Today, we worked mainly on how to roughly estimate the height of a tall light post, and we did that by using a shadow. By looking at the shadow and the "triangle" the pole made, and comparing it to a ruler as an equivalent, we could divide the shadow of the pole by the shadow of the 1 meter ruler to get the answer, which was 25 meters, while our group got ≈ 30.82 meters. As the ratio of the shadow of the pole to the pole is 22.5 : X, and the ruler was 0.73 : 1 meter, if you divided 22.5 by 0.73, you would get the approximate length of the pole. However, as we took the measurements five minutes apart, and the sun wasn't in a perfect position to measure the best, we did not get very close to the heigh of the pole, which was actually 25 meters.
