Water Cycle Demonstration

The water cycle is a natural cycle that purifies water. It is the evaporation of water into the air which will then travel to other natural water reservoirs such as lakes and clouds. In the first part of the demonstration some kids were given cups that said cloud and others got plastic spoons. The ones with plastic spoons were to take water from a certain reservoir and go to another. As a cloud you had to take water from the plastic spoons who represented evaporation. When clouds got full you dumped the water into the reservoir you were assigned to. After this a reservoir got extremely low while others were filled and some not changed. Then humans were added and at the rate humans took water they would be flooded soon. Finally, pollution was added. By the time the demonstration was over almost all of the reservoirs had pollution in it while some had barley any water left. Again the humans were flooded with pollution. This activity showed how the water cycle should always be balanced or there will be consequences.
