Technology has helped humans overcome natural limitations and improve quality of life. As populations grew, technology advanced to help humans communicate over long distances, farm more efficiently, travel via land, water and air, and build stronger structures like houses and bridges. Overall, technological developments have transformed how humans live and made the world a more comfortable place.

2.  Technology is important in
everyday life.
 Imagine what will happen in our
life without technology.
 Look at some examples of
techonology shown.

3.  There are limitations to what
humans can do.
 We cannot hear or see things which
are tiny, too soft or well-hidden.

4.  We cannot fly or walk very fast or
too far without the aid of
technology.

5.  However, humans are able to
overcome their limitations.
 Devices are used to overcome the
limitation and problems faced by
humans.

7. Telephone Megaphone Microphone

8.  Night vision goggles can be used
to see humans in the dark.
 X-ray allows us to see what is in
the body.
 Metal detectors detect objects
below the ground.

10.  Humans develop technology for
the betterment of mankind.
 This development has made the
world a better and more
comfortable place to live in.

11.  A long time ago, simple devices
were used to dig holes, and
loosen the soil.

12.  When humans discovered metal,
they invented devices to plant
crops.
 Later, animals were used to
plough the land.

13.  As the population increases, humans
need to plant more crops. Work need
to be done more quickly.
 Tracators were invented to replace the
work done by humans and animals.

15.  How did humans send messages a
long time ago?
Drawing Beating drums Smoke signal

16.  Telegraph and other devices being used
to communicate with each other in far
away places. Today, these devices are
known as telecommunication technology.

21.  Besides land transport. humans also
develop better and faster water and
air transport.
 These devices shorten the travelling
time. They allow humans to travel to
far away places.

23.  A long time ago, humans lived in
caves and built houses from clay and
parts of plants.
 However, these shelters were not safe.
They were not strong and were easily
destroyed.

24.  Today, most houses are built
using bricks, concrete and steel.
These materials are stronger.

25.  Humans are now
able to build bigger
and taller buildings.

26.  The construction of bridges has
undergone many changes.
