Why DO ice cubes float?
I keep a handful of them under my kitchen sink and have a book I refer to this great book for tons of ideas that are inexpensive and fun!
Today we filled a clean pop bottle about three-quarters full of water and drew a line at the fill mark. We froze the bottle overnight, upright and measured the difference the next day. My Kindergartner thought this was pretty cool and not only did we take a simple question about why ice floats and turn it into an opportunity to learn, we incorporated math, measurement, estimation, prediction and already had the supplies readily available.
