Activity Number 4: Water Treatment
Step 1- Coagulation
Coagulation removes dirt and other particles suspended in water. Alum and other chemicals are
added to water to form tiny sticky particles called "floc" which attract the dirt particles. The
combined weight of the dirt and the alum (floc) become heavy enough to sink to the bottom
during sedimentation.
Step 2- Sedimentation
The heavy particles (floc) settle to the bottom and the clear water moves to filtration.

Step 3 - Filtration
The water passes through filters, some made of layers of
sand, gravel, and charcoal that help remove even smaller
particles.
Step 4 - Disinfection
A small amount of chlorine is added or some other
disinfection method is used to kill any bacteria or
microorganisims that may be in the water. Fluoride is
added to the water to protect your teeth. The water also
undergoes UV disinfection which is capable of
inactivating cryptosporidium.
Step 5 – Storage
Water is placed in a closed tank or reservoir in order for disinfection to take place. The
water then flows through pipes to homes and businesses in the community.
Activity Number 5. The Water Cycle.
Fill in the blanks.
A._________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.
B. Water vapour in the air gets
cold and changes back into liquid, forming clouds. This is called ___________.
You can see the same sort of thing at home... pour a glass of cold water on a hot day and watch
what happens. Water forms on the outside of the glass. That water didn't somehow leak through
the glass! It actually came from the air. Water vapour in the warm air, turns back into liquid
when it touches the cold glass.
C. _________ 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.
D. Water is __________ when water falls back to earth as precipitation, it may fall back in the
oceans, lakes or rivers or it may end up on land. When it ends up on land, it will either soak into
the earth and become part of the “ground water” that plants and animals use to drink or it may
run over the soil and collect in the oceans, lakes or rivers where the cycle starts all over again.
