Extreme Weather
Professor Perry Samson organized a large-scaled series of experiments at the University of Michigan Football Stadium a.k.a The Big House today. This event was not only participated and jointly supervised by students from his Extreme Weather (GEOSCI 122) class, but also members of the public.
His students were given the incentive of extra credits to arrive at the stadium early to prepare various types of equipment that would be used for the experiments. Such materials included balloons, ribbons, digital thermometers and soap solution.
An estimated 400-strong crowd of volunteers showed up at the football stadium sporting yellow “Extreme Weather” T-shirts which were given away at the entrance. Men, women and children of various ages were present.
The first of the experiments kicked off promptly at 12pm, which was an experiment involving the measurement of temperature at different levels of the stadium. Soon after was the bubble blowing experiment which was used to determine the direction of the wind and where it would take a near-weightless object throughout the stadium. The experiment was once at each end of the stadium and once under the press-box. Seeing hundreds of bubbles floating in the air at one time was quite a sight to behold.
Then the other experiment which measured the diffusion in the stadium was carried out. At the blow of a whistle, participants one at a time released a balloon and followed it wherever it went. 10 seconds later, another whistle was blown and the participant had to place a marker wherever the balloon was last at.
At the end of the series of experiments, which was around 1.15pm, Professor Samson thanked all the participants signaling the conclusion of this interesting on-campus event.
