With Flags Unfurled

Last year I decided to become a substitute teacher, mainly to see if I would be a good fit for teaching full time. As it turned out, I really enjoyed the opportunity to teach children and watch them grow and develop. One of my favorite times was during the annual science and technology fair that the students had to create projects for. There were all sorts of ideas represented, from air and space to agriculture and body composition. One of the more memorable projects involved using wind as a source of sustainable energy, and in demonstrating it the student used various flags. To generate wind at various levels, there were a couple small circular fans, but I admired their ingenuity by using the overhead vents as part of the demo. The auditorium has a large HVAC system that seems to run constantly, and the exposed ducting and vents were perfect to attach things to. The display was in between two vents at the back of the venue, so the student took small flags and streamers with wind related facts to pique your interest and arrows that led to their display. With the HVAC system running, the little flags and streamers would wave gently in the vents and catch your attention as you walked by. The display was very informative, and the presentation was probably the best of the ones there. Even without the HVAC system blowing the flags in the vents, the whole thing was well thought and put together. I was glad that I was able to be a part of that.
