Terrain course: test and refine

Test it · Judge it · Improve it

FORGE Test · Evaluate · Refine

Today's goal

Test the car on the terrain course three times, changing one thing each time, then revise your claim about what controls its behaviour.

By the end

Three terrain-course tests, one change each, and a revised claim with the earlier version kept visible.

What we'll do (60 minutes)

Walk the course as a class and predict where problems will happen.8 min
Test 1: run, record, and note one change and why.14 min
Make the change, predict, Test 2.10 min
Make the change, predict, Test 3.10 min
Update your claim: what controls the car's behaviour? Evidence, a revision if your thinking changed, confidence, limitation.13 min
Pack away.5 min

Need a hand?

Each change chosen from a short list, using a reason frame: "Last time ___ happened, so I will change ___."

Want a challenge?

Propose and justify every change independently, and discuss how a mechanical change and a code change might interact.
