Purpose: 


The purpose of this science fair project is to explore the scientific "Law of Entropy".  The Law of Entropy is defined as a measure of the disorder or randomness in a closed system.  In other words, a classroom that contains books, papers, and pencils scattered all over the place is considered to have a high amount of Entropy.  In contrast, a room that has the books, papers, and pencils neatly stacked together is considered to have a low amount of Entropy.


An item or chemical substance is in a low Entropy state when its components are in a specific "lined" order.  An item or chemical substance is in a high entropy state when its components are in a random order.  High entropy states release heat, while low entropy states absorb heat.


Hypothesis:  


The temperature of a chemical substance, such as a rubber band, is dependent upon the Entropy state of the chemical substance.




Variables:


Temperature of the rubber band (A hot rubber band versus a cold rubber band)

A non-stretched or stretched rubber band


Materials Needed:


  • Medium to large size rubber bands
  • Rubber bands of all different sizes, lengths, widths, and thickness
  • Paper, pencil
