Cambridge IGCSE Physics 0625: Practical — Determining Density | Unit 1 | L10

This practical lesson covers syllabus section 1.4 — describing how to determine the density of a liquid, of a regularly shaped solid and of an irregularly shaped solid which sinks (volume by displacement), including the calculations.

PowerPoint includes:
• Retrieval starter with answer slide
• Direct Instruction (I Do) — method for regular solids (measuring dimensions and mass); method for irregular solids using a displacement (Eureka) can and measuring cylinder; key variables, precautions and sources of error
• Practical — students measure regular and irregular objects and record results
• Check for Understanding — MCQs with separate reveal slides
• Independent Practice (You Do) — analysis questions on the worksheet
• Review and Reflect — exit ticket

Worksheet includes:
• Formula box: density and volume by displacement
• Part A results table for regular objects (dimensions, volume, mass, density, accepted value) and Part B displacement-can results table for irregular objects
• Density reference table for identifying materials
• Parts C and D analysis questions on each method, in Cambridge command words
• Part E (Cambridge addition): method and calculation for the density of a liquid
• Full mark scheme on a separate page, grouped by part (32 marks)
