Unit Overview
Unit 3: Dreams and Discoveries is about curiosity — the urge to invent, to imagine and to explore. A boy builds "inventions" at home, a child dreams while floating paper boats, and a girl discovers India through a long journey. The unit ends by reminding us that creativity is "thinking new things"; innovation is "doing new things", and it introduces Indian inventors such as Sushruta, Dr. Janaki Ammal, Dr. A.P.J. Abdul Kalam and Dr. Narinder Singh Kapany.
1. My Brother's Great Invention — Anita Rau Badami (story)
Narrator: Anita, fourteen. Main character: her brother Anand, one year younger, who "thinks he is a scientist" and loves "tinkering" with gadgets, dynamos and planks of wood.
Part I — The burglar alarm. After a rush of thefts in the colony, Anand draws a blueprint for a burglar alarm. It rings when the door is opened gently (because a thief opens doors "stealthily") and drops a water bag on the intruder. Papa, who always opens the door softly, gets soaked:
"Who put that water bag here?" roared my father from the front doorstep.
Inspired by the film Back to the Future, Anand next builds a time machine in his room — wires, springs, levers, bulbs and a huge control panel. Papa says "When I say NO, I mean NO." Ma and Papa leave for a wedding in Kharagpur, and Anand promises not to use the machine.
Part II — The night intruder. At about 11:30 p.m. Anita hears scratching and a click at the door. A "ruffianly fellow with a green scarf" enters — Boppa, the man who had recently begun sweeping the compounds. He locks the children in and asks for their father's room. Anand, showing presence of mind, points to his own room (where the time machine is). There is a crash, a scream, a humming sound… The neighbours — Mr. and Mrs. Sharma and Dr. Mohan — rescue the children. Boppa has vanished; only his green scarf lies near the switch panel. Anand insists Boppa travelled into the past. Papa dismantles the machine ("maybe he also had a niggling suspicion that it worked"), and Anand starts a new project — a telephone to contact creatures in outer space!
Message: curiosity and creativity are valuable, but inventions must be safe and responsible. The open ending leaves readers wondering what happened to Boppa.
2. Paper Boats — Rabindranath Tagore (prose poem)
A child floats paper boats "day by day" down a running stream, writing his name and his village's name on them in "big black letters", hoping someone "in some strange land" will know who he is. He loads them with shiuli flowers — "blooms of the dawn". The white clouds look like "bulging sails" sent by a playmate in the sky to race with his boats. At night he dreams:
The fairies of sleep are sailing in them, and the lading is their baskets full of dreams.
Themes: innocence, imagination and playfulness. Tone: gentle and wishful; mood: thoughtful. Symbols: paper boats = the child's hopes and messages to the world; shiuli flowers = purity, beauty, a new day; midnight stars = the vast universe and dreams continuing through the night. Devices: alliteration ("big black"), imagery, repetition ("day by day", "one by one", "on and on").
3. North, South, East, West — C.G. Salamander (postcards)
Shaana, who lives on Rameswaram island, travels across India with Amma and Appa and writes postcards to her class:
Thajiwas glacier, Kashmir — blue-white glaciers, four layers of clothes; her parents say there was more snow last year.Himachal Pradesh — chirping birds at sunrise; "bears growling" turn out to be Appa snoring.Arunachal Pradesh — far from Himachal (east, not north); a thick forest and a treehouse; hopes to see red pandas.Sundarbans, West Bengal — wetlands, mangroves growing in seawater, crocodiles; Amma is sad about the flooding.Gujarat desert — "like a beach without the sea"; colourful clothes; scores 88 per cent in Amma's surprise test.Narmada river — wild rafting; Appa decides never to raft again.Goa — plateaus, hills, beaches and tunnels; Shaana is no longer afraid of tunnels.Chennai to Puducherry — surfing (she fell only twice).Pamban bridge and Olaikaadu beach — then home.Message: India's geography and cultures are wonderfully diverse; less snow and more flooding hint at a changing environment.

Thinking the burglar alarm failed randomly — it was designed to ring when the door opened gently, which is exactly how Papa opens it.Saying Boppa was a stranger — he was the sweeper of their row of houses.Calling Paper Boats a sad poem — its tone is gentle and wishful."Himachal and Arunachal are neighbours" — Shaana learns one is in the north, the other in the east."Neither the passengers nor the taxi driver were…" — the verb agrees with the nearer subject: was.
