Bit of intro explanation
set the scene
and explain the task or
topic. Blah and
blah blah.
precipitation!
Pour about (5 cm) of hot water into the glass jar.
Cover the jar with the plate and wait three minutes
before you start the next step.
Put the ice cubes on the plate.
Then look into the jar to see what happens...
How does it work?

Things you
'll need:
— A glass ja
r
- A plate
- Small amo
water ( be ucnt of hot
- Ice cubes areful)
This is a mini version of what happens in the atmosphere.
The cold plate causes the moisture in the air in the jar, to cool down and form water droplets. On Earth,
warm, moist air rises and meets colder air higher in the atmosphere. The water vapour condenses and
forms precipitation (rain) that falls to the ground. The Earth has a limited amount of water. This water
keeps going round and round in what is called the ´Water Cycle`. This cycle is going on all the time and
has four main parts:
CONDENSATION
PRECIPITATION
Warm water vapour in
the air cools and
changes back into a
liquid and forms clouds.
When so much water has
been condensed that the air
cannot hold it anymore, the
clouds become too heavy
and water starts to fall.
EVAPORATION
The sun heats up
water in rivers, lakes
and the ocean and
turns it into steam or
vapour which is then
taken into the air.
COLLECTION
Water falls as precipitation
into the rivers, lakes or
oceans that it came from, or
onto the land and is either soaked up
or used by plants, animals and man.
Then it starts the cycle all over again.
What other forms of precipitation are there
apart from rain?
What do we know about whether there is
water on other planets?
Why do you think that it snows on
mountain tops?
Cardiff is the UK’s
wettest city with an
average 115cm of
rainfall per year,
closely followed by
Glasgow (112cm) and
Preston (103cm).
How can we make sure that we don’t
waste water?
