What this worksheet teaches

• 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.

• Explain what a deficiency disease is and match common ones to the missing nutrient.

How to use this worksheet

Deficiency diseases are pure memorisation unless linked to a symptom, so say them as pairs out loud - no vitamin A, poor night vision; no vitamin C, bleeding gums; no iron, tiredness. Then let your child fill the table from memory.

Sample questions from this worksheet

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.
