Class 10 Science
A year along NCERT's own chapter spine: balancing an equation and naming the five kinds of reaction, acids and bases on the pH scale and the salts common salt is turned into, the activity series and how each band of it is won from its ore, carbon's covalent habit and the homologous series it builds, the life processes of the human body and the plant, control by nerve and by hormone, reproduction and the rules of heredity, and closing on light, the eye, and the two effects of an electric current.

- Chemical reactions and equationsLesson
Balance a skeletal equation by counting atoms, name the five kinds of reaction the chapter sets out, and say which substance has been oxidised and which reduced.
- Acids, bases and saltsLesson
Predict what an acid gives with a metal, a carbonate and a base, read a solution's nature off the pH scale, and name the salts that common salt is turned into.
Metals, Non-metals and Carbon
- Metals, non-metals and the reactivity seriesLesson
Rank metals by the activity series, work out the ion a metal or non-metal forms from its electron shells, and say how each band of the series is won from its ore and kept from corroding.
- Carbon and its compoundsLesson
Explain why carbon shares electrons rather than trading them, tell a saturated compound from an unsaturated one, work along a homologous series, and name what soap does to oily dirt.
Life Processes and Control
- Life processesLesson
Trace food through the human gut and blood round the double circulation, say where each digestive juice acts, and explain how a plant moves water up and sugar down.
- Control and coordinationLesson
Follow an impulse along a neuron and round a reflex arc, name what each region of the brain looks after, and tell a plant's tropic growth from an animal's hormone response.
Reproduction and Heredity
- How organisms reproduceLesson
Tell the asexual modes apart by the organism that uses each, follow pollen from stigma to seed and an egg from ovary to implantation, and say why variation is worth the cost of two parents.
- HeredityLesson
Work out the ratios of a Mendelian cross, tell a dominant trait from a recessive one, and explain how chromosomes let two traits be inherited independently and how they settle a child's sex.
Light and the Eye
- Reflection and refraction of lightLesson
Apply the New Cartesian Sign Convention to the mirror and lens formulae, work out magnification and the power of a lens, and read a refractive index for what it says about the speed of light.
- The human eye and the colourful worldLesson
Name the parts of the eye and what each does, tell myopia from hypermetropia and pick the lens that corrects each, and explain dispersion, twinkling and the blue of the sky by refraction and scattering.
Electricity and Magnetism
- ElectricityLesson
Use Ohm's law and the series and parallel rules to find a resistance or a current, work out electric power and energy, and say why a heater's element is an alloy and a fuse is a weak link.
- Magnetic effects of electric currentLesson
Read a field-line diagram for direction and strength, pick the right-hand thumb rule or Fleming's left-hand rule for the job, and explain what the earth wire and the fuse are doing in a house circuit.
