What this worksheet teaches

• 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.
• Describe the main stages of digestion and where each nutrient is absorbed.

How to use this worksheet

Only about three per cent of the world's water is fresh, and most of that is frozen. Give your child that figure before the water-cycle questions - it reframes the conservation answers from slogans into arithmetic.

Sample questions from this worksheet

1. Rainwater harvesting means:
2. The sun helps water to:

Frequently asked questions

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.

Should answers be written in full paragraphs?

For the 'explain' and 'suggest' questions, yes - two or three sentences with a reason. Labelling and matching questions can stay short.
