Practical skills — IGCSE Physics (0625) questions by topic
Practical skills questions ask you to record a thermometer reading to the correct precision, plot and draw a line of best fit for a spring's extension against load, plan an experiment investigating how a beaker's exposed surface area affects cooling rate, and identify what other length must be measured to find a tank's water volume. Calculate, measure, state, suggest and describe are the top command words, so exact reading of scales and careful graph construction matter as much as the underlying physics.
Marks range from 1 to 13 across the 127 real questions gathered here, from 2023 to 2025 papers. Because examiners repeatedly flag small precision errors in these tasks, submit your readings, tables and graphs for instant marking so a reading taken to the wrong number of significant figures is caught before it becomes a habit.
What examiners look for
- A recurring criticism is giving a value that was much too large, likely read from the wrong end of a scale, or not recording lengths and extensions to the nearest millimetre as required.
- Examiners note lines of best fit sometimes not starting both axes at the origin as instructed, or drawn as a series of straight segments joining each plot rather than one smooth line.
- A common mistake was drawing too small a triangle to find a gradient, which gives a less accurate result, or rounding a time for 20 oscillations to only 2 significant figures before entering it in the table.
- Strong answers recorded a realistic starting length, calculated extensions correctly from increasing load values, and drew a clear, large triangle to obtain gradient information.
- Reports praise candidates who labelled axes correctly the right way round, plotted accurately with neat crosses or circled dots, and calculated scale ratios successfully to 2 or 3 significant figures.
