Water investigations and the Water Cycle

We have been learning a lot about water (and water pollution, weather and the water cycle).
Today we did some water investigations and some water demonstrations.
First of all we did a 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!
