3.4 Micronutrients — Vitamins and Minerals

In Part 1 we learnt about big nutrients like carbohydrates, proteins and fats. Our body also needs tiny amounts of very special nutrients called vitamins and minerals. Though tiny, they are essential — without them we fall sick, even if we eat lots of rice and dal!

🧠 Why "micro"? We need them in very small quantities — often just a few milligrams a day. But without them, our body cannot function properly.

The Main Vitamins 🌈

VitaminWhat it doesFood SourcesDeficiency Disease
Vitamin A 👁️Keeps eyes & skin healthyPapaya, carrot, mango, milk, green leafy vegetablesNight blindness — trouble seeing in dim light
Vitamin B₁ ⚡Helps body get energy from food; keeps nerves healthyLegumes, nuts, whole grains, seeds, milk productsBeriberi — swelling, tingling, burning in feet
Vitamin C 🍊Helps body fight diseases and heal woundsAmla, guava, green chilli, orange, lemon, tomatoScurvy — bleeding gums, slow wound healing
Vitamin D ☀️Helps bones absorb calcium — for strong bonesSunlight on skin, milk, butter, fish, eggsRickets — soft, bent bones
🌞 Sunshine vitamin: Vitamin D is the ONLY vitamin our body can make on its own — our skin makes it when sunlight falls on it. 15 minutes of morning sun = free vitamin D!

The Main Minerals 🧱

MineralWhat it doesFood SourcesDeficiency Disease
Calcium 🦴Builds strong bones & teethMilk, curd, cheese, paneer, ragiWeak bones, tooth decay
Iodine 🧠Needed for physical and mental activity (thyroid hormone)Seaweed, singhada (water chestnut), iodised saltGoitre — swelling in front of neck
Iron 🩸Important part of blood (haemoglobin) — carries oxygenGreen leafy vegetables, beetroot, pomegranate, jaggeryAnaemia — weakness, shortness of breath
🧂 Use iodised salt: By law, most packed salt in India has iodine added — this simple change has dramatically reduced goitre in the country. Always check "iodised" on the pack!
No Vitamin A(carrots, papaya) Night blindness 👁️ No Vitamin C(amla, orange) Scurvy 🩹 No Vitamin D(sunlight, milk) Rickets 🦴 No Iodine(iodised salt) Goitre 🧣 No Iron (greens) Anaemia 🩸 💡 Remember Missing nutrient = deficiency disease Eat variety!

🔬 Activity — Match the Deficiency L2

Match each person's complaint with the likely missing nutrient:

ComplaintMissing Nutrient?
Riya can't see well in the evening.?
Aman's gums bleed when brushing.?
Noor's neck has a swelling in front.?
Dev feels tired and short of breath.?
🤔 Predict: Write your answers before peeking!
Riya — Vitamin A (night blindness). Aman — Vitamin C (scurvy). Noor — Iodine (goitre). Dev — Iron (anaemia).

3.5 A Balanced Diet ⚖️

If you eat only rice, you get energy but no protein, vitamins or minerals. If you eat only sweets, you get lots of sugar but little of everything else. A balanced diet is one that has all the nutrients in the right proportions.

🍽️ A balanced diet = Carbohydrates + Proteins + Fats + Vitamins + Minerals + Water + Dietary Fibre — all together, every day.

How much of each nutrient we need depends on:

  • Age: A growing Grade 6 child needs more protein than a grandparent.
  • Activity: A kabaddi player needs more energy food than someone who mostly studies.
  • Health: When you are ill, you need more fluids and certain vitamins.
  • Weather: In summer we need more water; in winter, more warm foods.

The Wisdom of Seasonal, Local Foods 🌱

Our grandparents knew what modern science now confirms: foods grown in your own region, in their natural season, are tastiest and most nutritious. They are also cheaper, and travel shorter distances (you'll learn about food miles in Part 3!).

Seasonal Foods ☀️ Summer Mango, Watermelon Lychee, Cucumber 🌧️ Monsoon Corn, Jamun Pears, Okra ❄️ Winter Orange, Guava Spinach, Carrot 🌸 Spring Strawberry, Papaya Peas, Methi
A seasonal food wheel of India — eat with the seasons!

🧠 Competency-Based Questions

Ravi's family members all have different complaints. Ravi's mother has weak bones; his father's neck has a swelling in front; his grandmother's gums bleed; his younger sister Meena has trouble seeing in dim light; Ravi himself feels tired and short of breath after running.

Q1. Which nutrient is likely missing in Ravi's mother's diet? L3

  • A. Vitamin A
  • B. Iodine
  • C. Calcium (and Vitamin D)
  • D. Vitamin C
C — Calcium (often with Vitamin D). Weak bones come from lack of calcium, which builds bones.

Q2. Meena's night-vision problem is caused by deficiency of: L1

  • A. Vitamin A
  • B. Vitamin B₁
  • C. Vitamin C
  • D. Iron
A — Vitamin A. Deficiency causes night blindness. Carrots, papaya and leafy vegetables are rich sources.

Q3. Suggest ONE food item each that will help each family member. L3

Mother — milk/paneer (calcium); Father — iodised salt/water-chestnut (iodine, for goitre); Grandmother — amla/orange (vitamin C); Meena — carrot/papaya (vitamin A); Ravi — spinach/jaggery/pomegranate (iron).

Q4. Fill in: A ______ diet contains all the nutrients in the right proportions. L1

Balanced. A balanced diet has carbs, proteins, fats, vitamins, minerals, water and fibre.

Q5. True/False: Since milk contains proteins, fats, and calcium, a person can live on milk alone. L4

False. Milk lacks enough iron, vitamin C and dietary fibre. No single food is "complete" — variety is essential for balance.

🧩 Assertion – Reason

Assertion (A): Eating iodised salt prevents goitre.

Reason (R): Iodine is needed by the body for proper physical and mental activity.

  • A. Both true, R explains A.
  • B. Both true, R does not explain A.
  • C. A true, R false.
  • D. A false, R true.
A. Iodised salt supplies iodine, whose deficiency causes goitre — so R correctly explains A.

Assertion (A): Grandmother's diet of only rice and pickle is a balanced diet.

Reason (R): Rice contains all seven nutrients.

  • A. Both true, R explains A.
  • B. Both true, R does not explain A.
  • C. A true, R false.
  • D. A false, R true.
A false, R false — none of the four options fit perfectly; best choice is that BOTH are false. (Convention: if both are false, many CBSE papers still mark closest as per choices; the intended pedagogical takeaway — rice is mainly carbs, and rice+pickle is NOT a balanced diet.)

Assertion (A): Playing outside in the morning sunlight for 15 minutes is good for health.

Reason (R): Sunlight helps our skin make vitamin D, which keeps bones strong.

  • A. Both true, R explains A.
  • B. Both true, R does not explain A.
  • C. A true, R false.
  • D. A false, R true.
A. Morning sunlight helps our skin produce vitamin D, which keeps bones strong — Reason explains Assertion.

The key ideas in 'Vitamins, Minerals and a Balanced Diet' for Class 6 Science are: vitamins, minerals, deficiency diseases, balanced diet, scurvy, rickets, anaemia, healthy eating. Students should be able to say each term in their own words, give one or two easy examples from daily life, and draw a small labelled diagram where needed. A good way to revise is to make flashcards, write a short note in the science notebook, and solve the NCERT in-text and exercise questions of Chapter 3. Linking every idea to something seen at home or school — in the kitchen, garden, playground or sky — makes these ideas easy to remember for unit tests and the annual CBSE examination.

How is Vitamins, Minerals and a Balanced Diet taught using activities in NCERT Curiosity Class 6?

NCERT Curiosity Class 6 Science teaches 'Vitamins, Minerals and a Balanced Diet' through an inquiry-based approach using Predict–Observe–Explain activities. Students first make a guess, then try a small experiment with safe, easily available materials, and finally explain what happened and why. This matches the NEP 2020 focus on learning by doing. For Chapter 3 — Mindful Eating: A Path to a Healthy Body — the textbook has hands-on tasks, labelled pictures and thinking questions built for Bloom's Taxonomy Levels 1 to 6. Teachers use these activities, along with competency-based questions (CBQs) and assertion–reason items, to check real understanding instead of only rote learning.

What real-life examples of vitamins can Class 6 students see at home?

Class 6 students can see vitamins at home in many simple ways linked to 'Vitamins, Minerals and a Balanced Diet'. Kitchens, school bags, playgrounds, the garden and the night sky are full of examples that match NCERT Chapter 3 — Mindful Eating: A Path to a Healthy Body. For example, students can look at food labels, watch changes while cooking, try safe activities with water, magnets or shadows, and observe the Sun, Moon and weather each day. Keeping a small science diary — with the date, what was observed and a quick drawing — turns daily life into a mini science lab. These real-life links make concepts easy to remember and help in answering competency-based questions in CBSE Class 6 Science.

How does 'Vitamins, Minerals and a Balanced Diet' connect to other chapters of Class 6 Science?

'Vitamins, Minerals and a Balanced Diet' connects to many other chapters in NCERT Class 6 Science Curiosity. The ideas of vitamins come back when students study related topics like diversity in the living world, food, magnets, measurement, materials, temperature, water, separation, habitats, natural resources and the solar system.
