There are many things I adore about teaching GT children. One of them is they often stump me with their questions. We were talking about getting a class pet for the room and we're going to go with a fish. They were discussing names when one of my quieter students raised their hands and asked "do fish drink water?". My response: "what an excellent question! I'm going to have to look up the answer to that".
That's not the first time I've ever been stumped by these little ones. They've asked why flamingos are pink, how they make bulletproof glass (I think it was after an action-movie weekend)-because you have to be able to still see through it, but it has to be strong too. They are something else.
What I do every year is post a Wonder Wall. Which is just a posterboard with sticky notes available for them to record their questions. On Fridays we take some time and sit down in front of Brainpop or Discovery Education and find the answers. I think encouraging this kind of questioning is so important with any students, but particularly with GT kiddos. It's how everyone learns new things, to think of the question and ask!
