Learning goalsSay it simply

A good investigation follows clear steps, manages risks and makes a fair comparison. Students change one factor, keep other important conditions similar and record what happens.

Learning sequence: Question → Plan → Safety check → Fair test → Record

Success looks like

  • Suggest procedures
  • Identify risks
  • Follow safety rules
  • Plan fair comparisons
  • Record steps

Key idea: A good investigation follows clear steps, manages risks and makes a fair comparison. Students change one factor, keep other important conditions similar and record what happens.

Remember

  • Suggest procedures
  • Identify risks
  • Follow safety rules
  • Plan fair comparisons
  • Record steps

Quick questions

  • What comes before testing?
  • What makes a comparison fair?
  • Name one safety step.
  • Why record the procedure?

If an answer is uncertain, return to the model and explain what each part represents before calculating or drawing a conclusion.

Practice and reviewReady for practice
  • Starting before planning — Agree on steps and safety first.
  • Changing several factors — Change one factor for a clearer comparison.
  • Ignoring clean-up — Safe procedures include clean-up and hand washing where needed.

Read the topic guide and use the teacher slide for instruction. Students can then use the worksheet for written work, open Practice for supported feedback, or take the Test when they are ready.
