Cardiac Output Calculations - AQA GCSE Biology Calculation Practice Book

Cardiac output is a straightforward equation but students still lose marks by confusing stroke volume with heart rate. This AQA GCSE Biology workbook builds real 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 Cardiac Output (cardiac output = stroke volume x heart rate)

- 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: 4.2 Organisation (Combined Science and Triple Biology)

Cardiac output questions test whether students can calculate the volume of blood pumped by the heart per minute. Students work with data from rest and exercise scenarios, rearrange the formula for any unknown, and convert between different units of volume.

Common student mistakes this workbook addresses: confusing stroke volume (per beat) with cardiac output (per minute), not rearranging the formula correctly when solving for heart rate, giving answers without units, and not converting cm3 to dm3 when required.

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