Rate of Transpiration - AQA GCSE Biology Calculation Practice Book

Transpiration rate questions combine practical data with calculation skills, and students often struggle to connect the two. This AQA GCSE Biology workbook builds exam 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 Rate of Transpiration (volume of water lost / time)

- 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)

Rate of transpiration calculations require students to use potometer data to calculate how quickly a plant loses water under different conditions. Questions include the effects of light, humidity, temperature, and wind on transpiration rate.

Common student mistakes this workbook addresses: confusing the distance moved by the bubble with the volume of water lost, not converting time units correctly (minutes to hours), and failing to describe rate as "per unit time" in written answers.

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