1. The independent variable for this science fair project is the type of bridge used – open sides, 50% side coverage and 100% side coverage. The dependent variable is the tilt of the angle of the bridge deck caused by the force of wind from the fan. This tilt angle is measured using a protractor placed on the bridge. The constants or control variables are: the speed of the wind from the fan, the length of the bridge, the width of the bridge and the weight of the bridge. 2. Figure 1 above is an illustration of the model .....
