Over the past few weeks year 5 have been looking at the different effect of forces, and how we can change this impact. This week, we went outdoors and tested the effect of air resistance, whilst running with different paper. We ran for 25 metres, carrying nothing, a small piece of paper in front of us and finally a larger piece of paper. We found that it was harder (and therefore we were slower) when we had the larger surface area in front of us.
