Students are challenged to engineer an effective water filtration system that will assist victims of natural disasters. They will investigate the hydrologic cycle, the effects natural disasters and contaminated water have on living organisms, and compare the body systems of various organisms while testing the effectiveness of their team’s filtration system. After filtering contaminated water, they observe the hydrologic cycle’s natural ability to purify water by distilling their filtered water. Testing for particulate matter, bacteria, and turbidity are performed in order to observe comparisons between the contaminated water sample, the filtered water sample, and the distilled water sample.
