1. WATER
CLASS VI

2. USES OF WATER DRINKING BRUSHING WASHING UTENSILS,CLOTHES,VEHICLES
CLEANING PLATES, FLOOR
PRODUCING ELECTRICITY
AGRICULTURE, GARDENING
USED IN INDUSTRIES

3. NEARLY 2/3 OF EARTH IS COVERED WITH OCEAN/SEA WATER

4. WATER IN OCEANS AND SEAS IS SALTY [SALINE] AND UNFIT FOR DRINKING , INDUSTRIAL PURPOSE AND AGRICULTURE

5. SOURCES OF FRESH WATER
1.RIVER

6. 2.SPRING

7. 3.POND

8. 4.WELL

9. 5.HAND PUMP

10. WATER IN TAPS COME FROM RIVER USUALLY

11. Cycling of water in nature- WATER CYCLE
GAS [VAPOUR]
LIQUID [WATER]
cooling
Basic processes in water cycle
1.EVAPORATION
2.CONDENSATION
evaporation
condensation
heating

12. EVAPORATION THE PROCESS OF TURNING WATER TO WATER VAPOUR BY HEATING.
WATER EVAPORATES FROM WATER BODIES AND OTHER SOURCES DUE TO SUN’S HEAT

13. THIS WATER VAPOUR JOINS THE ATMOSPHERE CONTINUOUSLY AS A SLOW PROCESS.
WATER VAPOUR ALSO REACHES THE ATMOSPHERE BY TRANSPIRATION IN PLANTS.

14. FORMATION OF CLOUDS
THE WATER VAPOUR MOVES UP AND UNDERGO COOLING , AND CONDENSATION TO FORM CLOUDS.

15. MANY TINY DROPLETS OF WATER IN THE CLOUD COME TOGETHER TO FORM LARGER DROPS WHICH ARE HEAVIER AND FALL AS RAIN.

16. CONDENSATION THE PROCESS BY WHICH WATER- VAPOUR TURNS TO WATER
ON COOLING.

17. EXCESSIVE COOLING OF WATER VAPOUR RESULTS IN SNOW FALL / HAIL

18. JOIN RIVERS LAKES AND OCEAN
THE WATER THAT FALLS ON LAND AS RAIN AND SNOW AGAIN UNDERGO CIRCULATION
RAIN WATER
SURFACE RUN OFF
JOIN RIVERS LAKES AND OCEAN
INFILTRATION
GO DEEP IN THE SOIL
SOIL WATER
USED BY PLANTS
GROUND WATER
SOUCE FOR BOREWELL

19. WATER CYCLE

20. Ground water is an important source of water

21. DEPLETION OF WATER TABLE
infiltration
Water table may go down
if the water is not sufficiantly replenished.
Consumption
of ground
water
Ground water

22. REASONS OF DEPLETION OF WATER TABLE
1. DEFORESTATION

23. 2 . SCANTY RAINFALL

24. 3.EXCESSIVE CONSUMPTION BY INCREASING POPULATION

25. DECREASE IN THE SEEPAGE AREA

26. 5. EXCESSIVE USE BY Agricultural activities

27. 6. INCREASING INDUSTRIES

28. CONSERVATION OF WATER
AVOID WASTAGE

29. CONSERVATION OF WATER
REPAIR LEAKING TAP

30. CONSERVATION OF WATER

31. CONSERVATION OF WATER
REUSE /RECYCLE
IF POSSIBLE

32. WATER WISE HABITS
DIRECT
USED
KITCHEN WATER TO
YOUR GARDEN .

33. Drip irrigation for your garden

34. WATER WISE HABITS WASH VESSELS USING COLLECTED WATER
INSTEAD OF WASHING DIRECTLY UNDER TAP.

35. WATER WISE HABITS
MOP THE FLOOR INSTEAD OF WASHING

36. WATER WISE HABITS
TURN OFF TAP WHILE BRUSHING

37. ROOF TOP RAINWATER HARVESTING
RAINWATER IS COLLECTED FROM THE ROOF OF BUILDINGS AND STORED IN TANKS AFTER FILTRATION.

38. Roof top rainwater harvesting

39. SURFACE RUN OFF
WATER PERCOLATION

40. PLANTING VEGETATION

41. Roof to rainwater harvesting

42. POND- A TRADITIONAL WAY OF COLLECTING WATER

43. INFILTRATION PITS
IT SOAKS WATER & DIRECT IT TO UNDER GROUND TO RECHARGE GROUND WATER
Pit filled with gravel

44. GRASSY PATCHES & OTHER VEGETATIONS
HELPS IN INFILTRATION

45. DRIP IRRIGATION - saves water
A TECHNIQUE OF WATERING PLANTS BY USING NARROW TUBES WHICH SUPPLY WATER AT THE BASE OF PLANTS AS TINY DROPS.

46. DRIP IRRIGATION

47. IF IT RAINS HEAVILY---CAUSES FLOOD

48. NO RAIN FOR A LONG PERIOD –CAUSES DRAUGHT

50. Save every drop of water !

51. SAVE WATER ! SAVE LIFE !

52. SAVE WATER ! SAVE LIFE !
