I love giving my kiddos a question that there is a scientific answer to; but asking them to come up with another reason to explain the phenomena. I tell them it can be silly, or funny, or serious--but it has to be something different from the real reason. Since we have finally begun to feel Fall weather (it's actually in the low '90's here in Texas). It seemed appropriate to discuss why the leaves change color in Fall. We are still working on getting those creative cogs going--I've said it before and I'll say it again: creativity like anything else, takes practice. But some of them did come up with something new. My favorite one is "because they want to be cute".
