Density Calculations - AQA GCSE Physics Practice Book

Density calculations are tested in both the written exam and the required practical, making them one of the most important Physics skills to master. This AQA GCSE Physics workbook builds confidence with 12 scaffolded questions using the EVERY method framework.

The EVERY method breaks each calculation into clear steps: Equation, Values, Enter values into the equation, Rearrange if needed, Your units. Every question has a structured EVERY table for students to complete, building a consistent problem-solving habit. Questions get progressively harder: Q1-3 are straightforward, Q4-6 introduce unit conversions, and Q7-12 require rearranging the formula.

What’s inside:

• 12 progressive questions on Density (density = mass / volume)
• Structured EVERY method table on every question page
• Progressive difficulty: simple substitution, then unit conversions, then rearranging
• Self-assessment tracker with “What made me stuck?” reflection checklist
• Full worked answers for all 12 questions using the EVERY method steps

AQA specification reference: 6.3 Particle Model of Matter (Combined Science and Triple Physics)

Density calculations require students to divide mass by volume for regular and irregular objects. They need to calculate volume from dimensions, convert between g/cm3 and kg/m3, and link density to the required practical using displacement.

Common student mistakes this workbook addresses: confusing mass with weight, dividing volume by mass instead of mass by volume, not converting between kg/m3 and g/cm3 (multiply/divide by 1000), and calculating volume incorrectly for rectangular blocks (length x width x height, not length x width).

Suitable for AQA GCSE Combined Science and Physics (Triple). Works for both foundation and higher tier students.
