Do heavy things really fall faster than light ones?

Show of hands — before you project anything

Predict before we test: flat paper vs scrunched paper from the same height — which lands first and why?

  • A Way more than you'd guess
  • B About what you'd guess
  • C Way less than you'd guess

Count the votes out loud. Hold them to it — then watch.

Discussion prompts

  • Predict before we test: flat paper vs scrunched paper from the same height — which lands first and why?
  • Gravity pulls harder on the heavy ball, so why doesn't it win the race? Talk it out before the reveal.
  • If we took all the air out of the room, what would change for the feather? Predict, then we watch the tube.

Where it shows up in real life

  • A leaf or feather drifting down slowly while a dropped key falls straight and fast
  • A parachute catching air to float a skydiver down gently
  • Rain falling softly instead of stinging because the air slows the drops
