What this worksheet teaches

• Compare food adulteration examples and simple home tests used to detect them.
• 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.

How to use this worksheet

For the adulteration section, discuss one real example you have heard of in the news or at a market. Grade 5 students write far better proposals when the problem is local rather than textbook.

Sample questions from this worksheet

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.
