The purpose of this lab was to figure out the trajectory of the sun based on datas collected. In order to collect my data, I personally glued a pencil to a paper, and from 10 am to 16 pm on January 26th, I collected the length of the shadow. Attached is an approximation of the trajectory of the sun based on those data*

* During the experiment, I forgot to use a compass, therefore I had to use SunCalc in order to draw the trajectory.

Finally, here is the actual trajectory of the sun during January 26th, 2014.
