Study of water pollution and filtration experiment (dirty water, oil) Understand the importance of water quality Analysis; Research Filtration – NG Kids

This teaching guide outlines a hands-on water filtration experiment designed to engage students in understanding the importance of clean water and the impact of pollution. It begins with the necessary materials, which include clear bottles, dirty water, oil, coffee filters, sand, and gravel. The preparation of 'polluted water' helps simulate real-world water contamination scenarios. Students will perform observations before and after filtration, making predictions about the effectiveness of different materials in cleaning water. The lesson emphasizes the significance of water in daily life, the types of pollutants encountered, and provides interactive components like an opinion poll on water safety. Through group work, students assume specific roles to execute the filtration experiment safely, fostering collaboration while learning about water pollution and filtration processes. Reflection questions at the end encourage critical thinking about the health impacts of unclean water.
