1.1 Physical Quantities and Measurement Techniques [IGCSE Physics (0625)] — Full Lesson (PPT+Q&A)

A complete lesson introducing measurement, precision, and vectors/scalars for Cambridge IGCSE Physics (0625). Students learn how to measure length, volume, and time using rulers, measuring cylinders, and stop-clocks, including methods to reduce human error through repeated readings and averaging. The lesson explains the difference between scalar and vector quantities, with clear examples and diagrams, and shows how to determine the resultant of two perpendicular vectors both graphically and by calculation. Includes visuals, retrieval questions, and short activities linking to experimental contexts such as pendulum timing and paper-thickness measurement. All slides are fully editable and designed for direct classroom use or digital display
