Wrap up of States of Matter

So... I had the fixins for Shamrock Shakes still from St. Patty's day. We didn't make them because somehow one of the wee leprechaun's 4-Color Click-Pen came up missing. I said we wouldn't have the shakes til the pen was found, and it wasn't "found" until like 4 minutes left in the day. By found, I mean that the trickster that took it finally figured out a way to get it out of his possession. Anyway, I had these ingredients and I needed a way to justify it since we are not allowed to use any food at all as a reward (AND I think we have seen behavior in the toilet because they think a few Fruit Loops are going to make a kid fat). So, we are finishing up our states of matter unit and it occurs to me that a float is all of the states of matter, and it even shows a transition from a solid to a liquid. <> We had the floats and the kids told me the states of matter and how we knew each was that type... then we had the floats. AWESOME!!!
