Solar Trajectory Lab

By measuring the shadows of my roommate at different times of the day, more specifically morning, afternoon, and evening, I was able to catch a glimpse of the solar trajectory path. I measured the height of my roommate (68 inches), the different lengths of her shadow in inches, the ordinance of each of those shadows, and took the tangent of her height over the length of her shadow to calculate the sun's position.

Height:            Length:        Angle:                                          Direction:
27 inches         32 in                27/32=.844= 40 degrees          North 175
27 in                49 in                27/49=.551= 29 degrees          NE 147
27 in                134 in              27/143=.202= 11 degrees        NE 96
27 in                100 in              27/100=.270= 15 degrees        NW 122
27 in                56 in                27/56=.482= 26 degrees          NW 139
27 in                35 in                27/35=.771= 38 degrees          NW 161
