NCERT Class 10 Science
Class 10 Science: Science chapter-wise practice
Physics, chemistry and biology questions are split by topic, with numericals, diagrams and reasoning questions in the mix. Worked solutions show each step and the unit, because that is where most children lose marks.

Chapter 1 Chemical Reactions and Equations
Learn how chemical changes are recognised, written as balanced equations and grouped into important reaction types. Connect redox, corrosion and rancidity with everyday observations and board-style equations.
Topics: Recognising chemical reactions, Writing and balancing equations, Combination and exothermic reactions, Decomposition and endothermic reactions, Displacement and double displacement, Oxidation, reduction and redox, Corrosion and rancidity
-
Chapter 2 Acids, Bases and Salts
Use indicators, reactions, ions and p H to understand acids, bases and salts found in laboratories, kitchens, soil, medicines and building materials.
Topics: Indicators and acid-base nature, Reactions of acids and bases, Ions in water and dilution, p H scale and strength, p H in everyday life, Families and p H of salts, Common salt and sodium compounds, Water of crystallisation and Plaster of Paris
-
Chapter 3 Metals and Non-metals
Compare metals and non-metals by physical and chemical properties, then use reactivity to explain ionic compounds, extraction, corrosion and alloys.
Topics: Physical properties and exceptions, Metal and non-metal oxides, Metals with water and acids, Displacement and activity series, Ionic bond formation, Properties of ionic compounds, Extraction and refining of metals, Corrosion, prevention and alloys
-
Chapter 4 Carbon and its Compounds
Explore why carbon forms millions of compounds through covalent bonding, catenation and functional groups, then apply these ideas to fuels, ethanol, ethanoic acid, soaps and detergents.
Topics: Covalent bonding in carbon, Allotropes of carbon, Tetravalency and catenation, Saturated, unsaturated and isomeric hydrocarbons, Functional groups, homologous series and names, Combustion and other carbon reactions, Ethanol and ethanoic acid, Soaps, detergents and micelles
-
Chapter 5 Life Processes
Understand how living organisms maintain life through nutrition, respiration, transport and excretion, from single cells to humans and plants.
Topics: Life processes and molecular maintenance, Autotrophic nutrition and photosynthesis, Heterotrophic nutrition and human digestion, Cellular respiration pathways, Gas exchange and human respiration, Transport in human beings, Transport in plants, Excretion in humans and plants
-
Chapter 6 Control and Coordination
Trace how animals and plants detect changes and coordinate responses through nerves, muscles and hormones. Practise board-style reasoning on reflexes, brain functions, plant tropisms and endocrine feedback.
Topics: Stimuli, responses and coordination, Neurons and synapses, Reflex arcs and spinal cord, Human brain and protection, Muscles as effectors, Plant movements and tropisms, Plant hormones, Animal hormones and feedback
-
Chapter 7 How do Organisms Reproduce?
Understand why reproduction copies body plans with variation, how organisms use asexual and sexual modes, and how flowering plants and human beings reproduce responsibly.
Topics: DNA copying and variation, Asexual reproduction modes, Vegetative propagation and tissue culture, Sexual reproduction and gametes, Flowering plant reproduction, Puberty and sexual maturation, Human reproductive systems and pregnancy, Reproductive health and contraception
-
Chapter 8 Heredity
Learn how variations accumulate, how Mendel used pea plants to reveal inheritance rules, and why a child's sex in humans depends on the father's X or Y chromosome.
Topics: Variation and selection, Inherited traits and parental contribution, Dominant and recessive traits, Independent inheritance, Genes, proteins and chromosomes, Sex determination in humans
-
Chapter 9 Light: Reflection and Refraction
Master reflection by spherical mirrors, refraction through media and lenses, sign convention, mirror/lens formulae, magnification and lens power with board-style numericals.
Topics: Reflection and mirror terms, Concave mirror images and uses, Convex mirror images and uses, Mirror formula and magnification, Refraction and refractive index, Spherical lenses and image formation, Lens formula, magnification and power, Board applications and ray reasoning
-
Chapter 10 The Human Eye and the Colourful World
Study how the eye focuses light, how lenses correct vision defects, and how prisms and the atmosphere create colours, twinkling and the blue sky.
Topics: Human eye and accommodation, Defects of vision and lenses, Eye donation and cataract, Refraction through a prism, Dispersion and rainbow, Atmospheric refraction, Scattering and colour of sky
-
Chapter 11 Electricity
Learn how charge flows in circuits, how voltage, current and resistance are related, and how electrical energy becomes heat, power and useful work.
Topics: Electric current and closed circuits, Potential difference and circuit diagrams, Ohm's law and resistance, Factors affecting resistance and resistivity, Resistors in series, Resistors in parallel, Heating effect, fuse and electric power
-
Chapter 12 Magnetic Effects of Electric Current
Explore how current produces magnetic fields, how magnetic fields exert forces on current-carrying conductors, and how domestic wiring uses fuses and earthing for safety.
Topics: Magnetic field and field lines, Field due to a straight current-carrying conductor, Circular loop, solenoid and electromagnet, Force on a current-carrying conductor, Domestic electric circuits, Fuse, overloading and electrical safety
-
Chapter 13 Our Environment
See how living things depend on air, water, soil and one another. Learn food chains, ozone damage and waste choices.
Topics: Ecosystem components, Producers, consumers and decomposers, Food chains, trophic levels and energy flow, Food webs and biological magnification, Ozone layer and its depletion, Biodegradable and non-biodegradable waste
Where does the study time go?
In Classes 9 and 10 many children leave home early and come back late after school and coaching. Self-study gets pushed into the last hour of the night, when they are too tired to think clearly. What helps most is knowing exactly which topics deserve that hour.
Tuition is fine, and plenty of children need it. But a tutor with eight or ten children in one batch cannot sit with each of them, and cannot always keep track of what the school did that week. Sometimes the tuition follows its own order of chapters, the child ends up juggling two plans for the same subject, and the confusion shows up in the next test.
NoTuition.in gives that small window some shape: the chapter your child is doing in school, a short activity, practice that explains every mistake, and a clear view for you of what needs work.
Practise Class 10 Science the way the book teaches it
The free plan opens one full chapter in every subject, so you can see how your child gets on before you pay anything.
