Water Cycle Demonstration

We have been learning a lot about the water cycle.
Today we did our own water cycle demonstration.
We half filled a cup with water, and marked the level on the cup.
We covered this with cling film and left it on the radiator.
We hoped that some of the water would evaporate, that the water vapour would hit the cling film and would condense into water droplets, and that it would fall again as drops of water (precipitation).
We left the water on the radiator, and by home time we could see the water cycle in action.
We were very impressed!
