Hypothesis, tests and observations
We tried to roll down an inclined bench
some objects found in the classrom and
then again down a small hill.
ELIA: the cube was slower.
FRANCESCO L.: the squares are slow,
the cirles are faster.
ARIANNA: the cube only rolls on one
side and the bobbin rolls on all sides.
ARIANNA: the cube slips because it has
the points (corner) that stop it.
ELIA: does it have suction cups?
(talking about the mat that doesn't
slide down)…the rough texture sticks to
the ground.
CAMILLA: in my opinion none of this
objects will work on the grass.
