1 and 2
Understandthe water cycle
that waterevaporates from oceans, seas and lakes, condenses as clouds andeventually falls as rain
that watercollects in streams and rivers and eventually finds its way to thesea
thatevaporation and condensation are processes that can bereversed
recognisethat melting, freezing, evaporation and condensing are all changeswhich can be reversed
Findexamples of the above changes
be able todescribe the water cycle.
understandwhere the processes of evaporation and condensation are involved inthe water cycle.
Play them the Evaporationsong. Ask them to pick out key words. Act out evaporation anddiscuss what is meant. Check children understand the processes ofevaporation and condensation and brainstorm everyday examples ofboth, eg. puddles drying up, washing drying, mirror. Establish thatthese 2 processes are opposite, one is reversed by the process ofthe other.
Explain that today you aregoing to demonstrate to the children how these 2 processes ensurethere is always water. Show children the Virtual Book of The WaterCycle, the adventures of a droplet of water (Dropletta). Introducethe children to the character of a water droplet. Go through thepresentation discussing what is happening in each picture andasking the children the process occurring. Hold the mouse over thepicture for a scientific explanation to appear, or read it writtenbelow the picture. As you view the last picture, ensure childrenunderstand that Dropletta is back in the sea again, ready for theprocess to repeat. Lead discussion onto an explanation of why it iscalled the water CYCLE. (TA to read through with Isra andMohammed)
Allow children to view theVirtual Book again in Talk Partners, taking it in turns to explainwhat is happening to the water and using the terms evaporation andcondensation. Children could read the explanation underneath tocheck they are right. LA: With Alex, make a big thought board ofthe water cycle.
MA/HA:Draw a diagram in your book to demonstrate thewater cycle.
Ext:Children could invent their own water dropletcharacter and invent their own story for it. Perhaps it could startlife in the bath and end up as condensation on the mirror.
Homework: LA- coloura picture book of the Water Cycle
MA/HA fill in the cloze water cycle, if you want youcould also write a story of a water droplet.
Plenary:End the lesson with a class discussion on whatthe children have found out and how important the Water Cycle is tous.
