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 Cake Cell

Edible Cells

Edible Cake Cell

-our class is working on cell posters that labels the parts of cells
-we had half of the class working on animal cells and half the class working on plant cells
-we had to draw a picture of the cell then draw the 6-8 parts of the cell and then colour them in

-we will be working on making an edible cell model which has all the parts of the cell
-we have about 45 minutes to brainstorm what materials can be used
-my group is has thought of using vanilla icing as a cell membrane
-the nucleus is a cookie
-the vacuole will be jelly beans
-endoplasmic reticulum is going to be beef jerky and no I'm not kidding
-cytoplasm is going to be the Brownie
-the cell wall will be a fruit roll up
