SPLASH!!!!!! Are your getting spalshed with water or dirt??????

SPLASH!!!!! In a class experiment today in school we learned about the water cycle. In this experiment we each had a part in the cycle. Most people were a spoon, which represented evaporation and condensation, their job was to take water from one reservoir to another. On the other hand, others were walking around with cups as clouds. The clouds would walk around the room and if a spoon intersected with a cloud before it meets its destination then the spoon would have to pour the water in it into the cloud, or cup. When the cups were filled to the top they would return to the ocean and rain down and then start over again. For the reservoirs we used tanks filled with water, some like the ocean, aquifer, streams and lakes. After we imitated the water cycle we saw that the reservoirs did not differ very much since the begin of the experiment. The scientist explained that this was a balanced cycle, but was this true, No! We now moved on to part two of the experiment, the truth. In this part of the experiment, we now added to other main people to see the human influence on the water cycle. To see the human influence we added a couple people with bigger cups representing our taking of the water and added two of the reservoirs with blue food coloring and one empty in which the people with the bigger cups would then fill. The food coloring represented the pollution. After round two we settled in to see the results. It was shocking! We saw that most of the reservoirs were empty, but the little water left was blue. On the other hand, the empty tank that the people with bigger cups filled was overflowing. after a nice long clean up we discussed the results. Although, this experiment is not exact to the amount of polluted water, this experiment showed the general idea of what we do to the water cycle. Do we really pollute this much?
