Discussion prompts
- Predict first: same push, one walker with a pole and one without — which one tips slowly enough to catch? Then run it and check.
- Guess what happens to the catching time if we make the pole longer, then test it and explain the change.
- Why does spreading weight far from the middle matter more than just adding heavy weight near the body?
Where it shows up in real life
- Spreading your arms out on a curb or balance beam to stay steady
- A spinning office chair: tuck your arms and you whip around, stick your legs out and you slow down
- A squirrel or cat using a long tail to balance while it walks a narrow edge
