Two groups get slightly different distances using the same procedure. Should one erase its result?

2. Try the skill

One car is pushed hard and another is gently released. Is that a fair way to compare the cars? Explain.

Answer guide · AC9S1I05

  1. No. Compare the observations, check the procedure and repeat if useful.
  2. No. The starting push also changed. Release them in the same agreed way.
  3. For example: ‘I predicted the ball would go farther, but the cylinder went farther in this test.’ Keep both statements.
  4. For example, ‘Would a third surface give a different distance?’ Accept a related investigable question.

If help is needed: If different cars are being compared, the car is the thing that changes. Keep the other relevant conditions alike; do not claim the same object must always be used.
