This comprehensive guide from Bright Tutorials covers everything you need to know — with clear explanations, exam tips, and key points for board exam preparation.
In This Article
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)
