saliva

So today in room 4 we had to partner up with two other people so that means 3 now. so we were L.S.T and also known as Laolao. Silafaga,Trinity.  We looked under the microscope to see cheek cells.



Hypothesis
We will see some of the organelle in our cheek cell


Equipment
Lolly pop stick
Slide
Sodium Chloride L.S.T
Methylene Blue (stain)


Method
First we put the lolly pop stick inside of our mouth and rubbed our cheek.
Then we wiped the lolly pop stick on the slide
Next we added a drop of sodium chloride on top of the slide
Finally we added a drop of methylene blue to stain the water blue. 
This meant that our slides were ready to go under the microscope.


Why did we need to dye the liquid slide blue? so you can see it
Observation
