· Draw the next tabular array on board together with create sum it alongside answers given past times the students.
· Now inquire the next questions from students to conclude this activity.
Colour | Smell | Transparency | Suspended Particles | |
Tap H2O | ||||
Water from pond or Stream or River |
------Which H2O volition yous similar to drink?
------What volition guide identify if H2O of both beakers is mixed?
------If yous potable mixed water, volition it stimulate whatsoever disease?
------Name some diseases which may spread if the polluted H2O is used for drinking purpose?
(Expected Ans: Typhoid, Cholera together with dysentery)
Activity 2
Divide students into groups together with instruct them for the next activity:
· Spread crude jelly on 3 evidently papers alongside the assistance of a plastic knife.
· Attach 1 paper to a clipboard together with identify it outside.
· Place 1 paper inwards the classroom nether the teachers’ desk.
· Place 1 paper close window inwards the classroom.
· After a twenty-four hr menses or 2 compare the papers to run into how pollution has effected the crude jelly placed at the dissimilar locations.
· Ask students which paper has the greatest outcome of pollution? What does it show?
· Conclude the results through thinking together with predictions. Explain the effects of air pollution.
Activity 3
· Divide students into groups together with instruct them for the next activity:
· Take 2 jars together with labels 1 every bit “water” together with create sum it alongside evidently tap water.
· Label the 2d jolt “acid water” together with create sum it alongside one-half vinegar together with one-half tap water.
· Dip 4 leaves completely inwards each of the jars.
· Observe the leaves afterward a few days together with tape your observations.
· Ask students what is the outcome of acid H2O on leaves? What does it show?
· Conclude the results through thinking together with predictions together with explicate the effects of air pollution (acid rain)

Use of fertilizers together with pesticides | |||
Sewage water | |||
Garbage waste | |||
Industrial waste | |||
Cutting trees | |||
Burning of plastic |
Sum upwardly / Conclusion
· Water may incorporate bacteria causing cholera, typhoid, diarrhea together with dysentery.
· Sewage H2O produces bad aroma due to 2 gases i. e. ammonia together with hydrogen sulphide.
· Smoke from chimneys causes acid pelting together with diseases of lungs, pare together with eyes.
· Burning of garbage / plastics produces poisonous gases which are lethal for humans, animals together with plants.

· Pollution may disturb the natural nutrient chain. How?
· Sometimes when yous give-up the ghost out, in that location is fog inwards wintertime together with things are non visible. Why?
· Sometimes, afterward rain, the hush-hush H2O becomes polluted. Why?
Ask students to rewrite the next statements afterward making corrections.
1. Human beings stimulate air pollution past times using electricity.
2. When corporation waste materials is dumped (underground), it provides dwelling for affliction carrying animals such every bit rabbits together with rats.
Follow up
Ask students to bear a pollution awareness Campaign: Ask them to:
· Make a view roughly their homes.
