Background: Liquid water is a fluid. The hydrogen bonds in liquid water constantly break and reform as the water molecules tumble past one another. As water cools, its molecular motion slows and the molecules move gradually closer to one another. The density of any liquid increases as its temperature decreases. For most liquids, this continues as the liquid freezes and the solid state is denser than the liquid state. However, water behaves differently. It actually reaches its highest density at about 4°C.

Situation: Both was pouring drinks for her kids. She put ice into each cup then poured lemonade into each one. As she carried them outside she notice the ice was floating on top and was careful not to knock it out.

Question: Will thi ice sink or rise as it melts?

Situation: All the recent winter weather had left the river partially frozen. Mark was looking at the huge chunks of ice floating down the river when he realized that they were going to get caught on the bridge little ways down river. sure enough the ice hit the bridge and ended up damaging it. Over the next few days the weather got warmer and the ice melted.
