HOW DO WE USE AIR AND WATER?
How do we get the water to our houses?
AQUEDUCTS
Pipes that carry water to where we need it.
RESERVOIRS
People build a DAM across the river.
The collected water is called a reservoir.
The high dam in Aswan
WELLS
We dig holes to pump upunderground water.
WATER TREATMENT
Making water safe for us to drink.
STEP 1: WATER SITS STILL IN A TANK
Heavy things in the water fall to the bottom of the tank.
STEP 2: WATER IS MOVED TO LAYERS OF GRAVEL & SAND
These layers catch the mud and other tiny things.
STEP 3: CHEMICALS ARE ADDED
To kill any harmful things in the water
Chlorine is added to kill the germs and bacteria.
