Introduce the Topic: Water & Me
Water - where does it come from and why do we need it?
Familiarise the children with the topic by discussing as a group how
we use water and why we need it.
Some of the prompts for discussion can include:
w Talking about the importance of water for our health and hygiene.
w We drink it to keep our bodies hydrated and healthy
w We use it when we brush our teeth
w We use it to ush the toilet to keep it clean
w We have a bath and shower to wash our bodies
w We wash our clothes and dishes in it
Interactive 1
Using discussion and pictures talk about how water is used by people
around the world, animals and plants for survival, shelter, hygiene,
play. Ask the children to name some of the ways they use water at
home?
Classroom Activity:WE ALL USE WATER
Create a wall display by grouping pictures of living
things according to how they use water - aquatic
animals (shelter), plants (to grow), people (drinking,
washing, toilets, playing) etc.

The Water Cycle
Where does our water come from?
Talk about what happens when it rains and give a brief explanation of the water cycle
using the key words - evaporation, condensation and precipitation.
The Hastings water journey begins in the catchment when the clouds
burst and the rain falls.
The rainwater ows directly into the creeks and rivers and also soaks
into the earth creating ground water. The ground water trickles into the
creeks and rivers and helps to keep them owing, even during times of
drought.
The Hastings catchment stretches from the Mount Seaview Range
down the Hastings Valley through pockets of untouched forest, acrossour rural landscapes and through towns on its journey to the sea.

EvaporationEvaporation is when the sun heats up water in rivers or lakes or the
ocean and turns it into vapour or steam. The water vapour or steam
leaves the river, lake or ocean and goes into the air.
CondensationWater vapour in the air gets cold and changes back into liquid,
forming clouds.
Precipitation (Rain)Precipitation occurs when so much water has condensed that the air
cannot hold it anymore. The clouds get heavy and water falls back to
the earth in the form of rain, hail, sleet or snow.
Water - every living thing needs it to survive.
Water has been lling the clouds and falling back to
the Earth again as rain for millions of years. This is
called the water cycle.
There is no more water on the Earth today than therewas when life on Earth rst began. In fact, the water
we use today is the same water the dinosaurs drank.
Of all the water on Earth only 1% of it is fresh water
that is available for us to use. Around 97% is salt water
and another 2% is locked in ice caps and glaciers.
In the Hastings, the water journey begins when the
clouds burst and the rain falls.
The rain ows into the creeks and rivers and also
soaks into the earth creating ground water.The ground water trickles into the creeks and rivers
and helps to keep them owing, even during times of
drought.

WATER CYCLE ACTIVITIES
What you need - kettle, mirror
To demonstrate visually how the water cycle works, boil a
kettle and allow the steam to condense on the surface of a
mirror held above.
Explain that the kettle is a river, and when the sun heats up
the water it begins to evaporate.
The steam represents the water particles rising into the sky
(the mirror). The water then cools in the sky and turns back
into a liquid which is held in the clouds.
Explain how the clouds become so heavy with water, they
burst open and rain falls from the sky (as the droplets begin to
fall from the surface of the mirror).
The water then falls back to Earth, and the cycle starts again.
Misty Mirrors
Pour a puddle of water on to a sunny area
of concrete or a at surface and draw a
line around it with chalk.
Monitor the puddle and watch as the
water shrinks away from the sides of the
chalk and disappears.
When the water has evaporated, discuss
how heat causes evaporation and what
happens to water particles during this
process.

From Catchment to Tap
Discuss water storage and the journey from the dam to the
preschool tap. Where does the water come from when we turn
on the tap?
Explain how the dam lls up when it rains, and empties every
time we use water at home and preschool.
Show pictures of the Port Macquarie and Cowarra off-creek storage dams and
explain the journey of Whizzy the Waterdrop from a rain cloud, to our river, from
the pump station to the treatment plant, from the dam to our water reservoirs
and then through the pipes to our taps at home.

Outdoor Activity: PLAYGROUND PIPELINES
How does the water get from the river to our houses?
We worked together to find out.
1. Mason and Domi made a
river that led to our pumping
station.
We used blue cellophane as
water.
2. Dylan and Declan dug out thedam. The clean water is
pumped to the dam from the
pumping station.
Bronte and Declan laid down
our cellophane water in our
dam.
3. Kaleb, Dylan and James dug
out some sand ready for our
next pipes to be laid.
4. Elli laid down the pipes that
take the water from the dam to
the reservoir.
5. Eloise put in our reservoir
which stores our water ready to
use.
6. Eyria and Declan dug out
some room for the new pipes
which were laid by Zach!
These pipes will take our water
to our houses.
Now that we have finished,
Aidan and Jack can have adrink!

Print out pictures of a river, the ocean, the
sun, clouds, rain. Additionally you can print out
pictures of a dam, a reservoir, water pipes and atap.
Jumble up the pictures and ask the children if
they can sort them in order of the water cycle
and then how water travels from the river to the
tap.
When they have the pictures in order, discuss
the journey of a water drop from the momentit rains to when a tap is turned on at home.

Making a Water Cycle
First Jack put in the rocks Then Siena added the sand
Ashton put in the soil for the plants Kaelan planted one plant
Then Ben planted the 2nd plantWe needed to add water so we can
watch the water cycle
We also needed to put the lid onto create the sky
We placed our cycle in the sun and
will observe it over the next few days towatch the evaporation, condensation
and precipitation.

This experiment is designed to
highlight the effects of filtration on
the cleanliness of our water supply.
MATERIALS:
Clear jars
Soil
Sand
Cheese cloth
or cotton cloth
Rubber bands
What To Do:
x Pour water into a clear jar
x Add some soil and stir
x Observe the clarity of the water
x Spread cloth over opening of another large jar. Hold in place with a
rubber band.
x Poor sand over top of cloth.
x Slowly poor the water with the soil through the sand and into the
clean jarx The water poured through the sand should be cleaner
than the water in the original jar.

EXPERIMENT: HOW DO CLOUDS WORK?
x Each child was given a cloud (cotton
ball) and asked how it felt soft,
light, fluffy, smooth.
x Trays were filled with water to
represent a river.
x We placed the clouds into the water
and watched as the clouds filled with
water and became... cold, wet,
filled up, heavy.
x When the cloud was picked up out of
the water it was dripping. rain!
We discovered.x Evaporated water fills up the clouds.
x When the clouds get heavy with water it RAINS!x Water falls back into the rivers, streams, oceans and onto the ground for the
process to begin again.

Today we observed in a hands-on experiment the process of EVAPORATION!We joined with the Orange room to create our own water source the water puddle area
outside. We added some water to this and marked the boundaries with blue chalk so we
could see where the water line began.
FACT: Evaporation is when water changes from liquid to vapour. Evaporation
causes clothes to dry on the washing line and puddles to dry up after rain.
The empty puddle is filled with water and
marked for reference.
The children were very keen to see the
change in water level.
They kept checking the water puddle
for the change in level.
It slowly began to disappear!

Learning About the Water Cycle
Today we began to talk about Whizzy the Water
Drop and the water cycle. I asked the children
where does water come from... Rain, rain drops,tap, sea, waterfalls, lakes, ice, dams and clouds
Why do we need water? The children responded
So we can stay alive, to drink so we dont get
dehydrated, so we can keep our bodies still, for
baths, it makes you healthy, for showers, to water
our plants, to grow vegetables, to swim, for
animals
We learnt about the
water cycle and how
the sun heats water,
which rises and
forms clouds, as they
get heavy it falls as
rain.
During music we
were sailors
climbing the
mast and
crossing the
ropes.
We then did a
science experiment
to show the children
visually the water
cycle. The kettle was
the lake, the heat the
sun.
We enjoyed Row
Row Row Your
Boat with a
friend.
The children were
amazed when the
steam started to rise
showing evaporation.
The mirror was the
sky and as the
droplets formed it
began to rain.
And we sang
about rain, I
Hear Thunder
and Rain Is
Falling Down
