• 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.
• Name the main nutrients - carbohydrates, proteins, fats, vitamins, minerals, water and roughage - and give one food source for each.

How to use this worksheet

Read the nutrition labels on two packets from your kitchen before starting. Grade 4 nutrient questions become concrete the moment a child sees 'carbohydrates' and 'protein' printed in grams on a real packet.

Frequently asked questions

Is roughage the same as fibre?

Yes. Textbooks at this level use 'roughage', and it means the fibre from vegetables, fruit skins and whole grains that helps the body pass waste.

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.
