What you’ll learn7 learning objectivesChoose one objective for a focused lesson, or study the complete topic.P3.1Successful collection of dataSet up apparatus without assistance, follow written instructions and diagrams including circuit diagrams, collect an appropriate quantity of data, repeat readings where appropriate and use common laboratory apparatus correctly.Syllabus objectiveP3.2Quality of dataMake and record accurate measurements, choose a range that spans the largest possible values within the equipment or instructions, and recognise when data quality is judged by scatter, supervisor data or known values.Syllabus objectiveP3.3Tables, recording and significant figuresPresent numerical data in a single table with raw and calculated values, use quantity/unit headings, record precision consistently, show calculation working and justify significant figures in calculated quantities.Syllabus objectiveP3.4Graph layout, plotting and trend linesLabel graph axes with quantity and unit, choose readable scales and false origins where appropriate, plot points accurately, draw best-fit lines or curves, and draw tangents to curves.Syllabus objectiveP3.5Graph interpretation and uncertaintiesRelate straight-line graphs to y = mx + c, determine gradients and intercepts, read coordinates from trend lines, estimate absolute and percentage uncertainties, and use half-range for repeated readings where appropriate.Syllabus objectiveP3.6Conclusions, limitations and improvementsDraw conclusions including constants, judge whether data support a hypothesis, make predictions, identify procedural limitations and significant uncertainty sources, and suggest realistic improvements or extensions.Syllabus objectiveP3.7Apparatus familiarity and safe practiceUse typical Paper 3 apparatus such as meters, calipers, micrometers, thermometers, stopwatches, balances, springs, magnets, circuits, heating equipment and measuring tools with appropriate laboratory safety awareness.Syllabus objective
