The Water Cycle

To help to further our understandings of 'The Water Cycle' we went out into the sandpit to create it.
We imagined that........
the sun had heated up the water so that it went up into the sky and turned into a gas called vapour (evaporation).
The vapour became colder and the air could not hold anymore vapour, so the vapour was turned into fog, mist or clouds (condensation). We pretended that polystyrene cups with holes in them were the clouds.
The clouds became dark and heavy and we saw the water return back to the land as rain (precipitation).
Some of the water soaked into the ground/sand for the plants and animals to drink (ground water).
We saw that most of the water formed small creeks and streams in the mountains (surface runoff).
We noticed that the water continued to flow and collected in the rivers and the oceans (collection).
The water was returned to the land by precipitation.

The water formed small creeks or streams.

The water collected in rivers, lakes or oceans.
