Units – Lesson, Worksheet & Mark Scheme – Unit 1 – IGCSE Physics
SI Units, Prefixes, Standard Form and Rearranging Equations

This Synapse Science resource launches the Edexcel IGCSE Physics course. It introduces the SI units and symbols students need for Unit 1, the difference between base and derived units, and the prefixes and standard form used in every calculation that follows.

Students also practise converting units, rearranging equations and giving answers to the right number of significant figures.
