Glad you asked...
We all know that the water cycle involves evaporation, condensation, and precipitation. However, if you have a small empty aquarium and a desk lamp, you can create a miniature model of the earth's water cycle. Full lesson plan available here: http://www.ucar.edu/learn/1_1_2_4t.htm...

Then again, this answer might help you...
Water comes from the Ocean where it evaporates to form Clouds. The Clouds eventual come down as rain, snow or hail. This water runs from creek to streams to rivers then lakes and eventually back to the Ocean. If you can draw this process then that is a model of the water cycle. If you want to be fancy, add on animals and plants and when they get the water at different stages of the cycle.
