Lesson Plan of Evaporation as well as Condensation
General Science Grade V
Students’ Learning Outcomes
· Describe the move of evaporation as well as condensation inwards the H2O cycle.
· Identify as well as depict forms of wet inwards the environment.
(e. g. dew, snow, fog, frost as well as rain)
Information for Teachers
· When a liquid similar H2O is kept inwards an opened upwards container, its particles continuously deed from liquid stage to air. This procedure is called evaporation as well as it continues at all temperatures.
· During nighttime when the temperature of air falls, the H2O vapours introduce inwards air teach together as well as shape droplets of water. The procedure is called condensation.
· It forms when the temperature of an object drops below the dew dot temperature. ... Frost: the H2O ice crystals formed past times deposition of H2O vapor on a relatively mutual depression temperature ... over marshy areas or soil saturated past times a recent heavy rainfall or rapid snowmelt. ... humid air flows over relatively cold, snow-covered Earth inwards early on spring, ...

Worm upwards Activity
Ask the students:
· You must receive got seen your woman nurture spreading laundry inwards the opened upwards air. After to a greater extent than or less fourth dimension the wearing clothing teach dry. Where does the H2O become from the wet clothes? ( Students’ response: it evaporates inwards the presence of sunlight)
· Ask students receive got y'all been to a nearby garden early on inwards the morning. Why does the grass experience wet? (Students’ response: The grass is wet due to early on morn dew)
· Draw this diagram on the board as well as explicate both the processes.

Development
Activity 1
· Take H2O inwards a bowl. Draw a trouble inwards the bowl to quest the marker of water.
· Ask a pupil to maintain the bowl inwards the sunlight.
· After to a greater extent than or less fourth dimension enquire the pupil to convey the bowl dorsum inwards the classroom.
· Let all the students divulge the marker of H2O inwards the pond.
· Ask the students the next questions:
-----What modify has occurred inwards the marker of H2O inwards the bowl?
( Students’ response: It has lowered)
------Where does the H2O from bowl go?
(Students’ response: It has changed into Vapours due to oestrus of the Sun)
· Explain that little drops inwards the air are called H2O vapours. They are non visible.
Activity 2
· Take a stainless steel drinking glass wipe its outer surface amongst dry out cloth. Add to a greater extent than or less H2O ice cubes into it.
· After to a greater extent than or less fourth dimension permit the students divulge the outer surface of the glass.
· Ask students the next questions:
-----What has appeared on the outer surface of glass?
(Students’ response: Small droplets of H2O appear on the outer surface of glass.)
------Where these droplets receive got come upwards from?
(Students’ response: Water vapours introduce inwards air, on touching the mutual depression temperature surface of glass,
get together to shape droplets. This procedure is called condensation)
· Teacher volition inform the students that when H2O vapours attain upper atmosphere they condense due to depression temperature as well as shape clouds. Clouds drive rain.
· Ask students to cite the original sources of H2O inwards the world?
(Students response: Sea, Lakes, Rivers, Ponds, Oceans & atmosphere.
· Inform students that all these reservoirs are called H2O bodies.
Water moves continuously through each of the H2O bodies past times the processes of evaporation as well as condensation as well as the phenomenon is called H2O cycle.
· The transfer of H2O mainly from oceans as well as other H2O bodies to the atmosphere takes house through evaporation. Most H2O vapours supply to the oceans, patch to a greater extent than or less vapours are carried past times air current to unlike areas of land.
· Here the vapours condense due to depression temperature as well as autumn dorsum on earth inwards the shape of rain, snowfall as well as hail as well as sometimes inwards the shape of dew as well as fog.
· During wintertime when the morn temperature is real low, drops of H2O condense as well as suspend inwards the atmosphere equally fog.
· In intense mutual depression temperature days these H2O droplets autumn downwardly equally frost. This is the agency nature distributes H2O throughout the province for our daily use.

Sum upwards / Conclusion
· Water moves continuously through unlike H2O bodies introduce on the earth past times the processes of the evaporation as well as condensation as well as the phenomenon is called H2O cycle.
· Early inwards the morn as well as at nighttime H2O vapours condense together to shape droplets as well as come upwards downwardly on earth equally dew or suspend inwards the atmosphere equally fog. This procedure is called condensation.
Assessment
· Ask students the next questions:
---How clouds are formed?
(Students response: Water vapours coming from body of body of water rising upwards inwards the cooler part of the
Atmosphere. Here they condense to shape clouds)
---What is the deviation betwixt pelting as well as dew?
(Students response: Water vapours introduce inwards clouds condense together due to depression temperature at high altitude).
· Under favorable status this condensation causes H2O to precipitate equally rain. At nighttime or early on inwards the morn H2O vapours introduce inwards air condense together to shape little droplets. These droplets thence autumn downwardly equally dew)
----How is H2O introduce inwards oceans distributed throughout the province on earth?
( Students response: Wind carries vapours introduce to a higher house the oceans to far off places on earth,
where they teach together at cooler places to shape clouds. These clouds thence drive pelting as well as
water is distributed throughout the province on earth)
· Involve the students inwards solving the questions given at the terminate of chapter / unit of measurement of textbook,
Follow up
Ask the students to write answer to the next questions:
-----While taking a bath during wintertime amongst hot H2O what exercise y'all divulge inwards a bathroom?
(Students response: During bath hot H2O evaporate to shape fog inwards the bath room)
-----At which times, at that topographic point is maximum possibility of the formation of dew or fog.
(Students response: Early inwards the morn or during nighttime the temperature of the
atmosphere
As fog. Alternatively heavy droplets of H2O autumn downwardly inwards the shape of dew)
------What is the cite of the procedure inwards which H2O vapours are converted into liquid H2O ?
(Students’ response: condensation)
