Parts and their functions

• Observe and measure (प्रेक्षण और मापन) — Look carefully (the magnifying glass) and measure with standard SI units.
• Ask a question (प्रश्न पूछना) — A clear, testable question gives direction (the compass). Yes/no questions help less.
• Build a model (मॉडल बनाना) — Simplify: keep what matters, deliberately ignore the rest (e.g. treat a car as a point).
• Predict (पूर्वानुमान) — Use laws, theories and maths to say what should happen — a reasoned expectation, not a guess.
• Test (परीक्षण) — Compare the prediction with new observations or an experiment.
• Keep or revise (रखिए या सुधारिए) — If it matches, confidence grows; if not, re-examine assumptions, model or measurements.
• Evidence decides (प्रमाण तय करता है) — Ideas are accepted or rejected only on evidence, never on opinion. No theory is final.
