Magnification Calculations - AQA GCSE Biology Calculation Practice Book

Struggling with magnification calculations? This AQA GCSE Biology workbook takes students from zero confidence to exam-ready 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 Magnification (M = image size / actual size)

- 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: 4.1 Cell Biology (Combined Science and Triple Biology)

Magnification calculations test whether students can use the formula to find magnification, image size, or actual size from microscopy data. Students work with diagrams of cells, convert between micrometres and millimetres, and apply the formula in both directions.

Common student mistakes this workbook addresses: forgetting to convert units before substituting into the formula, dividing the wrong way round when rearranging, confusing image size with actual size, and not including the multiplication sign (x) when stating magnification.

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