What this worksheet teaches

• Explain the water cycle and connect it to the availability of fresh water for drinking.
• Evaluate water purification methods - sedimentation, filtration, chlorination, boiling, RO - by what each removes.
• Analyse causes of water pollution and propose realistic community-level solutions.
• Explain how a balanced diet changes with age, activity level and health condition.

How to use this worksheet

Grade 5 answers are judged on reasoning, not recall, so push for the 'because' on every question. 'Chlorination is used because it kills germs but does not remove mud' is a Grade 5 answer; 'chlorination cleans water' is a Grade 3 one.

Sample questions from this worksheet

1. Water pollution is caused by:
2. Which device filters water at home?

Frequently asked questions

Is a diagram expected for the water cycle?

A labelled sketch with evaporation, condensation, precipitation and collection is a strong answer at Grade 5 and usually earns full credit.

How is this different from the Grade 4 food chapter?

Grade 4 identifies nutrients and preservation methods; Grade 5 explains processes - digestion and absorption, the water cycle, why each purification method suits a particular impurity, and pollution analysis.

Does RO water need boiling too?

Generally no, since reverse osmosis removes both dissolved impurities and most microbes. The worksheet asks this to test whether a child can match a method to the impurity it targets.
