CBSE Grade 6 Science Exam Survival Guide

Window: Bio + Materials + Physics basics

Must-do topics (what to learn + how to answer)

1. Food & Components of Food
   • Learn: carbohydrates, proteins, fats, vitamins, minerals, roughage, water.
   • How to answer: name → function → 1 food example (e.g., Protein—growth—pulses/eggs).
2. Separation of Substances
   • Methods: handpicking, sieving, winnowing, decantation, filtration, evaporation, condensation.
   • “Choose the method” trick: solid size? density? soluble?
   • Example: sand + water → sedimentation/decantation/filtration.
3. Changes Around Us
   • Reversible vs irreversible (ice↔water vs burning paper).
   • Add why: “because original substance can/cannot be obtained.”
4. Living Things & Habitat
   • Adaptations match environment (camel—hump, eyelashes; fish—gills, streamlined).
   • Answer frame: habitat → 2 adaptations → how they help.
5. Motion & Measurement
   • Standard units (m, cm, km); least count; zero error on instruments.
   • Example: Ruler starts at 0.5 cm → reading 5.3 mark = (5.3 − 0.5) cm = 4.8 cm.
6. Light, Shadows & Reflections
   • Opaque/transparent/translucent; shadow depends on light + object + screen; pinhole camera idea.
7. Magnets
   • Poles; attraction/repulsion test; making & care of magnets.

Top traps (avoid + fix)

• Writing “because it is big/small” without property words (soluble/insoluble, dense/light).
• No units on measurements; ignoring least count/zero error.
• Listing adaptations without “how it helps.”

Study split

• Bio & Food 35% | Materials & Changes 35% | Motion/Light/Magnets 30%

Quick practice (8 prompts)

1. One food for vitamin C + function.
2. Best way to separate salt + water? Why?
3. Reversible or not: melting wax / rusting iron (give reason).
4. Two desert adaptations.
5. Read a ruler with zero error (make an example).
6. Why does a shadow change size?
7. A magnet breaks—what happens to poles?
8. Name 2 safety rules for magnets.

Last-48h checklist

• Draw and label: pinhole camera, bar magnet with field lines, beam balance, filtration setup.
• 20 flashcards: method → when to use; nutrient → function → food.
• 1 mini-mock (30 min) + review wrongs only.

Exam-day mini-plan

• Start with definition-plus-example questions.
• In “method selection,” write property → method → reason.
• End with diagrams (big labels); 10-min label/units check.
