In my gym class (HS level), there is a water fountain in the gym, but we generally don't use it. The only time we use it is during the pacer test (the worst, most strenuous fitness test known to man, lol) or at the end of class. We are allowed to if we ask, but we generally don't. We are all pretty much sweating by the end of gym. The other day, we were playing a really stupid, pointless game, but this one kid, who is fairly athletic, was sweating so bad. His shirt was soaked and sweat was dripping down his face. Not once did he get a drink during class. Of course, when we came downstairs to the locker rooms, most people got one. In elementary gym classes, I really don't think it's necessary to get a drink. JMHO.
