  • Choose the appropriate type of enquiry for the question (fair test, observation over time, pattern seeking, research)
  • Explain why controlling variables is essential for valid results

Assessment prompt

Can Controlling variables plan their own experiment from scratch — deciding what to test, what to measure, what to keep the same, and how many times to repeat it?
