What are GCSE required practicals?

They are hands-on investigations your specification expects you to understand in principle: method, variables, equipment, how to present results, and typical examiner pitfalls. Written exams often use them as 6-mark context.

Do AQA, Edexcel and OCR use the same wording?

Core ideas overlap, but command words and exact apparatus lists can differ. Use these guides for the science, then follow your GCSE Biology specification and your teacher’s practical notes.

How should I revise a practical the night before an exam?

Memorise variables (independent, dependent, controls), one fair improvement, and two common mistakes. Then practise explaining the graph or trend without inventing data.

Where can I practise exam questions?

Use StudyVector’s exam question bank and topic practice for GCSE Biology.

GCSE Biology: required practicals

Required practicals are the experiments exam boards expect you to know in principle—even though your school may run slightly different versions. Each guide below includes aim, method, variables, equipment, results, graphs, common mistakes (high yield), exam questions and tips, plus links into your full topic revision on StudyVector.

Why this hub exists

Teachers can point students at one consistent structure: variables and controls first, then method, then mistakes.
Students get scannable steps and “exam traps” without wading through generic lab notes.
Search: every page has a clear H1, meta description, and FAQ schema where it helps.

Bioenergetics

Required practical
Photosynthesis rate (pondweed)
Classic pondweed setup: vary light intensity, keep CO₂ and temperature stable, and measure oxygen or bubbles as a rate.

Cell transport

Required practical
Osmosis in potatoes
Potato cylinders in a range of sugar concentrations: measure mass change and find the isotonic point.
Open guide

Enzymes

Required practical
Enzyme activity (catalase / amylase)
Catalase and peroxide, or amylase and starch: measure initial rate vs temperature or pH with fair controls.
