An experiment was conducted to determine how the diameter of a wooden dowel would affect the depth that the dowel would penetrate the sand. In a box containing 30kg of sand 80 gram weights were dropped from the height 15cm onto each of the five wooden dowels. The diameters of the wooden dowels were 2cm, 4cm, 6cm, 8cm, and 10cm. The amount of depth into the sand was measured using a ruler after each trial. Independent Variable: Dependent Variable: Control Variables: 1. 2. 3.
