The STEM Central Context on Water allows practitioners and learners to explore Cleaning Water. The cleaning water learning journey has a Sciences focus, aimed at third level. Learners are asked to reflect on the different ways in which water can become polluted and on the importance to humans of a safe, clean water supply. They are then given a scenario and a brief for analysing raw water. Learners explore a range of techniques for physically separating mixtures into their components in relation to the context of cleaning water.

The Glow Science (Glow log in required) video on Water Pollution allows you to discover what water pollution means for the environment and how it affects humans.
