Iceberg Ahead: How Does Temperature Affect the Density of Water?

Demonstrate how ice floats on water and get the class thinking about why icebergs are so deceiving. Investigators then experiment with mixing water of the same temperature and water of different temperatures. Make sure to explain the concept of density, what happens to water when it freezes, and why density changes as temperature changes and molecular movement slows down. These considerations are imperative to understating what happens during the demonstration and lab activity.
