The purpose of this lab is to determine the trajectory of the sun based on the height of a pole (in this case we used a pencil), the length of its shadow, and the direction the shadow is cast. A pencil was set up on campus and the height was measured. The length of the shadow and its direction were then measured at the times listed in the table above over a 24 hr period. All this data was used to draw the shadow trajectory image above. SunCalc was used as another visual aid to better understand the trajectory of the sun.
