As far as I know neither of my kids schools have talked to them about it. We did talk about it together as a family, as we have other big and tragic news events. We've talked about what happened, why it might have happened, and then do our best to talk about the positives of the situation - so many people helped! Look at all the folks rushing in to help people, and all the paramedics and abulances and some of the best hospitals in the whole world are right there, etc, etc. I know DS9 still worries and is anxious about stuff like that, but I feel it's better for us to talk with him up front before he hears about things at school (especially from other kids!)
