The Water Cycle

As part of our school wide inquiry around time, some of the classes have been discussing the water cycle.
Is water finite?
Is the water on our planet today, the same water that was around when the dinosaurs walked?
These questions sparked great discussion and explanations of thinking.  Once we started to talk about the water cycle, some boys ideas began to change!  We've learnt scientific explanations for evaporation, condensation and precipatation.  We've also talked about transpiration, sublimation and groundwater storage.
To reinforce our learning, the boys got into groups and created their very own water cycle.
