Food and Its Components (Class 6)

What this worksheet covers

This is an eighteen-question practice worksheet on food and its components for Class 6, written to the pattern of the SOF National Science Olympiad (NSO). It carries 24 marks and is designed to be attempted in 45 minutes, split across three sections — Scientific Reasoning, Applying What You Know and Achievers Section. Every question is multiple choice with exactly one correct option, and every one comes with a fully worked solution rather than just an answer key — so a child who gets one wrong can see where the reasoning went astray instead of only learning that it did.

Skills your child practises

• Applied problem-solving on food and its components at Class 6 level
• Working accurately against a time limit, as the real paper demands
• Scientific Reasoning questions in the olympiad format
• Applying What You Know questions in the olympiad format
• Achievers Section questions in the olympiad format
• Reading worked solutions to find the step that went wrong

Sample questions from this worksheet

A preview of what's inside Food and Its Components (Class 6) — the PDF has the full set, and every question comes with a worked solution like these.

1. 1. Carbohydrates and fats are together called _______ foods.

   • AEnergy-givingcorrect
   • BBody-building
   • CProtective
   • DRoughage
   Solution: Carbohydrates and fats both release energy when broken down in the body, so they are energy-giving foods. Fats give roughly twice as much energy per gram as carbohydrates.

2. 2. A food sample is crushed and shaken with water. A few drops of copper sulphate solution and caustic soda are added, and the mixture turns violet. What does the sample contain?

   • AStarch
   • BVitamin C
   • CFat
   • DProteincorrect
   Solution: The violet colour in this test shows the presence of protein. Iodine would be used for starch and a paper spot test for fat.

3. 3. Consider the following statements.(i) A balanced diet is the same for a growing child and an elderly person.(ii) Roughage supplies no nutrients but is still essential.(iii) Vitamins are needed in small quantities but their absence causes disease.Which of the statements is/are correct?

   • A(i) and (ii) only
   • B(ii) and (iii) onlycorrect
   • C(i) and (iii) only
   • DAll three
   Solution: Statement (i) is false — a growing child needs proportionally more body-building food than an elderly person, so a balanced diet differs with age, sex and activity. Statement (ii) is true; roughage is not digested but it adds bulk and prevents constipation. Statement (iii) is true. Hence (ii) and (iii).
