The “portrait”
of the water cycle
R
emarkably, ever since water first appeared on
Earth, it is in a ceaseless state of motion, yet its
quantity has been more or less stable. Little has been
added or lost over millions of years.
Water evaporates. It travels into the air and becomes
part of a cloud. It falls down to earth as precipitation;
then evaporates again. This procedure repeats itself
in a never-ending cycle. Water keeps moving and
changing from solid to liquid to gas, over and over
again.

Let’s draw the water cycle!
Materials/Equipment
-
(( 3a
paints or coloured markers
2 sheets of cardboard
a pair of scissors
pins
Procedure
1. Use one sheet of cardboard to make nine labels
and write the following keywords of the
hydrological cycle in each one of them.
Ice
Precipitation
Ocean storage Evaporation
River flow
Evapotranspiration
Groundwater
Percolation
Lake storage
2. Use the second sheet to draw the hydrological
cycle. Try to include all nine keywords.
3. Pin the labels on the appropriate possition on
your drawing and connect them with arrows.
4. As you walk around your community identify
elements of the water cycle that you see. Use a
camera to capture water pathways.
5. Organise a photography competition on the water
cycle and set up an exhibition.

of water may once
have been drunk by
a dinosaur?
