NCERT Solutions · Science · Curiosity
Twelve chapters. One habit: ask why.
The Curiosity textbook trades definitions for experiments. Every chapter below opens onto worked NCERT answers, labelled diagrams and competency-based questions — the kind that ask you to predict what happens, not recite what it’s called.
The Ever-Evolving World of Science
How the scientific method actually works — observe, guess, test, revise — and how yesterday’s discoveries keep rewriting tomorrow.
Read solutions →Exploring Substances: Acidic, Basic and Neutral
Turmeric, litmus and china rose as detectives. Test what’s in your kitchen, then watch an acid and a base cancel each other out.
Read solutions →Electricity: Circuits and their Components
Draw a circuit the way an engineer does. Series or parallel, what a switch really breaks, and why a wire warms up when current runs through it.
Read solutions →The World of Metals and Non-metals
Why copper carries current and sulphur can’t. Lustre, malleability, conductivity — and how those properties decide what a thing gets made of.
Read solutions →Changes Around Us: Physical and Chemical
Ice melts and can freeze back; iron rusts and never returns. Learn the test that tells a reversible change from a permanent one.
Read solutions →Adolescence: A Stage of Growth and Change
The biology behind the growth spurt. What hormones do, why moods shift, and what a healthy body actually needs during these years.
Read solutions →Heat Transfer in Nature
Conduction, convection, radiation — the three routes heat takes. Then use them to explain why the sea breeze arrives every afternoon.
Read solutions →Measurement of Time and Motion
Speed, uniform motion and distance–time graphs — plus the long walk from a sundial’s shadow to an atomic clock that loses a second in a million years.
Read solutions →Twin chapters · life processes
Life Processes in Animals
How an animal body feeds itself, breathes and moves material around — digestion, respiration and circulation, followed end to end.
Read solutions →Life Processes in Plants
The same jobs, solved differently: photosynthesis, transpiration, and the xylem–phloem pipework that lifts water up a tall tree.
Read solutions →Light: Shadows and Reflections
Light travels straight — and everything follows from that. Sharp shadows, the law of reflection, and why your mirror image swaps left for right.
Read solutions →Earth, Moon and the Sun
Rotation makes the day, revolution makes the year. Track the Moon’s phases and work out exactly what has to line up for an eclipse.
Read solutions →Questions students ask us
Short answers on the new syllabus and how to use these solutions.
How is Curiosity different from the old Science textbook?
It’s built around learning by doing. There are more hands-on activities, and concepts are tied to things you can actually see happening — rather than terms you memorise and forget.
What is a competency-based question?
One that tests whether you can use what you know. Instead of “define an acid,” it asks what will happen if lemon juice spills on a marble floor — and expects you to reason it out.
Do the solutions include diagrams?
Yes. Every key diagram — circuits, life processes, ray paths — comes redrawn and clearly labelled, so you can see the structure and the flow before you copy it into your answer sheet.
Why is Adolescence part of a Science course?
It sits under the Living World theme. The chapter looks at growth through a biological lens, so the physical changes of these years are understood as normal, explainable and healthy.
Are these solutions current for 2025–26?
Yes — they follow the latest NCERT Curiosity textbook and NEP 2020 guidelines for this academic cycle.
