Diffusion experiment

Abstract

The purposes of this experiment is to see  if the brands of body spray affects how long it will take to smell it from ten feet away. I don’t think it will be different.

 

Procedure

We measured ten feet. We wrote all the data on a chart. The people who had devices used them for a timer. The teacher then stood ten feet away. We had 4 different body sprays. One didn’t work. She sprayed each one twice. We stopped the timer when we smelled them really strong. We had body rush honeydew, dkny be delicious, jlo didn’t work and bath and body nsp . We recorded the results and here they are.

Data

2 squirts

Brand     yes or no    time

           Body rush                            yes                                   15.25

                 Dkny                                    yes                                   15.90

                 Jlo                                  did not work                      00.00

                 Nsp                                       yes                                   10.61

 

Conclusion

The experiment was to see if different types of body spray affect the time it takes to smell it. 2 sprays took the same time the 3^rd spray was 5 seconds faster to smell. So it does not really matter about the brand. I think I was right about it would not really be different. We did not take into account fans, how much comes out of the bottle and if everyone turned on the timer at the same time.
