 * THE STUDY OF RECOGNIZING SMELLS WITH AND WITHOUT VICKS**

The purpose of this experiment was to see how well the nose can smell with and without different substances. . When Vicks wasn’t smelled, an average of 78% of smells was recognized and without Vicks an average of 28% of smells was identified correctly. Without vinegar, 100% smells were correct and with vinegar, 0% was correct. With 0mL vinegar, the smells correct were 100%. When 25mL was put in the water, 60% of the smells were correct. With 50mL of vinegar, another 60% of the smells were correct. When 75mL was put in the water solution, 50% of the smells were smelled correctly and when 100mL was put, 0% was correctly identified. Without touching, tasting, hearing, and seeing, the volunteer got 90% of the smells correct. With touching, tasting, hearing, and seeing, the volunteer got 67% correct.
 * ABSTRACT**

In conclusion, different things like certain drinks and medicinal items can usually greatly affect the human sense of smell. This is somewhat important because some things that you drink can sometimes drastically affect the sense of smell. Also, smell molecules have trouble sending messages to the brain when the other senses are being used. So it would be more helpful to use one of the senses at a time rather than all of them at once. What was predicted was correct. Vicks and other substances reduced the human’s sense of smell. Another follow up experiment that could be done is seeing if smell affects taste like switching the two.
