Try it with your learner
1. Gather a clean plastic bottle and cut it in half. 2. Place a large piece of cloth or coffee filter at the neck of the bottle. 3. In a bowl, mix 1 cup of muddy water with small pebbles and a few leaves. 4. Pour the muddy water slowly through the cloth in the bottle. 5. Observe what happens as the water filters through. 6. Collect the clean water in a separate container — can you see the difference?
