Quick explanation
Carry out Required Practical 7 by planning and performing an investigation into the effect of a factor on human reaction time
- This point belongs to The human nervous system, especially Structure and function.
- You need to be able to carry out Required Practical 7 by planning and performing an investigation into the effect of a factor on human reaction time.
- The key ideas to know are required practical and reaction time.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Structure and function to exam-style questions, flashcards, and revision notes for The human nervous system.
Quick student answer
What are the variables in the carry out Required Practical 7 by planning and performing an investigation into the effect of a factor on human reaction time?
Direct answer
In Biology, this page helps you handle practical questions about carry out Required Practical 7 by planning and performing an investigation into the effect of a factor on human reaction time in The human nervous system. Focus on the independent, dependent and control variables, the method, and how the evidence supports a conclusion. Key terms to check are reaction time and required practical.
Key terms
- reaction time: In Structure and function, reaction time means the duration taken for an organism to respond to a stimulus. This matters in The human nervous system because it supports the learning objective to carry out Required Practical 7 by planning and performing an investigation into the effect of a factor on human reaction time. Use reaction time only in this subtopic-relevant sense so the definition stays concise, curriculum-specific, and useful for AQA GCSE Biology revision. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.
- required practical: A structured investigation designed to explore the effect of a specific factor on human reaction time.
Common trap
Ignoring Control Variables: Ensure to list all control variables and explain how they will be kept constant throughout the experiment.

Structure and function
- Describe the pathway in which receptor cells detect stimuli, sensory neurones carry impulses to the CNS, the CNS coordinates a response and motor neurones carry impulses to effectors.
