👁️ Eyes and Eye Care (Page 206–207)

Think and Discuss: What would you do if you see a blind person waiting to cross the road?
Answer: I would gently ask the person if they need help, and if they say yes, I would hold their hand or guide their arm carefully and help them cross the road safely, watching the traffic on both sides.

👃 Nose and Smell (Page 208–209)

Do you like the smell of Jasmine flower? Why?
Answer: Yes, I like the smell of Jasmine flower because it has a sweet, fresh and pleasant fragrance that makes me feel happy and calm.

👂 Ears and Hearing (Page 210–211)

When there is a very loud noise, you close your ears. Why?
Answer: We close our ears when there is a very loud noise because the sensitive eardrums inside our ears can get damaged by loud sounds. Closing our ears protects them and reduces the discomfort caused by the noise.

Activity: Read the sentences, put (✓) for actions which are safe and put (✗) for unsafe actions.

1. Inserting a stick to clean ears.   ( ✗ )
2. Keep away from loud sounds.   ( ✓ )
3. Use earphones for long hours.   ( ✗ )
4. Go to a doctor if you have an earache.   ( ✓ )

👅 Tongue and Taste (Page 212–213)

How do you feel when you eat any food item?
Answer: When I eat any food item, my tongue senses its taste — whether it is sweet, sour, bitter or salty — and I feel happy when I eat something tasty.

Can you speak without moving your tongue? Just try.
Answer: No, it is very difficult to speak clearly without moving the tongue. This shows that the tongue helps us not only to taste food but also to speak properly.

Activity: Identify whether each habit given below is good or bad and write it down.

1. Brushing teeth and cleaning the tongue daily.   ( Good )
2. Eating food that is too hot.   ( Bad )

🌟 Differently Abled Persons (Page 216–217)

Have you ever seen such types of persons in your surroundings?
Answer: Yes, I have seen differently abled persons in my surroundings, such as a person using a wheelchair or a person who cannot see and uses a stick to walk. We should always be kind, respectful and helpful towards them.

🤝 Good Touch – Bad Touch (Page 218–222)

Which is uncomfortable to you? What can you do when someone touches you?
Answer: A touch that makes me feel scared, embarrassed or unsafe is uncomfortable to me (bad touch). If someone touches me like that, I will say NO firmly, move away quickly, scream for help if needed, and tell a trusted elder about it.

What would you do if a stranger asks you to come with him?
Answer: I would say NO clearly, refuse to go with the stranger, move away quickly to a safe place, and immediately tell my parents or a trusted adult about what happened.

Activity (Page 220): Fill in the blanks.

If a touch makes me feel unsafe, I will say "NO! I don't like this. Stop it!"

I will tell my parents / teacher / a trusted elder.

Activity (Page 222): Identify good and bad touch from the given picture.

⚠ Please verify with the physical book: All five pictures described show known, trusted family members (grandfather, father, a friend, and mother), so all are examples of good touch.

4. Two friends shaking hands — Good touch
5. Mother holding her child — Good touch
