Density and Temperature Demonstration

During the demonstration we collected hot water and cold water.
Cold water was then colored blue, while the hot water was colored red. 

The concept of this demonstration was to see what water would rise to the top, and what water sunk to the bottom.

Alex placed the jar of hot water on top of the jar of cold water.
Brian then placed the jar of cold water on top of the jar of hot water.

When the jars were directly on top of each other, both separated by a piece of paper, Alex and Brian removed the paper. 


Cold water has a higher density then warm water. In that case, the cold water moved to the bottom, while the hot water remained at the top.

Alex's jar stayed the same because her hot water was already on top. Brian's jar on the other hand mixed together because the cold water was trying to get to the bottom, while the hot water was trying to rise.
