Natural resources like air, water, plants, and animals are found in nature and used by people to survive. There are two types of water resources: fresh water from sources like rivers and lakes that is used for drinking, and salt water like oceans that is not potable. Fresh water is transported to homes through aqueducts, stored in reservoirs, or accessed from underground wells. Water is treated before human consumption by allowing impurities to settle, filtering through sand and gravel, using chemicals to kill harmful organisms, and pumping the clean water to the population.

2.  A natural resource is something that is found
in nature and can be used by people.
 Some examples are: Air, water, plants,
animals, and soil.
 People use these natural resources to stay
alive.

3.  Water is an important resource.
 People use water for drinking, farming &
cooking.

4.  People also swim, fish & play in water too.

5. Can we drink from the water which we swim in?
- Of course not, because they are different types of water.

6.  We have two types of water resources:
1) Fresh water resources: The type of water
used for drinking.
2) Salt water resources: The type of water
which is not used for drinking.
Water resources

7.  It’s found in rivers, ponds, lakes & streams.

8.  Glaciers, Ice bergs & Sea ice are also examples
of fresh water although this water is frozen.

9.  Also “ground water” water that is held in
rocks below the ground is a kind of fresh
water.

10.  This kind of water is not used for drinking.
 Most of the earth’s water is salty water like:
Oceans & Seas.

11. Mum, How do we
get the water we
drink from the
rivers to our home?
Well, water gets
to us through
many ways, let’s
see

12. How do people get water?
Aqueducts Reservoirs Wells

13.  They are pipes that carry water to where it is
needed.
Aqueducts

14.  In some places, people build a wall “Dam”
across a river & water gathers behind it.
Reservoirs

15.  They are deep holes that people dig to reach
the underground water.
 These wells are filled with the underground
water & then we pump it out.
Wells

16. Do you think we can drink water directly from the river?
Of course not, As this water is not clean yet

17. Treating water
To treat water, is to make water safe & clean
for people to drink
Water from rivers & lakes may contain very harmful
materials, that’s why we have to clean water & treat it first
before we drink it

18. Step (1):
Water sit still in a tank, so heavy
things in the water fall in the
bottom of the tank.
Steps of treating water

19. Step (2):
Water move to layers of sand &
gravel, these layers trap mud &
tiny things

20. Step (3):
Then chemicals are added to kill
any harmful things in the water

21. Step (4):
Clean water is then pumped to
people

30. - Water pollution happens when harmful things
get into water.
- Pollution makes living things sick.
Water pollution

31. Types of pollution
Natural pollution Man – made pollution
Happens naturally
Happens because of
people

32. - Rain washes pollutants “like: dust”
from air & land into the water.
Natural pollution

33. - People use fertilizers to help plants to grow.
- These fertilizers soak into the ground &
pollute ground water.
Man-made pollution

34.  Conserving resources is to
use resources wisely, so
they can last for a longer
time.
Conserving resources

35. Ride your bicycle instead of the car whenever you can.
This can conserve fossil fuels

36. Turn down the heater & wear a sweater, if it’s cold.
This can conserve fossil fuels

37. Turn off the lights when leaving a room.
This can conserve fossil fuels

38. Turn off the water tap while brushing your teeth.
This can conserve water

39. Plant trees & other plants.
This can protect the soil & helps put oxygen back to the air

40. This can protect land & water
Dispose your trash & chemicals properly.
