Key Stage 4 - Assessment Ph2 - Sand Piles i) Investigation into Relationship between Volume and Diameter If sand is allowed to fall steadily onto a horizontal, level, and flat surface, it forms conical piles. Our AIM, in this experiment, is to find the effects, on the diameter, caused by varying the volume these conical piles of building sand, and hence, find their relationship with one another, in terms of a graph showing all possible, plausible volumes, applicable in the laboratory, with their respective outcomes. There are two predictions to discuss, the first being the qualitative prediction, explaining itself in simple, common sense terms, followed by a quantitative prediction. Qualitative Prediction: As the volume of the pile increases, I would expect the diameter to increase; this I observed, when I was travelling to school, and saw piles of building sand, cement, grit, and other building materials on the...
