When ice melts it goes back to its original state of water. The question is, how does this new melted ice affect the amount of water that was present, and does it matter where it melts? The fifth graders were given two tubs of water and rocks. In the first tub they had to put the block of ice in the water, whereas in the second tub they had to put the block of ice on the rocks. The water respresnted the sea and the rocks represented the land. Which tub of water will have a higher level afterwards? Fifth grade found out that because the ice is already in the water it does not influence the amount of water already there.
