**THE STUDY OF THE AMOUNT OF LIGHT BLOCKED BY SUGAR AND SALT**
Lily L. 2012 - 2013

ABSTRACT
The purpose of this study was to determine the amount of light was blocked by sugar and salt before and after they had dissolved. The molecules in the liquid that cause the dissolving are called the solvent and the molecules in the powder that is being dissolved are called the solute. Sugar and salt were placed into a beaker to determine their solubility and the amount of light that they blocked. It was determined that sugar and non-iodized salt block about the same amount of light due to their solubility in water. Sugar and non-iodized salt both have solubility in water, which causes them to dissolve, but iodized salt contains iodine, which cannot dissolve in water.

 An improvement to this experiment would be to use a room with no background light as a work space. This way, the light probe would detect the light produced by the flashlight more precisely. To make the experiments more creative, different powders such as powdered sugar, and borax could be used to determine the amount of light that they block. Different liquids such as juice and colored water could also be used. ======
