To begin, we were told the final results of the experiment before we started in order to know what to look for when conducting the experiment and analyzing our data. We had determined ahead of time that to know if the solutions contained starch, glucose, chloride, protein, or glucose; we needed to see a color change during the mixing of two solutions.

We also concluded that the McMush did have starch because when it was mixed with the solutions, it turned completely black which matched the data from our previously data table. In addition for testing the McMush for starch, chloride, protein, or glucose; we checked the lipid content by putting a little amount of it on a paper towel and letting it dry. Once dry, we help it up to a light and saw little chunks in the paper towel and areas were the paper towel was translucent. This proved there was fat within the McMush.
