ICSE Class 10 Practical Exam Guide: Physics, Chemistry, Biology 2026

Physics Practical Tips

• Key experiments: Ohm's law, resistors in series/parallel, lens focal length, refraction
• Always draw a circuit diagram before starting electricity experiments
• Record readings in a neat table — at least 5 readings
• Graph: use pencil, label axes, mark points clearly, draw best-fit line
• Viva: know the theory behind each experiment

Chemistry Practical Tips

• Key experiments: Salt analysis (identification of acid radical and basic radical)
• Follow systematic procedure: Dry tests → Wet tests → Confirmatory tests
• Record observations accurately — colour changes, gas evolved, precipitate formed
• Know the reagents and their functions
• Viva: prepare equations for all reactions performed

Biology Practical Tips

• Key: Identify specimens (flower parts, leaf types, bones)
• Drawing: Use pencil only, draw large, label neatly with lines (not arrows)
• Sections: Know T.S. and L.S. of dicot and monocot stem, root, leaf
• Physiology experiments: photosynthesis (starch test), transpiration
• Spotting: Practice identifying specimens — 30 seconds per specimen

Common Mistakes

• Not labelling diagrams — each label carries marks
• Messy observation tables — use ruler for lines
• Not writing units with readings (cm, Ω, V, A)
• Rushing through viva — listen to the full question before answering
• Not cleaning apparatus between experiments (contamination)
