How do we use air & water
1.
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.
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
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
