well designed.

1. Draw a map of Egypt and mark show the location of
the city of Cairo.
2. Design a mechanical crane capable of lifting
blocks similar to the ones used to build the pyramids. Remember, the
Ancient Egyptians could only use human or animal power. Your design may
include some form of levers and pulleys.
3. Using the internet as a resource, find information
about other well known structures or buildings constructed by the
Ancient Egyptians. Write an account of some of these examples.
