Selectively Permeable Smells

ABSTRACT: The idea of our experiment was to see how long it took for different scents to diffuse throughout the air. Also does the brand effect how long it will take? My first hypothesis was that it would take a minute at least till we could smell the scent. My second hypothesis was that it wouldn’t affect the time it took to smell it if the brand was different.

PROCEDURE: Our first step was to create a graph so that we could write down data. We also marked out an area of ten feet with duct tape. After that we took out our timers/iPod/iPad and set out four body sprays of our teacher’s choice. Our teacher stood on one side of the tape and we stood on the other. Right when she sprayed we started our timers. She sprayed twice with the first spray. Right when we could smell it we stopped out timers. We took our result and marked it down on the graph we made in the beginning. One of our sprays didn't work. We continued the same procedure the three that were left.

DATA:

BRAND OF BODY SPRAY            2 SQUIRTS OF BODY SPRAY          TIME TOOK TO SMELL

 

Green Apple                                               Yes                                                    18 seconds

Vanilla, Vanilla                                          Yes                                                    15 seconds

Honey-Do Melon                                       Yes                                                     8 seconds

 

CONCLUSION:  My hypothesis was that it would take at least a minute for the scents to diffuse through the air. I was proven wrong as you can see in my data. Also that the brand wouldn’t affect how long it would take to smell I was proven correct. The brand didn’t matter because you could make the same perfume and just put a different brand on it. It was because of how strong it smelled and how it was made not the brand.
