ABSTRACT: Ever wonder just how fast your perfume travels?
We
did an experiment to see how long it would take for perfume to travel from one
table to another. My guess was that it would take five minutes to travel from
table to table. Turns out, J-Lo’s perfume travels fast! How long do YOU think
it would take for perfume to travel six meters and 69 centimeters?
Procedure: To start off, Mrs. Thompson brought
some perfume to the class. She faces diagonally to the door and squirted the
bottle twice. As she squirted, Landen set his iPhone timer. Instantly, Ethan
smelt the perfume and raised his hand. Soon after, more and more students
started lifting their hands. After about one minute after the two squirts, I
smelt the perfume and lifted my hand. After about another minute, Jade and
Landen lifted their hands, and the timer stopped. It took two minutes and three
seconds for Jade and Landen to smell the perfume. After the experiment, almost
everyone left the room because the scent of the perfume was very strong!
Data: The results were that it took
two minutes and three seconds for perfume to travel six meters and 69
centimeters. To be exact, for two squirts of perfume.
Conclusion: Although my estimate of five minutes
was very wrong, and the real answer was two minutes and three seconds, this was
fun. I thought that the perfume particles would have taken longer to go from
the high concentration areas, to the low ones and that’s why I guessed five
minutes. I learned that perfume actually travels quite fast! Also I learned
more about diffusion! This experiment taught me that diffusion is when a
substance spreads around and kind of takes over the area! Also now we know that
perfume can really stink up the place!
