Tips
To deepen understanding of water filtration, introduce hands-on activities where children create their own simple water filters using household materials like coffee filters, sand, and activated charcoal. Discuss the water cycle to contextualize how water moves and gets naturally filtered in the environment. Expand the lesson to include discussions on how water pollution affects ecosystems and people, encouraging empathy and awareness. Encourage older children to research different water treatment technologies and compare their effectiveness and applications.
