Math "Height of A Building"

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.

Building compeleted :) vLog day 3 and 4




Hey guys, so we finished our building, got past the "magnitude 9" earthquake, and successfully, kept it up without much movement. Watch the vid for more info.

Day 1 and 2 --- Earthquake Proof Building Project









Hey guys, so we've started building an earthquake
proof building (project for school again), and
we got the base done -- it took a while, had some problems,
but it was worth it :). Base works really well, and we'll post the blueprints next time.

Earthquake-proof Buildings

These buildings are less solid than a short 3 story apartment building, and can sway and move in an earthquake, whereas a 3 story building would be stiff and fall over when the bottom is shifting.
