• Explain how a balanced diet changes with age, activity level and health condition.

How to use this worksheet

Sample questions from this worksheet

Frequently asked questions

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.

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.
