Science Scientific Inquiry Meta 9–11 yrs

Controlling variables

控制变量

Description

Plan different types of scientific enquiries to answer questions, recognising and controlling variables where necessary

Mastery Evidence
  • ✓ Independently plan an investigation identifying the independent, dependent, and controlled variables
  • ✓ 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 your child 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?
