Run 3, comparison and your claim

Collect evidence · Compare · Make sense of it · How sure are we? · Say what we found

VOICE Evidence · Compare · Interpret · Uncertainty · Finding

Today's goal

Compare three runs of evidence and build a claim: linked to data, with a confidence rating, a limitation, and an explanation of the car as a system.

By the end

A claim linked to evidence, a confidence rating, one limitation, and a system explanation.

What we'll do (60 minutes)

  1. Enter Run 2 in Kōkiri Lab and compare it with Run 1 using numbers. Did the prediction match?10 min
  2. Choose a second change with a reason that points back to Run 2, predict its effect, and make the change.8 min
  3. Run 3: three trials, recorded on paper.12 min
  4. Evidence block: build a three-run comparison table, write a claim linked to evidence, give a confidence rating and reason, state one limitation, say whether your thinking changed, and explain the car as a system.27 min
  5. Pack away: the body is about to become the base for the motor.3 min

Need a hand?

A claim frame: "Our evidence shows that ___. In Run ___ we got ___ cm." Confidence chosen from three picture cards.

Want a challenge?

A claim covering distance and reliability that names a trade-off, a two-part limitation, and a second explanation that could also fit the data.
