Science forces 20.6.13

In Science we are looking at forces.  We designed an investigation to find out what effect air resistance has on falling objects.  We measured the time it took 5 differently shaped A4 pieces of paper to reach the ground: Flat, halved, quartered, screwed into a ball and an aeroplane.  We found that the larger the surface area of an object the bigger the effect of air resistance in slowing the fall.
