Common misconception
Children may think that everyone has access to safe drinking water, and that water just 'appears' clean from a tap.
This lesson explains how approximately 1.6 billion people in the world today do not have access to water that is safe to drink. Also, that water is usually filtered and treated to make it safe to drink.
Equipment
Plastic bottles, scissors, masking tape, cotton wool, sand, gravel, soil, 'dirty water' sample.
