Three minutes into my second SAT prep class of the summer, I had a 16 year old kid borderline unconscious for a good 10 minutes. He said he felt dizzy and put his head down. A minute later he was sprawled out on three chairs. After a minute of that, I got him onto the floor-- there's no way to fall off. (We rent a conference room in a local church, so there were no desks, just conference tables and folding chairs on a carpeted floor.) I got a bottle of water from one of the kids and kept pouring it on his head and asking questions so I knew he was conscious. I had one of the other kids get his mom's cell number from his cell, and got her on the line. She was there a few minutes later, and knew the drill-- apparently this is not unusual for him in the heat. But she said it was unusual for him to be so out of it for so long. When he got to the point where he was able to stand up (with support from 2 other kids) they walked him out to the car. I just called the house; no answer. Then I called the guy who runs the program and let him know. Never, ever dull.
