1. The independent variable of this science fair project is the length of the arch. The dependent variable is the amount of weight place on the arch before it breaks. This is determined by measuring the weight of the load using the weighing machine. The constants (control variables) are the distance between the pillar, the type of wood used and the dimension (width and thickness) of the wood. 2. Cut the plywood into smaller pieces, of width 100 mm. Cut 4 pieces of plywood into the following lengths – 500mm, 550mm, 600mm, 650mm, 700mm, 750mm, 800mm and 850mm. Draw ..... |
