Water pollution is an issue in many parts of Vietnam, so we aimed to introduce a way to make mini water filtration tools for kindergarten students to get to know about the importance of clean water. We used easy-to-find and low-cost / no-cost materials including recycled plastic bottles, porous cloth, clean cotton, fine sand, and pebbles to conduct our experiment. Students were instructed to justify and make final decisions on the order of materials used as well as on the amount of each ingredient needed to construct the water filtering tool. When working in groups, they could confidently take on tasks and support each other. They were very eager to wait for every drop of clean water to flow down the water catcher and shouted out happily when their task was completed. Students could also learn a valuable lesson, thinking carefully before taking action when pouring water too quickly and forcefully causing water to spill out.
