Temperature and Density

For this demonstration, there were 4 jars- two filled with cold (blue) water and two filled with warm (red) water. We placed 1 cold jar upside down over a warm jar, and the other warm jar upside down over the other cold jar. When the warm was over the cold, the water stayed in place. But when the cold was over the warm, the water mixed. This is because warm water rises and cold water sinks.
