Fall is a changeable time. Last week it rained, but it's been hot this week. The max/min thermometer on the science building porch recorded a high of 105 degrees in the shade over the weekend! We've been running our fans at school and at home trying to beat the heat, so here's a practical stumper about fans. What's the best way to place a fan by an open window for maximum cooling effect? Should the fan blow into the room from the outside, or should it blow out the window towards the outside? Why?
