What this worksheet teaches

• Describe why roughage and water are needed even though they give no energy.
• Compare methods of food preservation - drying, salting, refrigeration, canning - and say when each is used.
• Trace the journey of water from a source to a tap, and identify where it can get contaminated.
• Explain how everyday water wastage happens at home and calculate a simple way to reduce it.

How to use this worksheet

For the preservation section, find one dried, one salted and one refrigerated item at home and line them up. Writing the answers next to three real examples beats reciting the list.

1. Digestion ends in the:
2. Which food gives the MOST energy?

Frequently asked questions

Why is water called a nutrient if it gives no energy?

Because the body cannot carry out digestion, transport nutrients or remove waste without it. Grade 4 syllabuses class both water and roughage as essential even though neither supplies energy.

Which deficiency diseases should my child know?

Typically night blindness (vitamin A), scurvy (vitamin C), rickets (vitamin D), anaemia (iron), goitre (iodine) and beri-beri (vitamin B1) - the set most Grade 4 textbooks use.

Does the worksheet need a science lab or experiment?

No. Everything is answerable on paper, though a two-minute look at kitchen labels and preserved foods makes the answers noticeably stronger.
