RBSE Praveshika Science study guide
RBSE Praveshika Science · Work through your exam, one topic at a time.
Praveshika Science is the science paper of the Praveshika examination conducted by the Board of Secondary Education, Rajasthan (RBSE) - a secondary-level board qualification delivered through the Sanskrit-education stream. Candidates normally reach it after completing the preceding stage of that stream. The RBSE Praveshika Science study guide has 13 sections and about 3,936 words.
01Matter and Its Nature
Matter and Its Nature examines the particle model of matter, the three common states, interconversion of states, and how pure substances differ from mixtures. Questions often ask you to choose a separation method or explain a change in terms of particles.
304 words, about 2 min02Motion
Motion tests how position, distance, displacement, speed, velocity and acceleration are described, including motion graphs and uniform circular motion. Numerical questions usually need the three equations of motion for constant acceleration.
309 words, about 2 min03Force and Gravitation
Force and Gravitation covers Newton's laws, inertia, momentum, action-reaction pairs, the universal law of gravitation, and the difference between mass and weight. Numerical work commonly uses F = ma and W = mg.
331 words, about 2 min04Work, Energy and Sound
Work, Energy and Sound links force and displacement with energy transfer, then applies wave ideas to sound. Expect numericals on work, kinetic and potential energy, power, echo timing, and speed of sound.
330 words, about 2 min05Light and Optics
Light and Optics tests reflection by plane and spherical mirrors, refraction through glass and lenses, image formation, and basic ideas of dispersion and the human eye. Mirror and lens formula numericals are common.
321 words, about 2 min06Electricity and Magnetism
Electricity and Magnetism covers electric current, potential difference, Ohm's law, resistance combinations, heating effects, and basic magnetic effects of current. Numerical questions often combine Ohm's law with series or parallel circuits.
322 words, about 2 min07Chemical Reactions
Chemical Reactions tests how to recognise and classify reactions, write balanced equations, and explain oxidation, reduction, corrosion and rancidity. Expect equation balancing and type identification.
283 words, about 1 min08Acids, Bases and Salts
Acids, Bases and Salts examines indicators, the pH scale, neutralisation, and the preparation and uses of common salts. Questions often test pH reasoning and salt identities.
310 words, about 2 min09Metals, Non-metals and Carbon Compounds
Metals, Non-metals and Carbon Compounds covers reactivity, extraction, alloys and corrosion, then the versatile chemistry of carbon: allotropes, hydrocarbons and functional groups. Metals are generally lustrous, malleable, ductile and good conductors; non-metals are often brittle, dull and poor conductors, except graphite.
288 words, about 1 min10Life Processes and Control and Coordination
Life Processes and Control and Coordination covers nutrition, respiration, transport, excretion, and how nervous and endocrine systems coordinate responses. Expect diagram-based reasoning and function comparisons.
292 words, about 1 min11Reproduction, Heredity and Evolution
Reproduction explains how organisms produce offspring, including asexual and sexual modes, flower structure, pollination, fertilisation and human reproductive systems. Asexual reproduction produces genetically similar offspring from one parent: binary fission, budding, fragmentation, regeneration, spore formation and vegetative propagation.
278 words, about 1 min12Heredity and Evolution
Heredity and Evolution tests inheritance of traits, Mendelian ratios, sex determination and the evidence for evolution. Genetic cross problems are common.
277 words, about 1 min13Environment and Natural Resources
Environment and Natural Resources covers ecosystems, food chains, energy flow, biogeochemical cycles, pollution and conservation of water, soil and forests. An ecosystem includes biotic communities and abiotic factors interacting.
