3. Identify differences between clean water and dirty water by looking at them.

Presentation Steps

1. Introduction: Ask pupils what they use to brush their teeth or quench their thirst. Introduce **water** as a vital liquid necessary for all life.
2. Sources of Water: Brainstorm where we get water. List them out: Rain from the sky, rivers/streams, deep wells, modern boreholes, and house taps.
3. Uses of Water: Talk about home and school routines: drinking, cooking food, bathing, washing school uniforms, washing dirty dishes, and watering garden flowers.
4. Clean vs. Dirty Water Comparison: Place the clean cup next to the muddy cup.
