Q1.
1. My address — Name: ___ House number/building name: ___ Street name: ___ Village/Town/City: ___ District: ___ State/Union Territory: ___ Country: ___ Planet: ___
Answer

Fill the lines from the smallest place to the biggest place, and write Earth on the last line. That last line is the same for every child in the world — and that is exactly why the box is printed here.

How to fill it, step by step:

  1. Write your full name, the way it is written in the school register.
  2. Write your house number, or the name of your building. If your house has no number, write a landmark — “beside the peepal tree”, “opposite the anganwadi”.
  3. Write the name of your street or lane. In a village this may be your mohalla or tola.
  4. Write your village, town or city.
  5. Write your district. Look at the top of a school notice or a ration card if you are not sure.
  6. Write your State or Union Territory.
  7. Write your country — India.
  8. Write your planet — Earth.

Sample answer — yours will be different for the first seven lines, and exactly the same for the last one.

LineSample answerHow big is this?
NameAarav KumarOne person
House number/building name14, Shanti NivasOne house
Street nameGandhi MargA few hundred people
Village/Town/CityRampurA few thousand people
DistrictVaranasiMany villages and towns together
State/Union TerritoryUttar PradeshCrores of people
CountryIndiaMore than 140 crore people
PlanetEarthEvery single person, animal and plant we know of
Why the box ends with ‘Planet’: Each line you write covers more people than the line above it. By the last line you have included everybody — the child in Kerala, the child in Mongolia, the farmer, the astronaut, and also the cow, the neem tree and the rosy starling. Nobody has a different answer for that line. That is the whole idea of this chapter: the first seven lines make us different; the eighth line makes us one family.
Did you know? DIGIPIN does something similar in a shorter way. It gives every small place in India its own special 10-character digital code — a kind of name tag for your home or school. It helps a postman, an ambulance or a delivery person find you faster, even in a big city or a scattered village.
Q2.
2. Use a globe and find out: a. Are all the oceans on Earth connected with each other?
Answer

Yes. All the oceans are joined together. They are really one huge body of salty water that we have divided into parts and given five names — the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Southern Ocean and the Arctic Ocean.

Check it yourself on the globe:

  1. Put your finger on the sea just south of India. That is the Indian Ocean.
  2. Slide your finger westwards, below the southern tip of Africa. Do not lift it. You are now in the Atlantic Ocean.
  3. Keep sliding west and then south, below South America. Still no land in the way. You are now in the Pacific Ocean.
  4. Keep going west across the Pacific until you are back below Australia and into the Indian Ocean again.
  5. You have gone right round the world without lifting your finger off the water even once. That proves the oceans are connected.
Pacific + Atlantic + Indian + Southern + Arctic = one connected ocean
Water covers about three-fourths of the Earth's surface
Why this matters in this chapter: Because the water is joined, a fish, a turtle or a whale can swim from one country's coast to another's without ever crossing a border. Rubbish thrown into a river in one place can also be carried by that same water to a beach far away. Connected water is a gift and a warning at the same time — it is the clearest proof that nature has no boundaries.
Look again: The blue on the globe is not one flat colour. Light blue usually means shallow water near the coast; dark blue means the deep, open ocean. Look for the light blue ring around India — that is where our fishing boats go.
Q3.
2. Use a globe and find out: b. Where is India on the globe?
Answer

India is in the southern part of Asia, north of the Indian Ocean. Turn the globe until you find the big landmass of Asia. India hangs down from it like a wide triangle pointing into the sea.

How to find it in five steps:

  1. Find the equator — the line drawn right around the middle of the globe. India lies above it, in the northern half of the world.
  2. Find the biggest landmass on the globe. That is Asia.
  3. Look at the southern edge of Asia for a wide triangle of land dipping into the sea. That is India.
  4. Look for the mountains marked along its top edge — that is the Himalaya.
  5. Now look at the water around it. The sea on India's west is the Arabian Sea, on its east is the Bay of Bengal, and below the pointed tip is the Indian Ocean.
Direction from IndiaWhat you will see on the globe
NorthThe Himalaya, and beyond them China and Nepal, Bhutan
WestPakistan, the Arabian Sea, and further away the Arab lands
EastBangladesh, Myanmar and the Bay of Bengal
SouthSri Lanka, and then the wide open Indian Ocean
Far north-westRussia and Mongolia — where our winter birds come from
Right across the worldSouth America and Mexico — where chilli and marigold came from
One thing worth noticing: India is the only country in the world with an ocean named after it. That is not an accident. For thousands of years ships sailed across that ocean carrying our spices, cloth and sugar out, and bringing dates, lemons and later chillies in. The position of India on the globe is the reason so many of this chapter's stories pass through it.
Your teacher may show you these too: Mexico, Portugal, South America, Brazil, Russia and Mongolia. Find each one on the globe as you read its story, and put a small paper flag on it. By the end of the chapter your globe will be covered with flags.
