SCIENCE AND TECHNOLOGY
The world we live in is
changing fast! For example, modern houses are
different from
traditional
ones.
They
are
made
of
new
materials
such
as
concrete,
iron
and
glass
instead
of natural materials such as stone, wood and
leaves.
Inside a modern house
we
find
electric
lights,
refrigerators,
gas
cookers,
radios,
television
sets
-
perhaps
even computers. People are usually much
healthier than they used to be. We expect to
live longer than our ancestors. Many of
us wear new kinds of clothes, made from new
kinds of cloth. We eat different foods
from our ancestors, and prepare them differently.
We
also
travel
further
and
faster
than
they
did.
They
walked,
or
rode
an
animal,
or
paddled a canoe. Now we use a bicycle,
a car, a truck or a motorboat. There are also
much larger vehicles that carry many
people and move huge loads. We can fly long
distances
at
great
speeds
in
aeroplanes.
We
can
pick
up
a
telephone
and
speak
to
people
who are far away.
And we learn about
important events all over the world, as
they
are
happening,
by
listening
to
the
radio,
watching
television
or
'going
on
the
internet'.
In
some
places,
changes
like
these
started
long
ago
and
happened
very
slowly. In other places, change is much
more recent and has happened very
quickly.
Traditional life
Modern life
When our
grandparents were young, it would have been
difficult for them to imagine
some of
the marvels of the modern world. What has caused
all these amazing changes?
The
answer
is
science
and
technology!
Science
is
a
method
used
by
people
called
scientists to find out about the world
around us. Science also refers to the
knowledge
that
scientists
have
obtained.
Technology
is
how
we
apply
our
knowledge
and
experience to make things and do things
that are useful to us.
