WOW with ROBO
Ages 6–10
Which falls first, the ball or the feather?
Predict what happens in ROBO’s race between a ball and a feather.
Why does it happen?
Gravity acts on both objects. In this experiment, air resistance slows the feather more relative to its weight.
Try it yourself
From a low height, drop a flat sheet of paper and a matching crumpled sheet together. Compare how they fall.
