Variables1) Independent- type of coffee filter/ item dropped- reaction time2) Dependent- time - velocity3) Controlled- height coffee filter is droppedRandom errors- students fingers triggering motion senors- sounds-gusts of windObservations:Observations when dropping a heavier papfaster since it has less air resistance than thheavier coffee filter. The heavier the paper faster it falls. Another observation is that thshaped like a ball falls at a faster rate than piece of paper.
