perfume diffusion


Perfume diffusion

Steven b

ABSTRACT

This experiment was to see how long it took to diffuse perfume. What we did was we had a teacher spray perfume and for the students to time how long it took to smell it. I thought that it wouldn’t be the brand of perfume but the size of the spray.

Procedure

The procedure of this experiment was that we (the class) walked into the room. Mrs. Thompson had a diagram on the board. The class copied it onto their paper. The teacher measured a ten foot line. The teacher stood on the 0 foot mark and the students stood at the 10 foot mark. The teacher sprayed 2 squirts of spray and the students timed how long it took to smell it. Then the students marked the time. They went for a walk to clear their nose. The class did the same thing over and over. Then they started their diagram. Then they wrote down all the steps.

Data

brand
2 squirts
Time took to diffuse
Beauty rush
Yes
18.70
Okny
yes
18.70
Nspa
Yes
13.70
jlo
no
00.00

 

Conclusion

My hypothesis was that it wouldn’t matter the brand but the size of the 2 squirts. Nspa was the fastest to smell but the squirts were bigger. Jlo didn’t spray so it was disqualified. Okny and beauty rush both took the same amount of time. If we do this experiment again we will have more body spray.

    the only things you missed was that we used devices
    you did not state how your hypothesis was correct
    good luck on your next lab report
