Melting Icebergs

This week's blog post is a prediction about the outcome of a "confirmation inquiry" lab.  This lab, entitled "Melting Icebergs" is a simulation of ice melting in a completely full glass of water.  The ice obviously represents the icebergs melting due to global warming.  Although I have not yet performed the  inquiry, I can make some predictions about the outcome.  My initial thoughts, in connecting this lab to actual global warming, would be to assume that the water would overflow as the ice melted, thus causing "flooding".  After discussing this with my husband and son, I realized that water expands as it freezes.  Therefore, if the ice melts, it should take up less space as water than as ice.  My prediction is that the level of the water will decrease a small amount.
