Note to Pupils –
Potable Water:
Potable water is water that is safe to drink and use for other activities without causing harm. It is clean and free from harmful substances.
Contaminated Water:
Contaminated water is dirty, impure, and unsafe for drinking or daily use. It may contain harmful substances like germs and chemicals.
Evaluation:
- What is potable water?
- What is contaminated water?
- Describe a situation where you used clean water.
Note to Teachers:
Ensure that pupils understand the importance of clean, potable water and how to differentiate between clean and contaminated water samples. Customize the lesson content, teaching methods, and pupil activities to suit your teaching style, curriculum, and available resources.
