STEM Water Filtration from students in Year 4 and Year 5 Int’g
The Central part of Vietnam has been inundated with heavy rain due to typhoons hitting this area of the country very severely. Water resources have become polluted because of the extremely high rain totals and the combination of floods and mudslides have led to waters polluted with open sewer waste, dead animals, mud and debris. This has led to a large shortage of clean water and a very serious problem for this part of the Vietnam. In our STEM classes we have studied together ways in which to build a Recycled Water Filtration System Model. Through this process we have come to understand the difference between filtration and water treatment. We studied and experimented on how thickness of filter paper, sand, and coal affects the way in which impurities can be removed from polluted water. Through this enjoyable STEM experiment, we have found that studying science with friends can build our self-confidence enough to allow us to make presentations to large groups of our classmates.
